"Memory B cells" of the immune system stay in your body after an infection to enable quick immune responses to the disease-causing organism (antigen) if later exposed again. Antibodies are proteins made by the type of white blood cells called B-cells/"plasma cells" in response to the presence of antigens. The antibodies attach to the B-cells as "B-cell Receptors" to activate them, and can cause them to become either the memory B-cells or more plasma cells.
Radiation can have both suppressive and stimulatory effects on the immune system. In high doses, radiation can damage or kill immune cells, leading to immune suppression. However, at lower doses, radiation can actually stimulate the immune response by promoting the release of immune-stimulating molecules and activating immune cells. The overall impact on immune function depends on the dose, duration, and tissues/organs exposed to radiation.
An auto-immune response.
Crohn's disease is an auto-immune disorder where the immune system attacks the cells of the small intestines. It is treated by monthly infusions of Remicade, which suppresses the immune system.
The body's ability to defend against disease is called as Immunity. There are two types of Immunity. Innate or by birth and which you aqua-ire. Aqua-re has twocomponents1) Humeral 2) cell mediated.
The immune disorder that occurs when the production or activity of immune cells or complement is abnormal is called primary immunodeficiency. It is a group of genetic disorders that affect the immune system's ability to effectively defend the body against infections. This can lead to recurrent or severe infections and other immune-related complications.
Memory cells
pancreatitis
The immune system identifies, remembers, attacks and destroys disease-causing invaders or infected cells.
Auto-immune
White blood cells increase in number to fight an infection or 'disease'. It is part of the body's immune response.
White blood cells, or leukocytes are cells of the immune system involved in defending the body against both infectious disease and foreign materials.
Vaccines work by alerting the immune system to a possibly harmful agent before one is actually exposed to it. The alerted immune system prepares antibodies and in some cases antibody coated T white blood cells that can fight a real infection if later exposed to the actual disease organism. The immune system will remember how to make these antibodies and T cells again if ever needed in the future. Without the vaccine, the infection might be dangerously along in its course before the immune system alerted to it and began to even produce any antibodies, and producing T cells takes even longer.
What does the term "Graft versus host disease" mean? Immunologic reaction involving the attack of host cells by donor immune cells.
in type 1 diabetes, the islet cells of Langerhans, a group of cells in the pancreas that produce insulin, are destroyed.
Radiation can have both suppressive and stimulatory effects on the immune system. In high doses, radiation can damage or kill immune cells, leading to immune suppression. However, at lower doses, radiation can actually stimulate the immune response by promoting the release of immune-stimulating molecules and activating immune cells. The overall impact on immune function depends on the dose, duration, and tissues/organs exposed to radiation.
An auto-immune response.
your body has white blood cells which are built up into a immune system these fight the diseases and vaccines boost the system.
