Chinese scientists identify microglia in peripheral nervous system for first time
The finding paves the way for more accurate disease models
A team of Chinese scientists has confirmed the existence of microglia in the peripheral nervous system (PNS) for the first time, marking an advance in neuroscience and offering promising new directions for treating neurological and developmental disorders. This is reported by China Daily, a partner of TV BRICS.
The research conducted under the Chinese Academy of Sciences challenges the long-standing assumption that microglia are exclusive to the central nervous system (CNS), significantly expanding current understanding of immune cell function in neural development and disease.
In total, the research team analysed tissues from 24 species, including fish, amphibians, reptiles, and mammals. Their results show that PNS microglia likely emerged over 450 million years ago, tracing back to a common ancestor of bony fish.
The presence of microglia in the PNS opens entirely new avenues for investigating and treating neurological disorders. For example, their activity could influence congenital nervous system malformations, immune responses to nerve injury, and mechanisms of neural regeneration.
According to the source, this breakthrough paves the way for more accurate disease models and the development of new therapeutic strategies targeting microglial behaviour in the PNS.

Vladimir PutinPresident of Russia"We are developing mutual trade, which is growing; it increased by over 12 per cent last year. We have a joint commission working in this sphere. Our focus is on agriculture, shipbuilding, information technology and energy, including nuclear power. We have signed a free trade agreement between the Eurasian Economic Union and Indonesia. Jakarta is our reliable and old friend within ASEAN. We are working together at all international platforms, including the UN" -

Joao Paulo CapobiancoBrazilian Minister of the Environment and Climate Change"The BRICS countries have a very high level of responsibility because they share an important part of the world's biodiversity, landscapes, populations, food production and water resources. So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification"
