  Understanding the heterogeneity of the B cell response induced in autoimmune individuals is important for the development of therapies designed to target the cells underlying disease progression. Here the authors use a new mouse model of autoimmunity to assess the heterogeneity of the B cell response using single-cell RNA-sequencing and BCR-sequencing and found that these B cell responses are similar to those by exogenous protein immunization.

  This important study describes the protective role of group 2 innate lymphoid cells (ILC2s) in tissue physiology and contributes to immunity, inflammatory pathology, and metabolism in maintaining homeostasis during pregnancy. The authors provide convincing evidence that ILC2s have new roles distinct from parasite protection and allergy inducers. Uterine ILC2s are key immune cells during normal and complicated pregnancies.

  This paper will be of broad interest to immunologists that study T cell responses and formation of the peripheral T cell compartment. Using elegant live imaging approaches, the authors provide convincing evidence in support of a revised model for how positive-selected thymocytes are called to the thymus medulla to interact with distinct antigen-presenting cells. The work makes an important contribution to the field by identifying previously unappreciated complexities related to cellular movement during T cell generation.

  This study presents valuable findings on the changes of immune cell populations and stromal cells occurring at the CNS borders in a neonatal bacterial meningitis model, focusing on fibroblasts, macrophages and endothelial cells. The study provides solid snRNA-seq dataset and high quality immune fluorescence images of dissected brain border regions, that will be useful for the community. These observations and datasets will be of interest to the neuro-immunology community.

  Non-communicable diseases (NCDs) are rising rapidly in urbanizing populations in many parts of the developing world, including in sub-Saharan Africa. Temba and colleagues show important evidence that healthy Tanzanians display a pro-inflammatory phenotype with enrichment of specific immune-metabolic pathways. Dood-derived metabolites were identified as an important driver of inflammation-related molecules. These findings provide solid evidence that the dietary transition that occurs in urbanizing areas in sub-Saharan Africa may contribute significantly to the increased incidence of non communicable diseases in this part of the world.

  In this study, Li and al describe valuable insights into the mechanisms underlying sex-differences diet-induced obesity in mice, with a role of macrophage-derived RELMa secretion in female-specific protection. They provide solid evidence for the impact of RELMa signaling in eosinophil recruitment for diet-induced obesity protection in female mice. Single-cell RNA-seq analysis of the stromal vascular fraction of control and RELMa deficient animals methods were used to investigate molecular mechanisms underlying the protection as a powerful method, although the analysis of this data is difficult to evaluate with incomplete methodological information.
