#Unit 4. Cell Communication and Cell Signaling

A cell can become more or less susceptible to the actions of a ligand by increasing (up-regulating) or decreasing (down[1]regulating) the expression of the receptor for that li
Ligand binding to the receptor induces a molecular change in the receptor. This change may be in the form of a conformational alteration in the receptor, receptor dimerization or clustering, a change in the receptor’s location in the membrane, or a covalent modification.
a cell must not receive more than one signal through more than one receptor in order to effect a particular outcome.
Integration of all the signals received by a cell occurs at the molecular level inside the recipient cell.
