The global transcriptome of whole lungs extracted from M. tuberculosis infected C57BL6 mice

The study aims at understanding the global nature of the immune responses within the the lung tissue 28 days post infection with Mycobacterium tuberculosis. Comparing the whole transcriptome of infected lungs to that of an uninfected lungs revealed a plethora of immune mechanisms driven by various cytokines. IFN-?, IL-6, IL-2, TNFa were the major cytokines observed. We observed significant differential expression of gene involved in the JAK-STAT and the MAPK signalling pathways. We observed an interplay of the immune regulatory genes and various non-immune genes controlling the metabolism, apoptosis, cell growth, post translational modifications etc.
