Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include:
Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells.
Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens.
Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer.
Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer.
Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells.
Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells.
These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
What else can I help you with?
What kills cancer cells by reversing the mutations that caused them to be cancer cells?
One approach is targeted therapy, which uses drugs to specifically target and block the activity of proteins or pathways that are driving cancer growth. Another approach is immunotherapy, which harnesses the body's immune system to recognize and attack cancer cells. Additionally, gene editing technologies like CRISPR are being explored to directly target and correct mutations in cancer cells.
Do target cells of the kidneys respond to LH?
No, target cells of the kidneys do not respond to luteinizing hormone (LH). LH primarily targets the gonads, specifically the Leydig cells in the testes and the theca cells in the ovaries.
How do viruses kill cancer cells?
Viruses can be engineered to specifically target and infect cancer cells, causing them to die. Some viruses can also stimulate the immune system to recognize and attack cancer cells. Additionally, certain viruses have the ability to directly interfere with the replication process of cancer cells, leading to their death.
Cytotoxic T cells can destroy cancer cells by means of a secretion called?
Cytotoxic T cells can destroy cancer cells by means of a secretion called perforin. Perforin is a protein that forms pores in the membrane of target cells, allowing toxic enzymes to enter and induce cell death.
What is progesterone's target cell?
Progesterone's target cells are primarily found in the reproductive system, such as the uterus and mammary glands. In these cells, progesterone plays a key role in regulating the menstrual cycle, supporting pregnancy, and preparing the body for breastfeeding.
Most forms of chemotherapy target which feature of cancer cells?
cell division
How does the combination of artemisinin and iron work together to target cancer cells effectively?
Artemisinin, a compound found in the herb Artemisia annua, can selectively target cancer cells. When combined with iron, artemisinin forms free radicals that specifically attack cancer cells, leading to their destruction. This combination exploits the higher iron levels typically found in cancer cells, making it an effective treatment strategy.
Do b cells destroy cancer cells?
B cells play a role in the immune response against cancer by producing antibodies that can help target cancer cells for destruction by other immune cells. They do not directly destroy cancer cells themselves, but help to coordinate the immune system's response against cancer.

Do target cells of the kidneys respond to LH?
No, target cells of the kidneys do not respond to luteinizing hormone (LH). LH primarily targets the gonads, specifically the Leydig cells in the testes and the theca cells in the ovaries.
What is virotherapy and how does it work?
Virotherapy is a type of treatment that uses viruses to target and kill cancer cells. The viruses are modified to selectively infect and destroy cancer cells while leaving healthy cells unharmed. Once inside the cancer cells, the viruses replicate and cause the cells to burst, ultimately leading to the death of the cancer cells.
How can gamma rays can cause and treat cancer?
Gamma rays can cause cancer by damaging the DNA within cells, leading to uncontrolled growth. In cancer treatment, gamma rays are used in radiation therapy to target and kill cancer cells. The high-energy radiation helps to destroy cancer cells and shrink tumors.
Body cells that react to particular hormone are called?
target cells
How do viruses kill cancer cells?
Viruses can be engineered to specifically target and infect cancer cells, causing them to die. Some viruses can also stimulate the immune system to recognize and attack cancer cells. Additionally, certain viruses have the ability to directly interfere with the replication process of cancer cells, leading to their death.
How is boron used in radiation therapy to target cancer cells?
Boron is used in radiation therapy for cancer treatment through a method called boron neutron capture therapy (BNCT). In BNCT, boron is selectively delivered to cancer cells, which are then exposed to neutron radiation. The boron atoms in the cancer cells absorb the neutrons and release high-energy particles that specifically target and destroy the cancer cells while sparing healthy tissue. This targeted approach helps to minimize damage to surrounding healthy cells and improve the effectiveness of the treatment.
Radiation most likely destroys cancer cells by inducing a process called?
Radiation destroys cancer cells by inducing a process called treatment planning. Treatment planning is essential, because radiation can damage normal cells as well as cancer cells. Radiation therapy uses high-energy radiation to kill cancer cells by damaging their DNA.
What is progesterone's target cell?
Progesterone's target cells are primarily found in the reproductive system, such as the uterus and mammary glands. In these cells, progesterone plays a key role in regulating the menstrual cycle, supporting pregnancy, and preparing the body for breastfeeding.
