  2. Oncolytic virus - Wikipedia

    en.wikipedia.org/wiki/Oncolytic_virus

    Cancer cells and virus-infected cells have similar alterations in their cell signalling pathways, particularly those that govern progression through the cell cycle. [84] A viral gene whose function is to alter a pathway is dispensable in cells where the pathway is defective, but not in cells where the pathway is active. [citation needed]

    The Papanicolaou smear ("Pap" smear) is a widely used cancer screening test for cervical cancer. DNA-based tests to identify the virus are also available. [12] Herpesviruses are a third group of common cancer-causing viruses. Two types of herpesviruses have been associated with cancer: the Epstein–Barr virus (EBV) and human herpesvirus 8 (HHV ...

    en.wikipedia.org/wiki/Oncovirus

    A 2020 study of 2,658 samples from 38 different types of cancer found that 16% were associated with a virus. [8] These cancers might be easily prevented through vaccination (e.g., papillomavirus vaccines), diagnosed with simple blood tests, and treated with less-toxic antiviral compounds.

    The dendritic cells process the dead cancer cells and present components of them to other cells of the immune system. [219] Having completed successful clinical trials, the virus gained approval for the treatment of melanoma in late 2015. [220] Viruses that have been reprogrammed to kill cancer cells are called oncolytic viruses. [221]

  6. Merkel cell polyomavirus - Wikipedia

    en.wikipedia.org/wiki/Merkel_cell_polyomavirus

    Sequencing of the virus from Merkel cell cancers reveals that it generally has tumor-specific mutations that truncate the MCV T antigen. These mutations (which are not found in native virus obtained from nontumor sites) eliminate the T antigen helicase, preventing the integrated virus from replicating independently from the host cancer cell. [10]

    Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
