Spleen cells from adult (BALB/c x AKR/J)F1 mice primed in vivo with fetal calf serum (FCS) can spontaneously generate anti-parental AKR/J cytotoxic T cells (CTL) in a 5-day in vitro culture containing 5% FCS. This response is distinguished by the following features: (i) it is anti-parental but not anti-self, and (ii) it has specificity for the Kk parental determinant as shown by mapping studies on a variety of targets and antiserum-blocking experiments. Although specifically elicited by FCS and mediated by FCS-induced T-helper cells, it is ascertained that this cytotoxicity is not directed against Kk components modified by absorbed FCS as shown by cold-target competition studies. Further experiments involved a comparative investigation of the patterns of lysis of allogenically induced CTL, FCS-induced CTL, and natural killer (NK) cytotoxic activities on tumor cell targets. The resistance of BW 5147 tumor targets to NK- and FCS-induced lysis was found to be dramatically overcome by treatment with mitomycin C, and provides circumstantial evidence for a functional relationship between the FCS-induced anti-parental CTL effectors and NK cells based on the observed similarity in lytic patterns of these two effector types. With reference to the work of other authors, the possibility that hybrid resistance and its possible in vitro counterpart, F1 anti-parental CTL cytotoxicity, and NK activity are mediated by similar or common effector mechanisms is discussed.
