T Cell Differentiation Pathway Ebsa elemo immunology for mls studentall health lecturer. T cells are major components of the adaptive immune system. they can differentiate into two different populations of effector cells type one and type two and may also become tolerant. t cells respond to immune challenges by interacting with antigen presenting cells of the innate immune system. these latter cells can identify the nature of any. Within the cd4 population, we analyzed markers commonly related to t cell activation (hla dr and cd38), senescence and exhaustion (cd57 and pd1), differentiation (cd45ra, ccr7, cd28, and cd27. A basal nf‐κb activity is important for the survival, differentiation, and full activation of t cells, whatever the cytokine profile. the nf‐κb family has an intrinsic role in type one effector function, as two of the members of this family, c‐rel and relb, are absolute requirements for synthesis of ifn‐γ (mowen and glimcher, 2004).

Figure 2. schematic of early t cell activation. the t cell encounters a dendritic cell (dc) bearing its cognate peptide in an mhc molecule, and binds the peptide mhc though cd3 and cd4 or 8. subsequently, co stimulation occurs through dc bound cd86, cd80, ox40l and 4 1bbl. this induces full activation and effector function in the t cell.
