Incidence and prevalence of autoimmune disease in the Swedish National Patient Register - European Journal of Epidemiology European Journal of Epidemiology - Standardized definitions of autoimmune disease (AD) are lacking. Therefore, we aim to propose a definition of AD for register-based research and estimate the...

New paper📢 - how many individuals are affected by an autoimmune disease. Together with epidemiology experts jonas Ludvigsson @ki.se we use 🇸🇪 population registry and find that 1/13 adults and 1/67 children are affected by autoimmunity: link.springer.com/article/10.1...

Expanding the scope of human immunology in the Journal of Human Immunity. New Editorial from Petter Brodin @petterbrodin.bsky.social, Megan Cooper @macattacklab.bsky.social, Jean-Laurent Casanova @casanovalab.bsky.social, and colleagues in the JHI Editorial team:

Tissue Regulatory T Cells FOXP3+ regulatory T cells (Tregs) have well-defined roles in limiting systemic immune responses against diverse stimuli. However, the observation that a subset of Tregs also enter nonlymphoid tissues,...

Our latest review is out, a comprehensive synthesis of #tissue #Tregs. It has been a decade since @annualreviews.bsky.social #immunology last reviewed #TissueTregs, and there have been enormous advances and conceptual leaps forward in the field

Immunity debt: does it really exist? Some claim the rise in winter infections has been caused by the reduction of seasonal bugs during lockdowns. But experts are sceptical about these oversimplified explanations

The term “immunity debt” was first introduced by French researchers in 2021. It refers to a population-wide effect rather than an individual-level one.
