Preconditioned extracellular vesicles from hypoxic microglia reduce poststroke AQP4 depolarization, disturbed cerebrospinal fluid flow, astrogliosis, and neuroinflammation
(NLM (Medline), 2023)
Background: Stroke stimulates reactive astrogliosis, aquaporin 4 (AQP4) depolarization and neuroinflammation. Preconditioned extracellular vesicles (EVs) from microglia exposed to hypoxia, in turn, reduce poststroke brain ...
TGF-β1 decreases microglia-mediated neuroinflammation and lipid droplet accumulation in an in vitro stroke model
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Hypoxia triggers reactive microglial inflammation and lipid droplet (LD) accumulation under stroke conditions, although the mutual interactions between these two processes are insufficiently understood. Hence, the involvement ...
TREM2 regulates microglial lipid droplet formation and represses post-ischemic brain injury
(Elsevier Masson s.r.l., 2024)
Triggering receptor expressed on myeloid cells 2 (TREM2) is a transmembrane receptor protein predominantly expressed in microglia within the central nervous system (CNS). TREM2 regulates multiple microglial functions, ...
Knockdown of NEAT1 prevents post-stroke lipid droplet agglomeration in microglia by regulating autophagy
(Springer Science and Business Media Deutschland GmbH, 2024)
Background: Lipid droplets (LD), lipid-storing organelles containing neutral lipids like glycerolipids and cholesterol, are increasingly accepted as hallmarks of inflammation. The nuclear paraspeckle assembly transcript 1 ...
Social isolation initiated post-weaning augments ischemic brain injury by promoting pro-inflammatory responses
(Academic Press Inc., 2024)
Social isolation is associated with poor stroke outcome, but the underlying molecular mechanisms were largely unknown. In male Balb/C mice exposed to transient middle cerebral artery occlusion (MCAo), we examined the effects ...
