Research Abstract |
In brain microglia, alpha 7 nicotinic receptor activation induced calcium release from intracellular calcium stores through tyrosine-kinase-dependent metabotropic pathways. This calcium response was enhanced under acidic condition or oxidative stress and thereby suppressed lipopolysaccharide(LPS)-induced production of inflammatory cytokines. LPS stimulation also promotes long survival and protective function such as phagocytosis in microglia. Since alpha 7 nicotinic receptors play a role in facilitating protective function in microglia, this receptor subtype may be a potential target for brain inflammatory diseases.
