This page is about the immune system. It also tells you about the effects that cancer or treatments may have on the immune system. There is information about. The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. So it is sometimes called the immune response, t-cells and cancer. Cancer can weaken the immune system by spreading into the bone marrow. This happens most often in leukaemia or lymphoma, but it can happen with other cancers too.

The cancer can stop the bone marrow from making so many blood cells. This is because they can cause a drop in the number of white blood cells made in the bone marrow. Cancer treatments that are more likely to weaken the immune system are:. You can find information about the different types of cancer treatments. Some cells of the immune system can recognise cancer cells as abnormal and kill them.

But some new treatments aim to use the immune system to fight cancer. This is also called innate immunity. These mechanisms are always ready and prepared to defend the body from infection.

They can act immediately or very quickly. Certain cancer t-cells and cancer can also overcome these protection mechanisms. Chemotherapy can temporarily reduce the number of neutrophils in t-cells and cancer body, making it harder for you to fight infections.

Radiotherapy to the lung can damage the hairs and mucus producing cells that help to remove bacteria. Your normal neutrophil count is between 2, and 7, per cubic millimetre of blood. This is why you usually only get some infectious diseases, such as measles or chicken pox, once, t-cells and cancer. Vaccination works by using this type of immunity. A vaccine contains a t-cells and cancer amount of protein from a disease.

This is not harmful, but it allows the immune system to recognise the disease if it meets it again. The immune response can t-cells and cancer stop you getting the disease. Some vaccines use small amounts of the live bacteria or virus. These are live attenuated vaccines. Lymphocytes are a type of white blood cells involved in the acquired immune response. There are 2 main types of lymphocytes:. The bone marrow produces all blood cells, including B and T lymphocytes.

B cells mature in the bone marrow. But T cells mature in the thymus gland. Once they are fully mature, the B and T cells travel to the spleen and lymph nodes ready to fight infection, t-cells and cancer.

B cells react against invading bacteria or viruses by making proteins called antibodies. The antibody made is different for each different type of germ bug. The antibody locks onto the surface of the invading bacteria or t-cells and cancer. Antibodies can also detect and kill damaged cells.

The B cells are part of the memory of the immune system. They are able to make their antibody very quickly. Antibodies have 2 ends. One end sticks to proteins on the outside of white blood cells.

The other end sticks to the germ or damaged cell and helps to kill it. The end of the antibody that sticks to the white blood cell is always the same. Scientists call this the constant end. The end of the antibody that recognises germs and damaged cells varies, t-cells and cancer, depending on the variant of p53 and bladder cancer it needs to recognise. So it is called the variable end.

Each B cell makes antibodies with a different variable end from other B cells. Cancer cells are not normal cells. So some antibodies with variable ends recognise cancer cells and stick to them. It uses natural body substances, or drugs made from natural body substances, to treat cancer. They are helpful t-cells and cancer cancer treatment because cancer cells are different from normal cells.

And the immune system can recognise and kill abnormal cells. Scientists can produce, in the laboratory, different chemicals that are part of the immune response. Skip to main content.
