An immune disorder is a dysfunction of the immune system. [1] These disorders can be characterized in several different ways: By the component(s) of the immune system affected; By whether the immune system is overactive or underactive; By whether the condition is congenital or acquired
Immunodeficiency, also known as immunocompromisation, is a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system.
By definition, primary immune deficiencies are due to genetic causes. They may result from a single genetic defect, but most are multifactorial. They may be caused by recessive or dominant inheritance. Some are latent, and require a certain environmental trigger to become manifest, like the presence in the environment of a reactive allergen.
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 ...
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 ...
Immune dysregulation is any proposed or confirmed breakdown or maladaptive change in molecular control of immune system processes. For example, dysregulation is a component in the pathogenesis of autoimmune diseases and some cancers .
These diseases are a set of signs and symptoms characteristic of a particular immune disorder and tend to occur together in people with the same disorder. These disorders include combined immunodeficiencies of T cells and B cells (i.e., gene defects that alter the development and function of the immune system). 3).
A possible definition of Immunopathology is how the foreign antigens cause the immune system to have a response or problems that can arise from an organism's own immune response on itself. There are certain problems or faults in the immune system that can lead to more serious illness or disease.
