Multiple Choice

Which of the following are properties of B cells?

Naive B cells, like naive T cells, can differentiate into effector and memory B cells once activated.

Effector B cells when activated secrete antibodies which fight a novel infection.

Memory B cells when activated secrete antibodies which fight subsequent infections more effectively.

To become activated, a naive B cell must present an immunogenic antigen to an effector CD4 cell.

All are properties of B cells.

Verified step by step guidance

Understand that B cells are a type of white blood cell that play a crucial role in the adaptive immune response.

Recognize that naive B cells, similar to naive T cells, have the potential to differentiate into two main types: effector B cells and memory B cells, upon activation.

Effector B cells, once activated, are responsible for secreting antibodies. These antibodies are crucial in identifying and neutralizing pathogens during an initial infection.

Memory B cells are long-lived cells that, upon re-exposure to the same antigen, can quickly differentiate into effector B cells to produce antibodies, thus providing a faster and more effective response to subsequent infections.

To become activated, naive B cells typically require help from effector CD4 T cells. This process involves the presentation of an antigen by the B cell to the CD4 T cell, which in turn provides necessary signals for B cell activation.
