 ENGLEWOOD, CO ACCESSWIRE May 12, 2021 Aytu BioPharma, Inc. NASDAQ:AYTU, a specialty pharmaceutical company focused on commercializing novel therapeutics and consumer healthcare products, announced today that in vitro data related to the ultraviolet UV A light used in the HealightTM UVA endotracheal catheter technology was published in BioRxiv, an online archive for health science manuscripts that are not yet peer reviewed. The manuscript titled Ultraviolet-A light increases mitochondrial anti-viral signaling protein via cell-cell communication concluded that UVA light increases the expression of mitochondrial antiviral-signaling MAVS protein within cells, and the results suggest that this transmission of an increase in intracellular MAVS involves cell-to-cell communication.
