Our main focus is to discern the roles of three α1-adrenergic receptor subtypes (α1A,α1Bandα1D) in physiological and pathophysiological states. All three subtypes are highly homologous in both structure and function, yet evidence suggests that each subtype may play unique roles in signaling and disease states. Our approaches are multi-faceted and multi-disciplined, involving transgenic and knockout mice. Our transgenic mouse models of the α1B subtype develop cardiac hypertrophy, hypotension, and neurodegeneration. However, the α1A subtype appears to be cardioprotective and neuroprotective. Transgenic mice of the α1A subtype protect against ischemic damage in the heart and can precondition against further damage. In the brain, the α1A subtype is anti-epileptic, increases cognitive functions and is involved in neurogenesis. Administration of anα1Aagonist in the drinking water of normal mice increased learning and memory, in addition to increasing neurogenesis. Our work suggests that α1A agonists may offer new therapeutic treatments for cognitive decline, neurodegeneration and myocardial infarction.

Lay Summary

Our body′s “fight or flight” response is regulated through a chemical called adrenaline released through nerve endings. Adrenaline works by attaching to proteins called receptors that are placed in essentially every organ and tissue throughout the body. How one drug can regulate all the organs in the body at the same time and do so in variant ways is through different adrenergic receptors called subtypes. I work on different adrenergic receptor subtypes and can demonstrate how one subtype can protect the heart against damage from heart attacks or can increase your ability to remember things by growing new neurons in the brain.
