Interplay between interleukin-6 signaling and the vascular endothelium in cytokine storms.

Exp Mol Med 2021 Jul 12. Epub 2021 Jul 12.

Laborabory of Immune Regulation, Immunology Frontier Research Center, Osaka University, 3-1 Yamadaoka, Suita, Osaka, Japan.

Interleukin-6 (IL-6) plays a crucial role in host defense against infection and tissue injuries and is a bioindicator of multiple distinct types of cytokine storms. In this review, we present the current understanding of the diverse roles of IL-6, its receptors, and its signaling during acute severe systemic inflammation. IL-6 directly affects vascular endothelial cells, which produce several types of cytokines and chemokines and activate the coagulation cascade. Read More

Nothing about us without us: involving patient collaborators for machine learning applications in rheumatology.

Ann Rheum Dis 2021 Jul 5. Epub 2021 Jul 5.

Centre for Health Informatics, The University of Manchester, Manchester, UK.

Novel machine learning methods open the door to advances in rheumatology through application to complex, high-dimensional data, otherwise difficult to analyse. Results from such efforts could provide better classification of disease, decision support for therapy selection, and automated interpretation of clinical images. Nevertheless, such data-driven approaches could potentially model noise, or miss true clinical phenomena. Read More

New developments implicating IL-21 in autoimmune disease.

J Autoimmun 2021 Aug 2;122:102689. Epub 2021 Jul 2.

Devision of Rheumatology, Department of Medicine, Penn State MS Hershey Medical Center, Hershey, PA, 17033, USA.

Elevated interleukin (IL)-21 is a common finding in the tissues and/or sera of patients with autoimmune disease. CD4 T cells are the primary producers of IL-21; often the IL-21 producing CD4 T cells will express molecules associated with follicular helper cells (T). Recent work has shown that the CD4 T cell-derived IL-21 is able to promote effector functions and memory differentiation of CD8 T cells in chronic infections and cancer. Read More
