Regulatory mechanisms refer to the processes and systems that control and coordinate the activities of cells, organisms, or systems to maintain homeostasis and ensure proper functioning. These mechanisms involve complex networks of molecules, proteins, and genes that govern various biological processes such as gene expression, cell signaling, and metabolism. Regulatory mechanisms play a crucial role in determining the response of organisms to internal and external stimuli, and dysregulation of these processes can lead to disease and dysfunction. Researchers in this field study the mechanisms involved in regulating biological processes at the molecular, cellular, and organismal levels, with the goal of better understanding health and disease and developing new therapeutic strategies.
