Verified step by step guidance

Understand the role of B cells in the immune response. B cells are responsible for producing antibodies, which are proteins that specifically target and neutralize pathogens.

Recognize the importance of helper T cells in activating B cells. Helper T cells interact with B cells to stimulate their activation, which is a crucial step in the antibody production process.

Learn about antigen-presenting cells (APCs) and their function. APCs, such as dendritic cells and macrophages, present antigens to helper T cells, which is essential for the activation of the adaptive immune response.

Explore the differentiation process of B cells into plasma cells. Once activated, B cells differentiate into plasma cells, which are the cells that actually produce antibodies.

Identify the role of neutrophils in the immune system. Neutrophils are primarily involved in phagocytosis, which is the engulfing and digestion of pathogens, and not directly related to the production of antibodies.
