Avian influenza is a disease with every possibility to evolve as a human-to-human pandemic arising out of frequent mutations and genetic reassortment or recombination of avian influenza (AI) virus. The greatest concern is that till date, no satisfactory medicine or vaccines are available, leading to massive culling of poultry birds, causing huge economic loss and ban on export of chicken products, which emphasizes the need to develop an alternative strategy for control of AI. In the current study, we attempt to explore the molecular mechanism of innate immune potential of ducks against avian influenza. In the present study, we have characterized immune response molecules such as duck TLR3, TLR7, and RIGI that are predicted to have potent antiviral activities against the identified strain of avian influenza through studies (molecular docking) followed by experimental validation with differential mRNA expression analysis. Future exploitation may include immunomodulation with the recombinant protein, and transgenic or gene-edited chicken resistant to bird flu.
禽流感是一种极有可能因禽流感(AI)病毒频繁突变以及基因重配或重组而演变成人际大流行的疾病。最令人担忧的是,迄今为止尚无令人满意的药物或疫苗,这导致大量家禽被扑杀,造成巨大经济损失,并致使鸡肉产品出口被禁,这凸显了制定控制禽流感替代策略的必要性。在当前研究中,我们试图探究鸭子抗禽流感先天免疫潜能的分子机制。在本研究中,我们已对免疫反应分子进行了表征,如鸭TLR3、TLR7和RIGI,通过研究(分子对接)预测这些分子对已鉴定的禽流感毒株具有强大的抗病毒活性,随后通过差异mRNA表达分析进行实验验证。未来的应用可能包括用重组蛋白进行免疫调节,以及培育抗禽流感的转基因或基因编辑鸡。
