In vivo or in vitro treatments with anti-I-J alloantisera abolish immunity to AKR leukemia
1980
Abstract
This paper provides evidence for the involvement of immune mechanisms in conferring resistance to a spontaneous AKR leukemia. It is shown that genes in the B, J, or E subregions of the H-2 complex confer resistance to a spontaneously arisen, tissue culture-adapted AKR thymoma, BW5147. A direct correlation is demonstrated between survival to injected BW5147 cells and humoral responsiveness in various hybrids obtained from crosses of AKR mice and C57BL/10 or C3H/DiSn derived congeneic strains differing at H-2. Cellular immunity appears to play no role in resistance to the proliferation of tumor cells. It is further established that development of effective humoral immunity depends on B cells and Ly-1+, 2-, 3- helper T-cells bearing the I-Jk phenotype. These findings seem directly applicable to the spontaneous disease, and results of studies using transformed cells from an overtly leukemic AKR mouse parallel those obtained using BW1547 cells.
