A facilitatory effect of bicuculline on the enteric neurones in the guinea-pig isolated colon.

abstract：BACKGROUND AND PURPOSE:Toll-like receptor 4 (TLR4) plays a key role in the induction of inflammatory responses both in peripheral organs and the CNS. Curcumin exerts anti-inflammatory functions by interfering with LPS-induced dimerization of TLR4-myeloid differentiation protein-2 (MD-2) complex and suppressing pro-infl...
