Most of the preprocessing of the T lymphocytes in the thymus Pandemic
Survival Review occurs shortly before birth and a few months after birth. After birth, removal of the thymus gland diminishes but doesn't eliminate the lymphocytic immune system.Removal of the thymus several months before birth can prevent development of all cell mediated immunity. So performing an organ transplant after that time will not result in organ or tissue rejection.
Ten percent of patients with myasthenia gravis have a thymic tumor and 70% have hyperplastic changes (germinal centers) that indicate an active immune response. These are areas within lymphoid tissue where B-cells interact with helper T-cells to produce antibodies.Because the thymus is the central organ for immunological self-tolerance, it is reasonable to suspect that thymic abnormalities cause the breakdown in tolerance that causes an immune-mediated attack on acetylcholine receptors (AChR) in myasthenia gravis.
The thymus contains all the necessary elements for the pathogenesis of myasthenia gravis: myoid cells that express the AChR antigen, antigen presenting cells, and immunocompetent T-cells.Thymus tissue from patients with myasthenia gravis produces AChR antibodies when implanted into immunodeficient mice. However, it is still uncertain whether the role of the thymus in the pathogenesis of myasthenia gravis is primary or secondary.
