In most cases, the evolution of the disease and its morbid anatomy suggests an immune deficiency state in which an abnormal clone of intestinal plasma cells incapable of producing the complete IgA molecule proliferates, perhaps in response to microbial antigenic stimulation. In the majority of cases, this proliferation is composed of mature appearing plasma cells which lack morphologic features of malignancy. Although possibly reversible, this proliferation appears to be highly susceptible to the evolution of secondary neoplastic clones, which appear in most instances after a clinical course of unpredictable duration and manifest themselves in the form of single or multiple immunoblastic sarcomas.</p>","PeriodicalId":73191,"journal":{"name":"Hamatologie und Bluttransfusion","volume":"18 ","pages":"377-82"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12008748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular hybridizations between BLV-3H cDNA and several viral RNAs show that BLV is not related to Mason-Pfizer Monkey Virus (MPMV) Simian Sarcoma Associated Virus (SSV-1) Feline Leukemia Virus (FeLV) or Avian Myeloblastosis Virus (AMV).

The high preference of BLV reverse transcriptase for Mg++ as the divalent cation suggests that BLV might be an atypical mammalian leukemogenic type C virus.

Not only the more primitive BFU-E shows hormone-independency (18). This phenomenon is in favour of the view that the Rauscher virus induced erythroblastosis is a true neoplasia although transplantation experiments failed so far. The experiments in which transformation in vitro of B.M. cells by RLV is established (19) show that the CFU-E can serve as a target for the virus. Treatment of normal mice with CFA leads to a rapid increase in CFU-E in the bone marrow (18). Splenomegaly of RLV-infected mice is enhanced by CFA-treatment probably due to an increase in targets. Transfection with proviral DNA also can transform the CFU-E of BALB-c mice. This approach allows in vitro studies on the resistence of mouse strains to RLV in vitro. The studies are of interest for the human disease in two aspects. In vitro transformation assays are needed to study the oncogenic potential of putative human leukemia viruses. Furthermore the studies have yielded some new insight in the pathogenesis of virally induced erythroblastosis.
