A novel assay reveals that T cells in patients with type 1 diabetes produce pro-inflammatory cytokines, driving an autoaggressive immune response. In contrast, healthy individuals' T cells produce regulatory cytokines, maintaining tolerance. The findings offer new approaches to immune modulation and tolerance.
Researchers discovered that a special protein called importin beta is produced at the site of damage in axons, facilitating the entry of molecules into the nucleus. Blocking this process inhibits nerve regeneration, highlighting the need to identify proteins containing the "healing message"
