Cell to cell signaling
refers to the transfer of information from one cell to another. This is also
called cell signaling or intercellular communication. 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 cellular information
processing are responsible for diseases such as cancer, autoimmunity, and
diabetes. The cells of the body communicate with each other through some
chemical substances called chemical
messengers. These chemical messengers are extracellular
signaling molecules e.g., hormones and neurotransmitters. Cells signals by releasing these molecules that bind to
receptor proteins located in the plasma membrane, cytoplasm, or nucleus.
This signal is transduced into the activation, or inactivation, of one or more
intercellular messengers by interacting with receptors. Receptors interact with
a variety of intracellular signaling proteins, including kinases,
phosphatases, and GTP-binding proteins (G proteins). These signaling
proteins interact with and regulate the activity of target proteins and thereby
modulate cellular function.
