How Does the Adaptive Immune Response Work

Unlike the innate immune system, which attacks only based on the identification of general threats, the adaptive immunity is activated by exposure to pathogens, and uses an immunological memory

What are the three phases of adaptive immune response?

Three main phases encompass the immune response that is orchestrated by antigen-specific T cells: expansion, contraction and memory (see Fig.

What activates the adaptive immune system?

To achieve functional adaptive immune responses, antigen-specific T cell populations are stimulated by professional antigen-presenting cells like dendritic cells (DCs), which provide crucial stimulatory signals for efficient expansion and development of effector functions.
