About this episode

This episode explores the discovery of ruptoblasts, immune cells that explode to protect the body, as detailed in a new study.

💥 What if an immune cell could defend the body by literally exploding? A fascinating new study in Cell describes "ruptoblasts," a previously unknown cytotoxic cell type in planarian flatworms. Triggered by activin signaling, these cells undergo an explosive form of death called ruptosis , releasing potent diffusible factors that rapidly kill nearby cells and bacteria. 🧬⚡ The work links hormone surveillance with immune defense and uncovers a mechanism distinct from apoptosis, pyroptosis, necroptosis, and ferroptosis. A remarkable glimpse into ancient evolutionary solutions to immunity. 🔬🛡️ #Immunology #CellBiology #PrecisionMedicine #MedicalEducation #MedicalPodcasts #ScienceCommunication #Ruptoblasts #Nature #CellJournal #Innovation
