lymphokine-activated killer

Enhanced induction of lymphokine-activated killer activity after lentinan administration in patients with gastric carcinoma.

Lymphokine-activated killer T-cell-originated protein kinase is an enzyme that in humans is encoded by the PBK gene.

It appears to be implicated in immune response associated with natural killer (NK) and lymphokine-activated killer (LAK) cell cytotoxicity.

In cell biology, a lymphokine-activated killer cell (also known as a LAK cell) is a white blood cell that has been stimulated to kill tumor cells.

LAK cells (Lymphokine-activated killer) are a laboratory/clinical subset of NK Cells promoted by IL-2 to attack tumor cells.

For example, chrysotile fibres have been shown to depress the in vitro proliferation of phytohemagglutinin-stimulated peripheral blood lymphocytes, suppress natural killer cell lysis and significantly reduce lymphokine-activated killer cell viability and recovery.
