Webb16 mars 2024 · During T-cell development, the TCR loci are rearranged; most cells will eventually become a TCRαβ + T cell; and in mice, the point of β-selection is at the DN3 stage. At this point, the progenitors need to have rearranged the Trb locus in a way that produces a functional β-chain; otherwise, the progenitor cannot progress in its … WebbRegulatory T cells. Regulatory T (T reg) cells (suppressor T cells) are essential for the maintenance of immune tolerance. Their main role is to stop T cell-mediated immune response at the end of an immune reaction. A second major task is to suppress auto-reactive T cells that escaped the process of negative selection in the thymus.
