Meta-analytic approach to identify the gene expression signatures induced in host-pathogen environment upon infection by Mtb. (A) Initially the gene expression microarray datasets of human macrophages and Mtb were collected from Gene Expression Omnibus (GEO) (B). We have used R package to generate the ranked list of differentially expressed genes by comparing the samples of infected macrophages versus normal and in vitro Mtb vs. intracellular. (C) The ranked list of differentially expressed genes were combined using previously developed meta-analytic method to generate a consensus ranked list of the differentially expressed genes in macrophages as well as in Mtb.
