Suppression of immunoglobulin G synthesis as a result of antibody-mediated suppression of immunoglobulin M synthesis in chickens.
Development of heterogeneity of immunoglobulin classes has been investigated in the chicken by studying the effects of antibody-mediated suppression of IgM synthesis. Treatment of 13-day embryos with purified goat antibodies to IgM resulted in the elimination of IgM-containing cells from the bursa of Fabricius of 16- and 19-day embryos. When combined with bursectomy at hatching, administration ...
متن کاملSuppression of in vitro antibody synthesis by immunoglobulin-binding factor
Alloantigen-activated mouse T cells secrete a factor which binds to the Fc fragment of IgG and blocks complement (C) activation by IgG (immunoglobulin-binding factor, IBF). IBF was found to suppress the direct plaque-forming cell (PFC) response of mouse spleen cell cultures to sheep erythrocytes and to dinitrophenylated aminoethyldextran (T-independent antigen). Purification of IBF by affinit...
متن کاملSuppression of Immunoglobulin Class Synthesis in Mice
Germfree BALB/c mice have been treated from birth with intraperitoneal injections of purified goat antibodies to mouse IgM. The treated mice, and controls which had received an equivalent amount of goat gamma-globulin, were sacrificed at 8 or 13 wk of age. Compared to controls, mice given anti-micro (a) had very few germinal centers in spleen and lymph node, (b) had decreased numbers of mature ...
متن کاملActive Suppression of Immunoglobulin Allotype Synthesis
Long-term (chronic) allotype suppression, previously reported only in rabbits, is shown here to occur in at least one strain combination of mice as well. Close to 50% of the offspring of SJL (Ig(b)) males mated to BALB/c (Ig(a)) females immunized against the paternal allotype were found to be suppressed for Ig-1b (gammaG(2a)) at 6 months of age. These mice are called "chronically" suppressed. T...
