검증된 단계별 안내1
Understand the definition of a naive lymphocyte: A naive lymphocyte is a type of immune cell that has fully developed antigen receptors but has not yet encountered an antigen.
Recognize that naive lymphocytes are part of the adaptive immune system and are crucial for responding to new infections.
Identify that naive lymphocytes have not yet been activated by an antigen, meaning they have not yet encountered an antigen that binds to their specific receptors.
Clarify that naive lymphocytes do not produce antibodies until they are activated by an antigen. Antibody production is a function of activated B cells, not naive lymphocytes.
Conclude that the correct description of a naive lymphocyte is that it has fully developed antigen receptors but has not yet encountered an antigen.
