By maintaining this balance, Tregs protect healthy tissue from damage caused by an overzealous immune system, playing a critical role in preventing chronic inflammatory diseases. Upon re-encountering the same antigen, they can proliferate and differentiate into effector cells much faster than during the primary response, often neutralizing the threat before symptoms develop.
The Journey of Lymphocyte Development in the Thymus and Bone Marrow
This classification is determined by where the cells mature—T cells in the thymus and B cells in the bone marrow—along with the specific receptors they use to detect threats. Unlike T and B cells, NK cells recognize and eliminate cells that are missing normal "self" markers or that display signs of stress, such as virus-infected cells or tumor cells.
When a B cell encounters its specific antigen, it becomes activated and differentiates into plasma cells, which mass-produce antibodies tailored to that antigen. Additionally, some activated B cells become long-lived memory cells, ensuring a rapid antibody response if the same invader is encountered again in the future.
Where T Cells and B Cells Mature: Thymus vs. Bone Marrow
B Lymphocytes: The Antibody Factories B cells are the humoral immunity specialists, responsible for producing antibodies that neutralize pathogens in bodily fluids. This rapid recall is what makes long-term immunity possible.
More About Types of lymphocyte
Looking at Types of lymphocyte from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on Types of lymphocyte can make the topic easier to follow by connecting earlier points with a few simple takeaways.
