DARE Cells and Tissue Regeneration 🧬 | What Did the 2026 Study Discover? | Current Affairs 2026

Q. What are DARE cells associated with in the 2026 tissue-regeneration study?
✅ Answer: Tissue regeneration through compensatory proliferation.
Scientists studying Drosophila (fruit flies) identified DARE cells — Dronc-activating radiation-induced apoptosis-resistant epithelial cells. These cells survive radiation-induced cell death and then multiply to help repair and regenerate damaged tissue. PubMed
🔑 Key Facts:
– 🧬 DARE: Dronc-activating radiation-induced apoptosis-resistant epithelial cells
– 🪰 Model organism: Drosophila (fruit fly)
– ☢️ Trigger studied: Ionising radiation
– 🔄 Main role: Compensatory proliferation and tissue regeneration
– 🧫 DARE cells activate Dronc, an initiator caspase, but avoid apoptosis.
– 🔬 They also stimulate neighbouring NARE cells to proliferate.
– 🧩 The study highlights an unexpected role of caspase activity in tissue repair and regeneration. Nature
