Regulatory T cells (Tregs) are increasingly being recognized for their role in promoting tissue repair. In this issue of the JCI, Chen et al. found that Tregs at the site of bone injury contribute to bone repair.

How are autoreactive T cells induced and regulated in patients with autoimmune disease? This question lies at the core of understanding autoimmune disease pathologies, yet it has remained elusive due to host variability and the complexity of the immune system. In this issue of the JCI, Kramer and colleagues used autoimmune hepatitis (AIH) as a model to explore the maintenance of autoreactive CD4+ T cells specific to O-phosphoseryl-tRNA:selenocysteine tRNA synthase (SepSecS). The findings provide insight into the interaction between T cells and B cells in AIH pathogenesis that may reflect a shared mechanism among other autoimmune diseases.

Superantigen-induced (Sag-induced) autoimmunity has been proposed as a mechanism for many human disorders, without a clear understanding of the potential triggers. In this issue of the JCI, McCarthy and colleagues used the SKG mouse model of rheumatoid arthritis to characterize the role of Sag activity in inflammatory arthritis by profiling arthritogenic naive CD4+ T cells. Within the diseased joints, they found a marked enrichment of T cell receptor-variable β (TCR-Vβ) subsets that were reactive to the endogenously encoded mouse mammary tumor virus (MMTV) Sag.
