Isolation on discontinuous gradients of bovine albumin of a subpopulation of human lymphocytes exhibiting precursor characteristics. 1975

J G Gatien, and E E Schneeberger, and R Parkman, and E Merler

Purified subpopulations of lymphocytes were obtained from discontinuous bovine serum albumin (BSA) gradients and by rosetting sheep erythrocytes (E) or EAC1-3. Cells from layers 1 to 3 of the BSA gradient which failed to rosette with E were highly reactive with EAC1-3 and with anti-human IgM. Demonstrating a high spontaneous rate of DNA synthesis and primitive morphology, these cells responded to pokeweed mitogen, concanavalin A and alloantigens, but not to phytohemagglutinin or soluble antigens. Constituting from 0.5% to 3.0% of all lymphocytes from each of the tissues studied, these lymphocytes appear to represent an earlier stage in human lymphocyte development distinct from both T and B cells.

UI MeSH Term Description Entries
D007104 Immune Adherence Reaction A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.

D007111 Immunity, Cellular Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007959 Lymphocyte Culture Test, Mixed Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D011947 Receptors, Antigen, B-Cell IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
