Cellular Requirements for the Primary in Vitro Antibody Response to Dnp-ficoll
نویسندگان
چکیده
The cellular requirements for the primary in vitro IgM and IgG response to dinitrophenyl-substituted Ficoll were examined. Neither thymus-derived lymphocytes nor macrophage-rich splenic adherent cells were required for anti-DNP antibody synthesis. DNP-Ficoll is therefore tentatively classified as a "thymic-independent" antigen.

Ontogeny of mouse lymphocyte function. II. Development of the ability to produce antibody is modulated by T lymphocytes
The relative functional maturity of neonatal mouse spleen T- and B-cell populations was assessed by comparing the ability to respond to the thymic-independent antigen, DNP-Ficoll, or thymic-dependent SRBC by producing antibody in vitro. Although mouse spleen cells responded to DNP-Ficoll at an earlier age than they responded to SRBC or TNP-SRBC, the reason for the lag in the T-dependent respons...
متن کاملIR gene regulation of the response to trinitrophenyl-polysaccharides. Two independent genes are required for antibody production
The primary in vitro antibody response to TNP-Ficoll was found to be under H-2-restricted Ir gene control. Strains B10(H-2b), B10.A(H-2a), and B10.S(9R) (H-2t4) were consistently low responders while strains D2.GD(H-2g2), B10.GD(H-2g2), and B10.S(H-2s) were high responders. The in vitro TNP-Ficoll response in congenic recombinant and F1 hybrid mice demonstrated the requirement for complementati...
متن کاملCellular and molecular requirements for X-linked, hapten-specific B- cell blockade in CBA/N mice
CBA/N mice, a mutant CBA subline, harbor an X-linked B-cell defect which prevents them from mounting immune responses to certain thymic-independent antigens such as pneumococcal polysaccharides and haptenated-Ficoll derivatives. These mice and the hybrid male progeny of CBA/N females are also exquisitely sensitive to a hapten-specific blockade of their otherwise adequate immune responses to thy...
متن کاملMonoclonal antibody characterization of a unique immune response control locus between H-2S and D
The primary in vitro antibody response to the type 2 antigen, trinitrophenyl (TNP)-Ficoll, is controlled by two complementing loci in the H-2 region of the mouse major histocompatibility complex (MHC). High responder alleles at both loci are necessary for a high responder phenotype. Previous studies mapped one locus of control to the I-A subregion. In this report we demonstrate by recombinant a...

Treatment of lymphocytes with inducers of interferon a (IFN-a) results in the production of corticotropin (ACTH) and endorphin-like activities. The pro-opiomelanocortinderived hormones ACTH and a-, (-, and y-endorphin and the structurally related hormones [Leu]and [Metlenkephalin were therefore tested for their effects on the in vitro antibody response ofmouse spleen cells. ACTH and a-endorphin...
