Immune-related actinopathies at the cross-road of immunodeficiency, autoimmunity and autoinflammation
Actin cytoskeleton remodelling drives the migration of immune cells and their engagement in dynamic cell–cell contacts. The importance of actin cytoskeleton dynamics in immune cell function is highlighted by the discovery of inborn errors of immunity (IEIs) that are caused by defects in individual actin-regulatory proteins, resulting in immune-related actinopathies. In addition to susceptibility to infection, these often present with a vast array of autoimmune and autoinflammatory manifestations. Here, we review the role of actin subnetworks in the activation and function of lymphoid and myeloid cells. We focus on the mechanisms by which actin defects result in aberrant lymphocyte function, including dysregulation of T cell- and B cell-mediated tolerance and biased cytokine production, which can result in autoimmunity. We also highlight the relationship between actin defects and inflammasome activation and other pathomechanisms in myeloid cells as the underlying cause of autoinflammation. Finally, we discuss future avenues for research and therapeutic intervention based on a molecular understanding of immune-related actinopathies.
期刊介绍:
Nature Reviews Immunology is a journal that provides comprehensive coverage of all areas of immunology, including fundamental mechanisms and applied aspects. It has two international standard serial numbers (ISSN): 1474-1733 for print and 1474-1741 for online. In addition to review articles, the journal also features recent developments and new primary papers in the field, as well as reflections on influential people, papers, and events in the development of immunology. The subjects covered by Nature Reviews Immunology include allergy and asthma, autoimmunity, antigen processing and presentation, apoptosis and cell death, chemokines and chemokine receptors, cytokines and cytokine receptors, development and function of cells of the immune system, haematopoiesis, infection and immunity, immunotherapy, innate immunity, mucosal immunology and the microbiota, regulation of the immune response, signalling in the immune system, transplantation, tumour immunology and immunotherapy, and vaccine development.
