Anti-PL antibodies, comprising anti-cardiolipin (CL), anti-b2 glycoprotein 1 (b2GP1), and lupus anticoagulant, have been found to be involved in thrombotic events in SLE and have been linked to vascular changes in NPSLE [48], although conflicting results have been published [6]. Here, APOH is linked to systemic lupus erythematosus.
