The initiation of cell-mediated immunity to Epstein-Barr virus (EBV) has been analyzed with cells from EBV-seronegative blood donors in culture. The addition of dendritic cells (DCs) is essential to prime naive T cells that recognize EBV-latent antigens in enzyme-linked immunospot assays for interferon gamma secretion and eradicate transformed B cells in regression assays. In contrast, DCs are ...
A cloned line of BALB/c-derived mouse cells (10E2) was used to compare the phenotypic properties of cells transformed either spontaneously, by UV-irradiated herpes simplex virus (UV-HSV), or by SV40. Cells transformed by SV40 (tumorigenic and nontumorigenic) expressed several in vitro properties usu ally associated with transformed cells, including: (a) growth in serum-deficient medium; (b) hig...
The carbohydrate-binding protein, Concanavalin A (Con A), binds to glucose- or mannose-like sites on the cell-surface membrane. Unless the cells are treated with trypsin, this protein agglutinates malignantly transformed cells, but not normal cells. The transformed cells were agglutinated at 24 degrees C but not at 4 degrees C. Transformed and normal cells treated with trypsin were agglutinated...
The Guest Editor introduces the theme papers in this issue, and adds his own thoughts experiences. As he says: "Created by imagination, made real imaginary borders, parks protected areas invite passionate debates about fundamental human rights, individual rights freedoms."
