     This study presents an alternative to conventional and UV-based tetramers, which are easy to use and reliable for the identification of antigen-specific CD8 T cells. The authors demonstrate that tetramers for HLA alleles A0301, A1101, B0702, and C0702 can be subjected to specific temperatures that facilitate peptide exchange, whilst maintaining structural integrity. Whilst the strength of the evidence is currently incomplete, further development and validation of this approach is likely to provide a useful alternative to generating reagents for examining T cell specificities.

     This useful study shows a protective role of type 1 IFN during Mycobacterium tuberculosis infection. It shows that the type 1 IFN response in human skin TST inversely correlates with TB severity, suggesting its protective role. Considering that type I IFN is usually shown to be pro-pathogenic, the higher vulnerability of zebrafish larvae lacking stat2 to M marinum infection is a strong result. However, the conclusion that IFN-I is protective during mycobacterial infection remains indirect and incomplete; the study requires additional mechanistic insights and validation.

     Engineering of adeno-associated virus (AAV) replication proteins may provide new insights into Parvoviral replication. The authors created a useful collection of Rep protein variants with changes that alter the amino acid sequence, but these did not lead to clear improvements in how the virus worked. Instead, their screen showed that changes that do not alter the protein ("synonymous" mutations) and changes to the promoter were more common. As it stands the results are incomplete due to potential issues with the screening design. We encourage a more complete characterization, which may enhance the translational potential of the approach.

     Endothelial cell-specific loss of TGF-beta signaling in mice leads to CNS vascular defects, specifically impairing retinal development and promoting immune cell infiltration. The data are solid, showing that loss of TGF-beta signaling triggers vascular inflammation and attracts immune cells specific to CNS vasculature, but there are issues with the single-nucleus RNA sequencing of immune cells. These findings are valuable, highlighting TGF-beta's role in maintaining vascular-immune homeostasis and its therapeutic potential in neurovascular inflammatory diseases.

     This study presents an important finding linking the bacterial metabolite trimethylamine and its receptor to circadian rhythms and olfaction. The current evidence supporting the claims of the authors is convincing, although further data and improvements to the presentation would further increase the impact of these results. This work will be of broad interest to researchers interested in nutrition, microbial metabolism, circadian rhythms, and host-microbiome interactions.

     This valuable study addresses the role of sphingolipid metabolism in maintaining endolysosomal membrane integrity and its impact on tau pathology in Caenorhabditis elegans and human cell culture models. The methods are solid and the proposed mechanisms are conceivable. However, the current evidence is incomplete and could be strengthened, due to reliance on imaging data and insufficient biochemical validation. The work will be of broad interest to cell biologists and biologists working on Alzheimer's disease and related proteinopathies.

     This important study provides converging results from complementary neuroimaging and behavioral experiments to identify human brain regions involved in representing regular geometric shapes. Geometric shape concepts are universally present across diverse human cultures and possibly essential for unique human capabilities such as numerical cognition and symbolic reasoning, and identifying the brain networks involved in geometric shape representation is of broad interest to researchers studying human visual perception, reasoning, and cognitive development. The provided experimental evidence regarding the presence of geometric shape regularity representation in dorsal parietal and prefrontal cortex is solid, but the claimed link with mathematical reasoning, the influence of experimental tasks, and the role of experience in driving geometric shape representation in both humans and artificial vision models require further elucidation.

     This study identifies 53BP1 as an interaction partner of GMCL1 (a likely CUL3 substrate receptor). The study seeks to link this finding to regulation of the mitotic surveillance pathway and paclitaxel resistance in cancer. The evidence for these claims is currently inadequate; concerns include the use of cell lines that have been reported to lack the mitotic surveillance pathway, insufficient consideration of paclitaxel mechanisms of action, and an overinterpretation of correlative results.

      This study presents valuable findings that advance our understanding of mural cell dynamics and vascular pathology in a zebrafish model of cerebral small vessel disease. The authors provide compelling evidence that partial loss of foxf2 function leads to progressive, cell-intrinsic defects in pericytes and associated endothelial abnormalities across the lifespan, leveraging powerful in vivo imaging and genetic tools. The strength of evidence could be further improved by additional mechanistic insight and quantitative or lineage-tracing analyses to clarify how pericyte number and identity are affected in the mutant model.
