Project description:Relatively little is understood about the dynamics of global host–pathogen transcriptome changes that occur during bacterial infection of mucosal surfaces. To test the hypothesis that group A Streptococcus (GAS) infection of the oropharynx provokes a host transcriptome response, we performed genome-wide transcriptome analysis using a nonhuman primate model of experimental pharyngitis. We also identified host and pathogen biological processes and individual host and pathogen gene pairs with correlated patterns of expression, suggesting interaction. For this study, 509 host genes and seven biological pathways were differentially expressed throughout the entire 32-day infection cycle. GAS infection produced an initial widespread significant decrease in expression of many host genes, including those involved in cytokine production, vesicle formation, metabolism, and signal transduction. This repression lasted until day 4, at which time a large increase in expression of host genes was observed, including those involved in protein translation, antigen presentation, and GTP-mediated signaling. The interactome analysis identified 73 host and pathogen gene pairs with correlated expression levels. We discovered significant correlations between transcripts of GAS genes involved in hyaluronic capsule production and host endocytic vesicle formation, GAS GTPases and host fibrinolytic genes, and GAS response to interaction with neutrophils. We also identified a strong signal, suggesting interaction between host γδ T cells and genes in the GAS mevalonic acid synthesis pathway responsible for production of isopentenyl-pyrophosphate, a short-chain phospholipid that stimulates these T cells. Taken together, our Q:2 results are unique in providing a comprehensive understanding of the host–pathogen interactome during mucosal infection by a bacterial pathogen.

Project description:The biotrophic fungal pathogen Ustilago maydis cause common smut in maize, and lead to gall formation on all aerial organs, especially on maize kernel thus reduce yield. The interaction of U. maydis with maize is a well-established model to study the interaction between maize and biotrophic pathogen. U. maydis infection could activate host immune responses including: ROS accumulation, protease activation, salicylic acid signaling. U. maydis employ several strategies to overcome maize immune response, thus initial the biotrophic interaction with host. It has been suggested that genetic factors of maize host affected the disease severity of U. maydis infection, here we investigated the transcriptome profile of resistance and susceptible maize lines upon U. maydis infection, thus propose candidate maize genes involved in the defense response in maize to corn smut cause by U. maydis.
