Innate immunity: Alarmins rewire innate immunity in newborns
This study describes an important role for the endogenous alarmins S100A8 and S100A9 in protecting newborn infants from sepsis. Healthy newborns produce extremely high levels of S100 alarmins for the first five days of life; the authors found that these alarmins signal through TLR4 to (Source: Nature Reviews Immunology)

Asthma and allergy: Vitamin D primes neonatal immune system
Nature Reviews Immunology 17, 467 (2017). doi:10.1038/nri.2017.82 Author: Yvonne Bordon Vitamin D deficiency during pregnancy has been linked to the development of childhood asthma, but most studies in this area have been observational. To directly examine how vitamin D status in pregnancy affects the neonatal immune system, Hornsby et al. analysed cord blood samples (Source: Nature Reviews Immunology)

The theory of disappearing microbiota and the epidemics of chronic diseases
Nature Reviews Immunology 17, 461 (2017). doi:10.1038/nri.2017.77 Author: Martin J. Blaser In recent decades, the incidence of many apparently unrelated chronic diseases has markedly increased. Here, I theorize that losses of particular bacterial species of our ancestral microbiota have altered the context in which immunological, metabolic and cognitive development occur in early life, which results in (Source: Nature Reviews Immunology)

Cytoskeletal control of B cell responses to antigens
Nature Reviews Immunology 17, 621 (2017). doi:10.1038/nri.2017.67 Author: Pavel Tolar The actin cytoskeleton is essential for cell mechanics and has increasingly been implicated in the regulation of cell signalling. In B cells, the actin cytoskeleton is extensively coupled to B cell receptor (BCR) signalling pathways, and defects of the actin cytoskeleton can either promote or (Source: Nature Reviews Immunology)

From T cells to macrophages, mitochondria form the nexus of the various metabolic pathways that define each immune cell subset. In this central position, mitochondria help to control the various metabolic decision points that determine (Source: Nature Reviews Immunology)
