FABP4 and infection: Conversely, H37Rv infection induced the up-regulation of two interferon-induced proteins (IFIT1 and IFIT3) and the down-regulation of eight other proteins (including S100A6, FABP4, FABP5, GABARAPL2, and LGALS1), but M. bovis or BCG infection induced non-significant changes in the levels of these proteins.
