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.
What do killer t cells do?
Destroy pathogens
How do killer cells work?
Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
Do red blood cells attack viruses that cause an illness?
No. red blood cells carry oxygen. White blood cells attack pathogens such as viruses.
Can all white blood cells attack any kind of pathogen?
No, the white blood cells are divided into many types of specialized cells. The Macrophages, Granulocytes, Natural Killer cells and Dendritic (Lagerhans) cells are part of the immuno response system's first line of defense: Macrophages kill any type of pathogens they recognize as not welcome, while the Neutrophile Granulocytes are experts in bacteria killing. Dendritic cells alert the adaptive immuno response system such as T-cells. Cytotoxic T-cells then kill tissue cells infected by pathogens, and so does Natural Killer cells (but does not touch the pathogens themselves). They do not have to be activated first, but are able to find infected/sick cells by themselves, which makes them effective cancer-killers. Also, by killing infected cells they prevent growth and proliferation of more pathogens in the body. Regulatory-T-cells (suppressor cells) and T-Helper cells does not kill pathogens themselves but regulate the rest of the white blood cells.
What disease causes the body to attack pathogens and its normal cells?
Auto-immune
One way white blood cells can protect the human body from pathogens?
they attack it
Which cells in the immune system identify pathogens and distinguish one pathogen form another?
T cells
Which cells in the immune system identify pathogens and distinguish one pathogen from another?
B cells and Helper T cells
