Dr. Clark has developed a new treatment that stimulates the innate immunity to be more sensitive to cancer cells. Which of the following cells would most likely be stimulated by this new drug?
A) NK cells
B) B lymphocytes
C) Cytotoxic T cells
D) Interferons
Innate Immunity
The first line of defense in the immune system, comprising physical, chemical, and cellular defenses against pathogens.
NK Cells
Natural Killer cells, a type of white blood cell that plays a critical role in the body's immune response by attacking infected or cancerous cells.
Cytotoxic T Cells
Cytotoxic T cells are a type of white blood cell that can directly kill infected cells or cancer cells by recognizing specific antigens on the cell surface.
- Achieve familiarity with the activities and duties of cells associated with adaptive immunity.

Final Answer :
A
Explanation :
NK cells, or natural killer cells, are part of the innate immune system and play a crucial role in the body's first line of defense against tumors and virally infected cells. Unlike B lymphocytes and cytotoxic T cells, which are part of the adaptive immune system, NK cells can respond to and eliminate cancer cells without prior sensitization to specific antigens. Interferons are not cells but proteins that have various immune responses, including antiviral effects.
