Naive T Cells Explained

Humans have a limited supply of naive T cells. Naive T cells are a crucial component of the adaptive immune system, and they play a key role in responding to new infections. Here’s an overview of their characteristics: Development and Source: Naive T cells are developed in the thymus. The thymus is most active during childhood and adolescence, gradually declining in activity and size with age – a process known as thymic involution. Decline with Age: With aging, the production of new naive T cells decreases. This decline is a major factor in the reduced immune responsiveness observed in older…
