Question

Quizplus · Accepted Answer

Plasma cells are activated by antigens, which are foreign substances that can elicit an immune response from the body. When an antigen enters the body, it is recognized by B cells, which can then differentiate into plasma cells that produce antibodies specific to that antigen. This process is known as the humoral immune response. T cells and APCs are involved in the cellular immune response, while memory cells are produced after an initial immune response and can quickly respond to a subsequent exposure to the same antigen.
