Lymphocytes
Disease-fighting white blood cells produced by the body's immune system. The main types of lymphocytes include: T cells (which attack virus-infected cells, foreign cells and tumor cells), B cells (which produce antibodies and other substances that fight infection, cancer, and other diseases) and natural killer (NK) cells (which attach to and kill abnormal cells like cancer cells).
I have done hours upon hours of research on probiotics and their ability to increase white blood cells (Lymphocytes), among those "T-Cells", Natural-Killer Cells", B-Cells. "Double-Blind" studies can be found at The National Center for Biotechnology Information (NCBI) advances science and health by providing access to biomedical and genomic information.
