The Dual-Signal Requirement for T-Cell Activation

A cornerstone principle discussed in Abbas’s 8th edition is that naive T cells require two distinct signals for full activation. Signal 1 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.

The text is structured to guide students from basic properties to specialized immune functions: Fundamental Principles: NFAT (nuclear factor of activated T cells): Activated

Scribd: Hosts several PDF versions of the 8th edition uploaded by users for online reading.

Edition: 8th Edition (Spanish translation released around 2015-2018). Publisher: Elsevier.

1. NFAT (nuclear factor of activated T cells): Activated by calcium/calcineurin signaling following PLC-γ1-mediated IP3 production and calcium release.
2. NF-κB: Activated via PKC-θ and CARMA1-BCL10-MALT1 complex.
3. AP-1 (Fos/Jun): Induced by the MAP kinase pathway (Ras-Raf-MEK-ERK).
