The immune system is a network of biological systems that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to bacteria, as well as cancer cells, parasitic worms, and also objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major ...
2017 – First autologous CAR T-cell therapy tisagenlecleucel approved for the treatment of pediatric B-ALL; second autologous CAR T-cell therapy axicabtagene ciloleucel (Yescarta) is approved. 2020 – The first mRNA vaccines ( BNT162b2 , mRNA-1273 ), are developed for SARS-CoV-2 infection; this new technology completed design, testing, and ...
Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...
Primary immunodeficiencies are disorders in which part of the body's immune system is missing or does not function normally. [1] To be considered a primary immunodeficiency (PID), the immune deficiency must be inborn, not caused by secondary factors such as other disease, drug treatment, or environmental exposure to toxins.
Transferred components are immune cells and autologous as above. [ 1 ] [ 2 ] Transfer of immune cells is made between different individuals of monozygotic twins in human or of the same pure line in experimental animals from immunologically sensitized to naive host, where transferred cells are engrafted without rejection or GVHD in the new host.
The immune system may respond in multiple ways to an antigen; a key feature of this response is the production of antibodies by B cells (or B lymphocytes) involving an arm of the immune system known as humoral immunity. The antibodies are soluble and do not require direct cell-to-cell contact between the pathogen and the B-cell to function.

Immunosenescence is the gradual deterioration of the immune system, brought on by natural age advancement. A 2020 review concluded that the adaptive immune system is affected more than the innate immune system. [1] Immunosenescence involves both the host's capacity to respond to infections and the development of long-term immune memory.
