9 results about "Memory T cell" patented technology

Memory T cells are a subset of infection- and cancer-fighting T cells (also known as a T lymphocyte) that have previously encountered and responded to their cognate antigen; thus, the term antigen-experienced T cell is often applied. Such T cells can recognize foreign invaders, such as bacteria or viruses, as well as cancer cells. Memory T cells have become "experienced" by having encountered antigen during a prior infection, encounter with cancer, or previous vaccination. At a second encounter with the invader, memory T cells can reproduce to mount a faster and stronger immune response than the first time the immune system responded to the pathogen that entered the body. This behaviour is utilized in T lymphocyte proliferation assays, which can reveal exposure to specific antigens.
