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.

LIGHT and Lymphotoxin targeting for the treatment of chronic orofacial pain conditions Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR UNIVERSITY OF TEXAS HLTH SCIENCE CENTER AKOPIAN, ARMEN N San Antonio, 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:

Mismanagement of orofacial chronic pain, such as temporomandibular joint and muscle disorders (TMJD) and oral cancer, substantially contributes to opioid overuse; overdose-related deaths; and cardiovascular, renal, and neurological complications at epidemic proportions. The current paradigm implies that orofacial conditions could trigger maladaptation of the immune system and plasticity supporting persistent inflammation, which influences the development and maintenance of orofacial chronic pain. LIGHT (TNFSF14) and Lymphotoxin-beta (LT?), members of the tumor necrosis factor superfamily, provide a balance between protective immunity and immunopathology during chronic inflammatory diseases. This project will test the hypothesis that targeting LIGHT and LT? signaling could prevent the development and inhibit the maintenance of chronic pain produced by TMJD and oral cancer, via peripheral mechanisms involving plasticity of immune, stromal, and tumor cells, as well as sensory neurons. The proposed research is significant as it advances our understanding of mechanisms regulating the development and maintenance of orofacial pain and offers new therapeutic targets and an immunotherapeutic approach for preventing and blocking chronic pain during TMJD and oral cancer.

Comprehensive Functional Phenotyping of Trigeminal Neurons Innervating Temporomandibular Joint (TMJ) Tissues in Male, Female and Aged Mice, Primates, and Humans With and Without TMJ Disorders (TMJD) Preclinical and Translational Research in Pain Management Restoring Joint Health and Function to Reduce Pain (RE-JOIN) NIAMS UNIVERSITY OF TEXAS HLTH SCIENCE CENTER AKOPIAN, ARMEN N; BOADA, MARIO DANILO; ERNBERG, MALIN; MACPHERSON, LINDSEY J San Antonio, TX 2022
NOFO Title: HEAL Initiative: Restoring Joint Health and Function to Reduce Pain Consortium (RE-JOIN) (UC2 Clinical Trial Not Allowed)
NOFO Number: RFA-AR-22-009
Summary:

Scientists do not know the details of how the nervous system interacts with the temporomandibular joint (TMJ) that connects the lower jaw with the skull. This project aims to comprehensively explain the functions, types, neuroanatomical distributions, and adaptability (plasticity) of specific nerve cells in the brain (trigeminal neurons) that connect with the TMJ. The research will analyze nerve-TMJ connections associated with chewing muscles and other structures that form the TMJ such as cartilage and ligaments. The project will analyze samples from both sexes of aged mice, primates, and humans with and without painful TMJ disorders. This research aims to uncover potential treatment and prevention targets for managing TMJ pain.

NOFO Title: Notice of Special Interest to Encourage Eligible NIH HEAL Initiative Awardees to Apply for PA-18-906 Research Supplements to Promote Diversity in Health-Related Research (Admin Supp - Clinical Trial Not Allowed)
NOFO Number: NOT-NS-20-023
Summary:

Chronic orofacial pain during Temporomandibular Disorders (TMD) and oral cancer is a significant health problem with scarce non-opioid treatment options. This study aims to validate critical regulators of the balance between protective immunity and immunopathology during chronic inflammatory diseases?tumor necrosis factor alpha superfamily members, LIGHT (TNFSF14) and lymphotoxin-beta (LT?) and their receptors, LT?R and Herpes Virus Entry Mediator (HVEM)?as novel therapeutic targets. The study also seeks to determine whether inhibition of LIGHT and LT? signaling prevents the development and inhibits maintenance of chronic TMD and oral cancer pain via peripheral mechanisms involving plasticity of immune, muscle and tumor cells as well as sensory neurons. The study will define the contribution of LIGHT and LT? signaling to TMD-induced excitability of trigeminal sensory neurons innervating the masseter muscle and joint. New validated therapeutic targets for prevention and treatment of orofacial pain that can be peripherally targeted would reduce side effects of current pain medicates related to drug dependence or tolerance.

3/3 Promoting Resilience in Children: Protocol Development for a Birth Cohort Study To Assess Factors Impacting Neurodevelopment Enhanced Outcomes for Infants and Children Exposed to Opioids HEALthy Brain and Child Development Study (HBCD) NIDA UNIVERSITY OF WISCONSIN-MADISON ALEXANDER, ANDREW L Madison, WI 2019
NOFO Title: HEAL Initiative: HEALthy Brain and Child Development Study (HEALthy BCD) (Collaborative R34 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-19-029
Summary:

The first ten years of life are accompanied by rapid changes to the developing brain and cognitive abilities. Complex interacting factors including genetics, early-life exposure to substances, family and social interactions, and home and community environments can affect brain and cognitive development. Three linked projects aim to develop effective research protocols to lay a foundation for a future HEALthy Brain and Cognitive Development (HBCD) birth cohort study. Project 1 will develop protocols for recruitment and retention of a diverse sample of pregnant and postpartum women with oversampling of mothers with prenatal opioid use. Project 2 will identify ethical, legal, and regulatory challenges for investigations in this vulnerable population and define effective solutions to enable recruitment and study of these participants. Project 3 will develop and evaluate protocols for acquiring high-quality, quantitative neuroimaging measures with magnetic resonance imaging and functional near infrared spectroscopy and assess effective strategies for measuring cognitive performance in young children, including those exposed to opioids.
