The Brain

Subacute sclerosing panencephalitis (SSPE) is a slowly progressing disease of the CNS in children which is caused by measles virus. Ferrets immunized with measles virus prior to inoculation with the cell associated, syncytiogenic D.R. strain of SSPE virus exhibit characteristics very similar to the human disease. Measles virus nucleocapsids are present, high measles antibody titers are found in the sera and inflammatory lesions are prominent in the brains. Measles virus specific immunoglobulin G (IgG) is present in the brain,and IgG/ albumin ratios indicate that the antibodies are synthesized within the CNS.

The Brain

Measles virus specific immunoglobulin G (IgG) has been found in the brains of patients with subacute sclerosing panencephalitis (SSPE), a slowly progressing disease of the central nervous system (CNS) in children. IgG/albumin ratios indicate that the antibodies are synthesized within the CNS. Using the ferret as an animal model to study the disease, we have been attempting to localize the Ig's in the brains of animals inoculated with a cell associated strain of SSPE. In an earlier report, preliminary results using Protein A conjugated to horseradish peroxidase (PrAPx) (Dynatech Diagnostics Inc., South Windham, ME.) to detect antibodies revealed the presence of immunoglobulin mainly in antibody-producing plasma cells in inflammatory lesions and not in infected brain cells.In the present experiment we studied the brain of an SSPE ferret with neutralizing antibody titers of 1:1024 in serum and 1:512 in CSF at time of sacrifice 7 months after i.c. inoculation with SSPE measles virus-infected cells. The animal was perfused with saline and portions of the brain and spinal cord were immersed in periodate-lysine-paraformaldehyde (P-L-P) fixative. The ferret was not perfused with fixative because parts of the brain were used for virus isolation.

Eosinophilic Inclusions

Measles virus is an agent that is capable of replicating in a number of different culture cells and generally causes the formation of multinucleated giant cells. As a result of infection, virus is released from the cells into the culture fluids and reinfection can be initiated by this cell-free virus. The extracellular virus has been examined by negative staining with phosphotungstic acid and has been shown to be a rather pleomorphic particle with a diameter of about 140 mμ. However, no such virus particles have been detected in thin sections of the infected cells. Rather, the only virus-induced structures present in the giant cells are eosinophilic inclusions (intracytoplasmic or intranuclear). These inclusion bodies have been shown to contain helical structures, resembling the nucleocapsid observed in negatively stained preparations.

Kurative Therapie

Das metastasierende Melanom (MM) gehört zu den schwierig behandelbaren Malignomen, wobei Allgemeinzustand und Motivation des Patienten neben Zahl und Lokalisation der Metastasen das therapeutische Vorgehen bestimmen. Solitäre Metastasen in Lunge, ZNS, Weichteilen und Lymphknoten sollten primär chirurgisch entfernt werden. Multiple Metastasen, insbesondere abdominal, werden nur in Ausnahmefällen chirurgisch angegangen. Hier ist vielmehr ein systemische Chemoimmuntherapie angebracht. Aussichtsreiche Behandlungskonzepte beinhalten Interleukin-2, Interferon, und verschiedenen Zytostatika wie DTIC, Temozolamid, Vindesine oder Cisplatin. Bei ZNS- und Skelettfiliae ist die Radiotherapie einzusetzen. Durch diese Chemoimmuntherapien hat sich die Prognose des metastasierenden Melanoms bezüglich des Überlebens verbessert. Langfristig wird aber nur eine Kombination von zeitraubenden Multicenterstudien und experimentellen Ansätzen in der Lage sein, uns langsam an eine kurative Therapie heranzuführen.
