What is it about?
Although ELAGIGILTV-specific CD8+ T cells from different donors initially possessed a naive phenotype, after antigen-induced in vitro expansion two distinct phenotypes correlating with cell proliferation rate emerged in the different donors.

Why is it important?
Those cultures achieving fewer cumulative population doublings (CPDs) were cytotoxic and displayed a CD45RA+CCR7- phenotype. In contrast, cultures reaching higher CPDs were non-cytotoxic T cells with a CD45RA-CCR7- phenotype. The generation of larger numbers of ELAGIGILTV-specific CD8+ T cells correlates negatively with the acquisition of a CD45RA+CCR7- phenotype and cytotoxic capacity.
