Over 600 000 cancers each year are attributed to the human papillomavirus (HPV), including cervical, anogenital and oropharyngeal cancers (OPC). A key challenge in understanding HPV immunobiology is the diversity of oncogenic HPV types and the need for multiplexed display of HPV antigens to measure antibody responses. We have generated custom HPV protein microarrays displaying 98 proteins as C-terminal GST fusion proteins, representing eight antigens of two low-risk HPV types (HPV6 and 11) and ten oncogenic high-risk HPV types (HPV16, 18, 31, 33, 35, 39, 45, 51, 52 and 58). We demonstrate robust and reproducible protein expression of 96/98 of the antigens using a human cell lysate expression system. The target epitopes and specificities of four monoclonal antibodies were identified. Using sera from ten patients with newly diagnosed OPC and ten controls, we demonstrate specific IgG seroreactivity to HPV16 E1, E2, and E7 (a fold increase of 1.52, 2.19 and 1.35 in cases vs. controls, respectively, all p < 0.005), confirming our prior data on an ELISA platform. We also detect HPV52 E7 Abs in serum from a patient with cervical cancer. The HPV protein array has potential for rapid identification of serologic responses to 12 HPV types.
