Molecular subtypes explain lupus epigenomic heterogeneity unveiling new regulatory genetic risk variants.

The heterogeneity of systemic lupus erythematosus (SLE) can be explained by epigenetic alterations that disrupt transcriptional programs mediating environmental and genetic risk. This study evaluated the epigenetic contribution to SLE heterogeneity considering molecular and serological subtypes, genetics and transcriptional status, followed by drug target discovery. We performed a stratified epigenome-wide association studies of whole blood DNA methylation from 213 SLE patients and 221 controls.

RGS1 Modulates Autophagic and Metabolic Programs and Is a Critical Mediator of Human Regulatory T Cell Function.

Regulatory T cells (Tregs) are critical mediators of immune tolerance and play a diametric role in cancer and autoimmunity. Tumor-infiltrating Tregs are often associated with poor prognosis in solid tumors because their enrichment in the tumor microenvironment contributes to immunosuppression. Conversely, dysregulation in the Treg compartment can disrupt self-tolerance, leading to autoimmunity.

Structural, Hirshfeld surface and three-dimensional inter-action energy studies of 2-(6-iodo-4-oxo-3,4-di-hydro-quinazolin-3-yl)ethane-sulfonyl fluoride.

In the crystal, mol-ecules of the title compound, CHFINOS, are connected through C-H⋯N and C-H⋯O hydrogen bonds, I⋯O halogen bonds, π-π stacking inter-actions between the benzene and pyrimidine rings, and edge-to-edge electrostatic inter-actions, as shown by the analysis of the Hirshfeld surface and two-dimensional fingerprint plots, as well as inter-molecular inter-action energies calculated using the electron-density model at the HF/3-21 G level of theory.

Cellular mechanisms and effects of IL-4 receptor blockade in experimental conjunctivitis evoked by skin inflammation.

Ocular surface diseases, including conjunctivitis, are recognized as common comorbidities in atopic dermatitis (AD) and occur at an increased frequency in patients with AD treated with biologics targeting IL-4 receptor α (IL-4Rα) or IL-13. However, the inflammatory mechanisms underlying this pathology are unknown. Here, we developed a potentially novel mouse model of skin inflammation-evoked conjunctivitis and showed that it is dependent on CD4+ T cells and basophils.

Identifying barriers, facilitators, and interventions to support healthy eating in pregnant women with or at risk for hypertensive disorders of pregnancy.

Background: Heart-healthy diets are important in the prevention and treatment of hypertension (HTN), including among pregnant women. Yet, the barriers, facilitators, and beliefs/preferences regarding healthy eating are not well described in this population.

Objective: To identify barriers and facilitators to healthy diet, examine the prevalence of food insecurity, and determine interest in specific healthy diet interventions.
