What type of cell are plasma cells derived from?

Plasma cells are specialized immune cells that are derived from B cells. When B cells encounter an antigen, they undergo activation and proliferation. Some of these activated B cells differentiate into plasma cells, which are responsible for producing antibodies specific to that antigen. This process is an essential part of the adaptive immune response, enabling the body to mount a targeted defense against pathogens.

Understanding the role of B cells in the immune system is crucial as they are key players in humoral immunity. Plasma cells, as a result of B cell activation, can produce large quantities of antibodies, providing long-lasting immunity and helping to neutralize or eliminate pathogens. This differentiation is fundamental in the context of vaccine responses and natural infections, emphasizing the importance of B cells in maintaining effective immune protection.

The other cell types listed, such as macrophages, T cells, and dendritic cells, have different functions within the immune system and do not directly give rise to plasma cells. Macrophages are primarily involved in phagocytosis and antigen presentation, T cells are key players in cell-mediated immunity, and dendritic cells serve as important antigen-presenting cells that activate T cells. Each of these cell types contributes to the immune response but does so through distinct pathways and mechanisms, highlighting the specialized
