Leptin promotes systemic lupus erythematosus by increasing autoantibody production and inhibiting immune regulation.

Anti-S Alloantibody Underlying Pan Agglutinating Autoantibody in a Patient of Systemic Lupus Erythematosus

Sources of autoantigens in systemic lupus erythematosus.

PURPOSE OF REVIEW A hallmark of systemic lupus erythematosus is the production of autoantibodies that recognize nuclear antigens. However, the underlying events and mechanisms that lead to the selection of these molecules for the autoimmune response remain poorly understood. In this review, we will examine some of the proposed explanations for sources of systemic lupus erythematosus-specific au...

Autoantibody-dependent and autoantibody-independent roles for B cells in systemic lupus erythematosus: past, present, and future.

It has long been known that B cells produce autoantibodies and, thereby, contribute to the pathogenesis of many autoimmune diseases. Systemic lupus erythematosus (SLE), a prototypic systemic autoimmune disorder, is characterized by high-circulating autoantibody titers and immune-complex deposition that can trigger inflammatory damage in multiple organs/organ systems. Although the interest in B ...

Leptin Enhances Availability of Apoptotic Cell-Derived Self-Antigen in Systemic Lupus Erythematosus

In systemic lupus erythematosus (SLE), the availability of self-antigen promotes and fuels self-reactive immune responses. Apoptotic cells represent a major source of self-antigens, and an impairment of the removal of apoptotic material containing self-antigen can contribute to the development of autoimmunity. To address whether the adipocytokine leptin--which favors autoimmune responses throug...

Mdm2 promotes systemic lupus erythematosus and lupus nephritis.

Systemic lupus erythematosus (SLE) is a polyclonal autoimmune syndrome directed against multiple nuclear autoantigens. Although RNA and DNA seem to have identical immunostimulatory effects on systemic and intrarenal inflammation, each seems to differ with regard to the propensity to induce mitogenic effects such as lymphoproliferation. To identify potential mechanisms by which DNA specifically ...
