B-cell precursors specific to sheep erythrocytes. Estimation of frequency in a specific helper assay
نویسنده
چکیده
A sensitive, specific, and reproducible in vitro helper assay is described which is suited to limiting dilution analysis of murine B cells. 1 in about 3,000 syngeneic splenic B cells can be induced to form plaque-forming cells (PFC) to sheep erythrocytes in this system. The induction of PFC is absolutely dependent on antigen and specific helper T cells.

The role of T helper 9(Th9) against Infectious Diseases
Background and aims: Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi or parasites .The Th9 subset develops in response to combined signals from TGF-b and IL-4 among a cacophony of other cytokines in an extracellular milieu. T helper 9 (Th9) cells, as a novel CD4 T cell subset, seem to play a complex role in the outcome of specific immune responses. In thi...
متن کاملAntigen-specific T-helper cells stimulate H-2-compatible and H-2- incompatible B-cell blasts polyclonally
Lipopolysaccharide (LPS)-activated B-cell blasts from C57BL/6J nu/nu spleen cells develop into IgM-secreting clones after stimulation by antigen-specific T-helper cells of C57BL/6J origin. Although induction of help is antigen-dependent, help itself acts polyclonally. 1 of 1--3 B-cell blasts is restimulated in a homologous fashion by LPS, or in a heterologous fashion by sheep erythrocyte (SRC)-...
متن کاملMurine Peyer's patch T cell clones. Characterization of antigen- specific helper T cells for immunoglobulin A responses
We successfully cloned antigen-specific T cells from murine gut-associated lymphoreticular tissue, i.e., Peyer's patches, which are dependent upon T cell growth factor and independent of antigen for continuous growth. These clones exhibit helper activity for IgA responses to sheep erythrocytes (SRBC) and have been designated T helper (Th) A. Two broad categories of Th A clones have been maintai...
متن کاملHelper Cells Are Restr icted to Coopera te wi th B Cells Expressing the IgVH Pheno type of the Pr iming B Cells
The humoral immune response to heterologous erythrocytes requires the cooperation of B lymphocytes and helper T cells. The production of anti-sheep erythrocytes (SRBC) 1 IgG is almost wholly dependent on the activity of T help (reviewed in 1). Helper T cells that recognize the carrier portion of an immunogen have been known for some time (2). More recently evidence has accumulated that other he...
متن کاملA strategy for the production of human monoclonal antibodies reactive with lung tumor cell lines.
Epstein-Barr virus (EBV)-immortalized cell lines were established from lymphocytes derived from peripheral blood, draining lymph nodes, bone marrow aspirates, tumors, and pericardial effusions from lung cancer patients. Ten of these lines were cloned and screened against glutaraldehyde-fixed lung tumor cells for tumor-specific antibody production using an enzyme-linked immunosorbent assay. None...
