Popis: |
The Friend virus complex consists of a replication competent virus, the Friend murine leukemia virus (F-MuLV) and a replication defective virus, the Friend spleen focus-forming virus (SFFV). The SFFV defective component is responsible for the induction of acute leukemia in adult mice of susceptible strains [1]. Erythroid cells infected with the polycythemiainducing variant of SFFV (SFFVp) can proliferate and differentiate in the absence of erythropoietin (Epo) whereas the anemia-inducing strain of SFFV renders them hypersensitive to the hormone. The envelope glycoprotein (Env) encoded by SFFV has been shown to be responsible for its biological effect [2].The majority of the SFFVp Env protein remains in the endoplasmic reticulum; however, a small part (3%-5%) is fully glycosylated and reaches the plasma membrane. This fraction transported to the cell surface seems to be essential for erythroblastosis [3,4]. |
