However, un-controlled

However, un-controlled inflammation is harmful to the host and eventually damages the niche involved Salmonella find protocol growth. AvrA plays a role opposite to that of the other known effectors by inhibiting the inflammatory responses in intestine. Hence, one could argue that AvrA’s role in inhibiting inflammation allows the pathogen to survive well in the host, thus establishing a mutually beneficial relationship. Our current study investigated gene expression at the mRNA level in response to AvrA. Posttranscriptional modification by AvrA cannot be identified by DNA array analysis. Study using Western blot and other protein assay methods will provide further insights into the AvrA’s regulation of eukaryotic proteins

in intestine. Taken together, our findings show that AvrA specifically inhibits inflammatory responses and promotes proliferation in vivo. It is important to understand how AvrA works in vivo because of the Salmonella problems and the bioweapon threat of bacterial toxins. We believe that studies on the action of bacterial effectors will uncover new facets

of bacterial-host interaction that may lead to the development of new therapeutic drugs or vaccines against important human pathogens. Acknowledgements We thank Dr. Constance D.
