The aim of this paper was to present the role of human papillomavirus (HPV) in cervical carcinogenesis from several aspects. By explaining the HPV virus lifecycle and structure, its effect on cervical cell cycle and subversion of immune response can be better understood. Early E region of the viral genome encodes proteins that are directly involved in carcinogenesis. The E6 protein binds to p53 protein (product of tumor-suppressor gene) blocking and degrading it, which in turn prevents cell cycle arrest and apoptosis induction. E6 is also capable of telomerase activation, which leads to cell immortalization; it also reacts with host proto-oncogene c-jun, responsible for transcription, shortens G1 phase and speeds up the transition from G1 to S phase of the cells infected by HPV. E7 forms bonds with retinoblastoma protein (product of tumor-suppressor gene) and inactivates it. It can inactivate cyclin inhibitors p21, p27, and abrogate the mitotic spindle checkpoint with the loss of protective effect of pRB and p53. The immune system cannot initiate early immunological reaction since the virus is non-lytic, while the concentration of viral proteins - antigens is low and has a basal intracellular position. Presentation through Langerhans cells (LC) is weak, because the number of these cells is low due to the effect of HPV. E7 HPV reduces the expression of E-cadherin, which is responsible for LC adhesion to HPVtransformed keratinocytes. Based on these considerations, it may be concluded that the process of cervical carcinogenesis includes viral, genetic, cellular, molecular-biological, endocrine, exocrine and immunological factors.
