Abstract
CD137 has long been recognized as a
costimulatory receptor for growth and
functional maturation of recently activated
T cells in the presence of T-cell
receptor signal. In this report, we present
the fact that, in the absence of MHC and
antigen, triggering of CD137 by an agonist
monoclonal antibody induces vigorous
growth of both CD8 and CD4 T
cells with memory phenotype, whereas it
does not affect naive T cells. Moreover, T
cells with memory phenotype accumulate
progressively in transgenic mice overexpressing
CD137 ligand. CD137-mediated
proliferation of memory T cells is directly
through CD137 on T cells and does not
require IL-15 and IFN-. Our results de-
fine a new role of CD137 signal in the
growth of memory T cells. (
