IL-33 induces immunosuppressive neutrophils via a type 2 innate lymphoid cell/IL-13/STAT6 axis and protects the liver against injury in LCMV infection-induced viral hepatitis.

Viral hepatitis is still a public health problem affecting several million people around the world. Neutrophils are polymorphonuclear cells that have a critical role in antibacterial infection. However, the role of neutrophils in viral infection is not fully understood.

Radiation therapy utilization and outcomes for older women with breast cancer: Impact of molecular subtype and tumor grade.

Background: Radiation therapy (RT) utilization for elderly women with respect to human epidermal growth factor receptor 2 (HER2) receptor status has not been evaluated. Our purpose was to determine differences in RT utilization and breast cancer specific survival (BCSS) for elderly breast cancer patients with distinct molecular biomarkers.

Methods: The Surveillance, Epidemiology, and End Results database was queried for women ≥70 years of age diagnosed with T1N0M0 breast cancer between 2010 and 2013 receiving breast conservation.

A tightly regulated IL-22 response maintains immune functions and homeostasis in systemic viral infection.

Interleukin-22 (IL-22) plays an important role in host immunity and tissue homeostasis in infectious and inflammatory diseases. However, the function and regulation of IL-22 in viral infection remain largely unknown. Here, we report that viral infection triggered early IL-22 production from the liver and lymphoid organs.
