Abstract
Long-COVID (also termed Post-Acute Sequelae of SARS-CoV-2 or PASC) affects up to 10% of people recovering from SARS-CoV-2 infection. Diagnosis is hampered by diffuse symptomatology, lack of biomarkers, an incomplete understanding of pathogenesis, and the lack of validated treatments. In terms of pathogenesis, hypothesised causes include viral persistence, the legacy of endotheliitis and thrombosis, low-grade tissue-based inflammation and/or scarring, perturbation of the host virome/microbiome, or triggering of autoimmunity. Several studies show pre-existing and/or de novo production of autoantibodies after infection with SARS-CoV-2, but the persistence of these antibodies and their role in causing long-COVID is debated. Here, we review the mechanisms through which autoimmune responses can arise during and after viral infection, focusing on the evidence for B-cell dysregulation and autoantibody production in acute and long-COVID.
期刊介绍：
The Journal of Allergy and Clinical Immunology is a prestigious publication that features groundbreaking research in the fields of Allergy, Asthma, and Immunology. This influential journal publishes high-impact research papers that explore various topics, including asthma, food allergy, allergic rhinitis, atopic dermatitis, primary immune deficiencies, occupational and environmental allergy, and other allergic and immunologic diseases. The articles not only report on clinical trials and mechanistic studies but also provide insights into novel therapies, underlying mechanisms, and important discoveries that contribute to our understanding of these diseases. By sharing this valuable information, the journal aims to enhance the diagnosis and management of patients in the future.
