ABSTRACT

Chicken erythrocyte, which is the most abundant cell subset in blood vessel, also exists in cartilage zone. It has recently been shown that chicken erythrocytes constitutively express toll-like receptors (TLRs), cytokines, and avian β-defensins (AvBDs). Host defense peptides (HDPs) are important effector molecules in innate immunity. In this study, thiram has been used to induce tibial dyschondroplasia (TD) and the chickens were injected with different doses of recombinant glutathione-S-transferase A3 (rGSTA3) proteins. We explored the responses of HDPs in erythrocytes to thiram-induced TD and rGSTA3 protein by quantitative real time PCR (qRT-PCR). The results showed many HDPs expressions were suppressed by thiram-induced TD, and the expressions of HDPs were upregulated by rGSTA3 protein. These findings demonstrated that mRNA expressions of HDPs are highly related to thiram-induced TD, and rGSTA3 protein enhanced the immune response of chicken erythrocytes by up-regulating HDPs expression. Future studies may be aimed at elucidating the association between the expression of these peptides and the development of the TD.
