The proteolytic cleavage sites were all hexylbasic amino acids RRRKKR, with exception of LH (GKRKKR), which were the characteristic sequence of the highly pathogenic strains;

对其氨基酸序列进行分析，蛋白酶裂解位点序列除LH株为GKRKKR外，其余三株为RRRKKR，为高致病性禽流感病毒的特征序列；

Did the authors use some protease inhibitor to avoid the degradation of the protein content in the view of the increased proteolytic activity in GCF from diseased sites?

因为炎症位点的GCF中蛋白水解活性会增加，作者是否使用蛋白酶抑制剂以避免蛋白含量的降解？
