title: Influenza A virus infection activates cholesterol sulfotransferase (SULT2B1b) in the lung of female C57BL/6 mice.
abstract: Cytosolic sulfotransferases (SULTs) catalyze the sulfation of hormones, neurotransmitters, and xenobiotics, increasing their water solubility. SULTs are not only important for xenobiotic detoxification but they also play important biological roles in the regulation of the activities of various biosignaling molecules and other cellular functions. In this study, we investigated the effects of influenza A virus lung infection on the expression of SULTs in the lung, brain, and liver of female C57BL/6 mice. Our results demonstrate for the first time that SULT2B1b enzyme activity and protein expression are significantly up-regulated in the lung and brain of female mice in response to lung influenza A virus infection. Real-time quantitative PCR results are consistent with Western blot and enzymatic activity data. In mouse liver, mSULT2B1b is not significantly changed. Enzyme activities, protein expression, and mRNA expression of SULT1A1 and SULT2A1 in the lung, brain, and liver of mice were not significantly affected by the infection. The induction of SULT2B1b may be used to inactivate natural liver X receptor ligands and activate the proliferation of T cells in response to influenza A virus infection in the lung and brain of mice. Our results raise the possibility that regulation of SULT2B1b may influence acquired immune responses to infectious diseases.
