Area of Science:

Neuroimmunology
Evolutionary Biology
Cell Biology

Background:

Microglial cells are unique macrophages residing in the central nervous system (CNS) parenchyma.
A recent comparative study analyzed microglial transcriptomes across diverse species, from leeches to humans.
Understanding microglial evolution is key to deciphering conserved and divergent pathways.

Purpose of the Study:

To investigate the evolutionary history and conserved features of microglial cells.
To explore the implications of microglial evolution for developing novel CNS disorder therapies.
To re-evaluate the understanding of sex specificity in the CNS immune system.

Main Methods:

Comparative transcriptional analysis of microglial cells across over 20 species.
Identification of conserved genetic features and evolutionary pathways of microglia.
Re-examination of the CNS immune cell landscape, including CNS-associated macrophages (CAMs).

Main Results:

Microglia exhibit highly conserved features across a vast evolutionary timescale (over 500 million years).
The study identified multiple conserved characteristics of microglia, underscoring their vital role.
CNS-associated macrophages (CAMs) were identified as CNS interface residents, co-evolving with microglia.

Conclusions:

Microglial evolution provides critical insights into conserved and divergent pathways, impacting CNS disorder therapies.
Future therapeutic strategies for CNS disorders may need reevaluation based on microglial evolution.
The identification of CAMs updates the paradigm of CNS-resident immune cells and their evolutionary history.
