Difference Between B-Cells and T-Cells
The difference between B cell and T cell table is given below:
Characteristics |
B cells |
T cells |
Another name | B lymphocytes | T lymphocytes |
Maturation | Bone marrow | Thymus |
Percentage in the Blood | 25% of the blood lymphocytes | 75% of the blood lymphocytes |
Lifespan | short | long |
Type of Immunity | Humoral or antibody-mediated immunity (AMI) | cell-mediated immunity (CMI) |
Types | Two types (plasma cells and memory cells) | Three types (helper T cells, cytotoxic T cells, and suppressor T cells) |
Recognition of pathogen | It can recognize both bacterial and viral antigens | It can only recognize viral antigens |
Secretion | Antibodies | Lymphokines |
The movement to the Infected Site | Show movement to the site of infection. | Do not show movement to the site of infection. |
Presence or absence of surface antigens | Absent | Present |
Defend against | The B cells defend against bacteria and viruses in the bloodstream or lymph. | The T cells defend against pathogens including viruses, protists, and fungi that enter the cells in the body. |
Location in lymph nodes | Outside | Inside |
Membrane Receptor | B cell receptor (BCR) | T cell receptor (TCR) |
Inhibitory effect on the immune system | The suppressor cells inhibit the immune system. | They have no inhibitory effect on the immune system |
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.
