  The authors developed a fundamental computational method, which is intended to automatically process bioluminescence imaging-derived tumour images across anatomical regions and over time. This allows quantitative analysis of such data, and the authors applied it to describe the spatiotemporal distribution of tumour cells in response to CD19-targeted CAR-T cells that contained either CD28 or 4-1BB costimulatory domains. Some operational limitations were identified, which relate to the pipeline's reliance on predefined regions of interest instead of aligning signal sites with anatomical information, scaling, and limitations in taking animal pose into account. Overall, the authors provide compelling evidence for the functionality of their computational approach towards automated analysis of bioluminescence imaging data, while applying it to a current topic of wide interest in cell therapy research.

  In this manuscript, Jong et al. provide and validate a very useful resource for performing CRISPR screenings to study neutrophil differentiation and function by generating Hoxb8 cells that constitutively express Cas9. This library-screening approach has the potential to improve on the established lentiviral CRISPR-Cas9 editing of Hoxb8 cells. However, the technical advances provided are only incremental and the results presented in this study do not significantly further our understanding of these cells, but rather provide a good validation of their Cas9+ modified version.

  In their study, Scherer and colleagues aim to use analyses of single-cell clones of murine granulocyte monocyte progenitors that are conditionally immortalized, and analyses of neutrophils derived from those clones to characterize an experimental system for studying neutrophil heterogeneity. The multi-omic and functional analyses reported are valuable but the strength of the evidence presented in support of them is incomplete because the study lacks a rigorous demonstration that the neutrophil-like cells that they derive are fully mature neutrophils.

  This study presents valuable data suggesting that ATP-induced modulation of alveolar macrophage (AM) functions is associated with NLRP3 inflammasome activation and enhanced phagocytic capacity. While the in vivo and in vitro data reveal an interesting phenotype, the evidence provided is incomplete and does not fully support the paper's conclusions. Additional investigations would be of value in complementing the data and strengthening the interpretation of the results. This study should be of interest to immunologists and the mucosal immunity community.

  IL21R, being a key cytokine receptor for shaping the T follicular helper and B cell functions, utilizes two STAT family members, STAT1 and STAT3. The authors utilize the IL21R ENU-induced mutant, together with relevant in vitro and in vivo experiments, to dissect the function of STAT1 and STAT3. The approach by itself sounds reasonable, but the main conclusions are incompletely supported by the data presented in this manuscript.

  This valuable study highlights the key role of NK cells and PD-L1+ neutrophils in worsening sepsis responses in the context of MASH (metabolic dysfunction-associated steatohepatitis). It focused on the role of neutrophils in mediating this effect, which is based on a choline-deficient high-fat diet model of various knockouts or selective ablation of immune cell types. While the data presented are of great interest, there are concerns around the reliability of the strength of the evidence provided, which is currently considered incomplete. The study may be of interest to researchers in immunopathological disease mechanisms once confirmatory studies have been completed.

  [Editors' note: the authors no longer have access to the original flow cytometry data and plan to compile new datasets in the future.]
