Immunoevasin
Immunoevasin (pronounced: im•mu•no•e•va•sin) is a term used in the field of Immunology to describe a group of proteins that are produced by certain viruses to evade the host's Immune System.
Etymology
The term "Immunoevasin" is derived from the words "Immuno", referring to the immune system, and "evasin", which means to evade or escape. Thus, the term essentially refers to the evasion of the immune system.
Function
Immunoevasins are produced by viruses, particularly Herpesviruses, to help them evade the host's immune response. They do this by interfering with the host's Antigen Presentation process, preventing the immune system from recognizing and attacking the virus. Some immunoevasins also inhibit the function of Cytokines, which are crucial for immune response.
Types of Immunoevasins
There are several types of immunoevasins, each with a specific function. For example, the MHC Class I immunoevasins prevent the presentation of viral antigens to T Cells, while the MHC Class II immunoevasins inhibit the presentation of antigens to B Cells. Other types of immunoevasins interfere with the function of cytokines.
