IL1RAP Blockade With a Monoclonal Antibody Reduces Cardiac Inflammation and Preserves Heart Function in Viral and Autoimmune Myocarditis.

Background: Currently, there are no therapies targeting specific pathogenic pathways in myocarditis. IL (interleukin)-1 blockade has shown promise in preclinical studies and case reports. We hypothesized that blockade of IL1RAP (IL-1 receptor accessory protein), a shared subunit of the IL-1, IL-33, and IL-36 receptors, could be more efficient than IL-1 blockade alone.

Biomarkers for Prediction of Alcohol-Related Liver Cirrhosis: A General Population-Based Swedish Study of 537,250 Individuals.

Background And Aims: The study sought to examine which biomarkers have the best predictive capabilities for future alcohol-related liver cirrhosis (ARLC) in a general population setting.

Method: This population-based cohort study includes approximately 35% of the inhabitants of Stockholm County who had left a blood sample at an outpatient visit in primary care or occupational health screening from 1985 to 1996. All subjects with a blood sample measurement of alanine aminotransferase and aspartate aminotransferase (AST) were included, exclusions were made for persons with known liver disease.

Short-term S100A8/A9 Blockade Promotes Cardiac Neovascularization after Myocardial Infarction.

Acute-phase inhibition of the pro-inflammatory alarmin S100A8/A9 improves cardiac function post-myocardial infarction (MI), but the mechanisms underlying the long-term benefits of this short-term treatment remain to be elucidated. Here, we assessed the effects of S100A8/A9 blockade with the small-molecule inhibitor ABR-238901 on myocardial neovascularization in mice with induced MI. The treatment significantly reduced S100A9 and increased neovascularization in the myocardium, assessed by CD31 staining.

The effect of axial length on pseudophakic retinal detachment.

Purpose: The purpose of the study was to analyse the surgical management and outcome regarding axial length in the population affected by pseudophakic retinal detachment (PRD) 2015-2020.

Method: The patients included were from an observational cohort study of patients undergoing cataract surgery in the region of Skåne during 2015-2017. Data were retrieved from the Swedish National Cataract Register and cross-referenced with cases of PRD in the same region from 2015 to 2020.

Interleukin-1 receptor accessory protein blockade limits the development of atherosclerosis and reduces plaque inflammation.

Aims: The interleukin-1 receptor accessory protein (IL1RAP) is a co-receptor required for signalling through the IL-1, IL-33, and IL-36 receptors. Using a novel anti-IL1RAP-blocking antibody, we investigated the role of IL1RAP in atherosclerosis.

Methods And Results: Single-cell RNA sequencing data from human atherosclerotic plaques revealed the expression of IL1RAP and several IL1RAP-related cytokines and receptors, including IL1B and IL33.
