ABSTRACT
The role of σB in Listeria monocytogenes infection of human intestinal epithelial cells was investigated. Invasion defects associated with loss of σB paralleled those of a ΔinlA strain independently of the σB-dependent P2
prfA
promoter. Concomitantly, amounts of inlA transcript and InlA protein were significantly decreased in the ΔsigB strain.
A fungal immunomodulatory protein Ling Zhi-8 (LZ-8) isolated from Ganoderma lucidum (GL) regulates immune cells and inhibits tumor growth; however, the role of LZ-8 in intestinal epithelial cells (IECs) is...
