Cell Communication
Cell Communication
Communication between cells requires:
ligand: the signaling molecule
receptor protein: the molecule to which the
ligand binds
(may be on the plasma membrane or
within the cell)

Cell Communication
There are four basic mechanisms for
cellular communication:
1. direct contact
2. paracrine signaling
3. endocrine signaling
4. synaptic signaling
