Summary: This study found that vacuolar protein-sorting protein (VPS) may play an important role in the development of Alzheimer's disease (AD), and targeting VPS26 and VPS35 for treatment may help delay the onset of cognitive decline.

Summary: It was found that knocking out vps10, vps13, and vps21 genes in T. reesei improved cellulase production by alleviating vacuolar transport and degradation. Transcriptome analysis indicated that increased cellulase gene expression might be attributed to the differential expression of sugar transporters. This study provides new clues for higher cellulase production in T. reesei through the alleviation of vacuolar transport via knockout of vps10, vps13, and vps21.

Summary: In Arabidopsis, vacuolar sorting receptor isoform 1 (VSR1) plays a key role in directing 12S globulins and other storage proteins to the protein storage vacuoles during seed development. The crystal structure of VSR1-PA in complex with the C-terminal pentapeptide of cruciferin 1 sheds light on the molecular mechanisms involved in the sorting process. The study provides insights into how VSR1 recognizes and interacts with the C-terminal sorting determinants of various storage proteins, which could potentially aid in targeting recombinant proteins to seed storage vacuoles.

Summary: This study established a DC-based therapeutic approach using CRISPR/Cas9-mediated targeted gene disruption to alleviate allergic reactions associated with allergic rhinitis. Targeting VPS37A/B enabled reduction of Th2 cytokine production and alleviation of AR-related symptoms in mouse models, providing a promising strategy for treating allergic diseases.

Summary: In this study, a partial sequence of Eimeria tenella VPS29 (EtVPS29) was cloned and expressed. It was found that EtVPS29 was widely distributed in the cytoplasm of E. tenella sporozoites and showed a protective effect against E. tenella infection in chickens.

Summary: In this study, significant overexpression of 28 VPSs in hepatocellular carcinoma (HCC) tissues compared to normal tissues was observed. The expression of VPSs showed a negative correlation with overall survival, while displaying a positive correlation with tumor grade and stage. VPS72 was identified as a potential independent risk factor for HCC prognosis, and its overexpression was associated with poor prognosis factors and immune cell infiltration levels.

Summary: Lysosome is a crucial catabolic organelle in cells, with mutations in lysosomal proteins potentially leading to neurodegeneration, cancer, and age-related diseases. The vacuole serves as a lysosomal analog in Saccharomyces cerevisiae, containing evolutionarily conserved proteins. Proteins can reach vacuoles through different pathways, including the Vps10-dependent endosomal vacuolar protein sorting pathway, the alkaline phosphatase pathway, and the cytosol-to-vacuole transport pathway.

Summary: The vacuole of Candida albicans is involved in various processes such as homeostasis control, cellular trafficking, dimorphic switching, and stress tolerance. Factors like V-ATPases and VPS are crucial for pH balance and filamentation, while vacuolar calcium exchange systems like Yvc1 and Pmc1 play a role in maintaining cytosolic calcium levels and are influenced by V-ATPases function. These proteins collectively contribute to the virulence and pathogenesis of C. albicans infections.

Summary: Alzheimer's disease is a common neurodegenerative disease associated with pathological autophagy-lysosomal pathway dysfunction. Dexmedetomidine has been suggested as an adjuvant to general anesthesia, with advantages in reducing postoperative cognitive dysfunction. However, there is limited evidence on the effects of Dex on neuronal autophagy dysfunction in Alzheimer's disease models.

Summary: VPS10P domain receptors play a crucial role in psychiatric and neurodegenerative diseases. The study revealed distinct temporal, spatial, and subcellular expression patterns of different receptor species in the human brain. This provides valuable insights into the impact of receptor function on behavioral and cognitive defects in the human brain.

Summary: Bombyx mori is a protein-rich source of food that has gained renewed interest as a potential alternative protein source. In this study, the vps4 gene was interfered using siRNA in H2S-treated silkworms, resulting in decreased body weight, cocoon weight, cocoon shell weight, and egg laying and production. H2S treatment alleviated the inhibition caused by vps4 gene knockdown, except for egg laying and production. siRNA interference led to reduced expression of the targeted vps4 gene, with the greatest effect observed with vps4-2 siRNA. These findings highlight the significant phenotypic and genotypic effects of vps4 gene knockdown in silkworms, which is important for future research.
