Microarrays for Studying the Host Transcriptional Response to Microbial Infection and for the Identification of Host Drug Targets

It is essential to understand the molecular basis of a host's response to microbial infection so that disease and tissue damage can be prevented. Modulation of host RNA expression is a critical set of molecular changes that occur upon infection. Global analysis of gene expression should provide an understanding of host RNA transcriptional changes that occur upon host-pathogen interaction. This series of articles focuses on the use of microarrays for analyzing the transcriptional response of a host to microbial infection and for drug target identification.
