Hypothetical models of the effect of macrophages differentiated in the presence of MP-IC in the RA and SLE pathogenesis. Proposed hypothetical model of the dynamic of interaction between MP-IC and monocytes in circulation and their potential contribution to promote macrophages differentiation to a proinflammatory profile in the tissues of patients with seropositive RA (A) and patients with active SLE (B); these activated macrophages contribute to T cell activation and expansion, and B cell survival and production of antibodies; therefore, MP and specially MP-IC can participate in the pathophysiology of these autoimmune diseases, favoring the perpetuation of the chronic inflammation and autoimmune responses that affect the tissues of RA (joint, A) and SLE (kidney, B) patients.
