Inhibition of Toll-Like Receptor 3-4 with Ethanolic Extract of Propolis on Innate Immunity in Diabetes Mellitus Mice (Mus musculus)

摘要

One of the most significant problems today is to treat the effects of metabolic diseases, such as diabetes. Thus, this study evaluated the ability of an ethanolic extract of propolis (EEP) to reduce inflammation in diabetes treatment. The used mice with STZ-induced diabetes mellitus (SID) and the expression of Toll-Like Receptor 3-4 was analyzed in their innate immunity cells. The SID mice had a higher TLR 3-4 expression compared with the healthy control group. Treatment of EEP in SID using three different doses significantly decreased the number of B cells with TLR 3-4 expression. This suggesting that EEP treatment decreases TLR3 & TLR4 expression on innate immunity (especially B cells) from over expression in SID which can affect the acute inflammatory and aggravate the diabetes condition. Even relatively low doses of propolis extract can decrease TLR3 and TLR4 expressed by B cell.
