SIR, CD180 (RP105) is a leucine-rich repeat (LRR) molecule expressed on the membrane of B-cells [1, 2]. The molecules bearing LRRs control the recognition of pathogens and the subsequent activation of the immune system [3, 4]. CD180 belongs to the toll-like receptor family of pathogen receptors. CD180 takes part in B-cell recognition and lipopolysaccharide signalling [5].
Recent studies have shown decreased CD180 expression on B-cells in systemic lupus erythematosus
