- Abstract
Protein kinase C molecules regulate both positive and negative signal transduction pathways essential for the initiation and homeostasis of immune responses. There are multiple isoforms of protein kinase C that are activated differently by calcium and diacylglycerol, and these are activated mainly by antigen receptors in T cells, B cells and mast cells. Additionally, mammals express several other diacylglycerol binding proteins that are linked to a network of key signal transduction pathways that control lymphocyte biology. Diacylglycerol and protein kinase C regulate a broad range of gene transcription programs but also modulate integrins, chemokine responses and antigen receptors, thereby regulating lymphocyte adhesion, migration, differentiation and proliferation.
