AB Despite significant advances in treatment, the aetiology of Hodgkin's
disease has remained elusive. While epidemiology has uncovered the
likely infectious nature of the malignancy, neither the causative agent
nor the cell of origin have been identified. The available
epidemiological, histological and molecular biological evidence were
reviewed and the following conclusions reached. Hodgkin's disease is
probably an infectious, but not contagious disease, and is compounded by
immunodeficiency. The suspected role of the Epstein-Barr virus (EBV) as
causative agent has been substantially weakened, although a role as
co-factor is likely. A prime candidate for the cell of origin seems the
interdigitating reticulum cell (IRC). Reed-Sternberg cells found in
patients with Hodgkin's disease may represent in vivo hybridomas of the
IRC with B- and/or T-cells. As IRC is unlikely to be susceptible to EBV,
a retrovirus may be the culprit. Hybridomas may be formed when
retroviral antigens expressed by a macrophage cell attract reactive B-
and T-cells and, instead of an immune reaction, fusion occurs. Further
research is necessary in the search for the causative agent of Hodgkin's
disease.
