What is the nonspecific lymphocyte that kills tumor cells and virus infected cells?
Natural Killer Cells
Why do you get sick the first time when you are infected with a pathogen?
Because specialized B cells make antibodies that are effective against that particular invader. Therefore, the first time you are infected, you usually get sick.
What Type of T cell that directly kills virus infected body cells and some tumor cells?
Natural Killer Cells lack the membrane molecules that identify B and T cells, but they have the ability to kill a wide variety of infected body cells and certain tumor cells.
What occurs when pathogens invade the body and what is the response of the body to the invasion?
It depends what sort of pathogen it is and what cells are infected but in general the infected cell is destroyed by lymphocytes and then engulfed by a phagocyte to get rid of what is left.
Are white blood cell pathogen?
No white blood cells are not pathogens, they protect the human body from pathogens.
Infected cells have some of the pathogen's proteins on their surfaces?
true
What are the immune system cells that can recognize and commence an attack on a pathogen that has previously infected the individual?
Memory cells
What is the nonspecific lymphocyte that kills tumor cells and virus infected cells?
Natural Killer Cells
Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
How do helper T cells contribute to the body's defense against pathogens?
Helper T cells help to activate T-cytotoxic cells and B-cells. For instance, if you become infected with a pathogen, a macrophage can consume that pathogen and then present parts of it on its own MHC (Major Histocompatability Complex) receptors. T helper cells then detect this and if this is a pathogen previously encountered, it can stimulate T-cytotoxic cells to begin attacking infected cells, and stimulate B-memory cells to begin rapidly dividing into B-plasma cells to produce anitbodies.

What does T cytotoxic cell do?
A cytotoxic T cell kills cells that have been infected by a virus or bacterium. It does this by puncturing the cell's membrane and by emitting a toxin that kills cells.

What happens when you get infected with pathogen?
i dont know
How does your body protect itself from pathogens?
Firstly if your body gets infected with an unknown pathogen then it will build a memory so next the pathogen that infect the body will automatically eliminated and second how the body gets rid of the pathogen is by sending antibodies or whiteblood cells to kill the invaders

What type of cells kill cancer cells?
I have no idea what kind of cell kills cancer cells. Why do you think i asked the question?
