Kratchmarov et al. identified a GATA3⁺ T_H2 population that expresses the transcription factors TCF1 and LEF1 and sustains type 2 inflammation in tissues over a human lifetime, despite chronic antigen exposure.

Here the authors identify the transcription factor MEF2C as essential for human NK cell function and viral immunity in mice and humans. This control is exerted via regulation of lipid metabolism, and deficiency in MEF2C can be overcome by oleic acid supplementation.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Cupedo and colleagues show that neutrophils promote a tumor-supportive microenvironment via a self-amplifying interaction between neutrophils and bone marrow stromal cells. This scenario creates a promyeloma niche that is difficult to treat despite targeted therapies directed at the myeloma cells.

In this Resource, the authors integrate multiomics data to show the effect of the transcription factors Blimp-1 and c-Maf on IL-10 and type 1 and 17 responses, which together protect against pathobiont-induced colitis.

Here, the authors describe biallelic loss-of-function variants in human SHARPIN in individuals with autoinflammation and immunodeficiency, termed sharpenia. They also successfully treat one of these individuals with TNF inhibitors.
