Study with Quizlet and memorize flashcards containing terms like From an immunologic perspective, cancer cells can be viewed as altered self cells that have escaped normal growth-regulating mechanisms.
Sep 2, 2024 · T-cells play a vital role in the immune response against cancer cells. CD8+ T-cells, also known as cytotoxic T lymphocytes (CTLs), directly kill infected or cancerous cells by recognizing antigens presented on MHC class I molecules. They induce apoptosis in target cells, effectively eliminating them.
Study with Quizlet and memorize flashcards containing terms like how do cancer cells grow?, what types of cells are present in tumors?, how does the body prevent cancer? and more.
They play a central role in initiation of the tumor-specific immune response. These cells take up tumor-associated proteins, process them, and present the TAAs to T cells to stimulate the CTL response against tumor. Several classes of dendritic cells can mediate tumor promotion or suppression.

The immune system protects the body against illness and infection that bacteria, viruses, fungi or parasites can cause. It is a collection of reactions and responses that the body makes to damaged cells or infection. So it is sometimes called the immune response. The immune system is important to people with cancer because: 1. cancer can weaken the...
Cancer can weaken the immune system by spreading into thebone marrow. The bone marrow makes blood cells that help to fight infection. 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. Certain cancer treatments can temporarily weaken the im...
Some cells of the immune system can recognise cancer cells as abnormal and kill them. But this may not be enough to get rid of a cancer altogether. Some treatments aim to use the immune system to fight cancer. There are 2 main parts of the immune system: 1. the protection we have from birth (in built immune protection) 2. the protection we develop ...
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). This in built protection comes from: 1. a barrier formed by the skin around the body 2. the inner linings of the gut and lungs, which produce mucus and trap invading bacteria 3. hairs tha...
Neutrophils are a type of white blood cell that are very important for fighting infection. They can: 1. move to areas of infection in the body 2. stick to the invading bacteria, viruses or fungi 3. swallow up the bacteria, viruses or fungi and kill them with chemicals When you don't have enough neutrophils in your blood, doctors may say that you ar...
This is immune protection that the body learns after having certain diseases. The body learns to recognise each different kind of bacteria, fungus or virus it meets for the first time. So the next time the same bug invades the body it is easier for the immune system to fight it. This is why you usually only get some infectious diseases such as meas...
Lymphocytes are a type of white blood cells involved in the acquired immune response. There are 2 main types of lymphocytes: 1. B cells 2. T cells The bone marrow produces all blood cells, including B and T lymphocytes. Like the other blood cells, they have to fully mature before they can help in the immune response. B cells mature in the bone marr...
