  2. Hassall's corpuscles - Wikipedia

    en.wikipedia.org/wiki/Hassall's_corpuscles

    Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.

  3. Thymoma - Wikipedia

    en.wikipedia.org/wiki/Thymoma

    A thymoma is a tumor originating from the epithelial cells of the thymus that is considered a rare neoplasm. [1] Thymomas are frequently associated with neuromuscular disorders such as myasthenia gravis; [2] thymoma is found in 20% of patients with myasthenia gravis. [3] Once diagnosed, thymomas may be removed surgically.

    In the thymus, they undergo a process of maturation, which involves ensuring the cells react against antigens ("positive selection"), but that they do not react against antigens found on body tissue ("negative selection"). [11] Once mature, T cells emigrate from the thymus to provide vital functions in the immune system. [11] [12]

    Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. [1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , which includes histology (the study of the organization of tissues), [ 1 ] and cytology ...

    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.

    English: ThymiStem in collaboration with animator Cameron Duguid have created a beautiful, hand drawn animation explaining the function of the thymus, an essential organ of the immune system. The video shows how T cells, a type of white blood cell, go through a complex journey in the thymus to become mature immune cells ready to fight off ...

    Major function of cTECs is to positively select those T cells that are capable to recognize and interact with MHC molecules on their surface [3]. Once T cell precursors enter the thymic cortex, they start their transformation from double negative stages (T cell without surface expression of CD4 and CD8 co-receptors) to a double positive stage (T cell with surface expression of both co ...

  9. Thymosin - Wikipedia

    en.wikipedia.org/wiki/Thymosin

    Known as "Thymosin Fraction 5", this was able to restore some aspects of immune function in animals lacking thymus gland. Fraction 5 was found to contain over 40 small peptides (molecular weights ranging from 1000 to 15,000 Da.), [ 4 ] which were named "thymosins" and classified as α, β and γ thymosins on the basis of their behaviour in an ...
