Question

Which of the following process provides a defense against abnormal cells and pathogens inside living cells: Nonspecific response, Inflammatory response, Humoral immunity, or Cell-mediated immunity? HELLLPPP!?

Answer 1

Both nonspecific response and cell-mediated immunity.

Explanation:

First, it is important to know there are three lines of defense in a human body:

1. barriers such as the skin and mucosa
2. innate immunity; the nonspecific response.
3. adaptive immunity; the specific response.

To attack pathogens inside cells and abnormal (cancer) cells, the body can use the second and third lines of defense.

Second line of defense
The nonspecific response is the 'quick and dirty' response (innate). Natural Killer cells are part of this second line of defense and are able to kill cells that are infected with viruses for example. They are also able to kill abnormal cells.
Note that this is a form of cell-mediated immunity!

Third line of defense
The adaptive immune response is slower but more specific. For your question the cell-mediated response is important. The so called cytotoxic T-cells are able to recognize infected cells and cancer cells.

Conclusion: the `color(red)"cell-mediated response"` provides the defense against intracellular pathogens and abnormal cells. This involves both the nonspecific as the specific immune system.
