Type IV pilin structure and assembly: X-ray and EM analyses of Vibrio cholerae toxin-coregulated pilus and Pseudomonas aeruginosa PAK pilin.

abstract：:To unravel the roles of LXRs in inflammation and immunity, we examined the function of LXRs in development of IFN-gamma-mediated inflammation using cultured rat brain astrocytes. LXR ligands inhibit neither STAT1 phosphorylation nor STAT1 translocation to the nucleus but, rather, inhibit STAT1 binding to promoters and...
