[Production of alpha-, beta-, and lambda-interferons by epithelial and mononuclear cells during acute respiratory
Abstract:
Role of several types of cells (human broncho-epithelial cells, BEAS-2B cell line, and mononuclear cells as model of macrophages) in production of alpha-, beta- and lambda-interferons during acute respiratory viral infection was studied. Kits for detection of these interferons by quantitative PCR assay has been developed. In human broncho-epithelial cells respiratory viruses induced statistically significant expression of alpha-interferon mRNA at 8 hours after infection, beta-interferon mRNA--at 24 hours after infection, IL-29 mRNA (lambda-interferon) - at 24 hours after infection, IL-28 mRNA (lambda-interferon) - at 8 and 24 hours after infection. In BEAS-2B cell line induction of alpha-interferon mRNA expression was observed at 8 hours after infection, beta-interferon mRNA expression - at 24 hours after infection, IL-29 mRNA (lambda-interferon) expression - at 8 and 24 hours after viral challenge. Production of beta- and lambda-interferons by ELISA at 24 hours after infection has been detected. When polymorphonuclear cells were challenged, induction of alpha-, beta-, and lambda-interferons expression was observed at 8 hours after infection. Production of alpha-, beta- and lambda-interferons has been detected by ELISA at 24 hours after infection by rhinovirus 16.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
