The IFN has no further function beyond this. The model thus provides no approach to circumventing poxviruses decoy receptors that compete with the IFN receptors for IFNs. This simple event has allowed smallpox virus to decimate human populations throughout the ages. We have developed a noncanonical model of IFN signaling that has resulted in the development of small peptide mimetics to both types I and II IFNs. In this report, we focus on a type I IFN mimetic at positions 152 to 189, IFN-\u03b11(152\u2013189), which corresponds to the C terminus of human IFN-\u03b11. This mimetic functions intracellularly and is thus not recognized by the B18R vaccinia virus decoy receptor. Mimetic synthesized with an attached palmitate (lipo-) for cell penetration protects mice from a lethal dose of vaccinia virus, while the parent IFN-\u03b11 is ineffective. Unlike IFN-\u03b11, the mimetic does not bind to the B18R decoy receptor. It further differs from the parent IFN in that it lacks the toxicity of weight loss and bone marrow suppression in mice while at the same time possessing a strong adjuvant effect on the immune system. The mimetic is thus an innate and adaptive immune regulator that is evidence of the dynamic nature of the noncanonical model of IFN signaling, in stark contrast to the canonical or classical model of signaling.<\/jats:p>","DOI":"10.1128\/cvi.00204-14","type":"journal-article","created":{"date-parts":[[2014,6,26]],"date-time":"2014-06-26T02:34:15Z","timestamp":1403750055000},"page":"1178-1184","source":"Crossref","is-referenced-by-count":7,"title":["Type I Interferon Mimetics Bypass Vaccinia Virus Decoy Receptor Virulence Factor for Protection of Mice against Lethal Infection"],"prefix":"10.1128","volume":"21","author":[{"given":"Chulbul M.","family":"Ahmed","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Howard M.","family":"Johnson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","published-online":{"date-parts":[[2014,6,25]]},"reference":[{"key":"key20180919073741_B1","doi-asserted-by":"crossref","first-page":"403","DOI":"10.4049\/jimmunol.114.1_Part_2.403","article-title":"Inhibition of the primary in vitro antibody response of mouse spleen cells by interferon preparations","volume":"114","author":"Johnson","year":"1975","journal-title":"J.
