Distinct Tissue Damage and Microbial Cues Drive Neutrophil and Macrophage Recruitment to Thermal Injury

The authors identified distinct cues in the tissue microenvironment that differentially drive neutrophil and macrophage responses to sterile injury. Using live imaging, they found a motile zone for neutrophils, but not macrophages, in collagen-free regions and identified a specific role for interleukin-6 receptor signaling in neutrophil responses to thermal damage.

Identification of Immune Landscape Signatures Associated with Clinical and Prognostic Features of Hepatocellular Carcinoma

Investigators combined immune landscape signatures with hepatocellular carcinoma clinical and prognostic features to classify them into distinct subtypes. The immunogenomic profiles, stromal cell features and immune cell composition of the subtypes were then systematically analyzed.
