The research in Hamouda’s laboratory at the Fisch College of Pharmacy (FCOP)-University of Texas at Tyler studies the structure, functions and pharmacology of pentameric ligand-gated ion channels especially the nicotinic acetylcholine receptors (nAChRs). Brain nAChRs are important for neuronal survival and for maintenance of cognitive performance and learning during aging and implicated in the pathophysiology of many cognitive and neurodegenerative disorders including Alzheimer’s & Parkinson’s diseases. In addition, neuronal nAChRs play essential roles in the pathophysiology of neuropathic and inflammatory pains and modulation of nAChRs functions produces antinociceptive and anti-inflammatory effects. Furthermore, nAChRs mediate the action of nicotine, the major addictive component of tobacco smoke, and play a major role in the development as well as the treatment of nicotine addiction (cigarette smoking).
Hamouda’s research at the FCOPaims to accelerate the discovery and development of novel therapeutics targeting nAChRs. His current research focuses on nAChR positive allosteric modulators (PAMs) as a novel therapeutic class that selectively target a nAChR subpopulation. He studies the pharmacology of nAChR PAMs in vitro using biophysical and electrophysiology as well as in vivo using animal models for nicotine addiction, Alzheimer’s Disease, and inflammatory pain.
The discovery of selective nAChR PAMs would be significant because there is a critical need for novel strategies to develop potent analgesics that lack the high abuse liability associated with clinically used opioid analgesics. As well as, there is a critical need to develop drugs that enhance cognitive ability in patients with neuropsychiatric disorders and to develop an effective smoking cessation therapy.
