Immune responses in vitro. XII. Two independently segregating loci control Mis product(s).

Distribution analyses of Misa in (BALB/c x DBA/2)F2 animals indicate that two independently segregating loci control the expression of Misa products. The results were dependent upon the use of x-irradiated cells a the antigen in MLR. The use of non-x-irradiated antigen in the MLR led to results that were uninterpretable because both DBA/2 and (BALB/c x DBA/2)F1 cells responded to x-irradiated BALB/c cells. Even though DBA/2 cells did not respond to (BALB/c x DBA/2)F1 cells, their reactivity to BALB/c cells indicates that the Misb of BALB/c is not null.

A new minor histocompatibility locus linked to H-3.

B10, BALB.B, and A.BY shared an allele at a new locus not shared by B10.LP-H-3b. This locus is linked to the minor histocompatibility gene, H-3, in the 5th linkage group of chromosome 2 of the mouse. The product of the new gene fits the criteria of a minor histocompatibility antigen, since it induced as well as served as a target for cytotoxic lymphocytes (CTL) and its presence accelerated skin graft rejection when compared with that caused by H-3.1. F1 complementation of skin graft rejection and generation of CTL indicated that A.BY and BALB.B do not share H-3a with B10 as previously reported but possess the c allele of their congenic partners A and BALB/c. Thus, B10.LP-H-3b and B10 differ from one another by at least 2 minor histocompatibility loci. The specificity of CTL developed in B10. LP-H-3b and appropriate F1 hybrids indicate that the lytic activity of CTL specific for H-3.1 was restricted to target cells possessing H-2Kb antigens; this contrasted to the H-2Db-restricted activity of CTL specific for the product of the new gene.

Immune responses in vitro. VI. Genetic control of the in vivo-in vitro discrepancies in 19S antibody synthesis.

The finding that the relationship of the in vitro and in vivo responses of different strains of mice is under genetic control indicates that at least two mechanisms must operate under in vivo conditions to control 19S antibody synthesis. One is involved in the termination of 19S antibody synthesis; the other has a regulatory role on the magnitude of the response. In light of these findings, various concepts based on other genetically controlled immune responses and on the limiting dilution technique should be reassessed. Furthermore, the suppressive in vivo mechanism may be an important type of control in the resistance or susceptibility to the establishment or maintainance of neoplasms.
