the T cells produces cytokinesis and cleaves the antigens

A white blood cell that releases chemicals that kill pathogens?
cytotoxic T-cells
A large white blood cell that can destroy substances such as cell debris dust pollen and pathogens by the process of phagocytosis?
All of them!
What do killer t cells do?
Destroy pathogens
Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
What is the role of T cells in a human body?
T cells are part of the adaptive immunity. There are two major types of T cells: CD4+ T helper cells and CD8+ T cytotoxic cells. T helper cells primarily function in humoral immunity whereas T cytotoxic cells are important in cell mediated immunity. T helper cells produce cytokines to activate other immune system components like macrophages, B cells, etc. whereas T cytotoxic cells primarily kill infected cells.
Which type of white blood cell that surrounds and kills invading cells removes dead cells and stimulates the action of other immune cells?
Macrophages, sometimes called phagocytes, engulf pathogens and cell debris and trigger T-cells and B-cells.
A white blood cell that releases chemicals that kill pathogens?
cytotoxic T-cells
What directly attacks and lyses cellular pathogens?
The cytotoxic t cell directly attacks and lyses cellular pathogens. They are activated by antigens that stimulate an immune response.
What kind of cell can engulf bacteria or make antibodies?
Inside the human body, a particular type of white blood cell called a macrophage will engulf and digest bacteria.
What is the job of a macrophage?
They are used in the first (primary) line of the immune response. These are NOT SPECIALIZED phagocytes, as you can tell, carry out their function via phagocytosis. They engulf bacteria in various ways, but usually just grab the bacteria, engulf it, let it die, and then they die. Helper T and Antibodies mark viruses and bacteria that get past these for destruction. The macrophages recognize the bacteria, and engulf them. Their primary role is to engulf bacteria. They are non-specific.
What is the function of a t-cells?
T cells destroy pathogens.
What is the function of T-helper cells?
T cells destroy pathogens.
What is the function of the T helper cells?
T cells destroy pathogens.
A large white blood cell that can destroy substances such as cell debris dust pollen and pathogens by the process of phagocytosis?
All of them!
How do T cells destroy infected or diseased cells?
Cytotoxic T-cells kill infected cells in one of two ways: 1. By interaction with Fas ligand on T-cell with Fas molecule on target cell (induces apoptosis). 2. Release of lytic granules containing granzymes (also induces apoptosis) - For this, the T-cell needs to form pores in the target cell using perforin and granulysin.
What do killer t cells do?
Destroy pathogens
Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
