Lymphocytes that stay in the blood after an infection is gone
Clonal selection of lymphocytes leads to the development of specific effector cells and memory cells. When a lymphocyte recognizes a specific antigen, it proliferates and differentiates into effector cells, such as plasma cells that produce antibodies, or cytotoxic T cells that kill infected cells. Additionally, some of the activated lymphocytes become memory cells, which provide long-lasting immunity by responding more rapidly upon subsequent exposures to the same antigen.

T lymphocytes are characterized by a round or oval nucleus with a small amount of cytoplasm. They have cell surface receptors that can recognize specific antigens presented by antigen-presenting cells. T lymphocytes differentiate into various subsets such as helper T cells, cytotoxic T cells, regulatory T cells, and memory T cells.
Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.

memory cells
Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.
Lymphocytes, particularly memory T cells and B cells, play a crucial role in preventing reinfection by a specific microorganism. After the initial exposure, these cells retain a "memory" of the pathogen, allowing them to recognize it quickly upon subsequent encounters. Memory B cells can swiftly produce antibodies tailored to the pathogen, while memory T cells can enhance the immune response by attacking infected cells. This rapid and targeted response helps to neutralize the pathogen before it can establish a new infection.
Lymphocytes are a type of white blood cell. There are two kinds of lymphocytes. These are the T-cells and B-cells.
