Leukemia escapes immunity by imposing a Type-1 regulatory program on neoantigen-specific CD4+ T cells.

The significance of endogenous immune surveillance in acute lymphoblastic leukemia (ALL) remains controversial. Using clinical B-ALL samples and a novel mouse model, we show that neoantigen-specific CD4+ T cells are induced to adopt type-1 regulatory (Tr1) function in the leukemia microenvironment. Tr1s then inhibit cytotoxic CD8+ T cells, preventing effective leukemia clearance.

Analysis of high-molecular-weight proteins using MALDI-TOF MS and machine learning for the differentiation of clinically relevant Clostridioides difficile ribotypes.

Purpose: Clostridioides difficile is the main cause of antibiotic related diarrhea and some ribotypes (RT), such as RT027, RT181 or RT078, are considered high risk clones. A fast and reliable approach for C. difficile ribotyping is needed for a correct clinical approach.

Data on vascular plant species composition along two elevation gradients in the high Andes of central Chile (33°S).

The results of a survey of vascular plant species along two elevational gradients in the high Andes of central Chile (33°S) are reported. Vascular plant species were recorded in 12 and 15 plots of 1600 m set up to be permanent, distributed at intervals of 100 m elevation along two elevational gradients, one in the La Parva (2500-3600 m a.s.

Multicenter evaluation of Fourier transform infrared (FTIR) spectroscopy as a first-line typing tool for carbapenemase-producing in clinical settings.

Early use of infection control methods is critical for preventing the spread of antimicrobial resistance. Whole-genome sequencing (WGS) is considered the gold standard for investigating outbreaks; however, the turnaround time is usually too long for clinical decision-making and the method is also costly. The aim of this study was to evaluate the performance of Fourier transform infrared (FTIR) and artificial intelligence tools as a first-line typing tool for typing carbapenemase-producing (CPK) in the hospital setting.
