Fisiopatologia. — Membrane vesicles, shed from in vitro cultured human breast carcinomas cells, inhibit lymphocytes proliferation.
1994
Membrane vesicles are released by the cells of the two human breast carcinoma cell lines 8701-BC and MCF-7. Vesicles express on their surface HLA Class I molecules and tumor associated antigens and they appear to have a strong, dose dependent, inhibitory effect on thymidine incorporation by periferal lymphocytes. Inhibition is evident on both PhA stimulated or non stimulated lymphocytes. The inhibitory effect is visible after three days of culture. Vesicle addition does not cause cytotoxic effects since inhibited lymphocytes are still capable to exclude Trypan blue. No apoptoptic cells were observed.
Membrane vesicles shed into the extracellular medium by human breast carcinoma cells carry tumor-associated surface antigens.
1995
We have compared the pattern of surface antigen expression, as detected by monoclonal antibodies (mAbs), in plasma membranes vs shed membrane vesicles of two human breast carcinoma cell lines, MCF-7 and 8701-BC. Antigen expression was detected on cells by immunofluorescence (IF) analysis, whilst, due to their small dimensions, the same technique was not applicable to vesicles. For these structures dot-blot analysis and immunoelectron microscopy (IEM) were employed. When applicable, both cell membranes and membrane vesicles were immunoprecipitated and the precipitate (IP) was analyzed by SDS-PAGE. Cells of both lines expressed HLA class I antigens, epithelial cytokeratins, β1 integrins, CEA …
