HAPTEN-SPECIFIC IgE ANTIBODY RESPONSES IN MICE
The present studies have established conditions for the demonstration of cooperative interactions between specific T and B lymphocyte populations in the development of IgE antibody responses in vivo in mice. This has been accomplished by utilizing a system which permits the successful adoptive transfer to irradiated recipients of DNP-specific secondary IgE responses with spleen cells from suita...
متن کاملCarrier Function in Anti-hapten Antibody Responses
The studies reported here demonstrate that immunocompetent lymphoid cells from allogeneic donor guinea pigs stimulate the synthesis of anti-DNP and anti-OVA antibodies by recipients previously primed with DNP-OVA. This allogeneic effect occurs spontaneously in the absence of any further anti-genic challenge. Furthermore, the transfer of allogeneic cells prepares DNP-OVA-primed recipients for a ...
متن کاملT and B cell in hapten-specific carrier-determined tolerance
BDF1 mice were made tolerant by a single i.v. injection of 1 mg of DNAP-gamma1 or by weekly i.v. injections of 0.2 mg of DNP-gamma1 given for a month. In both instances, spleen cells of tolerant animals were fractionated to obtain pure populations of T cells (nonimmunoglobulin-bearing cells), referred to as tolerant T cells, and B cells (immunoglobulin-bearing cells) referred to as tolerant B c...
متن کاملEpitope-specific regulation. I. Carrier-specific induction of suppression for IgG anti-hapten antibody responses
The epitope-specific regulatory system selectively controls IgG antibody production to the individual (haptenic) determinants on a complex antigen. This system can be specifically induced to suppress primary and secondary IgG antibody responses to dinitrophenyl hapten (DNP) without interfering with antibody responses to epitopes on the carrier molecule on which the DNP is presented. Furthermore...
متن کاملExtrinsic Cotton effects in hapten--carrier and hapten--antibody interactions.
Two homogeneous univalent hapten-protein conjugates, prepared by the covalent attachment of a single 2,4-dinitrophenyl (DNP-) or 2,4,6-trinitrophenyl (TNP-) side chain to the cysteine-SH in the active site of the enzyme papain, have been found to exhibit large Cotton effects in the wavelength region of the absorption bands of the DNP or TNP groups. This indicates that the DNP or TNP groups are ...
