Thymus

Thymus

A bilobed organ located in the anterior superior mediastinum, posterior to the sternum and anterior to the great vessels. It is largest during puberty (30-40g) and gradually involutes with age, being replaced by adipose tissue. Each lobe has a cortex (dense with immature T cells) and medulla (Hassall's corpuscles).

कार्य

The primary lymphoid organ responsible for T-lymphocyte maturation and selection. T cells develop from bone marrow precursors and undergo positive and negative selection in the thymus to become immunocompetent while avoiding autoimmunity.

नैदानिक महत्व

Myasthenia gravis is associated with thymic hyperplasia or thymoma; thymectomy can be therapeutic. DiGeorge syndrome involves thymic aplasia and severe T cell immunodeficiency. The thymus involutes with age, contributing to age-related immune decline (immunosenescence).
