Cell Signaling

Cell signalling is part of any communication process that governs basic activities of cell and coordinates all cell actions. The ability of cells to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity as well as normal tissue homeostasis. Errors in signalling interactions and cellular information processing are responsible for diseases such as cancer autoimmunity and diabetes.Cells have proteins called receptors that bind to signalling molecule and initiate a physiological response. Receptors transform external signals into internal ones via protein action, ion channel opening or enzyme activation.
