General principles of cellular communication

Learn about how cells sense and respond to extrinsic stimuli, a capacity that allows them to communicate with each other and to respond to changes in their environment. This free course, General principles of cellular communication, explains cell signalling pathways in general terms and identifies some of the universal characteristics of signalling pathway components.
