monoclonal antibodies to cd3 ( or the alpha beta-chain t-cell receptor ) blocked cloned t-cell responses to the schizont extract , and although the responses of the majority of the cd4+ or cd8+ t-cell clones were restricted by autologous accessory cells and inhibited by monoclonal antibodies to either cd4 or cd8 , other clones responded to p. falciparum in the absence of accessory cells and were not regulated by the same monoclonal antibodies .
