Chronically Activated Lymphocyte

A chronically activated lymphocyte is a lymphocyte that remains in an activated state for a prolonged period due to persistent antigen exposure, dysregulation of signaling pathways, or other factors. This chronic activation can lead to altered function, exhaustion, apoptosis resistance, or pathological proliferation, contributing to diseases such as chronic infections, autoimmune disorders, and hematologic malignancies. Targeting these cells is important for therapeutic intervention in these diseases.
