Transfection of Siglec-5 into primary human T lymphocytes leads to decreased proliferation. Freshly isolated human PBMCs were labeled with CFSE and nucleofected with Siglec-5 expression plasmid. A, Siglec-5 expression in nucleofected cells was detected by flow cytometry using an anti–siglec-5 Ab. B, Cell proliferation was analyzed by comparing CFSE content in cells nucleofected with Siglec-5 plasmid versus cells nucleofected with no plasmid (Neg control). C, CFSE profile of cells within the population of nucleofected cells that were expressing Siglec-5, compared with the CFSE profile of cells within the same population that were not expressing Siglec-5. Data shown are representative of two independent experiments.
