Our results showed that ASK1 silencing effectively reduced Iba-1 or CD11b-positive cells in ischemic areas, suppressed pro-inflammatory cytokines, and increased anti-inflammatory mediator levels at 7 days after cerebral ischemia.
Notably, TMEM119 immunoreactivity was expressed exclusively on a subset of Iba1(+) CD68(+) microglia with ramified and amoeboid morphologies in the brains of neurodegenerative diseases, such as Alzheimer's disease (AD), whereas Iba1(+) CD68(+) infiltrating macrophages do not express TMEM119 in demyelinating lesions of multiple sclerosis and necrotic lesions of cerebral infarction.
