Stem cell therapy has emerged as a new promising therapeutic strategy for intracerebral hemorrhage (ICH). However, the efficiency of stem cell therapy is partially limited by low retention and engraftment of the delivered cells. Therefore, it's necessary to improve the migration ability of stem cells to the injured area in order to save the costs and duration of cell preparation. This study aimed to investigate whether overexpression of CX3CR1, the specific receptor of chemokine fractalkine (FKN), in adipose-derived stem cells (ADSCs) can stimulate the cell migration to the injured area in the brain, improve functional recovery and protect against cell death following experimental ICH. ADSCs were isolated from subcutaneous adipose tissues of rats. ICH was induced by means of an injection of collagenase type VII. ELISA showed that the expression levels of fractalkine/FKN were increased at early time points, with a peak at day 3 after ICH. And it was found that different passages of ADSCs could express the chemokine receptor CX3CR1. Besides, the chemotactic movements of ADSCs toward fractalkine have been verified by transwell migration assay. ADSCs overexpressing CX3CR1 were established through lentivirus transfection. We found that after overexpression of CX3CR1 receptor, the migration ability of ADSCs was increased both and . In addition, reduced cell death and improved sensory and motor functions were seen in the mice ICH model. Thus, ADSCs overexpression CX3CR1 might be taken as a promising therapeutic strategy for the treatment of ICH.

Background: Retinal degeneration (RD) is a chronic retinopathy that characterized by the progressive photoreceptor apoptosis and visual impairments. However, due to the complicated pathogenesis of RD, there is no effective treatment at present. This study intends to verify the therapeutic effect and mechanism of stanniocalcin-1 (STC-1) in the sodium iodate (NaIO)-induced RD mouse model.

Neuroinflammation is a complicated and multifactorial reaction in the central nervous system (CNS) that contributes to the pathophysiology of many neurological illnesses, such as neurodegenerative diseases and traumatic brain injury. Circular RNAs (circRNAs) have been identified to play important regulatory roles in neuroinflammatory diseases, making for novel therapeutic concerns. This review provides an overview of recent studies targeting the modulation of circRNA to aid in neuroinflammation, utilizing both silencing and overexpression strategies to facilitate possible neuron protection from neuroinflammatory insults.

Cerebral ischemia-reperfusion injury (CIRI) induces significant microglial inflammation. V-type immunoglobulin domain-containing suppressor of T cell activation (VISTA), a novel inhibitory immune checkpoint, participates in myeloid cell metabolism. This study aims to investigate the molecular mechanisms of VISTA's protective effects on CIRI by modulating microglial metabolism.

Background: Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous disease with variable clinical and molecular features. Studies have highlighted the significant role of γδ T cells in the survival of leukemia patients. However, the heterogeneity of γδ T cells and their impact on clinical correlation in the peripheral blood of patients with DLBCL remain unclear.

eggs in the host liver form granuloma and liver fibrosis and then lead to portal hypertension and cirrhosis, seriously threatening human health. Natural killer (NK) cells can kill activated hepatic stellate cells (HSCs) against hepatic fibrosis. We used single-cell sequencing to screen hepatic NK cell subsets against schistosomiasis liver fibrosis.
