#Unit 4. Cell Communication and Cell Signaling

CD28 on the T cell and CD80/86 (B7) on the APC provided the costimulatory signal required for T-cell activation.

#Unit 4. Cell Communication and Cell Signaling

An antigen presented to T cells without appropriate costimulation results in a form of tolerance known as anergy.

#Unit 4. Cell Communication and Cell Signaling

Third mechanism for maintaining tolerance, in addition to T-cell anergy and apoptosis, is through the activity of regulatory T cells (TREG cells).

#Unit 4. Cell Communication and Cell Signaling

TREG can be generated both naturally, in the thymus (nTREG cells), and after induction by antigen in the periphery (iTREG cells).
