At CD Genomics we've been providing dual RNA sequencing services for over 10 years to support researchers, institutes, and biotechnology and pharmaceutical companies all over the world with diverse needs. Offering a total transcriptomic solution based on our extensive experiences and know-how accumulated over the years, CD Genomics leads the field of RNA sequencing utilizing NGS, Oxford nanopore, and Pacific Biosciences technologies.
Eukaryotic host cells are subject to infection by various agents, from viruses to bacteria to parasites like fungi and protozoa. Host-pathogen interaction initiates gene expression changes within both interacting organisms, leading to the adaptation and persistence, or clearance of the pathogen. The determination of the associated gene expression changes in both the host cell and the pathogen provides insights into a comprehensive understanding of host-pathogen interactions, including identification of novel virulence factors in the pathogens and novel pathway in responses to pathogen exposure in the host. Dual RNA sequencing (RNA-seq) is emerging as a powerful tool for the dissection of the in vivo host-pathogen interplay, uncovering the influences that both organisms exert over each other. Dual RNA-seq is an ideal tool for elucidating the molecular dynamics underlying bacterial fitness and host cell phenotype among multiple divergent host cell lineages. It allows to simultaneously detect host- and pathogen-specific transcripts in mixed samples and detect low-abundance transcripts. This newfound feasibility has enabled the direct association of pathogenic gene activity with a specific host response, as well as the identification of pathogenic phenotypes that are invisible in standard virulence assays. This global, sensitive, and unbiased method has been successfully applied on several plant-pathogen models, exhibiting suitability and superiority compared with traditionally used techniques.
