The cellular requirements for immune response (Ir) gene expression in a T cell proliferative response under dual Ir gene control were examined with radiation-induced bone marrow chimeras. The response to poly(Glu55Lys36Phe9)n (GLphi) requires two responder alleles that in the [B10.A X B10.A(18R)]F1 map in I-Ab and I-Ek/Cd. Chimeras in which a mixture of the nonresponder B10.A parental cells (wh...
The role of H-2-linked genes in helper T-cell function. VI. Expression of Ir genes by helper T cells
We examined the expression of (TG)-A--L specific Ir genes in helper T cells using T cells from low responder leads to (B10, high responder x low responder) F1 chimeric mice. In this paper, the low responder strain studied was B10.M, H-2f. B10.M T cells from these chimeric animals do not help anti-TNP-(TG)-A--L responses, even though they have matured in a high responder thymus and been primed ...
The genetic control of the antibody response to a synthetic polypeptide antigen designated poly-L(Tyr, Glu)-poly-D,L-Ala--poly-L-Lys [(T, G)-A--L] has been studied in congenic high responder C3H.SW (H-2(b)) and low responder C3H/HeJ (H-2(k)) strains of mice. This response is controlled by the Ir-1 gene and is H-2 linked. The method employed was to study the ability of specifically primed or "ed...
We studied the genetic restrictions on the interaction between T cells, B cells, and antigen-presenting cells (APC) involved in the H-2-linked Ir gene control of the in vitro secondary antibody response to sperm whale myoglobin (Mb) in mice. The B cells in this study were specific for Mb itself, rather than for a hapten unrelated to the Ir gene control, as in many previous studies. Low responde...
A rabbit antiidiotypic antiserum raised against an A.SW IgG1K monoclonal anti-sperm whale myoglobin (Mb) antibody, HAL19, and extensively absorbed with normal mouse immunoglobulin and MOPC 21 (IgG1K), was found to detect a common or major anti-Mb idiotype expressed by some but not all anti-Mb monoclonal antibodies, regardless of immunoglobulin G (IgG) subclass, and by 40-50% of the anti-Mb anti...
The inheritance of B-cell responsiveness to lipopolysaccharide (LPS) was studied in 55 crosses between mice of the low-responder strain C3H/HeJ and the high-responder strains B10.5M and C3H/Tif. F1 hybrid mice between the low-and the high-responder strains, showed in every case responses which were intermediate between the responses obtained with each parent. The responsiveness among F2 hybrid ...
In vitro lymphocyte responses of high responder (HR) and low responder (LR) guinea pigs from pe-ripheral blood lymphocytes (PBL) to parasite antigens soluble protein third stage larvae (SPL3) and soluble protein adult stage ( SPA), non-parasite antigen ovalbumin (OVA) were examined. There was substantial differences between HR and LR guinea pigs in the rate of acquisition of responsiveness to t...
Elucidating the regulation of glucose-stimulated insulin secretion (GSIS) in pancreatic islet β cells is important for understanding and treating diabetes. MIN6 cells, a transformed β-cell line derived from a mouse insulinoma, retain GSIS and are a popular in vitro model for insulin secretion. However, in long-term culture, MIN6 cells' GSIS capacity is lost. We previously isolated a subclone, M...
