body's defense system responding to a perceived threat

Immune activation refers to the process by which the body's immune system is triggered to respond to a perceived threat, such as an infection, injury, or foreign substance. This involves the activation of immune cells like T-cells and B-cells, which then work to identify, attack, and eliminate the threat. In the context of alopecia, immune activation can mistakenly target hair follicles, leading to hair loss.
