Conclusion – Difference Between T Cells and B Cells
The difference between T cells and B cells is evident in their origin and mode of action within the immune system. B and T cells are immune cells that protect us from invading pathogens by adopting different mechanisms. B cells adopt humoral or antibody-mediated immunity (AMI) whereas T cells adopt cell-mediated immunity (CMI) to kill the pathogens. However, the basic principle remains the same, both multiply themselves to kill pathogens. Nevertheless, B cells depend upon T cells for stimulation. They also share some similarities as well.
Difference Between T Cells And B Cells
The difference between T cells and B cells is that the lymphocytes that remain in the bone marrow for differentiation are known as “B-cells,”. In contrast, the lymphocytes that migrate to the thymus are “T-cells.” Their mode of action against fighting pathogens is different. For example- when any pathogen enters the body, T cells recognize it, stimulate different T cells and start making clones. This is how they increase their number and fight against pathogens.
However, the B cells, are first activated by T cells, and they also start multiplying and creating copies of memory B cells and plasma cells that migrate to the infection site (lymph). If the same virus or bacterium re-infects a person, memory B cells can promptly eliminate the antigens.
