Biological Therapy (Immunotherapy)
Biological therapy, also known as immunotherapy, asimmunotherapy, biological response modifier therapy, or biotherapy is a form of treatment that uses the body's immune system to fight cancer. The cells, antibodies, and organs of the immune system of our body are the main defender which work to protect and defend our body against foreign invaders, like bacteria or viruses. Based on research the physicians and researchers have proved that the immune system can also help to both determine the difference between healthy cells and cancer cells in our body, and to eliminate the cancer cells.
Immunotherapy is therapy to repair, stimulate or enhance our own immune system's responses to foreign cells, such as 'cancer'.
Our natural immune system is a highly complex network which is capable of combating a myriad of invaders. Biological therapies use substances those are now clinically produced in the laboratory and are similar to those naturally produced by the immune system,and used for the treatment of cancer. These biotherapy substances are collectively known as biological response modifiers or BRMs. These substances can kill lymphoma cells, decrease their growth rate, or make the patient's own immune system much more active to effectively fight the lymphoma.
How does this therapy works?
Either directly or indirectly these therapies are so desisned to boost the immune system..
It makes foreign cells more recognizable to the immune system so that it can be easily destroyed by the immune system.
Increases the destroying power of the immune system cells.
It changes the way cancer cells grows.
It stops the process that change a normal cell to a cancerous cell
It increases the body's ability to repair or replace normal cells damaged or destroyed by any other forms of cancer treatment like chemotherapy or radiation therapy.
It prevents cancer cells from spreading to other parts of the body.
Role of the immune system in fighting against cancer?
Different types of white blood cells are present in the immune system and each has a different way to fight against foreign or diseased cells, including cancer.
1) lymphocytes : white blood cells, including B cells, T cells, and NK cells.
B cells : This produce antibodies which attack other cells.
T cells : This directly attack cancer cells and send signal to other immune system cells to defend and protect the body.
natural killer cells (NK cells) : This produce chemicals that can bind to and kill foreign invaders in the body.
2) Monocytes : Foreign particles are swallowed and digested by the whte blood cells.
3) Dendritic cells : It gives the foreign cells to the immune system to take care.
B cells, T cells, natural killer cells, and monocytes are types of white blood cells and are present in the blood which circulates to every part of the body which provides protection from cancer and other diseases. Antibodies and cytokines are two types of substances secreted by the cells. Antibodies responds to substances that they recognize as harmful, called antigens. Specific helpful antibodies locks together with specific foreign antigens which form a match. Proteins known as Cytokines are produced by some immune system cells which can directly attack cancer cells. Cytokines are like messengers which communicate with other cells.
Different types of biological therapies
The purpose of Biological response modifiers (BRMs) is to boost, direct or restore the body's ability to fight against certain infection or disease, like cancer. BRMs are produced in a laboratory. Various types of biological response modifiers include:
vaccines
interferons
interleukins
gene therapy
monoclonal antibodies
colony-stimulating factors
nonspecific immunomodulating agents
BRMs can be used alone, in combination of therapies or with traditional radiation and chemotherapy cancer treatments.
