Idiotype-specific T lymphocytes. II. capability of generation of idiotype-specific T lymphocytes is determined by corresponding VH gene
H Yamamoto, S Bitoh and S Fujimoto
MOPC-104E (M104E) idiotype-specific and major histocompatibility
complex-restricted T lymphocyte activities were investigated in BALB/c
(Igh-1a) and its Igh-1-congenic strains of mice, such as C.AL-20 (Igh- 1d),
BAB-14 (Igh-1b), and CB-20 (Igh-1b). Idiotype-specific T lymphocytes could
be induced in BALB/c and BAB-14 by immunization of viable M104E tumor cells
followed by surgical removal and in vitro restimulation with the homologous
tumor cells. On the other hand, C.AL- 20 and CB-20 mice did not show the
idiotype-recognizing capacity even though they could mount comparable
cytotoxic T lymphocyte activities against M104E to BALB/c and BAB-14. The
results strongly suggest that the inducibility of M104E cross-reactive
idiotypy closely paralleled the producibility of corresponding
idiotype-specific T lymphocytes. Genetically defined VH gene products might
act as internal images that construct idiotype network systems.
