Abstract

Background: IL-2 is a cytokine that plays an active role in the activation and maintenance of both acquired and innate immune defenses. It is also capable of improving the protective immune responses that are generated by conventional vaccines against avian pathogens in the poultry industry when used as an adjuvant.
Objectives: The aim of this study was to extract and sequence Iranian chicken IL-2.
Materials and Methods: In this study, genomic DNA was extracted from Iranian chickens. Total RNA was isolated by culturing harvested splenocytesand lysing them with Trizol reagent per the manufacturer's instructions. mRNA was isolated and converted to cDNA using reverse-transcriptase (RT) and specific designed primers. Then, the PCR product was ligated into the PTZ57R/T plasmid (TA-cloning) and transformed into competent Top10 E. coli cells.
Results: A unique 668-bp band was obtained after RT-PCR. Restriction enzyme digestion and colony PCR analysis and direct sequencing confirmed the existence of the desired gene in transformants.
Conclusions: For first time in Iran, the chIL-2 gene was successfully extracted, cloned, and transferred into E. coli. The efficacy of recombinant or DNA vaccines can be modulated by codelivery of this cytokine gene.

Implication for health policy/practice/research/medical education:
The ability of chIL-2 to enhance T-cell activation and proliferation suggests that it augments the immune response when used as an adjuvant.
