Sushi, von Willebrand factor type A, EGF and pentraxin domain containing 1 (SVEP1) is an extracellular matrix protein that causally promotes vascular disease and associates with platelet reactivity in humans. Here, using a human genomic and proteomic approach, we identify a high affinity, disease-relevant, and potentially targetable interaction between SVEP1 and the orphan receptor Platelet and Endothelial Aggregation Receptor 1 (PEAR1). This interaction promotes PEAR1 phosphorylation and disease associated AKT/mTOR signaling in vascular cells and platelets. Mice lacking SVEP1 have reduced platelet activation, and exogenous SVEP1 induces PEAR1-dependent activation of platelets. SVEP1 and PEAR1 causally and concordantly relate to platelet phenotypes and cardiovascular disease in humans, as determined by Mendelian Randomization. Targeting this receptor-ligand interaction may be a viable therapeutic strategy to treat or prevent cardiovascular and thrombotic disease.

Introduction: Retinoic acid receptor-related orphan receptor gamma t (RORγt) is a crucial transcription factor regulating Th17 cells, which secrete the cytokine IL-17. RORγt inhibitors are regarded as a therapeutic modality in a wide range of autoimmunity including psoriasis.
Objectives: The objective of the study is to investigate novel RORγt inhibitors from natural products (NPs), combining machine learning (ML)-based virtual screening, chemotaxonomic analysis, molecular docking, and molecular dynamics simulations, and biological validation.

Current research indicates that insulin secretion deficiency in β-cells contributes to Type 2 diabetes mellitus (T2DM), which is associated with neuropeptide Y receptor (Npy1r) overexpression from neuropeptide Y (NPY) system dysregulation. To date, limited literature has explored nobiletin (NOB) as a circadian modulator for restoring β-cell function through Npy1r regulation. This study investigates NOB's stimulatory effects on insulin secretion via Npy1r and clock-modulatory signaling to elucidate its underlying mechanism.

Ethanolamine signaling through the transmembrane quorum-sensing receptor CqsR influences Vibrio cholerae niche recognition and host colonization. In this study, we present a comprehensive structure-function analysis of CqsR. Specifically, we have determined X-ray crystal structures of the CqsR periplasmic domain bound to the signaling agonist ethanolamine and its analogs, serinol and L-alaninol, as well as the ligand-free (apo) form of CqsR.

In vitro studies have implicated orphan receptor GPRC5B in β-cell survival, proliferation and insulin secretion, but its relevance for glucose homeostasis in vivo is largely unknown. Using tamoxifen-inducible, β-cell-specific GPRC5B knockout mice (Ins-G5b-KOs) we show here that loss of GPRC5B does not affect β-cell function in the lean state, but results in strongly reduced insulin secretion and disturbed glucose tolerance in mice subjected to high fat diet for 16 weeks. Flow cytometry and single-cell expression analyses in islets from obese mice show a reduced β-cell abundance and a less mature β-cell phenotype in Ins-G5b-KOs.

The etiology of complex diseases such as metabolic-associated steatohepatitis (MASH) presents significant challenges for therapeutic discovery. Here, we developed ComplexDnet, a transcriptome- and network-integrated framework to prioritize disease-relevant targets. Applied across eight cancer types, ComplexDnet achieved an average recall of 77.
