Abstract
- This paper investigates major histocompatibility complex (MHC) regulation of the class of the immune response given in vitro and in vivo following immunization of the congenic BALB/k (H-2<superscript>k</superscript>) and BALB/c (H-2<superscript>d</superscript>) mice with the hapten trinitrophenyl (TNP). TNP-immune lymph node cells from BALB/k mice produced high levels of interferon-γ (IFN-γ), interleukin-5 (IL-5) and IL-2 when stimulated with TNP-antigen-presenting cells (APC) in vitro, while TNP-immune lymph node cells from BALB/c mice produced very low levels of these cytokines. No significant difference was found in antigen-specific production of IL-3, IL-4 and tumour necrosis factor-α (TNF-α). There was a strong correlation between the pattern of cytokine production in vitro and the secondary antibody production in vivo. Sera from BALB/k mice had anti-TNP IgG2a, IgG2b and IgG3 levels threefold greater, and anti-TNP IgA levels eightfold greater, than BALB/c mice. The level of specific IgG1 and IgE was only marginally raised in BALB/k mice. In contrast to these strain differences in cytokine and antibody production, there was no difference in two measures of cellular immunity: contact sensitivity in vivo and antigen-specific lymphocyte response in vitro. Our results suggest that there is a good correlation between the production of cytokines in vitro and antibody response in vivo, but not with measures of cellular immunity. Moreover, this MHC control of the class of the immune response to TNP does not fit into the T-helper type-1 (Th1)-Th2 paradigm. [ABSTRACT FROM AUTHOR]
