The liver-resident immune cells (LrICs) determine the immune properties, but the unique composition and heterogeneity of these cells are incompletely understood. Here, we dissect the diversity of LrICs by a comprehensive transcriptomic profiling using the unbiased single-cell RNA-sequencing (scRNA-seq). A total of 70, 706 of CD45+ immune cells from the paired liver perfusion, spleen and peripheral blood as references were profiled. We identified more than 30 discrete cell populations comprising 13 of T and NK cell, 7 of B cell, 4 of plasma cell, and 8 of myeloid cell subsets in human liver and donor-paired spleen and blood, and characterized their tissue distribution, gene expression and functional modules. Especially, four of CXCR6+ T and NK cell subsets were found to be present preferentially in the liver, where they manifested heterogeneity, distinct function and prominent homeostatic proliferation. We propose a universal category system of T and NK cells based on distinct chemokine receptors, confirmed subsequently by phenotype, transcriptional factors and functionality. We also identified adaptive changes by the spleen and liver-derived monocyte and macrophage populations. Finally, we give a global glimpse on B cell and plasma cell subsets in human spleen and liver. We, therefore, reveal the heterogeneity and functional diversity of LrICs in human. This study presents comprehensively the landscape of LrICs and will enable further study on their roles in various human diseases. © The Author(s) 2020.In response to DNA damage, p53-mediated signaling is regulated by protein phosphorylation and ubiquitination to precisely control G2 checkpoint. Here we demonstrated that protein SUMOylation also engaged in regulation of p53-mediated G2 checkpoint. We found that G2 DNA damage suppressed SENP3 phosphorylation at G2/M phases in p53-dependent manner. We further found that the suppression of SENP3 phosphorylation was crucial for efficient DNA damage/p53-induced G2 checkpoint and G2 arrest. Mechanistically, we identified Cdh1, a subunit of APC/C complex, was a SUMOylated protein at G2/M phase. SENP3 could de-SUMOylate Cdh1. DNA damage/p53-induced suppression of SENP3 phosphorylation activated SENP3 de-SUMOylation of Cdh. De-SUMOylation promoted Cdh1 de-phosphorylation by phosphatase Cdc14B, and then activated APC/CCdh1 E3 ligase activity to ubiquitate and degrade Polo-like kinase 1 (Plk1) in process of G2 checkpoint. These data reveal that p53-mediated inhibition of SENP3 phosphorylation regulates the activation of Cdc14b-APC/CCdh1-Plk1 axis to control DNA damage-induced G2 checkpoint. © The Author(s) 2020.Background Autism spectrum disorder (ASD) is a neurodevelopmental disorder, mainly characterized by impairment of social communication and restricted interests. ASD is frequently accompanied by attention deficit hyperactivity disorder (ADHD), which is characterized by carelessness, hyperactivity and impulsivity (ASD/ADHD). It has been suggested that ASD and ADHD are associated with oxidative stress, that is, that patients with ASD/ADHD are in a state of increased oxidative stress. There are currenr tly no objective or biological test criteria for evaluating the efficacy of drug therapy in these patients. The purpose of this study was to evaluate whether oxidative stress markers [serum reactive oxygen metabolites (d-ROMs) levels and biological antioxidant potential (BAP)] can be used as objective indicators for evaluating the efficacy of drug treatment in ASD/ADHD patients. Methods The subjects of this study subjects were 50 Japanese patients with ASD/ADHD aged 4 to 14 years old. Serum samples were obtained fren. Conclusion Our results suggest the possibility that the serum level of d-ROMs may be useful as an objective assessment marker to supplement the subjective assessment of the effects of drug treatment in school-age children with ASD/ADHD. © The Author(s) 2020.A 32-year-old man initially received a diagnosis of Duchenne muscular dystrophy (DMD). Genetic analysis revealed two novel heterozygous FKRP variants c.169G>A (p.Glu57Lys) and c.692G>A (p.Trp231*).  https://www.selleckchem.com/products/OSI-906.html  These results indicated that the patient had limb-girdle muscular dystrophy type 2I (LGMD2I) caused by recessive FKRP variants. Patients with LGMD2I and DMD have many overlapping phenotypes. LGMD2I should be considered in patients who have a DMD phenotype but not a DMD pathogenic variant. © The Author(s) 2020.Fungal secondary metabolites are synthesized by complex biosynthetic pathways catalized by enzymes located in different subcellular compartments, thus requiring traffic of precursors and intermediates between them. The β-lactam antibiotics penicillin and cephalosporin C serve as an excellent model to understand the molecular mechanisms that control the subcellular localization of secondary metabolites biosynthetic enzymes. Optimal functioning of the β-lactam biosynthetic enzymes relies on a sophisticated temporal and spatial organization of the enzymes, the intermediates and the final products. The first and second enzymes of the penicillin pathway, ACV synthetase and IPN synthase, in Penicillium chrysogenum and Aspergillus nidulans are cytosolic. In contrast, the last two enzymes of the penicillin pathway, phenylacetyl-CoA ligase and isopenicillin N acyltransferase, are located in peroxisomes working as a tandem at their optimal pH that coincides with the peroxisomes pH.  https://www.selleckchem.com/products/OSI-906.html  Two MFS transporters, PenM and PaaT h. chrysogenum. The highly efficient secretion system that exports penicillin against a concentration gradient may involve active penicillin extrusion systems mediated by vesicles that fuse to the cell membrane. However, there is no correlation of pexophagy with penicillin or cephalosporin formation since inactivation of pexophagy leads to increased penicillin or cephalosporin biosynthesis due to preservation of peroxisomes. The penicillin biosynthesis finding shows that in order to increase biosynthesis of novel secondary metabolites it is essential to adequately target enzymes to organelles. © The Author(s) 2020.
