Researchers at Stanford University have identified a novel type of immune cell that annihilates threats through a detonation mechanism, vanishing within minutes without leaving any remnants. Observed in planarian flatworms, renowned for their ability to regenerate from minor segments, these cells have been termed 'ruptoblasts' due to their explosive defense strategy. As detailed in the journal Cell, the hormone activin initiates the rupture, discharging toxic agents that eliminate surrounding bacteria and foreign cells before the ruptoblast itself is lost. Unlike T-cells and other immune cells derived from blood, ruptoblasts originate from glands and their destructive burst remains highly localized. The cells were evaluated against E. coli, human kidney cells, and mouse blood, with researchers suggesting that this finding could lead to innovative, targeted therapies for infections and tumors.
