Among them are CD29 (β1) integrin that include VLA-4 (CD49d/CD29) [13], [39] Similarly, T cell migration CD44 receptor is a glycoprotein ascribed for having a role in lymphocyte homing to sites of inflammation [40], [41] Furthermore, signals emanating from the cytokine receptor for IL-7 (CD127) are particularly critical for the generation and long-term maintenance of memory CD8 T cells [42] and are of interest in understanding T lymphocyte functions during infections. Here, CD8A is linked to infection.
