The paper identifies mechanisms that limit Ku protein accumulation in chromatin, showing DNA-PKcs blocks Ku entry, and two additional mechanisms restrict Ku levels in the absence of DNA-PKcs.

This paper introduces a multimodal imaging workflow combining MALDI-MSI and IF microscopy to enhance spatial single-cell metabolomics, validated on mouse spleen sections.

This study uses human airway organoids to model tuberculosis infection, showing mycobacteria infect epithelial cells with low efficiency and the organoid microenvironment controls but does not eliminate the pathogen.
