An increasing number of studies have recently indicated the important effects of gut microbes on various functions of the central nervous system.However, the underlying mechanisms by which gut microbiota regulate brain functions and behavioral phenotypes remain largely unknown. We therefore used isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomic analysis to obtain proteomic profiles of the hippocampus in germ-free (GF), colonized GF, and specific pathogen-free (SPF) mice. We then integrated the resulting proteomic data with previously reported mRNA microarray data, to further explore the effects of gut microbes on host brain functions. We identified that 61 proteins were upregulated and 242 proteins were downregulated in GF mice compared with SPF mice. Of these, 124 proteins were significantly restored following gut microbiota colonization. Bioinformatic analysis of these significant proteins indicated that the glucocorticoid receptor signaling pathway and inflammation-related pathways were the most enriched disrupted pathways. This study provides new insights into the pathological mechanisms of gut microbiota-regulated diseases.

Objective:To investigate clinical efficacy of narrow-band ultraviolet B (NB-UVB) irradiation around vitiliginous lesions in the treatment of refractory vitiligo.Methods:A total of 126 patients with refractory vitiligo were retrospectively collected from Department of Dermatology, the First Affiliated Hospital of Nanjing Medical University from June 2019 to November 2020. The patients were treated with NB-UVB irradiation around vitiliginous lesions after partial covering (perilesional irradiation group) , or conventional NB-UVB irradiation (conventional irradiation group) , twice a week for 3 consecutive months. After the treatment, the efficacy was evaluated. By using the propensity score method, the lesions in the 2 groups were matched at a ratio of 1∶1. Univariate and multivariate logistic regression analyses and stratified analysis were used to analyze the clinical efficacy of NB-UVB irradiation around vitiliginous lesions in the treatment of refractory vitiligo.Results:Totally, there were 420 skin lesions in the perilesional irradiation group and 257 in the conventional irradiation group, and 190 lesions were enrolled into each group by propensity-score matching. Before and after the matching, the response rates were both significantly higher in the perilesional irradiation group (71.9%, 67.9%, respectively) than in the conventional irradiation group (31.9%, 30.0%, respectively, both P < 0.05) . After the propensity-score matching, both univariate and multivariate logistic regression analyses showed significant differences in the efficacy between the perilesional irradiation group and conventional irradiation group ( OR = 4.9, 95% CI: 3.2, 7.6, P < 0.001; OR = 12.0, 95% CI: 6.5, 22.3, P < 0.001, respectively) . Vitiliginous lesions were classified according to hair types and irradiation methods: before the matching, there were 187 vitiliginous lesions with white hairs treated with the conventional irradiation and 246 treated with the perilesional irradiation, and there were 70 vitiliginous lesions with black hairs treated with the conventional irradiation and 174 treated with the perilesional irradiation; after the matching, 140 vitiliginous lesions with white hairs and 50 with black hairs were enrolled into each radiation group. Stratified analysis showed that the response rates of vitiliginous lesions with white hairs were significantly higher in the perilesional irradiation group (77.6%, 72.8%, respectively) than in the conventional irradiation group before and after the matching (19.3%, 20.7%, respectively, both P < 0.01) ; for the vitiliginous lesions with black hairs, there was no significant difference in the response rate between the 2 groups ( P = 0.908) . Conclusion:The efficacy of NB-UVB irradiation around vitiliginous lesions is superior to the conventional irradiation in the treatment of refractory vitiligo, especially vitiliginous lesions with white hairs.

G protein-coupled receptors (GPCRs) are involved in all human physiological systems where they are responsible for transducing extracellular signals into cells. GPCRs signal in response to a diverse array of stimuli including light, hormones, and lipids, where these signals affect downstream cascades to impact both health and disease states. Yet, despite their importance as therapeutic targets, detailed molecular structures of only 30 GPCRs have been determined to date. A key challenge to their structure determination is adequate protein expression. Here we report the quantification of protein expression in an insect cell expression system for all 826 human GPCRs using two different fusion constructs. Expression characteristics are analyzed in aggregate and among each of the five distinct subfamilies. These data can be used to identify trends related to GPCR expression between different fusion constructs and between different GPCR families, and to prioritize lead candidates for future structure determination feasibility.
