T cell-microglial interactions that impair myelin maintenance and regeneration: cellular mechanisms on white-matter associated changes
To summarize the cellular and molecular evidence regarding the interactions between microglia and T lymphocytes in the context of aging and white matter changes.
Key Findings:
Aging alters microglial signaling profiles and promotes the recruitment of CD8+ T cells through cytokine signaling.
T cell-derived interferon-gamma induces transcriptional changes in microglia and oligodendrocyte lineage cells, destabilizing myelin.
Maladaptive interactions between microglia and T lymphocytes contribute to myelin deterioration and impaired regenerative capacities.
Interpretation:
Limitations:
The review primarily focuses on murine models, which may not fully represent human pathology.
The specific mechanisms by which genetic variations lead to white matter pathology remain to be elucidated.
