New role for DCR-1/dicer in Caenorhabditis elegans innate immunity against the highly virulent bacterium Bacillus thuringiensis DB27.

Infection and immunity 20130805 10

Bacillus thuringiensis produces toxins that target invertebrates, including Caenorhabditis elegans. Virulence of Bacillus strains is often highly specific, such that B. thuringiensis strain DB27 is highly pathogenic to C. elegans but shows no virulence for another model nematode, Pristionchus pacificus. To uncover the underlying mechanisms of the differential responses of the two nematodes to B. thuringiensis DB27 and to reveal the C. elegans defense mechanisms against this pathogen, we conducte ...[more]

C. elegans young adults: Exposed to Bacillus thuringiensis DB27 versus exposed to E. coli OP50 : 4 hours

Project description:Transcriptional profiling of C. elegans young adult worms exposed to pathogen Bacillus thuringiensis DB27 for 4 hours versus age-matched worms exposed to onctrol lab food E. coli OP50. The goal was to identify genes regulated in response to pathogen. The broader goal of study was to study evolution of pathogen response by comparing this expression profile to that obtained by exposing the nematode Pristionchus pacificus to the same pathogen. Other experiments which are a part of this study include expression profiling of C. elegans and P. pacificus on other pathogens including Staphylococcus aureus, Serratia marcescens, Xenorhabdus nematophila. Keywords: Expression profiling by array One-condition experiments. C. elegans young adults: Exposed to Bacillus thuringiensis DB27 versus exposed to E. coli OP50 : 4 hours. 3 biological replicates for each condition, including 1 dye-swap.
