  This important study shows that the Nora virus, a natural Drosophila pathogen that also persistently infects many laboratory fly stocks, infects intestinal stem cells (ISCs), leading to a shorter life span and increased sensitivity to intestinal infection with the Pseudomonas bacterium. The authors provide convincing data to support their conclusions. The paper provides new insights into virus-host interactions in the Drosophila gut and serves as a warning for scientists who use the fruit fly as a model to study gut physiology.

• Curated by eLife

  eLife Assessment

  This study introduces a useful toolkit for zebrafish transgenesis, significantly enhancing the flexibility and efficiency of transgene generation for immunological applications. The authors provide supporting evidence through well-designed experiments, demonstrating the toolkit's utility in generating diverse and functional transgenic lines. While the findings are solid, additional functional validation and broader comparisons to existing systems would strengthen the overall evidence base and ensure broader relevance to the zebrafish field, thereby increasing the significance of the study.

  This important study utilizes humanized mice, in which human immune cells are introduced into immune-deficient mice, to provide convincing evidence that two helper CD4 T-cell subsets, T-follicular helper (Tfh) and T-peripheral helper (Tph) cells, are able to drive both autoantibody production and induction of autoimmunity. The work will be of broad interest to medical scientists engaged in deciphering how human immune cells mediate immune responses and contribute to the development of autoimmune diseases.

  Catani and colleagues provide data on antigenic properties of neuraminidase proteins of pandemic H1N1 and show that antigenic diversity of the neuraminidase from 2009 to 2020 largely falls into two groups. These antigenic groups map to two phylogenetic groups, and substitutions at positions 432 and 321 are likely associated with the antigenic change. These data and results allow useful insights into the antigenic properties of N1 influenza and the evidence supporting the conclusions is solid.

  This valuable manuscript presents a potentially novel mechanism by which the phospholipid scramblase, PLSCR1, defends against influenza A virus infection. The paper was based on solid findings involving knockout and lung-specific over-expressing Plscr1 mice, airway tissue expression, and mechanistic studies to show Plscr1 enhances type III interferon-mediated viral clearance. The study is extensive and overall well performed.
