Cytoskeletal control of concanavalin A receptor mobility in peritoneal macrophages

Experimental Cell Research, 1979
Abstract The role of microtubules and microfilaments in controlling the mobility of concanavalin A (ConA) receptors in the membrane of peritoneal macrophages was examined. Receptor mobility was assessed by counting the number of cells exhibiting cap formation following incubation with fluorescein-labelled ConA for 5 min at 37 °C.

The distribution of concanavalin a receptor sites on the membrane of chromaffin granules

Journal of Cell Science, 1975
ABSTRACT The distribution of concanavalin A (con A) receptor sites on the membranes of chromaffin granules has been investigated by binding studies using 125I-labelled con A and by electron-microscope studies using ferritin-labelled con A.

Are Concanavalin A Receptor Sites Mediators of Cell-Cell Adhesion?

Nature New Biology, 1973
THE identity of the chemical sites that mediate adhesions between tissue cells remains to be established. Attractive candidates for this role include carbohydrate-containing groups which have in recent years been shown to be common structural constituents of animal cell membranes1.

Immobilization of concanavalin A receptors during differentiation of neuroblastoma cells

Nature, 1981
Neuroblastoma cells serve as a useful model of neuronal development because compounds such as dimethyl sulphoxide (DMSO) and dibutyryl cyclic AMP cause them to undergo a process of controlled differentiation in tissue culture, during which they can extend long processes, develop characteristic excitability mechanisms, synthesize neurotransmitters and ...

Isolation of a concanavalin A receptor from mouse L cells

Biochemistry, 1975
A cell surface glycoprotein receptor for concanavalin A (Con A) has been isolated from mouse L cells. The isolation procedure involved dissolving whole L cells in 0.3 M lithium diiodosalicylate and extracting with aqueous phenol. The Con A receptor, which was found in the aqueous phase of this extract, was further purified by affinity chromatography on

Dynamic state of concanavalin a receptor interactions on fibroblast surfaces

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1975
Cultured normal and transformed fibroblasts were treated "in situ" by the concanavalin A-peroxidase labelling technique. It is known that peroxidase recognizes only a fraction of the bound lectin depending on the cell type. Kinetics studies revealed that 80 to 95 percent of the peroxidase and only 10 percent of the lectin are released from the cell ...

Interaction between the hepatic growth hormone receptor and concanavalin A

Molecular and Cellular Endocrinology, 1979
The interaction between the plant lectin concanavalin A (Con A) and hepatic receptors for human growth hormone (GH) has been studied in particulate and soluble microsomal membrane preparations from rabbit and rat liver. Con A shows a dose-dependent, partial (30%) inhibition of 125I-human GH binding which is reversed by the Con A competitor, alpha ...

CONCANAVALIN A SURFACE RECEPTORS AND CYTOPLASMIC ACTIN IN CELL ADHESION

Australian Journal of Experimental Biology and Medical Science, 1979
SummaryA double immunofluorescence staining technique to locate concanavalin A (Con A) surface receptors and cytoplasmic actin in the same cell was applied to monolayer cultures of rat foetal fibroblasts during cell detachment induced by trypsin and during cell attachment to a glass substratum.

EGF receptor‐mediated signals are differentially modulated by concanavalin A

Journal of Cellular Physiology, 1995
AbstractNIH 3T3 cells expressing hgh levels of the human epidermal growth factor (EGF) receptor were used to examine the effects of the lectin concanavalin A (Con A) on EGF‐mediated signaling events. Proliferation of NIH 3T3 cells expressing high levels of the human EGF receptor was inhibited in a dose‐dependent manner by Con A. At the same time, Con A

DYNAMIC BEHAVIOUR OF CONCANAVALIN RECEPTOR SITES ON RAT LYMPHOCYTES

1976
Publisher Summary This chapter provides an overview of the dynamic behavior of concanavalin receptor sites on rat lymphocytes. Studies on the binding of concanavalin A (Con A) to rat lymphocytes have revealed that these cells exhibit several million Con A binding sites on their surface.
