RNA-seq for Host-Pathogen Interactions: Evaluating Dual RNA-seq for Simultaneous Transcriptomic Analysis
Overview
This paper evaluates the feasibility and advantages of dual RNA-seq methodology for analyzing gene expression changes in both host and pathogen organisms simultaneously. The review argues that RNA-seq represents a significant advancement over traditional reverse transcription PCR methods, enabling a discovery-based approach to understanding host-pathogen interactions without requiring physical separation of cells.

RNA-seq for Host-Pathogen Interactions
In order to understand the interactions between host and pathogens, there is a need to understand the related gene expressions changes in both. The traditional, approaches such as the reverse transcription PCR usually need the host and pathogen cells to be separated physically before the gene expression analysis is carried out. However, in developing the probe-independent RNA-sequencing (RNA-seq) method emerged as a way of revolutionizing the transcriptomics. The purpose of the paper is the evaluation and assessment of the feasibility of improving transcriptomics one step further through the performance of a dual RNA-seq, where the expression of genes changes in both the host and pathogen are evaluated at the same time (Westermann, Gorski, and Vogel 618).
The outcome affirms that RNA-seq offers opportunities for unparalleled access to the transcriptomes of the pathogens and hosts. This enhances the annotation of the genomes, as well as the detection of the new genes. Further, RNA-seq application allowed the change from the hypothesis-based method for the study of mechanisms in infection to a discovery-based approach that is not biased, with a high potential of highlighting the novel principles (Westermann, Gorski, and Vogel 626). The paper reviewed previous studies regarding RNA-seq to evaluate the feasibility of RNA-seq in studying the interactions between hosts and pathogens.
