Monocytes Inadequately Fill In for Meningeal Macrophages

Trends Immunol. 2019 Jun;40(6):463-465. doi: 10.1016/j.it.2019.04.004. Epub 2019 May 6.

Abstract

In the meninges, a unique subset of tissue-resident macrophages serves as a sentinel population against invading microorganisms while suppressing harmful inflammation. A recent report shows that when murine meningeal macrophages are killed by viruses, circulating monocytes repopulate the open niche. However, they fail to mimic all aspects of tissue-resident macrophages.
