Middle East respiratory syndrome coronavirus (MERS-CoV) is not efficiently transmitted between humans, but it is highly prevalent in dromedary camels. Here we report that the MERS-CoV receptor--dipeptidyl peptidase 4 (DPP4)--is expressed in the upper respiratory tract epithelium of camels but not in that of humans. Lack of DPP4 expression may be the primary cause of limited MERS-CoV replication in the human upper respiratory tract and hence restrict transmission.
中东呼吸综合征冠状病毒(MERS-CoV)在人与人之间传播效率不高,但在单峰骆驼中高度流行。我们在此报告,MERS-CoV受体——二肽基肽酶4(DPP4)——在骆驼的上呼吸道上皮中表达,而在人类上呼吸道上皮中不表达。缺乏DPP4表达可能是MERS-CoV在人类上呼吸道中复制受限并因此限制传播的主要原因。
