Exposure to bacteria particles and farm dust blunts inflammatory immune responses in children, protecting them from allergies. The protective effect is linked to the anti-inflammatory enzyme A20, which squashes pro-inflammatory molecule generation in lung epithelial cells.
Regulatory T cells (Treg cells) play a critical role in shaping the immune response and maintaining self-tolerance. A recent study by LJI researchers identified a molecular pathway that maintains Treg cell stability and suppressive function, crucial for immune system balance. The discovery suggests that Treg cells may not be stable und...
