Abstract
Interleukin-1beta (IL-1beta) is an important proinflammatory cytokine that exert wide biological functions in the central nervous system (CNS). Voltage-gated Ca2+ channels in plasma membrane are essential components of Ca2+ signal whose change on pathological conditions is closely related to processes of diseases. Although both IL-1beta and Ca2+ channels have key roles in injury and disease of the brain, so far their relations have been reported in few studies. The effects of IL-1beta on Ca2+ channels in cultured cortical neurons of rats were investigated using patch-clamp recording in present research. Our results showed that both 10 and 50 ng/mL of IL-1beta treatment inhibit the Ca2+ currents in time and dose dependent manner, without the change of activation properties of voltage-gated Ca2+ channels (VGCC)s.
