What does a naive b cell do?

A naive B cell is a type of white blood cell that has not yet been exposed to an antigen. Naive B cells are produced in the bone marrow and circulate in the blood until they encounter an antigen. When a naive B cell binds to an antigen, it becomes activated and begins to divide. The daughter cells of an activated B cell differentiate into plasma cells, which produce antibodies, and memory B cells, which provide long-term immunity.

Here is a more detailed explanation of the function of naive B cells:

* Antigen recognition: Naive B cells express a variety of different surface receptors, called B cell receptors (BCRs). Each BCR is specific for a particular antigen. When a naive B cell binds to an antigen, the BCR sends a signal into the cell, which triggers the activation of the B cell.

* Activation: Activated B cells begin to divide rapidly, producing a large number of daughter cells. These daughter cells differentiate into plasma cells and memory B cells.

* Plasma cells: Plasma cells are antibody-producing cells. They secrete large amounts of antibodies into the blood, which help to neutralize the antigen and clear the infection.

* Memory B cells: Memory B cells are long-lived cells that provide long-term immunity to an antigen. If the same antigen is encountered again in the future, the memory B cells will quickly differentiate into plasma cells, producing a rapid and robust immune response.

Naive B cells are an essential part of the immune system. They provide the body with the ability to recognize and respond to new antigens, and they provide long-term immunity to past infections.
