Stressed-induced thymic involution results in decreased naïve T cell output and compromised host immunity, and is commonly reversible, with recovery of size and …
WebNumerical atrophy: reduction in cell number (e.g., due to apoptosis) Degradation of cytoskeletal proteins occurs via the ubiquitin-proteasome pathway. Electron microscopy shows the presence of autophagosomes. Involution: Organs are temporarily enlarged and then undergo degradation via atrophic processes (e.g., thymus, breast). Senile atrophy WebAge-related regression of the thymus is associated with a decline in naïve T cell output. This is thought to contribute to the reduction in T cell diversity seen in older individuals and linked with increased susceptibility to infection, autoimmune disease, and cancer. Thymic involution is one of the most dramatic and ubiquitous changes seen in the aging …
