What are the cells called that police the body in blood and lymph to kill cancer cells and virus infected body cells?

The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.


How do CD8 T cells kill infected cells in the immune response process?

CD8 T cells kill infected cells by releasing proteins called perforins and granzymes. Perforins create pores in the infected cell's membrane, allowing granzymes to enter and trigger cell death. This process helps eliminate the infected cell and stop the spread of the infection.


In cell meditated immunity what binds to and tears open the cell membranes of invading cells or infected body cells?

T Cytotoxic Cells destroy infected body cells by making holes in the cell membranes using proteins called perforins. This allows water to rush into the cells, causing it to burst. They are actually called Killer T cells.


What substances do T cells produce to destroy cells infected by a virus?

T cells produce cytokines, such as interferons and interleukins, that help enhance the immune response against virus-infected cells. They also release cytotoxic substances, like perforin and granzyme, which can directly kill infected cells. Additionally, T cells can activate other immune cells, like macrophages, to help eliminate virus-infected cells.


What blood cells enter infected cells?

White blood cells


What kills cells infected with a pathogen?

Cells infected with a pathogen can be killed by the immune system through mechanisms such as releasing toxic chemicals, inducing programmed cell death (apoptosis), or activating immune cells like T cells and natural killer cells to target and destroy the infected cells.


Which of HIV infected cells are capable of crossing the blood brain barrier and infecting the brain with HIV?

Infected CD4 T-cells


How does a common cold virus affect the nose?

the cold virus attaches itself to the lining of the nasal passages and sinuses. This causes the infected cells to release a chemical called histamine. Histamine increases the blood flow to the infected cells, causing swelling, congestion


What are cytotoxic T cells for?

they are in our bodies to attack and kill infected cells!


Which blood cells kill the infected blood cells in the bodys?

-White blood cells White blood cells are like policemen in bloodstream. They are constantly on patrol for infected cells. (Yes; they usually eat them -aka kill them.)


How do cytotoxic T cells kill infected or abnormal cells in the body?

Cytotoxic T cells kill infected or abnormal cells by releasing toxic substances that puncture the cell membrane, triggering cell death.


What Type of T cell that directly kills virus infected body cells and some tumor cells?

Cytotoxic T cells (CD8+ T cells) are responsible for directly killing virus-infected body cells and some tumor cells by releasing cytotoxic molecules like perforin and granzymes. They recognize infected or abnormal cells by recognizing antigens presented on the cell surface.
