A single-cell atlas of intestinal immune cells across the day-night cycle reveals dynamic populations https://www.biorxiv.org/content/10.64898/2026.01.24.701519v1

We built a containerised workflow that handles QC, doublet detection, CITE‑seq for scRNA‑seq data, and outputs a ready‑to‑use #Seurat object. One command, #reproducible results—ideal for labs without dedicated bioinformatics support.

Our new pre‑print is out!

The protein and mRNA abundance voronoi diagrams offer remarkably different perspectives.

Each tile in the maps represents a gene product; its size is proportional to the fraction of the gene product in hepatocytes.

USP2 inhibition unleashes CD47-restrained phagocytosis and enhances anti-tumor immunity | Nature Communications The CD47/SIRPα axis conveys a ‘don’t eat me’ signal, thereby thwarting the phagocytic clearance of tumor cells. Although blocking antibodies targeting CD47 have demonstrated promising anti-tumor effects in preclinical models, clinical trials involving human cancer patients have not yielded ideal results. Exploring the regulatory mechanisms of CD47 is imperative for devising more efficacious combinational therapies. Here, we report that inhibiting USP2 prompts CD47 degradation and reshapes the tumor microenvironment (TME), thereby enhancing anti-PD-1 immunotherapy. Mechanistically, USP2 interacts with CD47, stabilizing it through deubiquitination. USP2 inhibition destabilizes CD47, thereby boosting macrophage phagocytosis. Single-cell RNA sequencing shows USP2 inhibition reprograms TME, evidenced by increasing M1 macrophages and CD8+ T cells while reducing M2 macrophages. Combining ML364 with anti-PD-1 reduces tumor burden in mouse models. Clinically, low USP2 expression predicts a bett

USP2 inhibition leads to CD47 degradation, boosting phagocytosis and anti-tumor immunity. Novel therapeutic avenue—improves on previous antibody trials! PMID:40379682, Nat Commun 2025, @NatureComms https://doi.org/10.1038/s41467-025-59621-5 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪

A tissue-specific atlas of protein–protein associations enables prioritization of candidate disease genes - Nature Biotechnology Protein–protein interactions specific to 11 individual tissues are presented in a comprehensive resource.

Our work on deriving protein-protein (functional) associations across different human tissues from proteomics data is now published. There is quite a lot in this paper, so I will just touch on a few highlights:

Temporally discordant chromatin accessibility and DNA demethylation define short- and long-term enhancer regulation during cell fate specification Guerin et al. present a highly resolved timeline of chromatin and DNA methylation dynamics during early neural progenitor cell differentiation. Their approach demonstrates that chromatin and DNA methylation mechanisms operate on different timescales to mediate short- and long-term gene enhancer regulation.
