The goal of this course is to provide an in-depth descrip-tion of the molecular mechanisms of ligand-receptor binding and signal transduction. Emphasis is placed on the mechanism of action of hormones, neurotransmitters, and growth factors. Individual components of receptor-induced signaling pathways are investigated in detail and integrated into models of cellular control. Relies heavily on current literature and student-directed discussion. Offered alternate years. Kandror. 2 cr, 2nd sem.
