Ginsenoside Rg3 enriches SCFA-producing commensal bacteria to confer protection against enteric viral infection via the cGAS-STING-type I IFN axis

Rg3 elicits protection against local and systemic enteric virus infection by regulating the intestinal microbiome To assess the antiviral effects of Rg3 in vivo, groups of C57BL/6J mice (referred to as WT B6 hereafter) were orally administered Rg3 for 3 consecutive days, inoculated with MNV-1 by the peroral route, and…

The impact of mutational clonality in predicting the response to immune checkpoint inhibitors in advanced urothelial cancer

Genomic analysis and cohort description We generated whole-exome sequencing (WES) and RNA sequencing (RNA-Seq) data from tumors and blood samples from 27 advanced urothelial cancer patients treated with anti-PD-1/PD-L1 ICIs at Hospital del Mar (Fig. 1a). WES data was obtained from the tumors before treatment as well as from blood samples,…

Stable expression of large transgenes via the knock-in of an integrase-deficient lentivirus

CLIP enables high-efficiency knock-in into an essential locus To create CLIP, we leverage integrase-deficient lentiviruses (IDLV) to deliver an HDR donor template as a viral RNA genome to cells25,26. IDLV consists of lentiviral components but with a D64V mutation in the integrase, maintaining this enzyme’s ability to package and nuclear…

Specific recognition of an FGFR2 fusion by tumor infiltrating lymphocytes from a patient with metastatic cholangiocarcinoma

Introduction Cholangiocarcinoma (CC) is a form of gastrointestinal cancer that originates from the epithelium of either intrahepatic or extrahepatic bile ducts. It accounts for approximately 3% of all gastrointestinal cancers, with reported incidence of one to two cases per 100,000 persons per year in the USA (and much higher incidence…

G9a promotes immune suppression by targeting the Fbxw7/Notch pathway in glioma stem cells

Aim: Immunotherapy for glioblastoma multiforme (GBM) is limited because of a strongly immunosuppressive tumor microenvironment (TME). Remodeling the immune TME is an effective strategy to eliminate GBM immunotherapy resistance. Glioma stem cells (GSCs) are inherently resistant to chemotherapy and radiotherapy and involved in immune evasion mechanism. This study aimed to…

Different molecular pathways are disrupted in Pyoderma gangrenosum patients and are associated with the severity of the disease

Through a novel bioinformatic approach this study provided insights on the main biological pathways disrupted by genetic defects in a small cohort of unrelated PG patients. Specifically, we focused on the different pathways involved in “multilesional” and “unilesional” PG, using these groups as a proxy for disease severity.Both in the…
