title: Cytokine, chemokine and chemokine receptor mRNA expression in different strains of normal mice: implications for establishment of a Th1/Th2 bias.
abstract: The resistance or susceptibility of inbred strains of mice to various pathogens and autoimmune diseases such as EAE has been linked to differences in the balance between cytokines associated with Th1- and Th2-type immune responses. Previous work from this laboratory on the mouse strain specific resistance to mouse adenovirus type I (MAV-1)-induced encephalopathy revealed subtle differences in the transcription rates of several immunologically important molecules that was evident prior to infection. In this study, we show striking differences in cytokine, chemokine and chemokine receptor mRNA expression in the spleens of normal, immunologically naive C57BL/6J, BALB/cJ and SJL/J mice. Messenger RNAs for interferon (IFN)-gamma and the chemokine IFN gamma inducible protein (IP)-10 were preferentially expressed in C57BL/6J spleens, whereas in BALB/cJ spleens mRNAs for lymphotoxin-beta, interferon-beta, transforming growth factor-beta, and the chemokine receptors CCR3 and CXCR4 predominated. A unique profile of chemokine receptors was found in spleens from normal SJL/J mice that correlated with the presence of polymorphisms within the CCR-3 gene. The patterns of gene expression fit well into the Th1/Th2 paradigm for C57BL/6J and BALB/cJ strains and suggest an important role for chemokines, as well as cytokines, in contributing to the genetic basis of the immune response.
