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.

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.

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.

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.

Receptors for concanavalin A cluster at the front of polarized neutrophils
Nature, 1980Polymorphonuclear neutrophils (PMN) can recognize, engulf and kill microorganisms and are thus an important host defence against infection. The initial encounter between a microbe and the neutrophil takes place at the neutrophil surface. Receptors, including those for the Fc end of the immunoglobulin G (ref.

Concanavalin a Binding Receptors on Trypanosoma cruzi Amastigotes
The Journal of Parasitology, 1980501-505) as adapted by Garcia et al. (1978, Arch. Biochem. Biophys. 188: 315-322). The bugs used in our experiments consumed 160 to 200 mg of blood. Only 15% of the insects did not feed fully and were discarded. The number of bugs dissected at different intervals after infection and the number of parasites per bug are summarized in Table I.

Modulation of NMDA Receptor Subunits Expression by Concanavalin A
Neurochemical Research, 2016The processes of N-methyl-D-aspartate (NMDA) receptor subunits expression were examined in cortical neurons and rat brain in order to investigate how the concanavalin A (Con A) modulates neuronal cells. Con A modulated the expression of NMDA receptor subunits in cultured cortical cells.

Mitogenic stimulation and the redistribution of concanavalin A receptors on lymphocytes
Experimental Cell Research, 1981Abstract When mouse spleen (Ig − ) cells undergo maximal mitogenic stimulation by optimal concentrations of concanavalin A (conA), the Ig − cells form caps of conA very slowly, with 50% of maximum cap formation occurring after about 10 h and maximal capping after about 24 h.
