A maelstrom of migrating monocytes drives neurodegeneration

Immunity. 2023 Dec 12;56(12):2677-2678. doi: 10.1016/j.immuni.2023.11.014.

Abstract

Neurodegeneration is a devastating complication of Langerhans cell histiocytosis (LCH), but it is not clear how it develops. In this issue of Immunity, Wilk et al. demonstrate that circulating BRAFV600E+ myeloid cells damage the blood-brain barrier and infiltrate the brain. Dual inhibition of the MAPK and senescence pathways can block parenchymal injury, providing a potential therapeutic avenue for histiocytic neurodegeneration.
