• B cells, once activated, reproduce to increase in number and secrete large quantities of antibodies to neutralize pathogens.
• B lymphocytes (B cells) differentiate into plasma cells that secrete antibodies upon activation.
• Primary immunodeficiencies result from a defect in one or more elements or functions of the normal immune system, such as T cells, B cells, NK cells, neutrophils, monocytes, antibodies, cytokines, or the complement system.
• B cells develop from stem cells in the bone marrow, where they undergo maturation and training to ensure they do not produce antibodies against healthy tissues.
• When B cells encounter foreign germs (antigens), they mature into plasma cells to produce antibodies or into memory cells to facilitate a rapid response to future infections.
• B cells secrete antibodies to neutralize pathogens.
• B-cells are lymphocytes that arise in the bone marrow and differentiate into plasma cells, which produce immunoglobulins (antibodies).
• B cells, also known as B-lymphocytes or CD19/CD20 cells, are specialized immune system cells that function to produce antibodies (immunoglobulins or gamma-globulins).
• Plasma cells are the mature cells derived from B-cells that produce antibodies.
• Plasma cells are the mature form of B cells that produce antibodies and are located in the spleen and lymph nodes.
• B cells that secrete antibodies are also known as plasma cells.
• B cells produce antibodies that neutralize pathogens and promote their clearance by other immune cells.
• While T-cells kill viruses, they also instruct B-cells to produce antibodies (immunoglobulin).
• Helper T cells assist B cells in producing antibodies and assist killer T cells in attacking foreign substances.
• B cells produce antibodies, which are specialized proteins that recognize and bind to foreign proteins or pathogens to neutralize them or mark them for destruction by macrophages; this response is called humoral immunity.
