T Cell signal transduction involves kinase and transcription factor mediated expression of bioenergetic ensemble gene products. Dr DJ Guerra 23 December 2020

T cell agency initiates upon the stimulation of the TCR via presentation of cognate peptide-MHC complexes in associative ligand-mediated membrane co-receptor CD28 with co-stimulatory molecules presented on the surface of the APC: this event is called T cell licensure and essentially quits quiescence.

The TCR signals through the ERK/MAPK pathways and calcium flux; where as CD28 signaling activates the PI3K-AKT-mTOR axis, and both pathways synergistically engage the NF-κB organon of pleitropic T lymphocyte agency.
