Respiratory papillomas, caused by human papillomaviruses, are benign tumors that recur following removal. We evaluated immune function and major histocompatibility complex (MHC) phenotype and expression in these patients. MHC-independent immune function appeared normal. The frequency of peripheral blood MHC class II phenotypes was highly enriched for DQ3 and DR11, one split of DR5. Class I MHC antigen expression on papilloma tissue was markedly reduced. Together, these phenomena may facilitate papillomavirus evasion of the cellular immune response.
由人乳头瘤病毒引起的呼吸道乳头瘤是切除后会复发的良性肿瘤。我们评估了这些患者的免疫功能以及主要组织相容性复合体（MHC）的表型和表达情况。不依赖MHC的免疫功能看起来正常。外周血MHC II类表型的频率在DQ3和DR11（DR5的一个分支）中高度富集。乳头瘤组织上I类MHC抗原的表达明显降低。这些现象共同作用可能会促使乳头瘤病毒逃避免疫细胞反应。
