Alfred G. Gilman

Alfred G. Gilman was a renowned American pharmacologist and biochemist who, along with his colleague Martin Rodbell, discovered G proteins—molecular switches that regulate how cells respond to signals like hormones and neurotransmitters. This groundbreaking work helped clarify how cells communicate and coordinate their actions. Gilman’s research contributed significantly to understanding cell signaling pathways, which are vital for normal bodily functions. He was awarded the Nobel Prize in Physiology or Medicine in 1994 for these discoveries. His work has had a lasting impact on medicine, particularly in developing treatments for diseases that involve cell signaling errors.
