Neutralizing antibody

From WikiMD's Wellnesspedia

(Redirected from Neutralisation (immunology))

Neutralizing antibody is a type of antibody that defends a cell from a pathogen or infectious particle by neutralizing any effect it has biologically. Neutralizing antibodies are part of the humoral immune response, which is mediated by B cells.

Function[edit | edit source]

Neutralizing antibodies function by binding to a pathogen and blocking its ability to infect host cells. They do this by attaching to the pathogen in a way that blocks its sites used for entering the host cell. This prevents the pathogen from interacting with host cells and initiating an infection.

Role in Immunity[edit | edit source]

Neutralizing antibodies play a crucial role in the immune response to infections. They are produced by the immune system in response to an infection or vaccination. Once produced, they can provide immunity against future infections by the same pathogen. This is the basis for vaccine-induced immunity.

Role in Disease[edit | edit source]

In some diseases, such as HIV and Influenza, the virus can mutate and change its surface proteins, which can make it difficult for neutralizing antibodies to recognize and bind to the virus. This is one reason why these diseases can be difficult to control and why new vaccines need to be developed regularly.

Role in COVID-19[edit | edit source]

Neutralizing antibodies have been a focus of research in the COVID-19 pandemic. They are thought to play a key role in immunity to the SARS-CoV-2 virus. Studies have shown that people who recover from COVID-19 develop neutralizing antibodies, and these antibodies can be detected in the blood for several months after recovery.
