Interaction between proteins of the PPARγ and NFκB immune response pathways and rotavirus non-structural proteins
Abstract:
Cells infected with MA104 rotavirus and/or transfected with plasmids expressing NSP proteins, were analyzed for expression of cellular proteins related to NFκB and PPARγ pathways and evaluated through the ELISA, luminescence, flow cytometry and Western blot techniques. The association between cellular and viral (NSPs) proteins was examined by ELISA, epifluorescence and confocal microscopy techniques. It was observed that NSP1 protein interacts with RXR, NSP1, and NSP3 with PPARγ, NSP2 with p-IKKα/β and NSP5 with NFκB proteins. We have found that phosphorylated PPARγ is localized in cytoplasm and transcriptional activity of PPRE is diminished. These results lead to the conclusion, that RRV activates the proinflammatory pathway, increasing the expression of NFκB and possibly by PPARγ phosphorylation, its translocation to the nucleus is impeded, thus inactivating the proinflammatory pathway. Keywords: rotavirus; PPARγ; NFκB; NSPs; RRV.

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...
