A lot of ideas, discussions and collaboration went into this one. 🧬🐟. Our new review explores how transcription factor networks orchestrate immune responses in teleosts and how much more there is to uncover beyond the mammalian view www.frontiersin.org/journals/imm...

New-found immune cells called ‘ruptoblasts’ explode when triggered, ejecting toxic chemicals capable of delivering death to surrounding cells in just minutes. The cells’ discoverers say that this process, which they call ruptosis, seems to be a new form of cell death.

Bang! Exploding immune cells splatter potent toxins everywhere
Detonation of newly discovered ‘ruptoblasts’, found in flatworms, releases compounds that kill nearby cells in minutes.
