Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. [1] It is an application of the fundamental research of cancer immunology ( immuno-oncology ) and a growing subspecialty of oncology .
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system.Immunotherapy is designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies.
Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the immune system as a treatment for cancer.
Active immunotherapy is a type of immunotherapy that aims to stimulate the host's immune system or a specific immune response to a disease or pathogen and is most commonly used in cancer treatments. [ 1 ] [ 2 ] Active immunotherapy is also used for treatment of neurodegenerative disorders , such as Alzheimer's disease , Parkinson's disease ...
Cellular adoptive immunotherapy is a type of immunotherapy. Immune cells such as T-cells are usually isolated from patients for expansion or engineering purposes and reinfused back into patients to fight diseases using their own immune system .
Checkpoint inhibitor therapy is a form of cancer immunotherapy. The therapy targets immune checkpoints , key regulators of the immune system that when stimulated can dampen the immune response to an immunologic stimulus.
Cancer Therapy by Inhibition of Negative Immune Regulation (CTLA4, PD1) A2AR & A2BR: The Adenosine A2A receptor is regarded as an important checkpoint in cancer therapy because adenosine in the immune microenvironment, leading to the activation of the A2a receptor, is negative immune feedback loop and the tumor microenvironment has relatively high concentrations of adenosine. [27]
James Allison, now at the University of Texas MD Anderson Cancer Center, was an early pioneer of immunotherapy. He discovered that CTLA-4 inhibits T cells from fully attacking, and hypothesized that blocking CTLA-4 could unleash the immune system to fight cancer. Initially, his idea was met with skepticism, but he continued his research and ...
