IFNG and infection: To test this hypothesis, in this current study a series of experiments were designed first, (a) to determine the influence of IFN-γ alone on bronchial epithelial cell expression of both mICAM-1 and sICAM-1 forms at the protein and gene level; and (b) to examine the consequences of IFN-γ cell preconditioning on subsequent HRV binding and infection.
