Analysis of CD4(+) T-cell responses to human papillomavirus (HPV) type 11 L1 in healthy adults reveals a high degree of responsiveness and cross-reactivity with other HPV types.

ABSTRACT: Human papillomavirus type 11 (HPV-11) infection causes genital warts and recurrent respiratory papillomatosis. While there is compelling evidence that CD4(+) T cells play an important role in immune surveillance of HPV-associated diseases, little is known about human CD4(+) T-cell recognition of HPV-11. We have investigated the CD4(+) T-cell responses of 25 unrelated healthy donors to HPV-11 L1 virus-like particles (VLP). CD4(+) T-cell lines from 21 of 25 donors were established. Cell sorting experiments carried out on cells from six donors demonstrated that the response was located in the CD45RA(low) CD45RO(high) memory T-cell population. To determine the peptide specificity of these responses, epitope selection was analyzed by using 95 15-mer peptides spanning the entire HPV-11 L1 protei
