T cells, also known as T lymphocytes, are a type of lymphocyte involved in adaptive immunity, specifically cell-mediated immunity. They originate in the bone marrow, mature in the thymus, and recognize antigens presented by MHC molecules.
Las células T, también conocidas como linfocitos T, son un tipo de linfocito que forma parte de la inmunidad adaptativa, específicamente de la inmunidad mediada por células. Se originan en la médula ósea, se desarrollan en el timo y reconocen antígenos presentados por moléculas del complejo principal de histocompatibilidad (MHC).
| Front | One of the two types of antigen-specific lymphocytes responsible for adaptive immune responses, the other being the B cells. These lymphocytes are responsible for the cell-mediated adaptive immune reactions. They originate in the bone marrow but undergo most of their development in the thymus. The highly variable antigen receptor on these lymphocytes recognizes a complex of peptide antigen bound to MHC molecules on cell surfaces. There are two main lineages of these lymphocytes: those carrying α:β receptors and those carrying γ:δ receptors. Some of these lymphocytes activate macrophages, some help B cells produce antibody, and some kill cells infected with viruses and other intracellular pathogens |
