Surface layer protein from Lactobacillus acidophilus NCFM inhibit intestinal pathogen-induced apoptosis in HT-29 cells

Intestinal pathogens have been proposed to adhere to epithelial cells and cause apoptosis. This study was to investigate the inhibitory effects of surface layer protein (SLP, 46kDa) from Lactobacillus acidophilus NCFM on Escherichia coli and Salmonella-induced apoptosis in HT-29 cells and the mechanism of the inhibition was also studied. The SLP could alleviate the chromatin condensation caused by intestinal pathogens as observed under...
