Temporal and Tissue Specific Changes in Expression of Nutrient Transporters and Host Defense Peptides in Young Broilers during Salmonella and Campylobacter infections
… in mRNA abundance of nutrient transporters and avian beta-defensins (AvBD) vary by day, tissue and challenge dose. ZnT1 may play an important role during a Salmonella challenge as mRNA abundance of ZnT1 significantly increased (P<0.05) by day 7 in the 108 group compared to the control. Early …

Developmental gene expression of host defense peptides in immune organs and the small intestine of turkey poults (Meleagris gallopavo)
… not fully developed. There are three classes of avian HDPs: avian beta defensins (AvBDs), cathelicidins (Cath) and liver-expressed antimicrobial peptide 2 (LEAP-2). The objective was to compare expression of HDPs in male turkey poults at day of hatch (D0), D7, D14, D21 and D28 from the thymus, …

Evolutionary forces shaping innate immune gene variation in a bottlenecked population of the Seychelles warbler
… selection within this system by using avian beta-defensins and toll-like receptor genes to examine functional variation. First, I characterise variation within both gene groups in this population and show that this species’ demographic history has had an overriding effect on selection …

Cellular Events During Coccidial Infection in Chickens
Avian coccidiosis is caused by the intestinal protozoa Eimeria. The parasite's site of infection in the intestine is site specific. Eimeria acervulina mainly affects the duodenum, E. maxima the jejunum, and E. tenella the ceca. Lesions in the intestinal mucosa cause reduced feed efficiency and body …

Ontogeny and biological function of epithelial cells in the chicken yolk sac and small intestine
… intestinal epithelia and the yolk sac secrete beta defensins for promoting intestinal health. Since there are heterogeneous cell types along the mammalian intestinal villus, which are derived from the intestinal stem cells in the crypts, we investigated if cells of the chicken yolk sac and …
