Background

Interferon alpha 2 is a type 1 interferon secreted by virus-infected cells to protect surrounding cells from the pathogen. Recombinant human interferon alpha 2 has been approved for therapeutic application in a range of human oncological and viral diseases. Three Interferon alpha 2 subvariants (2A, 2B, 2C) differ by only one or two amino acids at positions 23 and/or 34 of the mature protein (PMID: 25982860; 10672347; 1694761)
