Summary: The study explored the effect of kellerin on cerebral ischemia and its possible mechanisms using MCAO model and LPS-activated microglia model. Kellerin improved neurological outcome, reduced brain infarct size, and alleviated neuron damage by inhibiting microglial activation under pathologic conditions of focal cerebral ischemia. In in vitro studies, kellerin protected neuronal cells from damage by suppressing pro-inflammatory cytokines, NF-kappa B signaling pathway, ROS generation, and NADPH oxidase activity.

Summary: p38α is a protein kinase that regulates cellular responses to various stresses. We identified 35 proteins and 82 phosphoproteins that are modulated by p38α and highlighted the involvement of protein kinases MK2 and mTOR in p38α-regulated signaling networks. Our results provide valuable information on p38α-dependent phosphorylation events in cancer cells and reveal a mechanism by which p38α regulates cell adhesion.

Summary: In this study, a novel SFK homologue (AjSrc) was identified in Apostichopus japonicus, which mediated Vibrio splendidus-induced coelomocytes' phagocytosis via interacting with focal adhesion kinase (AjFAK) and co-phosphorylation. This study enriched the mechanism of phagocytosis in echinoderm and provided a new theoretical foundation for disease control of sea cucumber.

Summary: Inflammatory bowel diseases (IBDs) are genetically complex and exhibit significant inter-patient heterogeneity. Mouse models of IBD show varied responses to MK2 inhibition, with MK2 suppressing inflammation by targeting inflammatory cells. Using a computational approach, researchers identified IBD patient subgroups predicted to respond to MK2 inhibition, which can aid in identifying which patients will benefit from new therapies.

Summary: During canonical Wnt signaling, Wnt induces the endocytosis of focal adhesion proteins and depletion of Integrin beta 1 from the cell surface. This endocytosis leads to changes in the cytoskeleton and is accompanied by the sequestration of Integrin beta 1 within membrane-bounded organelles containing glycogen syntase kinase 3 and focal adhesion-associated proteins.

Summary: This study aimed to investigate the effects of Akkermansia muciniphila (A. muciniphila) on heat stress-induced dysfunction of intestinal permeability and its preventive effects on heatstroke. The results showed that both live and pasteurized A. muciniphila effectively attenuated the decrease in intestinal permeability caused by heat exposure. Additionally, A. muciniphila significantly elevated the expression of tight junction proteins Occludin and ZO-1 by promoting HSP27 phosphorylation, thereby preventing the distortion and redistribution of tight junction proteins and maintaining the integrity of intestinal morphology.

Summary: This study demonstrates that B cells in patients with NMOSD are abnormally skewed towards antibody-secreting cells at the transcriptome level during the early differentiation phase, and IL-2 might participate in this pathogenic process. CD25(+) naive B cells are identified as a novel candidate precursor of antibody-secreting cells in autoimmune diseases.

Summary: Mislocalization and cytoplasmic aggregation of TDP-43 in spinal cord motor neurons have been found in various neurological disorders, suggesting mechanistic links. Additionally, the severity of TDP-43 pathology in the spinal cord correlates with the severity of 4R-tau aggregates. These findings provide insights into the pathology and potential mechanisms underlying TDP-43-related diseases.

Summary: This study combined NODDI and SyMRI to evaluate GM microstructural alterations in RRMS and NMOSD patients, revealing reduced NDI and MVF and increased ODI and ISOVF in RRMS patients, mainly in limbic and paralimbic regions, while NMOSD patients showed reduced NDI in different cortical areas. RRMS and NMOSD exhibited distinct GM pathologies, with cautious interpretation of the results due to study limitations.

Summary: The study investigated the role of FBXO7 gene mutations in Parkinson's disease and found that these mutations lead to a decrease in dopaminergic neurons and the formation of protein aggregates. They also discovered mitochondrial fragmentation in neuronal cells, suggesting that dysfunction in proteolytic and mitochondrial degradation systems plays a crucial role in the development of Parkinson's disease.

Summary: Leucine rich-repeat kinase 2 (LRRK2) is the most well-known genetic cause of familial Parkinson's disease (PD). Its functions and relationship to the pathogenesis of PD are not fully understood. Recent studies have suggested that LRRK2 plays a role in glial cell dysfunction and neurodegeneration, particularly in lysosomal dynamics and inflammation. This review discusses the proposed functions of LRRK2 in glial cells and its involvement in the pathomechanisms of PD.

Summary: This study aimed to investigate the impact of the COVID-19 pandemic on patients with Parkinson's disease and their caregivers in Japan. The results showed that over 40% of patients reduced their frequency of going out, approximately 7-30% experienced worsened symptoms, and caregivers reported increased burden. The findings suggest the importance of providing support to patients and caregivers during infectious disease epidemics to alleviate their burden.

Summary: Schwartz-Jampel syndrome (SJS) is a rare genetic disorder characterized by myotonia. In this study, a cellular model of SJS was created using patient-derived induced pluripotent stem cells, which showed hyper-responsiveness to acetylcholine. These findings confirmed the use of cellular models in studying SJS and evaluating myotonia in clinical cases.

Summary: This study compared the white matter differences between nonmedicated patients with early-stage GBA-PD and iPD using a novel technique, fixel-based analysis. The results showed that patients with GBA-PD had lower white matter density, while patients with iPD had larger white matter fiber bundles. These findings may be related to neurodegenerative diseases, α-synuclein accumulation, and cognitive and motor impairments.

Summary: The study analyzed the levels of different IgG subclasses in the blood of Japanese and Italian individuals with relapsing remitting multiple sclerosis (MS) in response to MAP-derived peptides. The study also examined the effects of MAP peptides on MOG-induced experimental autoimmune encephalomyelitis (EAE) in mice. The results suggest a potential link between MAP and the development or exacerbation of MS, particularly in individuals with elevated serum IgG4 levels.

Summary: The study found that approximately 29.1% of iNPH patients had comorbid PD/PDD, while about 10.1% had comorbid DLB. Comorbid PD/PDD or DLB showed significant differences in facial expansion and upper-limb parkinsonism. DaTscan and RT-QuIC can help differentiate these diseases and affect their clinical features.

Summary: This study investigated the protective effects and mechanisms of human placenta derived mesenchymal stem cells (hPMSCs) transplantation in a rat model of hypoxic-ischemic encephalopathy (HIE). The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.

Summary: GSDME plays a crucial role in the pathogenesis of Alzheimer's disease by regulating the switch from apoptosis to pyroptosis and participating in neuroinflammatory response. Knockdown of GSDME has been shown to improve cognitive impairments, indicating that GSDME could be a therapeutic target for Alzheimer's disease.
