Downregulation of RSAD2 ameliorates keratinocyte hyperproliferation and skin inflammation in psoriasis via the TAK1/NF-κB axis.

Immune cell infiltration and keratinocyte (KC) hyperproliferation are characteristics of psoriasis. Radical S-adenosyl methionine domain-containing 2 (RSAD2) plays an integral role in the innate immune response and is associated with various immune-related diseases. However, RSAD2's expression and role in modulating immune responses in psoriasis remain unexplored.

Oral resists the acidic pH of the stomach due to membrane erucic acid synthesized via enoyl-CoA hydratase-related protein FnFabM.

Background And Objective: Oral bacteria can translocate to the intestine, and their colonization efficiency is influenced by the gastrointestinal tract pH. Understanding how oral bacteria resist acidic environments is crucial for elucidating their role in gut health and disease.

Methods: To investigate the mechanisms of acid resistance in oral bacteria, an in vitro gastrointestinal tract Dynamic pH Model was established.

Integrative multi-omics analysis reveals liver-gut axis adaptation in high-altitude goats.

The liver-gut axis is an important regulatory axis for the host's metabolic functions. The study of liver gene expression, changes in metabolic products and the regulation of gut microbial communities in plateau animals under harsh environments can reveal the mechanisms by which Tibetan goats adapt to the plateau environment. This study employs transcriptome, metabolome and metagenomic analyses to reveal the differences in genes, metabolism, and gut microbiota between Jianzhou big-eared goats (JBG) and Xizang cashmere goats (TCG), which is of significant importance for improving survival models of high-altitude ruminants.

Discovery of a common light chain bispecific antibody targeting PD-1 and PD-L1 by Hybridoma-to-Phage-to-Yeast (H2PtY) platform.

Background: Therapeutic antibody drugs targeting the PD-1 pathway are generally characterized by relatively low response rates and susceptibility to drug resistance during clinical application. Therefore, there is an urgent need for alternative therapeutic strategies to increase the immune response rate. Bispecific antibodies co-targeting PD-1 and PD-L1 may have greater potential to improve the efficacy of the immune checkpoint pathway.

A Randomized, Comparative Trial of a Potassium-Competitive Acid Blocker (X842) and Lansoprazole for the Treatment of Patients with Erosive Esophagitis.

Introduction: X842 is a new type of gastric acid-suppressing agent with a rapid onset of action and a long duration of effect. We aim to investigate the efficacy and safety of different doses of X842 versus lansoprazole in the treatment of patients with erosive esophagitis (EE).

Methods: This phase 2 study included 90 patients with EE (Los Angeles grades A-D) who were randomized (1:1:1) to receive oral low-dose X842 (50 mg/day, n=31), high-dose X842 (100 mg/day, n=31), or lansoprazole (30 mg/day, n=30) for 4 weeks.
