Solution
The effects of the secretions of NK (Natural Killer) cells include:
-
Induced inflammation of area around target cell: This is not typically a direct effect of NK cells. NK cells can produce cytokines that promote inflammation, but they do not directly induce inflammation.
-
Creation of pores in the membrane of target cells: This is true. NK cells can release perforin, a protein that creates pores in the target cell's membrane, leading to its destruction.
-
Induced apoptosis of target cell: This is also true. NK cells can induce apoptosis, or programmed cell death, in target cells. They do this by releasing granzymes, enzymes that enter the target cell and trigger apoptosis.
-
Phagocytosis of target cell: This is not typically a direct effect of NK cells. Phagocytosis is usually performed by other immune cells, such as macrophages and neutrophils.
So, the correct answers are "Creation of pores in the membrane of target cells" and "Induced apoptosis of target cell".
