Web10 apr. 2024 · After 24 hr of LPS treatment, astrocyte release of TNF-α, IL-6, and IL-10 were all increased compared to vehicle-treated controls (p < .0001, p = .0002, and p = .0028, respectively; Figure 1d,f,h). Astrocyte viability was not negatively affected by treatment with LPS after 24 hr, with >90% cell viability, in both LPS and vehicle-treated … Web3 sep. 2024 · To assess whether reactive astrocyte responses differ based on the insult given, they analyzed differentially expressed genes in reactive astrocytes that were induced either by experimental ischemic stroke or by neuroinflammation [through systemic administration of lipopolysaccharide (LPS; Zamanian et al., 2012)] and subsequently …
WebFurthermore, astrocyte activation was still increased in LPS-treated mice at 24 h, thereby indicating the relevance of measuring glial activation at this point. Factorial ANOVA indicated a significant effect of dose ( , ), and post hoc analysis showed that the pixel number of IBA1 positive cells was significantly higher in mice that received LPS when … Web1 mrt. 2024 · In astrocytes, Piezo1 activation is associated with the pathogenesis of central nervous system neurodegeneration. Expression of Piezo1 has been detected in mouse optic nerve head astrocytes, however, the functional role of Piezo1 has not been identified. In this study, we investigated the role of Piezo1 in optic nerve head astrocyte reactivity.
Web26 jan. 2024 · There is strong evidence for blood-brain and blood-spinal cord barrier (BBB, BSCB) dysfunction at the early stages of many neurodegenerative diseases (NDDs), including amyotrophic lateral sclerosis (ALS). 1,2 Since impairment of the blood-central nervous system barrier (BCNSB) occurs during the pre-symptomatic stages of ALS, the … Web14 apr. 2024 · Abstract Among the responses in the early stages of stroke, activation of neurodegenerative and proinflammatory processes in the hippocampus is of key importance for the development of negative post-ischemic functional consequences. However, it remains unclear, what genes are involved in these processes. The aim of this work was …
WebMaR1 substantially inhibited the mRNA and protein expression of NF-κB p65 and κB inhibitor kinase β. Collectively, these results suggest that MaR1 ameliorated splenectomy-induced transient cognitive impairment in elderly rats, and this neuroprotective mechanism may occur through regulating the NF-κB pathway to inhibit astrocyte activation.
