miRNA-192-5p targets Dyrk1a to attenuate cerebral injury in MCAO mice by suppressing neuronal apoptosis and neuroinflammation.

Introduction: Ischemic stroke (IS) is a leading cause of disability and mortality worldwide. Several studies have demonstrated the involvement of microRNAs (miRNAs) in brain diseases. miRNA-192-5p is a regulatory molecule in neurodegenerative diseases and its expression was found to be significantly downregulated in the whole blood samples of IS patients, but the specific role of miRNA-192-5p in IS not fully understood.

Regulation of TREM2 on BV2 inflammation through PI3K/AKT/mTOR pathway.

This work sought to determine how lipopolysaccharide (LPS)-induced pro-inflammatory factor production in BV2 microglia was influenced by myeloid cell 2 (TREM2) expressions. LPS (0.1, 1, and 10 µg/mL) induced inflammation in BV2 cells, MTT and QPCR were used to detect the occurrence of inflammation; TREM2 activation and inhibition vectors were used to activate and inhibit TREM2; Cell Proliferation was detected using CCK-8 and cell cloning experiments.

Genipin protects against mitochondrial damage of the retinal pigment epithelium under hyperglycemia through the pathway mediated by the signaling axis.

Background: To investigate the protective effect and mechanism of genipin (GE) on mitochondrial damage in retinal pigment epithelial (RPE) cells induced by high glucose.

Methods: Differential genes of GE in the treatment of diabetic retinopathy (DR) were screened by the Gene Expression Omnibus (GEO) database. Differential genes located in the pathway were obtained.

Ferrostatin-1 Polarizes Microglial Cells Toward M2 Phenotype to Alleviate Inflammation After Intracerebral Hemorrhage.

Background: Intracerebral hemorrhage (ICH) is one of the most lethal stroke types and lacks effective therapeutic regimens. Recently, evidence has suggested the involvement of the ferroptosis inhibitor ferrostatin-1 (Fer-1) in the pathophysiological process of ICH. In this study, we examined the underlying mechanism.

Milrinone Ameliorates the Neuroinflammation and Memory Function of Alzheimer's Disease in an APP/PS1 Mouse Model.

Purpose: Alzheimer's disease (AD) is a complex neurodegenerative disorder, which is characterized by memory loss and cognitive deficits. The neuroprotective role of milrinone on the injury of spinal cord or cerebral ischemia-reperfusion has been confirmed. However, the accurate function of milrinone on AD pathogeny is still unclear.
