Thymus Degeneration and Regeneration - PMC - National Center …
Sep 1, 2021 · Chemotherapy profoundly impairs thymus function by causing thymus atrophy, reducing T lymphocytes, shrinking the thymic lobules, and decreasing the production of naïve T cells (72, 73).
Health Consequences of Thymus Removal in Adults
Aug 2, 2023 · Thymus atrophy begins in infancy and is markedly accelerated in puberty, and it results in an exponential decline in new T-cell generation. 8,9 With declining central T-cell production, the...
Thymic involution - Wikipedia
Thymus involution is one of the major characteristics of vertebrate immunology, and occurs in almost all vertebrates, from birds, teleosts, amphibians to reptiles, though the thymi of a few species of sharks are known not to involute.
Thymus: The Function of the Gland & Why it is Important - Cleveland Clinic
Your thymus is a small gland in the lymphatic system that makes and trains special white blood cells called T-cells. The T-cells help your immune system fight disease and infection. Your thymus gland produces most of your T-cells before birth.
Age‐related thymic involution: Mechanisms and functional impact
The thymus is the primary immune organ responsible for generating self‐tolerant and immunocompetent T cells. However, the thymus gradually involutes during early life resulting in declined naïve T‐cell production, a process known as age‐related thymic involution.
Thymus and aging: morphological, radiological, and functional …
Jul 23, 2013 · The thymus is a primary lymphoid organ responsible for the production of immunocompetent T cells and, with aging, it atrophies and declines in functions. Universality of thymic involution in all species possessing thymus, including human, indicates it as a long-standing evolutionary event.
Thymus Atrophy - an overview | ScienceDirect Topics
Atrophy of the thymus, the primary site of T lymphocyte generation, is a hallmark of the aging immune system. Age-associated thymic atrophy results in diminished output of new, naïve T cells, with immune sequelae that include diminished responses to novel pathogenic challenge and vaccines, as well as diminished tumor surveillance.
Thymus Atrophy - an overview | ScienceDirect Topics
Thymus atrophy refers to the condition where the thymus gland experiences a decrease in size and function due to either a lack of T lymphocytes from the bone marrow or destruction of lymphocytes within the thymus itself.
Effect of Stress on the Thymus - News-Medical.net
Aug 23, 2021 · Stress-induced thymic atrophy. Various physiologic conditions including malnutrition, emotional distress, pregnancy, or pathologic conditions like infection, disease, cancer treatments, or...
The thymus road to a T cell: migration, selection, and atrophy
Aug 27, 2024 · We discuss the occurrence of acute thymus atrophy in response to systemic inflammation. The thymus demonstrates high plasticity, shaping inflammation by abrogating T cell development and undergoing profound structural changes, and facilitating regeneration and restoration of T cell development once inflammation is resolved.
