Interleukin 28B

From WikiMD's Wellness Encyclopedia

Interleukin 28B (also known as IL28B) is a protein that in humans is encoded by the IL28B gene. It is a member of the interferon family, which are proteins released by host cells in response to the presence of pathogens such as viruses, bacteria, parasites, or tumor cells.

Function[edit | edit source]

IL28B is involved in immune responses and plays a crucial role in the defense against viral infections. It has antiviral activity and is capable of up-regulating MHC class I molecules, enhancing the presentation of viral antigens to T cells.

Clinical significance[edit | edit source]

Variations in the IL28B gene are associated with different outcomes in diseases such as hepatitis C and HIV. Certain IL28B genotypes are linked to a higher likelihood of spontaneous clearance of hepatitis C virus, as well as a better response to treatment for both hepatitis C and HIV.
