  • polypeptide
  • The two 5-proximal ORFs encode the replicases, two internal ORFs encode movement proteins, and the 3-proximal ORF encodes a polypeptide (p37) which plays a dual role as capsid protein and as suppressor of RNA silencing. (jove.com)
  • gene
  • To date, several host- and virus-related factors have been implicated in the progression to MCII, such as the virus-induced expansion of selected subsets of B-cell clones expressing discrete immunoglobulin variable (IgV) gene subfamilies, the involvement of complement factors and the specific role of some HCV proteins.

  • bind
  • In line, HBsAg preferentially bound to TLR9-triggered pDC demonstrating that once pDC are able to bind HBV/HBsAg, the virus exerts its immune regulatory effect. (jove.com)
  • complexes
  • In particular, about 60% of HCV-infected patients present cold-precipitable (cryoprecipitable) and noncryoprecipitable immune complexes that could be associated with the clinical onset of type II mixed cryoglobulinemia (MCII) [ 2 ]. (mdpi.com)
  • This immune complex-mediated vasculitis is characterized by a primary B-cell clonal proliferation accompanied by the deposition of immune complexes composed of complement factors, mono/oligoclonal IgMs with rheumatoid factor (RF) activity bound to oligo/polyclonal IgGs that, in the case of HCV infection, are mostly directed against HCV proteins [ 3 ].
