Cellular Biology Cell Signalling
Cellular Biology Cell Signalling pertains to the complex process by which cells communicate with each other to regulate various physiological functions. This includes the transmission of signals through molecular pathways within cells, involving receptors, proteins, and other molecules that work together to coordinate cellular activities. Signalling can occur through various mechanisms, such as chemical messengers, receptor-ligand interactions, and signal transduction cascades, ultimately leading to changes in gene expression, cell growth, metabolism, and other cellular responses. Understanding cell signalling is crucial for unraveling the mechanisms underlying normal cellular processes and diseases, and for developing targeted therapies to modulate signalling pathways.
