UNLABELLED BACKGROUND Human and canine leishmaniasis (CanL) by Leishmania infantum is endemic in Italy, with a high percentage of infected asymptomatic animals. However, the immune response mechanisms underlying the clinical presentation of CanL have not been fully investigated. Among leishmanicidal molecules produced by activated macrophages, nitric(More)
Resveratrol, a polyphenol abundantly found in grapes and red wine, exhibits beneficial health effects due to its anti-inflammatory properties. In the present study, we evaluated the effect of resveratrol on inflammatory responses induced by lipopolysaccharide (LPS) treatment of human intestinal Caco-2 and SW480 cell lines. In the LPS-treated intestinal(More)
In this work, we examine the effects of lipopolysaccharide (LPS) treatment on nerve cells of chick embryo used as a universal avian model. We demonstrate that LPS leads to a dramatic cell loss in primary cultures of both glia and neurons, isolated from chick embryos. Toxic effects appear to be mediated by the Toll-like receptor (TLR)-4 complex, expressed in(More)
