In a recently published review, researchers led by Prof. Wu Qingfeng at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences explored the ongoing process of neural cell competition (NCC), a fundamental mechanism that shapes the brain across the lifespan.

The review is published in National Science Review, and provides fresh insights into how brain cells continuously “compete” for survival and how this competition impacts brain development, wiring, function, and aging.

Although neural cell competition is widely recognized for its role during early brain development, Prof. Wu’s team demonstrated that this process continues to be vital throughout life. They revealed that NCC not only helps maintain healthy brain function but also contributes to age-related cognitive decline when disrupted.
