Article Title: Transcriptomics in lung tissue upon respiratory syncytial virus infection reveals aging as important modulator of immune activation and matrix maintenance
Figure Lengend Snippet: Distinct effects by aging and RSV on gene expression. Panel A shows each individual animal in a principal component analysis (PCA) of the microarray data of lung samples derived at day 0 (mock-inoculated, black, n = 4/group), or at day 2 (red, n = 5/group) or day 5 (green, n = 5/group) after inoculation with RSV. Aging-regulated expression appears by PC1, RSV-regulated gene expression appears along PC2. Y, young (circles); O, old (triangles); M, mock control; R, RSV-inoculated. Panel B shows a Venn-diagram depicting numbers of genes that are significantly upregulated (↑), downregulated (↓), or show no significant response (−). The three symbols indicate from left to right: response to RSV in young mice, response to RSV in old mice, response to aging, respectively.
