The rotavirus nonstructural glycoprotein, NSP4, has been identified as the first viral enterotoxin capable of inducing diarrhea. To investigate the biological function of NSP4 in the inflammatory process, a cDNA from human rotavirus (Wa strain) RNA segment 10 was amplified by RT-PCR, cloned into TA vector, and subsequently subcloned into pET23b expression plasmid. The expression of NSP4 protein was determined by SDS-PAGE and Western blotting, then, the protein was purified by affinity chromatography on Ni-NTA-agarose column. The inflammatory effects of NSP4, namely, production of nitric oxide (NO), pro-inflammatory cytokines (IL-1β, IL-6, IL-10, and TNF-α), and prostaglandin E2 (PGE<SUB>2</SUB>), was evaluated using NSP4-stimulated RAW 264.7 murine macrophages and compared with those observed after stimulation with lipopolysaccharide (LPS). The levels of IL-1β, IL-6, and TNF-α were significantly increased, and those of NO and PGE<SUB>2</SUB> also increased in NSP4-stimulated RAW 264.7 cells. These findings indicate that NSP4 plays an important role in the inflammatory response observed during rotavirus infection.
