Papillomaviridae: HPV

O vírus do papiloma humano ( HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV), pela sigla em inglês) é um vírus de DNA DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

Os seres humanos são o único reservatório e a transmissão ocorre através do contacto com a pele ou sexual. Os vírus do papiloma humano infetam células epiteliais basais e podem afetar proteínas reguladoras de células, resultando na proliferação celular.

Classificação

Fluxograma de classificação de vírus de DNA

Identificação de vírus de DNA:
Os vírus podem ser classificados de várias formas. Contudo, a maioria dos vírus possui um genoma formado por DNA ou RNA. Os vírus com genoma de DNA podem ainda ser caracterizados como de cadeia simples ou dupla. Os vírus com envelope são revestidos por uma camada fina de membrana celular, que geralmente é retirada da célula hospedeira. Os vírus sem envelope são apelidados de vírus “nus”. Alguns vírus com envelope traduzem DNA em RNA antes de serem incorporados no genoma da célula hospedeira.
