The branches reach the thymus and travel with the septa of the capsule into the area between the cortex and medulla, where they enter the thymus itself; or alternatively directly enter the capsule. [2] The veins of the thymus, the thymic veins, end in the left brachiocephalic vein, internal thoracic vein, and in the inferior thyroid veins. [2]
A thymectomy is an operation to remove the thymus. It usually results in remission of myasthenia gravis with the help of medication including steroids. However, this remission may not be permanent. Thymectomy is indicated when thymoma are present in the thymus. Anecdotal evidence suggests MG patients with no evidence of thymoma may still ...
Thymulin (also known as thymic factor or its old name facteur thymique serique) is a nonapeptide produced by two distinct epithelial populations in the thymus first described by Bach in 1977. [1] It requires zinc for biological activity. Its peptide sequence is H-Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH.

TECs, as a component of the thymus, play a key role in thymocyte development and self-tolerance, so their dysfunction causes many autoimmune diseases, tumors of immunodeficiencies. Most frequently are occurred epithelial tumors established from TEC and thymocytes - thymomas and thymic carcinoma.
Thymectomy is the surgical removal of the thymus gland. Thyroidectomy is the removal of all or part of the thyroid gland. Tonsillectomy is the removal of the tonsils. Trabeculectomy is the removal of part of the eye's trabecular meshwork as a treatment for glaucoma. Tumorectomy is the surgical removal of a tumor.
On MRI, ectopic cervical thymus appears as a homogeneous mass which is isointense to muscle on T1-weighted scans and hyperintense on T2-weighted scans. [3] Biopsy or histological examination upon resection can also be used to make a definitive diagnosis. [6] [9] Sometimes, ectopic thymus is found incidentally during neck surgery. [6]
Second, a thymus transplantation can cause a non-donor T cell-related GVHD because the recipients thymocytes would use the donor thymus cells as models when going through the negative selection to recognize self-antigens, and could therefore still mistake own structures in the rest of the body for being non-self. This is a rather indirect GVHD ...
