  • Title: Mouse interferon receptors: a difference in their response to alpha and beta interferons.
    Author: Gordon I, Stevenson D, Tumas V, Natham CR.
    Journal: J Gen Virol; 1983 Dec; 64 ( Pt 12)():2777-80. PubMed ID: 6319561.
    Abstract:
    The interferon receptors of C3H/10T1/2 mouse cells respond differently to alpha and beta interferons under certain conditions. If C3H/10T1/2 cells which have been maintained in logarithmic growth phase are exposed to trypsin or Pronase immediately before they are treated with mouse interferons, they evince an antiviral response to alpha interferon but not to beta interferon. In contrast, contact-inhibited C3H/10T1/2 cells, L-929 mouse cells or human HEL cells lost the ability to respond to both alpha and beta interferons after treatment with trypsin or Pronase. When L-929 cells are incubated at 37 degrees C following exposure to these proteolytic enzymes, they completely regain their ability to respond to mouse beta interferon within 2 h. These observations suggest that the receptors for alpha and beta interferons are different in their topographical distribution in C3H/10T1/2 cells.
