Bcellekloner

Bcellekloner refers to genetically identical B cells that arise from a single parent B cell. This process, known as clonal expansion, is a critical component of the adaptive immune system's response to pathogens. When a B cell encounters its specific antigen, it becomes activated and undergoes rapid proliferation. This results in a large population of B cells, all expressing the same B cell receptor and therefore recognizing the same antigen.

These B cell clones serve multiple purposes. Some differentiate into plasma cells, which are specialized antibody-producing factories. The antibodies secreted by these plasma cells are crucial for neutralizing or marking pathogens for destruction by other immune cells. Other B cell clones differentiate into memory B cells. These memory cells persist in the body long after the infection has been cleared, providing a faster and more robust immune response upon subsequent exposure to the same antigen. This immunological memory is the basis for vaccination. The selective expansion of specific B cell clones is essential for mounting an effective and targeted immune defense.
