  • Nociceptor Translational Profiling Reveals the Ragulator-Rag GTPase Complex as a Critical Generator of Neuropathic Pain 

    Megat, Salim; Ray, Pradipta R.; Moy, Jamie K.; Lou, Tzu-Fang; Barragan-Iglesias, Paulino; Li, Yan; Pradhan, Grishma; Wanghzou, Andi; Ahmad, Ayesha; Burton, Michael D.; North, Robert Y.; Dougherty, Patrick M.; Khoutorsky, Arkady; Sonenberg, Nahum; Webster, Nevin R.; Dussor, Gregory; Campbell, Zachary T.; Price, Theodore J. (Soc Neuroscience, 2019-01-16)
    Nociceptors, sensory neurons in the DRG that detect damaging or potentially damaging stimuli, are key drivers of neuropathic pain. Injury to these neurons causes activation of translation regulation signaling, including ...
  • Emerging Neurotechnology for Antinoceptive Mechanisms and Therapeutics Discovery 

    Black, Bryan J.; Atmaramani, Rahul; Plagens, Sarah; Campbell, Zachary T.; Dussor, Gregory; Price, Theodore J.; Pancrazio, Joseph J. (Elsevier Advanced Technology, 2018-11-13)
    The tolerance, abuse, and potential exacerbation associated with classical chronic pain medications such as opioids creates a need for alternative therapeutics. Phenotypic screening provides a complementary approach to ...
  • The Antidiabetic Drug Metformin Prevents and Reverses Neuropathic Pain and Spinal Cord Microglial Activation in Male but not Female Mice 

    Inyang, Kufreobong E.; Szabo-Pardi, Thomas; Wentworth, Emma; McDougal, Timothy A.; Dussor, Gregory; Burton, Michael D.; Price, Theodore J. (Academic Press Ltd- Elsevier Science Ltd, 2018-11-01)
    Metformin is a widely prescribed drug used in the treatment of type II diabetes. While the drug has many mechanisms of action, most of these converge on AMP activated protein kinase (AMPK), which metformin activates. AMPK ...
  • Activation of the Integrated Stress Response in Nociceptors Drives Methylglyoxal-Induced Pain 

    Barragan-Iglesias, Paulino; Kuhn, Jasper; Vidal-Cantu, Guadalupe C.; Belen Salinas-Abarca, Ana; Granados-Soto, Vinicio; Dussor, Gregory; Campbell, Zachary T.; Price, Theodore J. (Lippincott Williams & Wilkins, 2019-01)
    Methylglyoxal (MGO) is a reactive glycolytic metabolite associated with painful diabetic neuropathy at plasma concentrations between 500 nM and 5 μM. The mechanisms through which MGO causes neuropathic pain at these ...
  • Protease Activated Receptor 2 (PAR2) Activation Causes Migraine-Like Pain Behaviors in Mice 

    Hassler, Shayne N.; Ahmad, Fatima B.; Burgos-Vega, Carolina C.; Boitano, Scott; Vagner, Josef; Price, Theodore J.; Dussor, Gregory (Sage Publications Ltd, 2018-05-31)
    Background Pain is the most debilitating symptom of migraine. The cause of migraine pain likely requires activation of meningeal nociceptors. Mast cell degranulation, with subsequent meningeal nociceptor activation, has ...
  • Non-Invasive Dural Stimulation in Mice: A Novel Preclinical Model of Migraine 

    Burgos-Vega, Carolina Christina; Quigley, Lilyana D.; dos Santos, Gabriela Trevisan; Yan, Flora; Asiedu, Marina; Jacobs, Blaine; Motina, Marina; Safdar, Nida; Yousuf, Hayyan; Avona, Amanda; Price, Theodore J.; Dussor, Greg (Sage Publications Ltd, 2018-05-31)
    Background Migraine is characterized by a collection of neurological symptoms in the absence of injury or damage. However, several common preclinical migraine models require significant damage to the skull to stimulate the ...
  • Dural Calcitonin Gene-Related Peptide Produces Female-Specific Responses in Rodent Migraine Models 

    Avona, Amanda; Burgos-Vega, Carolina; Burton, Michael D.; Akopian, A. N.; Price, Theodore J.; Dussor, Gregory (Society for Neuroscience, 2019-05-29)
    Migraine is the second leading cause for disability worldwide and the most common neurological disorder. It is also three times more common in women; reasons for this sex difference are not known. Using preclinical behavioral ...
  • Sex Differences in the Expression of Calcitonin Gene-Related Peptide Receptor Components in the Spinal Trigeminal Nucleus 

    Ji, Y.; Rizk, A.; Voulalas, P.; Aljohani, H.; Akerman, S.; Dussor, Gregory; Keller, A.; Masri, R. (Elsevier B.V., 2019-04-24)
    Background and purpose: Calcitonin gene-related peptide (CGRP) plays an important role in migraine pathophysiology. CGRP acts primarily by activating a receptor composed of 3 proteins: calcitonin receptor-like receptor ...
  • Transcriptome Analysis of the Human Tibial Nerve Identifies Sexually Dimorphic Expression of Genes Involved in Pain, Inflammation, and Neuro-Immunity 

    Ray, Pradipta R.; Khan, Jawad; Wangzhou, Andi; Tavares-Ferreira, Diana; Akopian, A. N.; Dussor, Gregory; Price, Theodore J.
    Sex differences in gene expression are important contributors to normal physiology and mechanisms of disease. This is increasingly apparent in understanding and potentially treating chronic pain where molecular mechanisms ...
  • Spinal Inhibition of P2XR or p38 Signaling Disrupts Hyperalgesic Priming in Male, but not Female, Mice 

    Paige, Candler; Maruthy, Gayathri B.; Mejia, Galo; Dussor, Gregory; Price, Theodore J.
    Recent studies have demonstrated sexual dimorphisms in the mechanisms contributing to the development of chronic pain. Here we tested the hypothesis that microglia might preferentially regulate hyperalgesic priming in male ...
