An HIV vaccine is a potential vaccine that could be either a preventive vaccine or a therapeutic vaccine, which means it would either protect individuals from being infected with HIV or treat HIV-infected individuals.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. Vaccines that treat existing cancer are known as therapeutic cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient.
This is a list of AIDS-related topics, many of which were originally taken from the public domain U.S. Department of Health Glossary of HIV/AIDS-Related Terms, 4th Edition.
The Division of Acquired Immunodeficiency Syndrome (DAIDS) is a division of the National Institute of Allergy and Infectious Diseases, which is part of the National Institutes of Health. It was formed in 1986 as a part of the initiative to address the national research needs created by the advent and spread of the HIV/AIDS epidemic. Specifically, the Division's mission is to increase basic knowledge of the pathogenesis, natural history, and transmission of HIV disease and to support research that promotes progress in its detection, treatment, and prevention. DAIDS accomplishes this through planning, implementing, managing, and evaluating programs in (1) fundamental basic research, (2) discovery and development of therapies for HIV infection and its complications, and (3) discovery and development of vaccines and other prevention strategies.
Rintatolimod, sold under the tradename Ampligen, is a medication intended for treatment of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). There is some evidence it may improve some ME/CFS symptoms.
HIV superinfection is a condition in which a person with an established human immunodeficiency virus infection acquires a second strain of HIV, often of a different subtype. These can form a recombinant strain that co-exists with the strain from the initial infection, as well from reinfection with a new virus strain, and may cause more rapid disease progression or carry multiple resistances to certain HIV medications.
CD4 immunoadhesin is a recombinant fusion protein consisting of a combination of CD4 and the fragment crystallizable region, similarly known as immunoglobulin. It belongs to the antibody (Ig) gene family. CD4 is a surface receptor for human immunodeficiency virus (HIV). The CD4 immunoadhesin molecular fusion allow the protein to possess key functions from each independent subunit. The CD4 specific properties include the gp120-binding and HIV-blocking capabilities. Properties specific to immunoglobulin are the long plasma half-life and Fc receptor binding. The properties of the protein means that it has potential to be used in AIDS therapy as of 2017. Specifically, CD4 immunoadhesin plays a role in antibody-dependent cell-mediated cytotoxicity (ADCC) towards HIV-infected cells. While natural anti-gp120 antibodies exhibit a response towards uninfected CD4-expressing cells that have a soluble gp120 bound to the CD4 on the cell surface, CD4 immunoadhesin, however, will not exhibit a response. One of the most relevant of these possibilities is its ability to cross the placenta.
Neurovax is a vaccine designed to treat patients with multiple sclerosis. Developed by Immune Response BioPharma, Inc. it is currently in phase II clinical trials. Neurovax is designed to stimulate FOXP3+ regulatory T-cells that can then suppress the autoreactive T-cells in some patients.
Ibalizumab, sold under the brand name Trogarzo, is a non-immunosuppressive humanised monoclonal antibody that binds CD4, the primary receptor for HIV, and inhibits HIV from entering cells. It is a post-attachment inhibitor, blocking HIV from binding to the CCR5 and CXCR4 co-receptors after HIV binds to the CD4 receptor on the surface of a CD4 cell. Post-attachment inhibitors are a subclass of HIV drugs called entry inhibitors.
GeoVax is a clinical-stage biotechnology company which develops vaccines. GeoVax's development platform uses Modified Vaccinia Ankara (MVA) vector technology, with improvements to antigen design and manufacturing capabilities. GeoVax uses recombinant DNA or recombinant viruses to produce virus-like particles (VLPs) in the person being vaccinated.
Leronlimab is a humanized monoclonal antibody targeted against the CCR5 receptor found on T lymphocytes of the human immune system. It is being investigated as a potential therapy in the treatment of COVID-19, triple negative breast cancer, and HIV infection. The United States Food and Drug Administration has designated PRO 140 for fast-track approval. In February 2008, the drug entered Phase 2 clinical trials and a phase 3 trial was begun in 2015. In February 2018, Cytodyn Inc reported that the primary endpoint had been achieved in the PRO 140 pivotal combination therapy trial in HIV infection. In 2020 CytoDyn submitted a fast-track biologics license application for treatment of CCR5-tropic HIV-1 Infection.
MVA-B, or Modified Vaccinia Ankara B, is an HIV vaccine created to give immune resistance to infection by the human immunodeficiency virus. It was developed by a team of Spanish researchers at the Spanish National Research Council's Biotechnology National Centre headed by Dr. Mariano Esteban. The vaccine is based on the Modified vaccinia Ankara (MVA) virus used during the 1970s to help eradicate the smallpox virus. The B in the name "refers to HIV-B, the most common HIV subtype in Europe". It has been stated by Dr. Esteban that, in the future, the vaccine could potentially reduce the virulence of HIV to a "minor chronic infection akin to herpes".
SAV001-H is the first candidate preventive HIV vaccine using a killed or "dead" version of the HIV-1 virus.
HIV/AIDS research includes all medical research that attempts to prevent, treat, or cure HIV/AIDS, as well as fundamental research about the nature of HIV as an infectious agent and AIDS as the disease caused by HIV.
Fostemsavir, sold under the brand name Rukobia, is an antiretroviral medication for adults living with HIV/AIDS who have tried multiple HIV medications and whose HIV infection cannot be successfully treated with other therapies because of resistance, intolerance or safety considerations.
Viral load monitoring for HIV is the regular measurement of the viral load of individual HIV-positive people as part of their personal plan for treatment of HIV/AIDS. A count of the viral load is routine before the start of HIV treatment.
Julianna Lisziewicz is a Hungarian immunologist. Lisziewicz headed many research teams that have discovered and produced immunotheraputic drugs to treat diseases like cancer and chronic infections like HIV/AIDS. Some of these drugs have been successfully used in clinical trials.
The Immune Response Corporation (IRC) was a pharmaceutical company that worked in the development immunotherapeutic products. The firm was founded by Jonas Salk and Kevin Kimberlin when Kimberlin, "asked Salk to become lead scientific advisor for a new biotech company specializing in 'anti-idiotypes,' a novel vaccine technology." Salk called the proposal "liberating."
Passive antibody therapy, also called serum therapy, is a subtype of passive immunotherapy that administers antibodies to target and kill pathogens or cancer cells. It is designed to draw support from foreign antibodies that are donated from a person, extracted from animals, or made in the laboratory to elicit an immune response instead of relying on the innate immune system to fight disease. It has a long history from the 18th century for treating infectious diseases and is now a common cancer treatment. The mechanism of actions include: antagonistic and agonistic reaction, complement-dependent cytotoxicity (CDC), and antibody-dependent cellular cytotoxicity (ADCC).
