干扰素的生产已知人干扰素(HuIFN)有三型:HuIFN-α、HuIFN-β和 HuIFN-γ。HuIFN-α约有14个亚型,每一亚型系一特定基因的产物,它们的氨基酸序列的差别可高达30%,在体外亦观察到一些生物学上的差别,这些差别的临床意义尚不清楚。HuIFN-β似只有一种,有若干氨基酸序 Production of interferons Human interferons (HuIFN) are known to have three types: HuIFN-α, HuIFN-β and HuIFN-γ. There are about 14 subtypes of HuIFN-α. Each subtype is the product of a specific gene. Their amino acid sequence can be up to 30% different. Some biological differences are observed in vitro. The clinical significance of these differences is still high. Not sure. There is only one type of HuIFN-β with several amino acid sequences
