One group of proteolytic enzymes secreted by natural killer (NK) cells is __________.
granzymes
There is no evidence to suggest that natural killer (NK) cells secrete proteolytic enzymes.
NK cells are a type of lymphocyte that plays a crucial role in the innate immune system. They are primarily responsible for the detection and destruction of virus-infected cells and cancer cells. NK cells employ a variety of mechanisms to kill their targets, such as releasing cytotoxic granules containing perforin and granzyme molecules, which induce apoptosis in the target cells. However, these molecules are not considered proteolytic enzymes.
It is important to note that there are other types of immune cells, such as neutrophils and macrophages, that do secrete proteolytic enzymes as part of their immune response.
