Dual RNA-seq transcriptome analysis of chicken macrophage-like cells (HD11) infected in vitro with Eimeria tenella

In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chicken macrophage cell cultures of cell line HD-11 were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 2, 4, 12, 24, 48 and 72 hours post-infection and, purified and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chicken macrophages with uninfected ones at the same time points post-infection and comparing E. tenella samples during the infection with a sample of pure sporozoites. The results show a variety of response signals in the chicken, both previously known and unknown, as well as a clear role for different sets of SAG and MIC proteins for sporozoites and merozoites of E. tenella mRNA profiles of chicken macrophage cells, both uninfected and infected with Eimeria tenella sporozoites
