Anti-HSP90α IgG may protect against antiphospholipid syndrome in systemic lupus erythematosus by reducing platelet activation
Natural autoantibodies (NAAbs) are immunoglobulins generated in the absence of antigen provocation, with no inherent pathogenic effect, but instead involved in maintaining immune homeostasis. We aimed to evaluate the implication of immunoglobulin G (IgG) antibodies against heat shock protein 90α (HSP90α) in systemic lupus erythematosus (SLE) patients, focusing on how those NAAbs may interfere with
