Overview

Concanavalin A (ConA) is a well-established model to induce autoimmune hepatitis (AIH) in mice. It mimics the pathological alterations that occur in human. Con canavalin is a lectin and T-cell mitogen that can activate immune responses.

Effects

Concanavalin A has a strong affinity to alpha-mannose in glycans of typical therapeutic monoclonal antibodies. It has a lot of antitumoral effects, especially over oxidative stress.

Concanavalin A (Con A) has been used in the development of sol-gel phase-reversible hydrogels for modulated insulin delivery. The enzyme acetylcholinesterase (AChE) and 2',3',cyclic nucleotide-3'-phosphohydrolase (CNPase) are localized predominantly in the neuronal cell bodies.

Actions

Concanavalin A is known to activate T cells and to cause liver injury and hepatitis, mediated in part by secretion of TNFα from macrophages. The drug did not increase alkaline phosphatase activity in articular chondrocyte cultures.

Treatment

Concanavalin A treatment was found to induce phosphorylation of essentially all of the RLC in wild-type cells, but RLC phosphorylated levels in MLCK-A-cells are unaffected by concanavalin. A treatment of SW1353 cells increased the amount of membrane-type-1 matrix metalloproteinase protein in the cell membranes.

Dosage Studied

Dose-response curves that were generated within several minutes and were highly reproducible in multiple wash/measure cycles provided adsorption coefficients that showed mannose to bind to concanavalin A. With increasing ketamine concentration (5 x 10(-5)-10(-3) mol l-1), the amplitude of glutamate potentials was reduced and dose- response curves for ionophoresis of L-glutamate were shifted to the right.
