CD4-positive T Cell Activation via TB10.4 Antigen Presentation (TB10.4-CD4+ T cell activation)

Target

Molecular classification
Immune cell activation, Antigen presentation, T cell signaling
01

Overview

CD4-positive T cell activation via TB10.4 antigen presentation refers to the process by which CD4+ T helper cells are specifically activated in response to the Mycobacterium tuberculosis (Mtb) antigen known as TB10.4. This process is central to mounting an adaptive immune response against Mtb infection, involving antigen processing by APCs, MHC-II presentation, TCR/CD4 engagement, costimulation, and downstream signaling leading to T cell proliferation, differentiation, and cytokine secretion. TB10.4 is an immunodominant antigen recognized by both CD4+ and CD8+ T cells. Variations in processing or sequence polymorphisms within antigens like TB10.4 can shift immunodominance patterns. Full activation requires specific recognition through the peptide/MHC-TCR axis and costimulatory signals; otherwise tolerance may be induced.
