Systemic lupus erythematosus (SLE) is an autoimmune disease whose pathogenesis is not fully understood to date. One of the suggested mechanisms for its development is NETosis, which involves the release of a specific network consisting of chromatin, proteins, and enzymes from neutrophils, stimulating the immune system. One of its markers is citrullinated histone H3 (H3Cit).

Current diagnosis and treatment of rheumatoid arthritis (RA) is still challenging. More than one-third of patients with RA could not be accurately diagnosed because of lacking biomarkers. Our recent study reported that scavenger receptor-A (SR-A) is a biomarker for RA, especially for anticyclic citrullinated peptide antibody (anti-CCP)-negative RA.

Two broad classes of mechanisms have emerged for understanding the Amyloid-Related Imaging Abnormalities (ARIA) associated with anti-beta-amyloid immunotherapy. One set of mechanisms proposes that ARIA is driven by large-scale transfer of antibody-bound amyloid from brain parenchyma to the perivascular and vascular compartments. This class of mechanisms is indirectly supported by neuropathological evidence that immunotherapy substantially clears plaque amyloid while increasing vessel-associated amyloid, but has been difficult to directly demonstrate.

Background: Chitinase-3-like protein 1 (CHI3L1, or YKL-40) is an important regulator of immunity and, in the brain, is primarily secreted by activated astrocytes and heralds a neurotoxic inflammatory state. While it has been well known as a high-profile biomarker for Alzheimer's disease (AD) and inflammatory brain conditions (e.g.

ARIA-E/H (amyloid-related imaging abnormalities-Edema/Hemorrhage) is an umbrella term that defines the radiographic appearance of MRI images abnormality during treatments with Aβ-lowering monoclonal antibodies (mAbs) for Alzheimer's disease immunotherapy. Today, it is well-recognized that ARIA-E events can also occur spontaneously in patients with cerebral amyloid angiopathy-related inflammation (CAA-ri), a rare autoimmune encephalopathy associated with raised cerebrospinal fluid (CSF) concentrations of spontaneous auto-antibodies against Aβ (aAbs). In this framework, the last years of research and experience of the iCAB international Network generated an increased consensus that therapy-induced ARIA is the iatrogenic manifestation of CAA-ri.
