t cells
When abnormal cells divide and create other abnormal cells, it can lead to the formation of a tumor or mass of cells. This can result in the growth of cancer or other diseases if left unchecked. Additionally, these abnormal cells may also spread to other parts of the body through a process called metastasis.
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.
Abnormal multiplication of the body's cells is known as cancer. Cancer occurs when cells divide uncontrollably and can invade surrounding tissues. This can lead to the formation of tumors and disrupt normal body functions. Treatment options for cancer include surgery, chemotherapy, and radiation therapy.
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.
Pathogens such as bacteria, viruses, and fungi can directly attack human tissue by invading and replicating within the cells or tissues of the body. This invasion can lead to damage of the host tissue, triggering an immune response and causing symptoms of infection.
The disease characterized by the unrestrained growth of abnormal cells in or on tissues of the body is known as cancer.
The immune system of the body provide a defense against abnormal cells and pathogens inside living cells. Generally this results into rise in temperature of the body. Therefore, fever is the indication of having war against abnormal cells and pathogens.
Helper cells (e.g. T helper cells) play a role in activating the immune response by coordinating and stimulating other immune cells like killer cells (e.g. cytotoxic T cells) to target and destroy abnormal cells. Killer cells directly eliminate infected or abnormal cells by inducing programmed cell death. This coordinated effort helps the immune system effectively rid the body of threats.
No form of cancer is contagious. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow and causgees large numbers of abnormal blood cells to be produced and enter the blood. Even if your body would come into contact with one of these abnormal cells, it would simply attack the cell and get rid of it with white blood cells, the body's defense team.

Additionally, these abnormal cells may also spread to other parts of the body through a process called metastasis.
No, antibodies don´t attack T-cells, there is an autoimmune disease called antiphospholipd abtibody syndrome which is an autoimmune disorders occur if the body's immune system makes antibodies unable to recognize the foreign agent that might be harmful to cells and makes the T-cells attack and damage tissues or cells.
Yes, you would have a higher than normal WBC count. The common increase would be in in what are called Natural Killer (NK) lymphocytes. There are 3 functional classes of lymphocytes: 1. T cells (cell-mediated immunity) attack foreign cells directly 2. B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies 3. Natural killer (NK) cells detect and destroy abnormal tissue cells such as cancers You could say that the NK's are trying their best for the body by killing as many abnormal (cancer) cells as possible.
Cytotoxic T cells kill infected or abnormal cells by releasing toxic substances that puncture the cell membrane, triggering cell death.
T cells are responsible for recognizing and targeting infected or abnormal cells in the body. They play a key role in coordinating the immune response by directly killing infected cells or by helping other immune cells to mount an effective attack against pathogens. T cells also contribute to long-term immunity by forming memory cells that remember specific pathogens for faster response upon reinfection.
