Memory cells are created by B lymphocytes (B cells), which are part of the immune system.
The Role of B Lymphocytes in Memory Cell Creation
B lymphocytes are crucial in the adaptive immune response. Their primary function is to produce antibodies that target and neutralize pathogens like viruses. After an initial infection, some activated B lymphocytes differentiate into memory cells.
- Function of Memory Cells: These memory cells "remember" the specific pathogen encountered during the initial infection.
- Faster Response: If the same pathogen invades the body again, memory cells trigger a faster and more robust antibody production compared to the initial response.
How B Lymphocytes Create Memory Cells: An Example
Imagine the body is infected with a specific virus.
- Initial Infection: B lymphocytes recognize the virus.
- Activation and Differentiation: Some B lymphocytes become plasma cells, which produce antibodies to fight the infection. Others become memory cells.
- Future Infection: If the same virus attacks again, the memory cells quickly recognize it and rapidly produce antibodies, often preventing or minimizing the severity of the illness.

Cell Type | Function |
---|---|
B Lymphocytes | Produce antibodies; Create memory cells for long-term immunity. |
Memory Cells | Remember specific pathogens; Initiate rapid antibody production upon re-exposure. |
