Abstract: Anti-cytokine therapy has revolutionized immunological disease treatment, but is not always effective and subject to treatment resistance as the cytokine cascade is highly redundant and multiple cytokines are involved in inflammation. Targeting a critical common regulator of inflammatory effectors is desirable. Lipopolysaccharide (LPS)-responsive beige-like anchor (LRBA) is a master regulator of multiple genes important for inflammation. Subcellular localization shows that LRBA translocated to the nucleus upon LPS stimulation and colocalized with multiple proteins associated with the endosome membrane system, indicating a critical role in membrane/vesicle trafficking essential for deposition, secretion and signal transduction of immune effectors.
