RECEPTORS ON IMMUNOCOMPETENT CELLS

Receptors on Immunocompetent Cells

During the course of the immune response to dinitrophenylated guinea pig albumin (DNP-GPA), a striking and parallel increase in avidity for epsilon-DNP-L-lysine occurs in the receptors on antigen-binding lymphocytes, antibody secreted by individual plaque-forming cells, and serum antibody molecules. A detailed analysis of the avidity distribution of antibody produced by plaque-forming cells ind...

Differences of IL-1β Receptors Expression by Immunocompetent Cells Subsets in Rheumatoid Arthritis

IL-1β is involved in the induction and maintenance of chronic inflammation in rheumatoid arthritis (RA). Its activity is regulated and induced by soluble and membrane-bound receptors, respectively. The effectiveness of the cytokine depends not only on the percentage of receptor-positive cells in an immunocompetent subset but also on the density of receptor expression. The objective of this stud...

Surface Antigens of Immunocompetent Cells

The effect of preincubation with anti-theta or anti-mouse immunoglobulin (Ig) and complement (C') on immune responsiveness of spleen cells from BALB/c mice immunized with sheep erythrocytes (SE) was investigated. Both treatments greatly depressed the remaining ability to produce a secondary response to SE in vitro. Normal BALB/c spleen cells were far less effective in reconstituting the respons...

Immunocompetent Cells of the Chicken

Specific antisera to chicken thymus and to bursa of Fabricius were obtained in rabbits. After appropriate absorption and dilution all four anti-thymus sera, in the presence of guinea pig C', killed >90% of thymus and <==12% of bursa cells. They were cytotoxic for approximately 50% of spleen cells and did not affect antibody-forming cells. The surface antigen detected by these antisera was named...
