H-2 congenic mouse strains were tested in vitro to investigate the genetic control of cell-mediated lympholysis (CML). Combinations were selected such that differences in various segments of H-2 could be examined for their ability to stimulate production of effector cells and to serve as targets for lysis. Particular emphasis was directed towards understanding the roles of LD and SD. SD-region differences are important in the sensitization of effector cells and they also function as strong targets for lysis, or as markers for the CML targets. LD differences are also important for sensitization of cytotoxic effector cells, but they serve only as very weak targets for lysis. Collaboration occurs between LD and SD in generation of CML. The nature of this interaction can be of two types: together LD and SD can produce CML which neither difference alone can stimulate; LD can enhance a CML response stimulated by SD-region differences alone.

Cytotoxic Effector

Cell-mediated lympholysis (CML) to trinitrophenyl (TNP)-modified autologous splenic lymphocytes has been recently reported in the mouse (1). Both the sensitization and effector phases of this phenomenon were shown to be T-cell mediated. Effector cell specificity studies indicated that modification of the target cells is a necessary but insufficient requirement for cytolysis, and suggested that altered cell surface components controlled by genes mapping in the mouse major histocompatibility H-2 complex (MHC) are important in the specificity of the cytotoxic reaction (1). In allogeneic models the generation of cytotoxic effector cells has been shown to be preceded or accompanied by immunogen- induced proliferation of responding lymphocytes, i.e. a mixed lymphocyte reaction (MLR) (2-5), although the generation of effectors may not necessarily always be the consequence of extensive cell proliferation (5). If the induction of cytotoxic effector lymphocytes by modified syngeneic spleen cells is characteristic of sensitization with cellular alloantigens, one would expect to find that sensitization with TNP-modified autologous cells would also induce thymidine incorporation by the responding cells in the culture. The present report demonstrates that both stimulation of thymidine incorporation and generation of cytotoxic effector cells are part of the in vitro response to TNP-modified autologous lymphocytes. However, the MLR to TNP- modified autologous cells consistently appeared to be less pronounced when compared with an allogeneic MLR, whereas the cytotoxic activity of the effector cells generated by sensitization against TNP-modified autologous cells was frequently as high as that detected against H-2 alloantigens. These two components of reactivity to modified self are verified in several C57BL/10 congenic and B10.A recombinant mouse strains.

Congenic mouse strains differing only at genes within the H-2 complex were found to have virus-specific cytotoxic effector cells in their spleens during or after recovery from Friend leukemia virus-induced splenomegaly. These effector cells were theta-positive T lymphocytes which functioned in vitro without help or inhibition by B lymphocytes or glass-adherent cells. The antigenic specificities recognized by the effector cells were viral-induced cellular antigens apparently different from those identified by serological techniques.

Primed Mouse

Monolayers formed of normal mouse spleen cells attached to polystyrene coated with poly-L-lysine were tested for their ability to bind specifically antigen-reactive cells in normal or primed mouse spleen. 88 to greater than 98% of the activity of cytotoxic populations was removed by a single adsorption. However, normal spleen cells or spleen cells previously primed in vitro could not be depleted of their capacity to be sensitized, even when adsorption effectively removed all residual cytotoxic activity from the same previously primed population. In fact, exposure to an immunoadsorbent augmented the ultimate cytotoxicity generated in a nonspecific fashion. This augmentation was especially dramatic in the case of a previously primed population and may have reflected the removal of a nonspecific suppressor. If antigen-reactive precursors cannot be removed efficiently by adsorption, other approaches to the generation of tolerant lymphoid populations, such as specific suppression of precursor differentiation must be sought.

Cytotoxic Effector

The specificity of C57BL/10 cytotoxic effector cells generated by in vitro sensitization with autologous spleen cells modified with a series of related nitrophenyl compounds was investigated. The failure of trinitrophenyl (TNP)-sensitized effector cells to lyse TNP-beta-alanylglycylglycyl(AGG)-modified target cells is presented as evidence contradicting the intimacy or dual receptor model or T-cell recognition in its simplest form. Data are also shown indicating that sensitization with N-(3-nitro-4-hydroxy-5-iodophenylacetyl)-AGG-modified stimulating cells generates noncross-reacting clones of cytotoxic effector cells.

A fragment of the human gene for c-erb-B was used to map homologous sequences in mice. Analysis of somatic cell hybrids and recombinant inbred and congenic mouse strains indicated that this gene, designated Erbb, is closely linked to the gene for alpha-globin on mouse chromosome 11. Several genes controlling hematopoietic differentiation map to mouse chromosome 11.
