antigenic modulation
the alteration of antigenic determinants in a living cell surface membrane following interaction with an antibody.
covalent modulation
activation or inactivation of enzymes, either by phosphorylation/dephosphorylation or by proteolytic cleavage. A major means of regulation of enzyme action by hormones.
