- Abstract
- Necrotic enteritis (NE) is a re-emerging disease as a result of increased restriction on the use of antibiotics in poultry. However, the molecular mechanisms underlying the pathogenesis of NE are unclear. Small RNA transcriptome analysis was performed using spleen and intestinal intraepithelial lymphocytes (IEL) from 2 inbred chicken lines selected for resistance or susceptibility to Marek's disease (MD) in an experimentally induced model of avian NE to investigate whether microRNA (miRNA) control the expression of genes associated with host response to pathogen challenge. Unique miRNA represented only 0.02 to 0.04% of the total number of sequences obtained, of which 544 were unambiguously identified. Hierarchical clustering revealed that most of miRNA in IEL were highly expressed in the MD-susceptible line 7.2 compared with MD-resistant line 6.3. Reduced CXCL14 gene expression was correlated with differential expression of several unique miRNA in MD-resistant chickens, whereas TGF beta R2 gene expression was correlated with altered gga-miR-216 miRNA levels in MD-susceptible animals. In conclusion, miRNA profiling and deep sequencing of small RNA in experimental models of infectious diseases may be useful for further understanding of host-pathogen interactions, and for providing insights into genetic markers of disease resistance.
