Notes:
Neonatal infection of C57BL/10 mice with cloned ecotropic and/or dual-tropic mink cell focus-inducing (MCF) mouse leukaemia viruses (MuLV), induces a wide spectrum of different lymphomas of T, B, and non-T/non-B cell types. The H-2 complex has a marked influence on both the development of lymphoma incidence and lymphoma type. A study using the oncogenic MCF 1233 virus and a series of B10 congenic mice enabled the mapping of the following:(a) Resistance to the early development of T cell lymphomas is controlled by the H-21-A locus.(b) Susceptibility to early T cell lymphomagenesis is associated with an I-A-regulated low anti-MCF 1233 envelope antibody response and persistent infection of the thymus.(c) B10 (H-2b) mice, which are resistant to early T cell lymphomagenesis induced by MCF 1233 or other MuLV isolates, have high anti-MuLV envelope antibody responses which are I-A-regulated. These mice develop more B cell lymphomas late in life in contrast to the early development of T cell lymphoma in B10.A (H-2a mice. The possible response mechanisms which underlie these observations, including: (1) I-A -regulated immunoselection against MuLV antigens expressed by (pre) leukaemic T cells, (2) aberrant expression of class II MHC antigens on some B cell lymphomas and (3) I-A-regulated chronic immunostimulation of MuLV-expressing (pre) leukaemic B cells, are discussed.
