The WBT is an assay in which the target cells or target components (i.e. cells, liposomes or other cell-like compartments to be lysed) are contacted with appropriately anti-coagulated whole blood from the patient.
WebCytotoxic T lymphocytes (CTLs) often called CD8 + T cells, are a critical component of the adaptive immune system and play an important role in immune defense against intracellular pathogens such as viruses and bacteria and against tumors [ 1 ]. 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 cau…
