Immune complexes-mediated activation of neutrophils in systemic lupus erythematosus is dependent on RNA recognition by toll-like receptor 8.

Introduction: Neutrophil activation is important in systemic lupus erythematosus (SLE). We previously demonstrated that ribonucleoprotein (RNP) immune complexes (ICs) promoted neutrophil activation in a TLR7/8-dependent manner. However, it remains unclear if this mechanism occurs in patients.

Evolutionary Conservation of Structural and Functional Coupling between the BRM AT-Hook and Bromodomain.

The BAF chromatin remodeling complex is critical for genome regulation. The central ATPase of BAF is either BRM or BRG1, both of which contain a C-terminal bromodomain, known to associate with acetylated lysines. We have recently demonstrated that in addition to acetyl-lysine binding, the BRG1/BRM bromodomain can associate with DNA through a lysine/arginine rich patch that is adjacent to the acetyl-lysine binding pocket.
