A cornerstone principle discussed in Abbas’s 8th edition is that naive T cells require two distinct signals for full activation. is delivered through the TCR upon recognition of a peptide-MHC complex. Signal 2 is provided by co-stimulatory molecules, most notably CD28 on the T cell engaging CD80 (B7-1) or CD86 (B7-2) on antigen-presenting cells (APCs). Without signal 2, the T cell becomes anergic or undergoes apoptosis – a critical mechanism of peripheral tolerance. Page 2618 likely expands on the biochemical consequences of these signals, detailing how they integrate to lower the threshold for T-cell proliferation and cytokine production.
