pubmed:abstractText |
T-helper function was evaluated in mice genetically selected for high (H) or low (L) antibody (Ab) responsiveness to Salmonella flagellar antigen (Ag) (Selection III). In this Selection as opposed to what was demonstrated in Selections I, II and IVA, the interline difference was not proven to be based upon the modification of Ag processing and presentation at macrophage level. CD4+/CD8+ lymph node ratio is similar in HIII and LIII mice, both lines being equally susceptible to in vivo depletion of CD4+ T cells by GK 1-5 monoclonal antibody (mAb) treatment. Nevertheless, the Ab responsiveness of the two lines was differently modulated by GK 1-5 mAb: the inhibition of Ab responses to various Ag required lower mAb doses and was long lasting in LIII as compared to the transient effect of higher mAb doses observed in HIII. LIII mice were also refractory to Salmonella-induced reversion of GK 1-5 mAb inhibition. Moreover, in vitro specific I proliferation was constantly lower in LIII, though its IL-2 production was unexpectedly similar to that of HIII T cells. Results of in vivo and in vitro experiments are thus consistent with a defective response of T-helper cells to immunogenic challenge in LIII mice.
