摘要:
A synthetic, codon-optimized Hantaan virus (HTNV) full-length M gene open reading frame that consists of a unique nucleotide sequence encoding HTNV proteins. This synthetic gene was cloned into a plasmid to form the first optimized HTNV full-length M gene that elicits neutralizing antibodies in animals when delivered in combination with a similarly optimized Puumala virus (PUUV) DNA vaccine. The invention obviates the need for an extraneous gene sequence that was previously required for expression of the non-optimized HTNV gene. The synthetic gene is engineered into a molecular vaccine system to prevent hemorrhagic fever with renal syndrome (HFRS) caused by infection with HTNV, SEOV, or DOBV. Alternatively, it can be combined with the optimized PUUV DNA vaccine to protect against HFRS caused by any hantavirus.
