The lectin binding sites on the plasma membrane components of human lymphoblastoid cell lines. 1979

L G Gürtler, and B Sramota, and H Cleve

The plasma membrane components of five human B-cell lines and three human T-cell lines were separated by dodecyl sulfate polyacrylamide gel electrophoresis, incubated with the radioactive labeled lectins from lentil, castor bean, wheat germ, Phaseolus bean, peanut, gorse and the Roman snail and the molecular weights of the binding sites determined. The lentil, castor bean and wheat germ lectin bound to multiple components from molecular weights (Mr) 20 000 to 200 000 within the plasma membranes, whereas peanut lectin bound preferentially to glycoproteins of Mr 150 000 and 83 000 in B-cells, and 150 000 and 130 000 in T-cells. The gorse lectin bound to a 220 000 component in B-cells which was not labeled in T-cells.

D001402 B-Lymphocytes Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.

D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species. Species Specificities,Specificities, Species,Specificity, Species
D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D037102 Lectins Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
