Question

Quizplus · Accepted Answer

Granzymes are a group of proteolytic enzymes that are secreted by natural killer (NK) cells. They are important in the killing of infected or cancerous cells, as they are able to induce apoptosis (cell death) in target cells. Selectins are cell adhesion molecules, cytokines are signaling proteins, perforins are pore-forming proteins, and interferons are signaling proteins involved in immune response.
