MICROANATOMY

Detailed explanation-1: -Natural killer cells (NK cells) are white blood cells that destroy infected and diseased cells, like cancer cells. They’re also a type of lymphocyte, like B-cells and T-cells. NK cells can destroy harmful cells in the early stages, preventing viruses and cancer cells from spreading.

Detailed explanation-2: -Killer T cells kill the body’s own cells that have been invaded by the viruses or bacteria.

Detailed explanation-3: -Here, we consider how interferons enhance the activity of natural killer cells (NK cells), which are part of the innate immune system. Like cytotoxic T cells, NK cells destroy virus-infected cells by inducing the infected cell to kill itself by undergoing apoptosis.
