Low Dose Hyperoxia Primes Airways for Fibrosis in Mice after Influenza A Infection.

Am J Physiol Lung Cell Mol Physiol 2021 Jul 29. Epub 2021 Jul 29.

Department of Pediatrics, grid.16416.34University of Rochester, Rochester, NY, United States.

It is well known that supplemental oxygen used to treat preterm infants in respiratory distress is associated with permanently disrupting lung development and the host response to influenza A virus (IAV). However, many infants who go home with normally functioning lungs are also at risk for hyperreactivity after a respiratory viral infection. We recently reported a new, low-dose hyperoxia mouse model (40% for 8 days; 40x8) that causes a transient change in lung function that resolves, rendering 40x8 adult animals functionally indistinguishable from room air controls.

Losing the dogmatic view of cerebral autoregulation.

Physiol Rep 2021 Aug;9(15):e14982

Center for Heart, Lung and Vascular Health, School of Health and Exercise Sciences, University of British Columbia - Okanagan, Kelowna, BC, Canada.

In 1959, Niels Lassen illustrated the cerebral autoregulation curve in the classic review article entitled Cerebral Blood Flow and Oxygen Consumption in Man. This concept suggested a relatively broad mean arterial pressure range (~60-150 mmHg) wherein cerebral blood flow remains constant. However, the assumption that this wide cerebral autoregulation plateau could be applied on a within-individual basis is incorrect and greatly variable between individuals. Read More

ADP-ribosyltransferases, an update on function and nomenclature.

FEBS J 2021 Jul 29. Epub 2021 Jul 29.

Institute of Basic Medical Sciences, University of Oslo, Sognsvannsveien 9, 0372, Oslo, Norway.

ADP-ribosylation, a modification of proteins, nucleic acids and metabolites, confers broad functions, including roles in stress responses elicited for example by DNA damage and viral infection and is involved in intra- and extracellular signaling, chromatin and transcriptional regulation, protein biosynthesis and cell death. ADP-ribosylation is catalyzed by ADP-ribosyltransferases, which transfer ADP-ribose from NAD onto substrates. The modification, which occurs as mono- or poly-ADP-ribosylation, is reversible due to the action of different ADP-ribosylhydrolases. Read More
