AIBP and regulation of neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS Univ. of Calif., U.C. San Diego Miller, Yury La Jolla, CA 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Persistent pain states arising from inflammatory conditions, such as in arthritis, diabetes, HIV, and chemotherapy, exhibit a common feature in the release of damage-associated molecular pattern molecules, which can activate toll-like receptor-4 (TLR4). Previous studies suggest that TLR4 is critical in mediating the transition from acute to persistent pain. TLR4 as well as other inflammatory receptors localize to lipid raft microdomains on the plasma membrane. We have found that the secreted apoA-I binding protein (AIBP) accelerates cholesterol removal, disrupts lipid rafts, prevents TLR4 dimerization, and inhibits microglia inflammatory responses. We propose that AIBP targets cholesterol removal to lipid rafts harboring activated TLR4. The aims of this proposal are to: 1) determine whether AIBP targets lipid rafts harboring activated TLR4; 2) test whether AIBP reduces glial activation and neuroinflammation in mouse models of neuropathic pain; and 3) identify the origin and function of endogenous AIBP in the spinal cord.

Anatomic, Physiologic and Transcriptomic Mechanisms of Neuropathic Pain in Human DRG Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF TX MD ANDERSON CAN CTR DOUGHERTY, PATRICK M Houston, TX 2020
NOFO Title: Notice of Special Interest for HEAL Initiative: Request for Administrative Supplements to Existing Grants for Identification and Validation of New Pain and Opioid Use Disorder Targets within the Understudied Druggable Genome
NOFO Number: NOT-TR-20-008
Summary:

Using neural tissues from pain patients, this project will investigate mechanisms of neuronal and/or immune dysfunction driving chronic pain. The researchers will use spatial transcriptomics on human dorsal root ganglion (DRG) and spinal cord tissues to examine the cellular expression profile for these targets using the 10X Genomics Visium technology. The use of tissues from control surgical patients and organ donors as well as surgical patients with neuropathic pain will enable validation of expression of these targets in human tissue as well as indication of their potential involvement in neuropathic pain. This collaborative effort will use DRGs removed from pain-phenotyped patients during neurological surgery, as well as lumbar DRGs and spinal cord from organ donors. This study will map the spatial transcriptomes at approximately single cell resolution in the human DRG and spinal cord.

B Lymphocyte-Mediated Autoimmunity in Pain After Trauma Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS PALO ALTO VETERANS INSTIT FOR RESEARCH CLARK, DAVID J Palo Alto, CA 2020
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

A major recent advancement for the field of pain research is the recognition of immune system dysregulation as a contributor to the most serious adverse consequences of pain from injury. Accumulating data from clinical and laboratory studies place the activation of B lymphocytes at the center of much of this work, particularly with respect to chronic pain and disability-related outcomes. Validation of this B cell hypothesis could lead directly to trials testing the efficacy of novel or existing immunomodulating agents on posttraumatic pain. To achieve these goals a well-validated core mouse model of limb fracture will be employed with additional studies to be conducted in incisional and nerve injury models to broaden the assessment of B cell mediated effects on pain. Age and sex will be included as variables to enhance rigor.

Cellular and Molecular Role of CXCR4 signaling in Painful Diabetic Neuropathy Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS Northwestern University MENICHELLA, DANIELA M Evanston, IL 2019
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Neuropathic pain is a debilitating affliction present in 26% of diabetic patients, with substantial impact on the quality of life. Despite this significant impact and prevalence, current therapies for painful diabetic neuropathy (PDN) are only partially effective, and the molecular mechanisms underlying neuropathic pain in diabetes are not well understood. Our long-term goal is to elucidate the molecular mechanisms responsible for PDN in order to provide targets for the development of therapeutic agents. Our objective is to identify the molecular cascade linking CXCR4/SDF-1 chemokine signaling to DRG nociceptor hyper-excitability, neuropathic pain, and small fiber degeneration. Our aims will determine: 1) the ion-channel current profile of the nociceptor hyper-excitable state produced by CXCR4/SDF-1 signaling in PDN; 2) the gene expression profile of the nociceptor hyper-excitable state produced by CXCR4/SDF-1 signaling in PDN; and 3) the specific features of nociceptor mitochondrial dysfunction produced by CXCR4/SDF-1 signaling in PDN.

Clustering of individual and diverse ion channels together into complexes, and their functional coupling, mediated by A-kinase anchoring protein 79/150 in neurons Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF TEXAS HLTH SCI CTR SAN ANTONIO SHAPIRO, MARK S San Antonio, TX 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Multi-protein complexes have emerged as a mechanism for spatiotemporal specificity and efficiency in the function and regulation of cellular signals. Many ion channels are clustered either with the receptors that modulate them or with other ion channels whose activities are linked. Often, the clustering is mediated by scaffolding proteins, such as AKAP79/150. We will probe complexes containing AKAP79/150 and three different channels critical to nervous function: KCNQ/Kv7, TRPV1, and CaV1.2. We will use"super-resolution" STORM imaging of primary sensory neurons and heterologously expressed tissue-culture cells, in which individual complexes can be visualized at 10–20 nm resolution with visible light. We hypothesize that AKAP79/150 brings several of these channels together to enable functional coupling, which we will examine by patch-clamp electrophysiology of the neurons. Since all three of these channels bind to AKAP79/150, we hypothesize that they co-assemble into complexes in neurons and that they are dynamically regulated by other cellular signals.

CMG2 as a Target for Safe and Effective Treatment of Endometriosis-Associated Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NICHD BOSTON CHILDREN'S HOSPITAL ROGERS, MICHAEL SEAN Boston, MA 2022
NOFO Title: HEAL Initiative: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: NS22-034
Summary:

Endometriosis is an often-painful disorder in which uterine tissue grows outside the uterus. Treatment of endometriosis-associated pain involves use of opioids in many women. This project aims to study a culprit gene thought to be involved with the disorder (capillary morphogenesis gene or CMG2) as a target for new, nonopioid pain medications. The research will also clarify how CMG2 s affects endometriosis-associated pain to test the effects of new medications for endometriosis pain.

Development and Optimization of MNK Inhibitors for the Treatment of Neuropathic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS 4E THERAPEUTICS INC. SAHN, JAMES JEFFREY Austin, TX 2020
NOFO Title: Notice of Special Interest for HEAL Initiative: Request for Administrative Supplements to Existing Grants for Identification and Validation of New Pain and Opioid Use Disorder Targets within the Understudied Druggable Genome
NOFO Number: NOT-TR-20-008
Summary:

There is an urgent unmet need for more efficacious analgesics that act via a non-opioid pathway. Mitogen Activated Protein Kinase-interacting kinase 2 (MNK2) is an enzyme that has been implicated in pain signaling, and there is compelling evidence that inhibiting MNK2 has significant pain-reducing effects with few side-effects. Since MNK2 selective inhibitors have not yet been identified, selective inhibition of MNK2 with a small molecule has not been possible. The development of such compounds will enable studies that will illuminate key differences between MNK2 and MNK1. More importantly, from a therapeutic standpoint, highly selective MNK2 inhibitors may prove to have enhanced efficacy and a more favorable side-effect profile than molecules that inhibit both MNK2 and MNK1. This project will support the design and synthesis of at least one MNK2 inhibitor, with >100-fold selectivity over MNK1, that may be developed into a lead compound for treating neuropathic pain.

Discovery and validation of a new long noncoding RNA as a novel target for neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS RBHS-NEW JERSEY MEDICAL SCHOOL TAO, YUAN-XIANG Newark, NJ 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Identification of new targets and mechanisms underlying chronic neuropathic pain is essential for the discovery of novel treatments and preventative tactics for better neuropathic pain management. A recent exploration of next-generation RNA sequencing identified a large, native, full-length long noncoding RNA (lncRNA) in mouse and human dorsal root ganglion (DRG). It was named as nerve injury-specific lncRNA (NIS-lncRNA), since its expression was found increased in injured DRGs, in response to peripheral nerve injury, but not in response to inflammation. Preliminary findings revealed that blocking the nerve injury-induced increases in DRG NIS-lncRNA levels ameliorated neuropathic pain. This project will validate NIS-lncRNA as a therapeutic target in animal models of neuropathic pain and in cell-based functional assays utilizing human DRG neurons. Completion of this proposal will advance neuropathic pain management and might provide a novel, non-opioid pain therapeutic target.

Discovery and validation of a novel orphan GPCR as a target for therapeutic intervention in neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS St. Louis University SALVEMINI, DANIELA St. Louis, MO 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Neuropathic pain conditions are exceedingly difficult to treat, and novel non-opioid analgesics are desperately needed. Receptomic and unbiased transcriptomic approaches recently identified the orphan G-protein coupled receptor (oGPCR), GPR160, as a major oGPCR whose transcript is significantly increased in the dorsal horn of the spinal cord (DH-SC) ipsilateral to nerve injury, in a model of traumatic nerve-injury induced neuropathic pain caused by constriction of the sciatic nerve in rats (CCI). De-orphanization of GPR160 led to the identification of cocaine- and amphetamine-regulated transcript peptide (CARTp) as a ligand which activates pathways crucial to persistent pain sensitization. This project will test the hypothesis that CARTp/GPR160 signaling in the spinal cord is essential for the development and maintenance of neuropathic pain states. It will also validate GPR160 as a non-opioid receptor target for therapeutic intervention in neuropathic pain, and characterize GPR160 coupling and downstream molecular signaling pathways underlying chronic neuropathic pain.

Discovery of Novel Openers of the Understudied Human Drug Target Kir6.1 Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NCATS NEW YORK UNIVERSITY SCHOOL OF MEDICINE CARDOZO, TIMOTHY J New York, NY 2022
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: TR22-011
Summary:

Routine treatment of pain with prescription opioid medications may evolve into opioid use disorder, addiction, and potentially overdose. New, non-opioid molecular targets for pain are needed as a key element of responding to the opioid and overdose crisis. Ion channels are molecular gateways that convert electrical signals into physiological responses, and many have been implicated in transmitting pain signals. The ion channel Kir6.1/KCNJ8 has been linked to the control of postoperative and cancer pain. Studies in animal models show that low levels of this ion channel are evident after an injury. This research will identify compounds that can open the Kir6.1/KCNJ8 channel as potential treatment strategy for pain.

Discovery of the Novel Targets for Post-Traumatic Headache Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS WASHINGTON UNIVERSITY CAO, YUQING Saint Louis, MO 2023
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: RFA-TR-22-011
Summary:

Chronic post-traumatic headache (PTH) is highly debilitating, poorly understood, and difficult to treat. This project aims to identify proteins located in the membrane of certain neurons that are critical for the development, maintenance, and/or resolution of PTH. These proteins may be targets for novel treatment approaches that are nonaddictive and have minimal side effects.

Disrupting ion channel scaffolding to treat neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS STATE UNIVERSITY OF NEW YORK AT BUFFALO BHATTACHARJEE, ARINDAM Buffalo, NY 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Dorsal root ganglion (DRG) neuronal hyperexcitability is central to the pathology of neuropathic pain and is a target for local anesthetics, even though the efficacy of local anesthetic patches has been mixed. The coordinated movement of ion channels, especially voltage-dependent sodium channels, from intracellular pools to the sites of nerve injury has been suggested to be an underlying cause of electrogenesis and ectopic firing in neuropathic pain conditions. Recent studies identified Magi1 as a scaffold protein responsible for sodium channel targeting and membrane stabilization in DRG neurons. This project will determine whether reducing the expression Magi1 could disrupt intracellular trafficking of sodium channels in DRG neurons under neuropathic injury conditions, and could therefore serve as a potential therapeutic target for neuropathic pain.

Dnmt3a as an epigenetic target for chronic pain treatment Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF TX MD ANDERSON CAN CTR PAN, ZHIZHONG Z Houston, TX 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

It is unclear what changes in the brain mediate the development of chronic pain from acute pain and how chronic pain may change responses to opioid reward for the altered liability of opioid abuse under chronic pain. Preliminary studies have found that Dnmt3a, a DNA methyltransferase that catalyzes DNA methylation for gene repression, is significantly downregulated in the brain in a time-dependent manner during the development of chronic pain and after repeated opioid treatment. This project will investigate whether Dnmt3a acts as a key protein in the brain for the development of chronic pain, and whether Dnmt3a could be a novel epigenetic target for the development of new drugs and therapeutic options for the treatment of chronic pain while decreasing abuse liability of opioids.

Erythrocyte Autophagy Proteins as Potential Non-Opioid Novel Targets for Pain in Sickle Cell Disease Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NCCIH UNIVERSITY OF ILLINOIS, CHICAGO RAMASAMY, JAGADEESH Chicago, IL 2022
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: TR22-011
Summary:

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and over 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Painful episodes that require hospitalization and, in many cases, opioid treatment, are a hallmark of sickle cell disease. The source of these painful episodes remains unclear, and it is also unknown why pain severity varies so much among affected individuals. This project will identify novel, non-opioid targets to reduce sickle cell-related pain and search for biomarkers to help clinicians predict which individuals are at risk for increased pain, thereby improving health outcomes for people with sickle cell disease.

Exploration of MBD1 as a Therapeutic Target for Chronic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NCATS UNIVERSITY OF MINNESOTA STONE, LAURA S Minneapolis, MN 2023
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: RFA-TR-22-011
Summary:

Chronic pain results in long-term changes throughout the central nervous system. These include abnormal structure and function of the frontal cortex region of the brain, which relays pain messages and also the common pain-related conditions depression, anxiety, and cognitive impairment. Peripheral nerve injury results in widespread and long-lasting changes to DNA in the frontal cortex. DNA methylation, in which chemical tags are attached to DNA, is one way the body controls the activity of genes over time. This control occurs via proteins that recognize tagged DNA, and some of these proteins do not work properly in the frontal cortex many months after nerve injury. These changes occur after nerve injury and are linked to mechanical sensitivity. This project will determine this DNA-binding protein is a good target for finding new medications for chronic pain.

FKBP51 Antagonism to Prevent Chronic Pain: Optimizing Efficacy & Evaluating Safety and Mechanisms Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIV OF NORTH CAROLINA CHAPEL HILL LINNSTAEDT, SARAH ; MCLEAN, SAMUEL A Chapel Hill, NC 2020
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

A substantial proportion of Americans seeking emergency care after traumatic stress exposure (TSE) are at a high risk of chronic pain and opioid use/misuse. Physiologic systems involved in the stress response could possibly play a critical role in the development of chronic pain after TSE. FK506-binding protein 51 (FKBP51) is an intracellular protein known to affect glucocorticoid negative feedback inhibition and component of stress response, provides an important non-opioid therapeutic target for such chronic pain. This project will test the hypothesis that functional inhibition of FKBP51 prevents or reduces enduring stress-induced hyperalgesia in a timing, dose, and duration-dependent manner in animal models of single prolonged stress alone and in combination with surgery. This project will also test if FKBP51 inhibition enhances recovery following TSE via reduction in pro-inflammatory responses in peripheral and central tissues. It will also test whether FKBP51 inhibition effects cardiotoxicity or addiction. Completion of these studies will increase understanding of FKBP51 as a novel therapeutic target for the prevention of chronic pain and opioid use/misuse resulting from TSE.

G Alpha Z Subunit as a Potential Therapeutic Target to Modulate Mu Opioid Receptor Pharmacology Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDA UNIVERSITY OF ROCHESTER BIDLACK, JEAN M Rochester, NY 2022
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: TR22-011
Summary:

Opioids affect the body by attaching to certain types of receptors that attach to G-proteins (particularly, a subtype called G-alpha). Opioids vary in their ability to provide pain relief as well as in their ability to require more drug to provide a response, known as tolerance. This project will explore the potential of various G-alpha subunits to increase or decrease opioid receptor signaling. The research findings will lay the groundwork for tailoring G-alpha related opioid effects to provide more pain relief while being less addictive.

Genetic and Pharmacological Validation of CRMP2 Phosphorylation as a Novel therapeutic Target for Neuropathic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF ARIZONA KHANNA, RAJESH Tucson, AZ 2020
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Peripheral nerve injury-induced upregulation of three axonal guidance phosphoproteins correlates with the development of neuropathic pain through an unidentified mechanism: 1) collapsin response mediator protein 2 (CRMP2); 2) the N-type voltage-gated calcium (CaV2.2); 3) the NaV1.7 voltage-gated sodium channel. Injury induced phosphorylated-CRMP2/CaV2.2 and phosphorylated-CRMP2/NaV1.7 upregulation in the sensory pathway may promote abnormal excitatory synaptic transmission in spinal cord that leads to neuropathic pain states. This project will validate CRMP2 phosphorylation as a novel target in neuropathic pain using innovative tools. Examples include a genetic approach (crmp2S522A) in mice as well as a non-opioid pharmacological approach (a novel CRMP2-phsphorylation targeting compound). Demonstrating that inhibition of CRMP2 phosphorylation reverses or prevents neuropathic pain will promote the discovery and validation of a novel therapeutic target (CRMP2-phosphorylation) to facilitate the development of novel pain therapeutics.

Identification and Validation of a Novel Central Analgesia Circuit Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR DUKE UNIVERSITY WANG, FAN Durham, NC 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

This project focuses on identifying and validating a new central analgesic circuit in the brain, based on a highly innovative hypothesis that the strong analgesic effects of general anesthesia (GA) are in part carried out by GA-mediated activation of the endogenous analgesic circuits. Preliminary discovery studies found that a subset of GABAergic neurons located in the central amygdala (CeA) become strongly activated and express high levels of the immediate early gene Fos under GA (hereafter referred to as CeAGA neurons). Furthermore, activation of these neurons exert profound pain-suppressing effects in an acute pain model and a chronic orofacial neuropathic pain model in mice. Based on these exciting preliminary findings, this project will identify and validate CeAGA neurons’ analgesic functions utilizing multiple mouse pain models. Identification of these shared common pathways that need to be suppressed by specific subtypes of CeAGA analgesic neurons will be highly critical for developing precise CeAGA-targeted therapies to treat chronic pain.

Identification of Novel Targets for the Treatment of Chemotherapy-Induced Painful Peripheral Neuropathy Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF MARYLAND BALTIMORE MELEMEDJIAN, OHANNES KEVORK Baltimore, MD 2020
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Chemotherapy-induced painful peripheral neuropathy (CIPN) is the most common toxicity associated with widely used chemotherapeutics. CIPN accounts for significant dose reductions and/or discontinuation of these life-saving treatments. Unfortunately CIPN can also persist in cancer-survivors, adversely affecting their quality of life. CIPN is not well-managed with existing pain therapeutics. Recent preliminary findings suggest that the transcription factor hypoxia-inducible factor alpha (HIF1A) is the target for the chemotherapeutic bortezomib, a proteasome inhibitor. This project will test the hypothesis that bortezomib chemotherapy-induced expression of HIF1A, PDHK1 and LDHA constitute an altered metabolic state known as aerobic glycolysis (AG) that leads to the initiation and maintenance of peripheral neuropathy and pain using a novel tumor-bearing animal model of CIPN. This project aims to validate HIF1A as a therapeutic target for the prevention of CIPN, as well as validate PDHK1 and LDHA as non-opioid therapeutic targets for chronic or established CIPN in animal models.

Immune Modulating Therapies to Treat Complex Regional Pain Syndrome Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS DREXEL UNIVERSITY AJIT, SEENA Philadelphia, PA 2022
NOFO Title: HEAL Initiative: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: NS22-034
Summary:

Complex regional pain syndrome is a difficult-to-treat chronic condition that causes excess and prolonged pain and inflammation after injury to an arm or leg and includes damage to skin of affected limbs. Although it is known that aberrant immune system function plays a role in this condition, the details remain unclear about how this occurs – in particular, through the adaptive immune system that relies on specialized immune cells and antibodies to protect the body from harm.  This project will study the role of certain immune cells (T cells) that circulate throughout the body or reside in bone using both rat or human bone samples from patients with complex regional pain syndrome.
