Abstract

Based on the findings of common project 29 years ago, the Scandinavian J. of Immunology accepted and published our paper entitled by “FcγR-Dependent Regulation of the Biosynthesis of Complement C3 by Murine Macrophages: the Modulatory Effect of IL-6” (Bajtay et al. in SJI 35:195–201, 1992). In this report we attempt to review the previous results and evaluate them with our current concepts on the interaction between the actors of adaptive and innate immunity. Let us first to summarize the basic results and consequences from the paper from 1992. Abstract from 1991–1992: The effect of murine IgG isotypes (myeloma proteins) on the gene expression and secretion of the third component of complement (C3) has been studied using the in monocytoid cell line P388D1 and oil-elicited mouse peritoneal macrophages. It is demonstrated that the binding of lgG2a and lgG2b but not IgGl and IgG3 isotypes augments the biosynthesis of C3 both in the presence and in the absence of the phorbol myristate acetate in the case of both cell types. The multifunctional cytokine inlerleukin-6 (IL-6) alone reveals no effect on the gene expression of C3, but facilitates the effectiveness of mouse IgG2a and IgG2b. Confirming the role of FcgRll, a strong up-regulation of gene expression and secretion of C3 was found when macrophages were co-cultured with the F(ab')2 fragment of the FcγRII-specific monoclonal antibody 2.4 G2.
