Introduction to B Lymphocytes definitions Flashcards

Cells crucial for adaptive humoral immunity, targeting extracellular pathogens using antibodies.

Part of the adaptive immune system targeting extracellular pathogens with B cells and antibodies.

Proteins secreted by plasma cells that bind to antigens to neutralize or destroy pathogens.

Primary lymphoid organ where B cells develop and mature before migrating to secondary organs.

Membrane-embedded receptors on B cells that bind free-floating antigens, also known as BCRs.

A substance that is recognized by the immune system and can provoke an immune response.

Molecules on antigen-presenting cells that display processed antigens to helper T cells.

Cells that assist in activating B cells by recognizing antigens presented on MHC class II molecules.

Effector B cells that secrete large quantities of antibodies to combat immediate threats.

Long-lived cells that respond faster to future infections by remembering the antigen.

Signaling proteins released by cells, such as helper T cells, to activate immune responses.

Specific part of an antigen that is recognized and bound by an antibody or BCR.

Inactive B cells that have not yet encountered their specific antigen.

Identical cells produced from a single B cell after activation and proliferation.

Activated cells that perform a specific immune function, such as plasma cells producing antibodies.
