Production and verification of human papillomavirus type 18 vaccine in vitro.
This study aimed to generate human papillomavirus (HPV) type 18 L1 virus-like particles (VLPs) and investigated the immunity effectiveness in vitro by using the Bac to Bac baculovirus expression system and Ni-NTA purification system to express and purify the VLP. The bio-function and immune response of purified VLP were analyzed by a mouse erythrocyte haemagglutination assay and the IFN-gamma E...
متن کاملConstruction and evaluation of human papillomavirus genotype 18 pseudovirions
Introduction: Cervical cancer is the second most common cancer in women worldwide and the role of human papillomavirus (HPV) has been proved in its etiology. The currentley available L1-capsid-protein-based vaccine is highly immunogenic and very high titers of serum antibodies can be obtained by its injection, but unfortunately it is restricted to only a few HPV genotypes and is relatively expe...
متن کاملPresence of Human Papillomavirus -16 and -18 Among Women with Breast Cancer in Isfahan Province
Background: Various studies proposed virus infection is to be a possible cause of human breast cancer. However, the data argue the association between virus and cancer are inconsistent. This study was conducted to detect whether HPV-DNA is present in tissue samples of breast cancer in Isfahan province. Materials and Methods: Paraffin embedded formalin fixed specimens were prepared from 40 brea...
متن کاملA phase I study to evaluate a human papillomavirus (HPV) type 18 L1 VLP vaccine.
Human papillomavirus (HPV) infection can cause genital warts and cervical cancer. HPV types 6 and 11 cause >90% of genital wart cases; HPV16 and 18 cause 70% of cervical cancers. A prophylactic HPV (types 6, 11, 16, 18) L1 virus-like particle (VLP) vaccine may substantially reduce the incidence of these lesions. This report describes the results of a phase I study of the HPV18 component of such...
متن کاملHuman Papillomavirus Type16- L1 VLP Production in Insect Cells
Objective(s): Infection by high-risk papillomavirus is regarded as the major risk factor in the development of cervical cancer. Recombinant DNA technology allows expression of the L1 major capsid protein of HPV in different expression systems, which has intrinsic capacity to self-assemble into viral-like particles (VLP). VLPS are non-infectious, highly immunogenic and can elicit neutralizing...
