Memory Cells

Question

Memory cells
A) are found exclusively within the nonspecific immune cells/processes.
B) are produced only by B cells.
C) increase the response time to an antigen.
D) store IgG, IgE, and IgA.

Accepted Answer

Memory cells are specialized immune cells that are formed after an initial exposure to an antigen. They remain in the body and can quickly recognize and respond to the same antigen if encountered again. This response time is faster than the initial response, which can help the body to more effectively fight off the infection or disease. Memory cells are not exclusive to nonspecific immune cells/processes and are produced by both B cells and T cells. Memory cells do not store antibodies, but instead, they quickly differentiate into antibody-producing plasma cells upon encountering the antigen again.
