Abstract:
Stroke encompasses a range of cerebrovascular disorders characterized by high morbidity, disability, and mortality, with ischemic stroke being the predominant type. This condition imposes significant socio-economic and healthcare burdens, and therapeutic options are currently limited. Microglia, the brain's resident immune cells, are rapidly activated following stroke-induced injury and play a pivotal role in the pathogenesis of neuroinflammation and ischemic tissues. Mitochondria participates in and influences the pathological processes of ischemic stroke, including oxidative stress, modulation of microglia phenotype, and axonal regenerative function, and is an essential and often overlooked target in the clinical management of stroke. This paper reviews recent advancements in research on microglia in ischemic stroke, specifically focusing on the contribution of the mitochondria, providing a reference for selecting therapeutic targets and guiding future research directions.
Insights

Area of Science:
- Neuroscience
- Immunology
- Cell Biology
Background:
- Stroke, particularly ischemic stroke, presents a major global health challenge with significant morbidity and mortality.
- Current therapeutic strategies for stroke are limited, necessitating the exploration of novel treatment targets.
- Microglia, the central nervous system's immune cells, are critically involved in the inflammatory response following ischemic injury.
Purpose of the Study:
- To review recent research on the role of microglia in ischemic stroke.
- To elucidate the specific contribution of mitochondria to microglial function and dysfunction in stroke pathogenesis.
- To identify mitochondria as a potential therapeutic target for stroke management.
Main Methods:
- Literature review of recent scientific publications.
- Analysis of studies investigating microglial activation post-stroke.
- Examination of research on mitochondrial involvement in neuroinflammation and neuronal repair.
Main Results:
- Microglia activation is a key event in the inflammatory cascade following ischemic stroke.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
