This study focused on toll-like receptor-3, a protein activated by double-strand RNA, which promotes neuroinflammation. The aim was to better understand its expression and role in oligodendrocytes (one of the last types of cell to form in the brain). The in vivo mouse model mimicked white matter injury occurring in preterm babies.

Received: 29 November 2020 / Revised: 8 January 2021 / Accepted: 11 January 2021 / Published: 13 January 2021

This review looks at strategies developed experimentally to modulate microglia and reduce brain injury in babies. It focusses on four causes of perinatal brain injury which occur frequently in both westernised and emerging countries, including EoP and neonatal stroke, and reviews pharmacological approaches as well as novel nanoparticle mediated therapies.
