Understanding host factors driving asymptomatic versus severe disease outcomes is of key importance if we are to control emerging and re-emerging viral infections. HLA-B*15:01 has been associated with asymptomatic SARS-CoV-2 infection in nonhospitalized individuals of European ancestry, with protective immunity attributed to preexisting cross-reactive CD8 T-cells directed against HLA-B*15:01-restricted Spike-derived S peptide (B15/SCD8 T-cells). However, fundamental questions remained on the abundance and clonotypic nature of CD8 T-cell responses in HLA-B*15:01-positive patients who succumbed to life-threatening COVID-19.

Emerging ferroptosis-immunotherapy strategies, integrating functionalized nanoplatforms with ferroptosis-inducing agents and immunomodulatory therapeutics, demonstrate significant potential in managing primary, recurrent, and metastatic malignancies. Mechanistically, ferroptosis induction not only directly eliminates tumor cells but also promotes immunogenic cell death (ICD), eliciting damage-associated molecular patterns (DAMPs) release to activate partial antitumor immunity. However, standalone ferroptosis therapy fails to initiate robust systemic antitumor immune responses due to inherent limitations: low tumor immunogenicity, immunosuppressive microenvironment constraints, and tumor microenvironment (TME)-associated physiological barriers (e.

The identification of phosphatases that dephosphorylate specific sites in proteins remains a major challenge, particularly for the major class of serine/threonine-specific phosphatases, which function as holoenzymes. Here, we report the development of synthetic trap-peptides to identify phosphatases that bind to Tom6, a subunit of the mitochondrial translocase of the outer membrane (TOM) complex. The TOM complex is regulated by reversible phosphorylation, and although responsible kinases have been identified, the corresponding phosphatases so far remain unknown.

Genetic variants (both coding and noncoding) can impact gene function and expression, driving disease mechanisms such as cancer progression. The systematic study of endogenous genetic variants is hindered by inefficient precision editing tools, combined with technical limitations in confidently linking genotypes to gene expression at single-cell resolution. We developed single-cell DNA-RNA sequencing (SDR-seq) to simultaneously profile up to 480 genomic DNA loci and genes in thousands of single cells, enabling accurate determination of coding and noncoding variant zygosity alongside associated gene expression changes.

Endoplasmic reticulum unfolded protein responses contribute to cancer development, with activating transcription factor 6 (ATF6) involved in microbiota-dependent tumorigenesis. Here we show the clinical relevance of ATF6 in individuals with early-onset and late colorectal cancer, and link ATF6 signalling to changes in lipid metabolism and intestinal microbiota. Transcriptional analysis in intestinal epithelial cells of ATF6 transgenic mice (nATF6) identifies bacteria-specific changes in cellular metabolism enriched for fatty acid biosynthesis.
