This study was fantastically led by @NabinaPun98 working together with @UCytlak. Nabina did an amazing job leading the charge into a new area for our lab and is now at the start of what is going to be a truly fantastic career in research, watch this space for more to come!

💡 Big picture:
Immune cell recruitment isn’t always harmful.
Here, CCR2⁺ monocytes actually protect against injury by supporting IL-17 production and maintaining the intestinal barrier after radiation.

🔍 Why it matters:
Radiotherapy saves lives, but gut toxicity often limits how much treatment patients can tolerate.
By revealing how monocytes and ILC3s cooperate to protect intestinal tissue, we identify new therapeutic opportunities to reduce side effects and improve outcomes.

🧬 What we found:
Abdominal/pelvic radiotherapy can damage healthy intestinal tissue - a major challenge in cancer care.
We discovered a protective immune pathway:
CCR2 → monocyte recruitment → ILC3 → IL-17 → barrier protection

This axis helps the gut resist radiation-induced injury.
