Actin co-caps with concanavalin A receptors
Nature, 1977PREVIOUS studies have given mainly indirect1,2, and some direct3,4 evidence that the mobility of surface membrane receptors may be controlled by cytoplasmic microfilaments and microtubules. It has been proposed1,2 that the receptor–cytoskeletal complex may have important roles in cell–cell recognition, cell motility and cell division. This study, using

Synthetic concanavalin A receptors and erythrocyte agglutination
Nature, 1978THERE is considerable evidence to suggest the involvement of cell surface carbohydrates in cell-cell recognition and adhesion in, for example, muscle cell fusion1 and the adherence of bacteria to cells2. It is not yet clear whether the selectivity of the recognition process is a consequence of the structure and sequence of the saccharide chain and/or ...

Mobility of Concanavalin a Receptors in Trypanosoma cruzi
The Journal of Parasitology, 1980Furthermore, capping was inhibited when 0.2 M a-D-manoside was present in the system. When 250 ,/g/ml of FITC-Con A was incubated with the amastigotes at 4 C for 60 min, the amastigotes were agglutinated and showed a diffuse surface fluorescence. This pattern did not change when the temperature was raised to 37 C, indicating that the mobility of ...

Relationship of prolactin receptors to concanavalin A binding
Biochimica et Biophysica Acta (BBA) - General Subjects, 1979Concanavalin A, which binds to specific carbohydrate determinants on the cell surface, was used to investigate the binding of prolactin to its receptors in liver membranes from female rats. The binding of 125I-labeled ovine prolactin to receptors was sharply inhibited by concanavalin A.

Developmental restriction of mobility of concanavalin a receptors
Journal of Cellular Physiology, 1982AbstractTrypsinized cells from embryonic chick neural retina redistributed concanavalin A receptors to patches and caps. Between 12 and 16 days of development, the ability to redistribute concanavalin A receptors declined. This restriction in mobility of the receptors was accompanied by changes in susceptibility to the capping‐inhibitory drugs ...

Restriction of receptor mobility and the agglutination of cells by concanavalin a
Experimental Cell Research, 1975Summary Transformed hamster fibroblasts with a high ATP content which are not agglutinated by concanavalin A (ConA) can be induced to agglutinate by decreasing their ATP content, mixing of glutaraldehyde prefixed ConA-coated cells with unfixed uncoated cells, or mixing of unfixed ConA-saturated cells with uncoated cells.

The effects of concanavalin a on the mobility of lymphocyte surface receptors
Experimental Cell Research, 1973Abstract It has been found that concanavalin A (Con A) bound to the lymphocyte surface can either induce cap formation or inhibit cap formation of various receptors including those for Con A itself. The expression of these antagonistic activities is highly dependent on the conditions under which cells are incubated with Con A.

Interaction of concanavalin A with lactogenic receptors in isolated membranes
Archives of Biochemistry and Biophysics, 1982Abstract Specific binding of lactogenic hormones to their receptors in membranes from lactating mouse liver is inhibited by concanavalin A (Con A). Binding to solubilized receptors is not affected by the presence of Con A in the binding reaction. However, these solubilized binding proteins are retained on Con A-Sepharose columns.

Concanavalin A receptors and capping in control and activated macrophages
The Histochemical Journal, 1983Macrophages activated in vivo with Corynebacterium parvum and asbestos showed an increased sub-population of cells which capped spontaneously on incubation with fluoresceinated Concanavalin A compared to saline-induced control macrophages. This capping was unaffected by colchicine but was inhibited by cytochalasin B.

Evidence for concanavalin a-receptors and their redistribution on lumbricid leukocytes
Developmental & Comparative Immunology, 1978Abstract Fluorescent and radioactive concanavalin A (Con A) were used to demonstrate the existence of Con A-receptors on earthworm leukocyte membranes. Inhibition of binding by methyl-α- d -mannose, methyl-α- d - glucose and d -fructose suggested that Con A can bind to specific sites.
