Therefore, we asked whether TCR expressed by CIK cells could mediate Ag-specific …
Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water. It occurs in a hypotonic environment, where water moves into the cell by osmosis and cause… WebAs shown in Figure 95.6, cytolytic function was demonstrable when freshly isolated unfractionated cell populations from the reproductive tract were cultured overnight in medium containing low concentrations of IL-2 before use in an antigen-independent anti-CD3 mAb-mediated lysis assay system to measure cytolytic potential.
