The cIAP ubiquitin ligases sustain type 3 γδ T cells and ILC during aging to promote barrier immunity.

Early-life cues shape the immune system during adulthood. However, early-life signaling pathways and their temporal functions are not well understood. Herein, we demonstrate that the cellular inhibitor of apoptosis proteins 1 and 2 (cIAP1/2), which are E3 ubiquitin ligases, sustain interleukin (IL)-17-producing γ δ T cells (γδT17) and group 3 innate lymphoid cells (ILC3) during late neonatal and prepubescent life.

Oxidative Stress and Indicators of Brain Damage Following Pediatric Heart Surgery.

Pediatric cardiac surgery induces an increased oxidative stress (OS) response. Increased OS is associated with poor neurologic outcomes in neonatal populations with similar patterns of brain injury. We investigated OS and brain injury in infants undergoing heart surgery.

Ozone therapy for patients with COVID-19 pneumonia: Preliminary report of a prospective case-control study.

Background: There is still no specific treatment strategies for COVID-19 other than supportive management.

Design: A prospective case-control study determined by admittance to the hospital based on bed availability.

Participants: Eighteen patients with COVID-19 infection (laboratory confirmed) severe pneumonia admitted to hospital between 20th March and 19th April 2020.

Potential Role of Oxygen-Ozone Therapy in Treatment of COVID-19 Pneumonia.

BACKGROUND Pneumonia caused by coronavirus originated in Wuhan, China in late 2019 and has spread around the world, becoming a pandemic. Many patients deteriorate rapidly and require intubation and mechanical ventilation, which is causing the collapse of healthcare systems in many countries. Coronavirus infection is associated with extensive lung inflammation and microvascular thrombosis, which can result in hypoxia.

The neonatal microenvironment programs innate γδ T cells through the transcription factor STAT5.

IL-17-producing RORγt+ γδ T cells (γδT17 cells) are innate lymphocytes that participate in type 3 immune responses during infection and inflammation. Herein, we show that γδT17 cells rapidly proliferate within neonatal lymph nodes and gut, where, upon entry, they upregulate T-bet and coexpress IL-17, IL-22, and IFN-γ in a STAT3- and retinoic acid-dependent manner. Neonatal expansion was halted in mice conditionally deficient in STAT5, and its loss resulted in γδT17 cell depletion from all adult organs.
