Murine models of obesity suggest that decreases in the adipose tissue regulatory T cell compartment may contribute to insulin resistance, but how this corresponds in the human clinical context is less well understood. Here the authors propose a role for interferon gamma in shrinking the adipose tissue regulatory T cell compartment seen in human obesity and assess the alterations seen during induction of dietary changes.

A new GWAS of schizophrenia (11,260 cases and 24,542 controls) and meta-analysis identifies 50 new associated loci and 145 loci in total. The common variant association signal is highly enriched in mutation-intolerant genes and in regions under strong background selection.

Myeloid cells are implicated in the innate immune and inflammatory response during infection with Chlamydia trachomatis. Here the authors show the evasion of the neutrophil response to infection and concomitant induction of sterile immunity via the purinergic P2X7 receptor.
