Abstract:To develop a novel and practicable immunomodulator, the recombinant Pichiapastoris to co-express porcine interleukin-2 and fusion antimicrobial peptide gene were constructed by 2A self-cleavage technique, and then fermented to feed ICR mice by gavage to evaluate its effects on the immunity and growth of mice via real time fluorescent quantitative PCR, ELISA and flow-cytometry. It was found that the expressed molecules of recombinant yeasts not only showed remarkable immunological bioactivity but also manifested obvious antimicrobial activity in vitro. The feeding of the yeast relatively improved the growth of mice in comparison to the control group (P<0.05). The contents of IgG, IgG1 and IgG2a were significantly increased in the yeast-treated groups (P<0.05), and the expression levels of the TLR1, TLR4, TLR6, TLR9, IL-7, IL-15, IL-23, CD62L, IL-2, IL-4, IL-6, IL-12, CRP4 and CAMP genes significantly increased in comparison to the control (P<0.05). Similarly, significant increases of the leukocytes, Th and Tc cells were detected in the blood of yeast-treated mice (P<0.05). Meanwhile, the mice of yeast-treated groups displayed markedly higher levels of immunity and survival rates than those of the control after challenged with virulent bacteria Escherichia coli and Staphylococcus aureus (P<0.05). These results suggest that the recombinant yeast can effectively enhance the immunity and growth of mice, and thus can be further developed as a promising safe and effective immunomodulator for livestock.
