Considering the emerging importance of phenotypic markers as indicators of cell function
and differentiation, we studied patterns ofCD44 and CD45RB expression in CD8+ murine T
cells with prior exposure to antigen or staphylococcal enterotoxin B ( SEB ). Following in
vivo priming with two purified protein derivatives (one from a virulent WHO strain and the
other from an avirulent strain), T ...
