In this context, obesity, especially during adolescent age, seems to be a key factor for the development of multiple sclerosis. Leptin, the main pro-inflammatory adipokine secreted by the adipose tissue, has been found increased in patients with multiple sclerosis and is able to regulate the immune system promoting a pro-inflammatory response. Leptin signaling in both innate and adaptative immune cells might have immunomodulatory effects in the context of multiple sclerosis. In this way, leptin has been found to produce a Th1 and Th17 response, increasing M1 macrophages and decreasing regulatory T cells and Th2 response. Moreover, circulating inflammatory adipokines, such as leptin, have been found in people with multiple sclerosis.

In this study, we aimed to generate human-induced pluripotent stem cells (hiPSCs) from patients with CADASIL with EGFr 1-6 and 7-34 pathogenic variants to evaluate whether the NOTCH3 position affects the cell phenotype and protein profile of the generated hiPSCs lines. Six hiPSCs lines were generated: two from patients with CADASIL with EGFr 1-6 pathogenic variants, two from patients with EGFr 7-34 variants, and two from controls. Notch3 aggregation and protein profiles were tested in the established six hiPSCs lines. Cell analysis revealed that the NOTCH3 variants did not limit the cell reprogramming efficiency. However, EGFr 1-6 variant position was associated with increased accumulation of Notch3 protein in pluripotent stem cells and proteomic changes related with cytoplasmic reorganization mechanisms.

ADAR1 p150 plays a significant role in immune regulation and stress responses; however, the specific pathways through which it modulates microglial activation and the subsequent mechanisms that unfold following IS have yet to be clearly delineated. The distal middle cerebral artery occlusion (dMCAO) mouse model was utilized to induce IS. The evaluation of infarct volume was conducted through TTC staining, while neurological function was assessed using the modified Neurological Severity Score (mNSS). To evaluate the expression of ADAR1 and apoptosis-related proteins, immunofluorescence and Western blot techniques were employed. BV2 cells were subjected to oxygen-glucose deprivation followed by reperfusion (OGD/R). Additionally, a co-culture system of BV2 cells and neurons was established, and subsequent assessments of neuronal viability and apoptosis were performed using CCK-8 assays and LDH release assays. ADAR1 p150 expression was significantly upregulated in the brains of ischemic mice, particularly within microglial cells. The overexpression of ADAR1 p150 was found to promote microglial activation and enhance pro-inflammatory responses, whereas the knockdown of ADAR1 p150 yielded the opposite effect. Additionally, the knockdown of ADAR1 p150 in microglia resulted in a marked reduction in neuronal apoptosis within the co-culture system. Rescue experiments indicated that the knockdown of NUPR1 partially reinstated the inflammatory response previously induced by ADAR1 p150 knockdown. Notably, ADAR1 p150 knockdown also inhibited A-to-I RNA editing while simultaneously upregulating NUPR1. Furthermore, the reduction of ADAR1 expression was associated with decreased infarct volume, improved neurological outcomes, and a significant attenuation of neuroinflammation in dMCAO mice.

Outcomes measured included hematoma volume, microtubule stability (acetylated α-tubulin), levels of inflammatory cytokines, mitogen-activated protein kinase (MAPK) pathway activity, neuronal degeneration (Fluoro-Jade C staining), and cell integrity (Cresyl Violet staining).

TUBB6 expression increased with the severity of hemorrhage in the ICH models. TUBB6 ASO significantly reduced hematoma volume at 24- and 72-h post-ICH, restored acetylated α-tubulin levels, suppressed MAPK signaling pathway, and decreased pro-inflammatory markers with increased IL-10. TUBB6 ASO also reduced neuronal degeneration and improved cell viability. In terms of functional outcomes, the TUBB6 ASO + ICH group exhibited reduced mNSS scores, improved body weight maintenance, and better performance on corner turn, forelimb-placing and rotarod tests compared to the Control ASO + ICH group.

A control group received no bacteria intervention. Behavioral deficits were assessed using grip-traction, beam-walking, and grid-walking tests. Oxidative stress biomarkers were quantified using colorimetric assays. The extent of demyelination was evaluated by hematoxylin and eosin staining of the corpus callosum. Serum levels of vitamin D₃ and B₁₂ were measured by ELISA. The results demonstrated that lactic acid bacteria supplementation significantly improved behavioral deficits and reduced demyelination in the corpus callosum. Furthermore, these bacteria administration was associated with reduced oxidative stress and increased serum levels of vitamin D₃ and B₁₂.
