3Which of the following cell types is NOT involved in innate immunity?Select one alternative:NeutrophilMast cellNatural killer cellPlasma cell

Break Down the Problem

1. Identify the different cell types listed.
2. Determine the role of each cell type in the immune system, particularly in innate immunity.

Relevant Concepts

• Innate Immunity: This is the first line of defense against pathogens and involves cells that respond quickly to infections, including physical barriers and immune cells like neutrophils, mast cells, and natural killer (NK) cells.
• Adaptive Immunity: This involves a more specific response and includes cells like plasma cells, which are responsible for producing antibodies.

Analysis and Detail

1. Neutrophils: A type of white blood cell that is part of the innate immune system. They are one of the first responders to sites of infection.
2. Mast Cells: These are also part of the innate immune system. They play a role in allergy and defense against pathogens.
3. Natural Killer Cells: These are a component of innate immunity as well, involved in the destruction of virus-infected cells and tumor cells.
4. Plasma Cells: These are derived from B cells in the adaptive immune response and are responsible for producing antibodies.

Verify and Summarize

• Neutrophils, mast cells, and natural killer cells are all involved in innate immunity.
• Plasma cells are not involved in innate immunity; instead, they are part of the adaptive immune response.

Final Answer

Plasma cell is the cell type NOT involved in innate immunity.
