Memory B-Lymphocyte

Long-lived B-lymphocytes that have previously encountered an antigen, allowing for a faster and more robust antibody response upon subsequent exposure to the same antigen.

Key Functions:

• Provides long-term humoral immune memory.
• Rapidly differentiates into plasma cells and produces antibodies upon re-exposure.
• Crucial for acquired immunity.

Interacting Systems & Components:

• B-lymphocyte (type of)
• Immune System (component of adaptive immunity)
• Antigen (remembers)
• Antibody (produces)
• Plasma Cell (differentiates into)
