✦ Synopsis

Background.

A novel Hodgkin disease (HD)-derived cell line, designated HKB-1, was established from pulmonary HD of nodular sclerosing subtype of a 14-year-old girl. Procedure and Results. Immunophenotypically, HKB-1 cells are of B cell in phenotype, being also positive for markers CD15, CD25 and CD30. Transformation of the cell line by Epstein-Barr virus (EBV) was excluded by failure to detect EBV antigens and EBV DNA in cultured cells. Chromosome studies of HKB-1 showed a pseudodiploid karyotype with com-plex clonal structural aberrations. The detection of a monoclonal immunoglobulin heavy chain (IgH) gene rearrangement confirmed the derivation of the HKB-1 from the B cell lineage and its monoclonality. HKB-1 produced high amounts of interleukin (IL)-6 as detected in culture supernatant whereas no secretion of IL-1beta, IL-2, IL-4, IL-10, IL-12 or interferon (IFN)-gamma was detected. Conclusions. Our studies indicate that this cell line is of tumor origin. Med.

The Src homology 2 domain protein 1A (SH2D1A) is a small, 128-amino acid protein consisting of a single SH2 domain; it is probably involved in signal regulation. It is expressed in activated T and natural killer (NK) cells, but not in B lymphocytes. It was discovered in studies on the rare hereditar

## Abstract Glial cell line‐derived neurotrophic factor (GDNF) has been shown to be neuroprotective in animal models of the dopamine deficiency in Parkinson's disease. To examine the role of the extracellular signal‐regulated kinases 1 and 2 (ERK1/2) in this process, we infused a single dose of GDN
