Abstract
A recombinant alphal-antitrysin (AAT) protein or a fragment thereof expressed in a genetically modified yeast for use in the treatment of a viral infection and/or lung inflammation. In one embodiment, the viral infection is a viral respiratory infection, preferably a coronavirus infection, such as a SARS CoV infection, more preferably SARS-CoV-2. Also disclosed is a method of producing recombinant AAT protein or fragment(s) thereof from genetically modified yeast. In embodiments, the method includes the steps of culturing a genetically modified yeast comprising an exogenous nucleic acid molecule with an AAT-encoding region operably linked to a promoter or promoter/enhancer combination, expressing recombinant AAT in the cultured yeast, and isolating recombinant AAT from the culture. In embodiments, the recombinant AAT produced from yeast is prepared in a pharmaceutical composition, such as a solution, preferably suitable for nebulization and subsequent inhalation by a subject.
