Aconitum kusnezoffii used as an analgesic and anti-inflammatory. It is often not only in Mongolian medicine but also traditional Chinese medicine. However, there are few studies on its impact of inflammatory cytokines. This study explored the effects vitro human colon cancer (Caco-2) cells. Cytotoxicity was assessed by measuring expression IL-1β, IL-6, IL-8, TNF-α enzyme-linked immunosorbent as...

BACKGROUND Various differentiation-inducing agents or harvesting of spontaneously late post-confluence cultures have been used to differentiate the human colon carcinoma Caco-2 cell line. We report a new procedure to generate pre-confluent subcultures of Caco-2 population at various stages of differentiation without altering culture conditions. MATERIALS AND METHODS Ultrastructural analysis, ...

BACKGROUND AND AIM Intestinal epithelial cells (IEC) are thought to participate in the mucosal defence against bacteria and in the regulation of mucosal tissue homeostasis. Reactivity of IEC to bacterial signals may depend on interactions with immunocompetent cells. To address the question of whether non-pathogenic bacteria modify the immune response of the intestinal epithelium, we co-cultivat...

BACKGROUND Physiological stressors may alter susceptibility of the host intestinal epithelium to infection by enteric pathogens. In the current study, cytotoxic effect, adhesion and invasion of Salmonella enterica serovar Typhimurium (S. Typhimurium) to Caco-2 cells exposed to thermal stress (41 degrees C, 1 h) was investigated. Probiotic bacteria have been shown to reduce interaction of pathog...

Norovirus (NV), a member of the family Caliciviridae, is one of the important causative agents of acute gastroenteritis. In the present study, we found that virus-like particles (VLPs) derived from genogroup II (GII) NV were bound to cell surface heparan sulfate proteoglycan. Interestingly, the VLPs derived from GII were more than ten times likelier to bind to cells than were those derived from...
