Primary sclerosing cholangitis (PSC) is an idiopathic, progressive and incurable liver disease. Here, we aimed for systematic analyses of adaptive immune responses in PSC. By profiling the T cell repertoires of 504 individuals with PSC and 904 healthy controls, we identified 1,008 clonotypes associated with PSC. A substantial fraction of these clonotypes was restricted to known PSC human leukocyte antigen susceptibility alleles and known to target Epstein-Barr virus (EBV) epitopes. We further utilized phage-immunoprecipitation sequencing to determine antibody epitope repertoires of 120 individuals with PSC and 202 healthy controls, which showed a higher burden of anti-EBV responses in PSC than controls. EBV-specific monoclonal antibodies isolated from B cells in PSC livers corroborated convergent B and T cell responses against EBV. By analyzing electronic health records of >116 million people, we identified an association between infectious mononucleosis and PSC (odds ratio, 12; 95% confidence interval, 6.3-22.9), suggesting a link between EBV and PSC.

Background: Few data are available on the impact of primary sclerosing cholangitis (PSC) on inflammatory bowel disease (IBD).
Objective: We conducted a retrospective study using TriNetX to compare the outcomes of patients with IBD and those with concomitant IBD and PSC.
Methods: All patients with a confirmed diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or indeterminate colitis with or without PSC were eligible.

Establishing a low-resistance perovskite/ITO contact using self-assembled molecules (SAMs) is crucial for efficient hole transport in perovskite solar cells (PSCs) without a pre-deposited hole-transporting layer. However, SAMs at the buried interface often encounter issues like nonuniform distribution and molecular aggregation during the extrusion process, leading to significant energy loss. Herein, a molecular hybrid bridging strategy by incorporating a novel small molecule is proposed, (2-aminothiazole-4-yl)acetic acid (ATAA), featuring a thiazole ring and carboxylic acid group, along with the commonly used SAM, 4-(2,7-dibromo-9,9-dimethylacridin-10(9H)-yl)butyl)phosphonic acid (DMAcPA), into the perovskite precursor to synergistically optimize the buried interface.

Perovskite solar cells (PSCs) are rapidly advancing due to their high power conversion efficiencies (PCEs) and low fabrication costs. However, their commercialization is hindered by lead toxicity and the use of expensive materials, such as Spiro-OMeTAD and gold electrodes. This study presents a comprehensive SCAPS-1D simulation-based analysis of 14 perovskite absorber materials, spanning both Pb-based and lead-free compounds, under a unified device architecture using low-cost, nontoxic components: ZnO as the electron transport material (ETM), PEDOT:PSS + WO as a dual hole transport material, and nickel as the back contact.

In particular, ALD-processed SnO has demonstrated great potential as an electron transport layer in flexible perovskite solar cells (PSCs) and tandem modules. However, the poor electrical conductivities and surface wettabilities of amorphous SnO remain critical challenges for commercialization.

The characteristic pathological change in chronic pancreatitis (CP) is pancreatic fibrosis. In the early stages of CP development, injured acinar cells induce the infiltration of inflammatory cells, followed by pancreatic stellate cell (PSC) activation. Activated PSC induce the deposition of extracellular matrix (ECM) and promote the development of pancreatic fibrosis.
