Activity summary

CD16/CD32 also known as FcγRIII and FcγRII are types of Fc gamma receptors. CD16 refers to FcγRIII while CD32 refers to FcγRII. These proteins are involved in binding the Fc region of IgG antibodies. CD16 has a mass of about 50-65 kDa whereas CD32 varies around 40-45 kDa depending on its isoform. These receptors are expressed on the surface of various immune cells like natural killer cells macrophages monocytes and some T cells playing important roles in immune responses.

Biological function summary

CD16/CD32 are critical for mediating antibody-dependent cellular cytotoxicity (ADCC) and phagocytosis. These proteins do not generally form a part of a larger complex but interact directly with immunoglobulins. They enhance the ability of immune cells to clear pathogens and infected cells from the body. These receptors contribute to the activation of signaling pathways that promote the destruction of targets opsonized with antibodies thereby linking adaptive and innate immune responses.

Pathways

These receptors influence the immune signaling cascades such as the NF-kB and MAPK pathways. These pathways are important for inflammatory responses and cellular activation. CD16/CD32 interactions lead to pathways that involve downstream signaling molecules like Syk and PI3K. This allows for immune modulation and assists in communicating between different types of immune responses orchestrating a coordinated attack against pathogens.

Associated diseases and disorders

CD16/CD32 have been connected to autoimmune diseases and certain cancers. These receptors are implicated in disorders like rheumatoid arthritis where their function can become dysregulated contributing to chronic inflammation. In cancers CD16 is important for mediating immune cell interactions in therapies that use antibodies to target cancerous cells. CD32's expression also links to conditions like systemic lupus erythematosus where altered receptor function impacts disease progression often interacting with proteins involved in immune regulation.
