Human papillomavirus infection is caused by a DNA virus from the Papillomaviridae family. Many HPV infections cause no symptoms and 90% resolve spontaneously within two years. In some cases, an HPV infection persists and results in either warts or precancerous lesions. These lesions, depending on the site affected, increase the risk of cancer of the cervix, vulva, vagina, penis, anus, mouth, tonsils, or throat. Nearly all cervical cancer is due to HPV, and two strains – HPV16 and HPV18 – account for 70% of all cases. HPV16 is responsible for almost 90% of HPV-positive oropharyngeal cancers. Between 60% and 90% of the other cancers listed above are also linked to HPV. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis.
Papillomaviridae is a family of non-enveloped DNA viruses whose members are known as papillomaviruses. Several hundred species of papillomaviruses, traditionally referred to as "types", have been identified infecting all carefully inspected mammals, but also other vertebrates such as birds, snakes, turtles and fish. Infection by most papillomavirus types, depending on the type, is either asymptomatic or causes small benign tumors, known as papillomas or warts. Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous.
The measles virus (MV), with scientific name Morbillivirus hominis, is a single-stranded, negative-sense, enveloped, non-segmented RNA virus of the genus Morbillivirus within the family Paramyxoviridae. It is the cause of measles. Humans are the natural hosts of the virus; no animal reservoirs are known to exist.
A Langerhans cell (LC) is a tissue-resident macrophage of the skin once thought to be a resident dendritic cell. These cells contain organelles called Birbeck granules. They are present in all layers of the epidermis and are most prominent in the stratum spinosum. They also occur in the papillary dermis, particularly around blood vessels, as well as in the mucosa of the mouth, foreskin, and vaginal epithelium. They can be found in other tissues, such as lymph nodes, particularly in association with the condition Langerhans cell histiocytosis (LCH).
Margaret Anne Stanley, OBE FMedSc, is a British virologist and epithelial biologist. She attended the Universities of London, Bristol, and Adelaide. As of 2018, she is an Emeritus Professor of Epithelial Biology in the Department of Pathology at the University of Cambridge and a Fellow of the Academy of Medical Sciences. She is also an Honorary Fellow of the UK Royal College of Obstetricians and Gynaecologists and an honorary fellow of Christ's College, Cambridge. Stanley is a research scientist in virology focusing on the human papillomavirus (HPV). Her research work has led to new scientific findings on HPV. Additionally, she uses her expertise on HPV to serve on multiple advisory committees and journal editorial boards.
The Coronavirus packaging signal is a conserved cis-regulatory element found in Betacoronavirus. It has an important role in regulating the packaging of the viral genome into the capsid. As part of the viral life cycle, within the infected cell, the viral genome becomes associated with viral proteins and assembles into new infective progeny viruses. This process is called packaging and is vital for viral replication.
Vincent R. Racaniello is a Higgins Professor in the Department of Microbiology and Immunology at Columbia University's College of Physicians and Surgeons. He is a co-author of a textbook on virology, Principles of Virology.
2F5 is a broadly neutralizing human monoclonal antibody (mAb) that has been shown to bind to and neutralize HIV-1 in vitro, making it a potential candidate for use in vaccine synthesis. 2F5 recognizes an epitope in the membrane-proximal external region (MPER) of HIV-1 gp41. 2F5 then binds to this epitope and its constant region interacts with the viral lipid membrane, which neutralizes the virus.
David Mahan Knipe is the Higgins Professor of Microbiology and Molecular Genetics in the Department of Microbiology at the Harvard Medical School in Boston, Massachusetts and co-chief editor of the reference book Fields Virology. He returned to the Chair of the Program in Virology at Harvard Medical School in 2019, having previously held the position from 2004 through 2016 and served as interim Co-Chair of the Microbiology and Immunobiology Department from 2016 through 2018.
Anna-Lise WilliamsonMASSAf is a Professor of Virology at the University of Cape Town. Williamson obtained her PhD from the University of the Witwatersrand in 1985. Her area of expertise is human papillomavirus, but is also known on an international level for her work in developing vaccines for HIV. These vaccines have been introduce in phase 1 of clinical trial. Williamson has published more than 120 papers.
Julius S. Youngner was an American Distinguished Service Professor in the School of Medicine and Department of Microbiology & Molecular Genetics at University of Pittsburgh responsible for advances necessary for development of a vaccine for poliomyelitis and the first intranasal equine influenza vaccine.
Susan Zolla-Pazner is an American research scientist who is a Professor of Medicine in the Division of Infectious Diseases and the Department of Microbiology at Mount Sinai School of Medicine and a guest investigator in the Laboratory of Molecular Immunology at The Rockefeller University, both in New York City. Zolla-Pazner's work has focused on how the immune system responds to the human immunodeficiency virus (HIV) and, in particular, how antibodies against the viral envelope develop in the course of infection.
Eric Murnane Poeschla is an American infectious disease physician, virologist, and innate immunologist.
Patricia Gail Spear is an American virologist. She is a professor emeritus of microbiology and immunology at Northwestern University in Evanston, Illinois.
