RESUMO
We have previously reported that the most common human serum immunoglobulin G antibody reactivities to human papillomavirus type 16 and type 18 (HPV16 and HPV18)-encoded proteins are directed against the minor capsid proteins (HPV16 L2 and HPV18 L2) and to the E7 protein of HPV16 (S. A. Jenison, X.-P. Yu, J. M. Valentine, L. A. Koutsky, A. E. Christiansen, A. M. Beckmann, and D. A. Galloway, J. Infect. Dis. 162:60-69, 1990). In this study, the antibody-reactive segments of the HPV16 E7, HPV16 L2, and HPV18 L2 polypeptides were mapped by using nested sets of deleted recombinant proteins. A single major immunoreactive region was identified in the HPV16 E7 polypeptide between amino acids (aa) 21 and 34 (DLYCYE-QLNDSSEE). In contrast, three distinct immunoreactive regions of the HPV16 L2 polypeptide were present in the segment between aa149 and aa204, and three distinct immunoreactive regions of the HPV18 L2 polypeptide were present in the segment between aa110 and aa211. With the exception of one serum sample, serum immunoglobulin G antibodies which reacted with HPV16 L2 polypeptides or with HPV18 L2 polypeptides were not cross-reactive.
