    Keywords : antagonism; antibody; capsids; cervical carcinoma; CIN; epidemiology; HPV; isotype; neutralizing epitope; PCR; STDs; trends over time; VLPs;

    Abstract : Background: Human Papillomavirus (HPV) is a sexually transmitted DNA virus that causes several human cancers, notably cervical and other anogenital cancers. The antibody response to this virus is of interest both because knowledge of the antigenic structures that induce protective immunity forms the basis for prophylactic vaccine development and because it forms the basis of seroepidemiology, the method of choice for studies of HPV infectivity, of HPV spread in populations and of cancer risks following HPV exposure.

    Abstract : Background: The etiologic factors behind development of lgE-mediated allergy are incompletely understood although the interaction between allergic heredity and exposure to various environmental factors seems to be most important. Objective: The overall aim of this thesis was to study the associations between allergic heredity, environmental factors like viral infections and lgE sensitisation and the development of allergic diseases during childhood.
