| Sumario: | In vitro differentiation of donor blood monocytes to macrophages (Mph) following GM-CSF treatment was accompanied by a significant increase in the levels of gene transcription signaling receptors TLR7 or RIG1. The levels of intracellular viral RNA (M1 gene) in Mph remained high upon infection by influenza virus A H1N1pdm (Moscow 2009) for 24-96 hours. The innate immunity reactions caused by influenza virus show individual features: they are decreased in Mph from donor 1 which had initially high level of endosomal TLR7 gene activity, and it increased by influenza virus in MPh from donor 2 who had a very low level of TLR7 gene expression. The influenza H1N1pdm virus weakly stimulated expression of gene RIG1 and production of inflammatory cytokines in Mf in donor 1. The differences may be connected with individual sensitivity of the donors to influenza infection. |
