aka intracellular signaling, not to be confused with Intracrine signaling)
Intracellular (within a Cell) processes networks (of protein interactions) to respond and generate signals for Cell signaling

Signalling pathways
Molecular switches
Kinase signalling cascade (via Phosphorylation)
amplification
scaffolding. different signals with same molecules
Second messengers
Intermediary signals, that often ends with activate Kinases
Calcium signalling
Feedback generates Calcium ion waves and oscillatoions.
