First flight. March 1996. Variants. Flight Design MC. The Flight Design CT series is a family of high-wing, tricycle undercarriage, two seat, ultralight and light-sport aircraft produced by Flight Design (Flightdesign Vertrieb) of Germany. The family includes the original CT and the CT2K, CTSW, CTLS and the MC models. [1]
Marmon-Herrington CTLS tanks (a CTLS-4TAC in the foreground and a CTLS-4TAY in the background) in Alaska, summer of 1942. The Marmon-Herrington Combat Tank Light Series were a series of American light tanks / tankettes that were produced for the export market at the start of the Second World War. The CTL-3 had a crew of two and was armed with ...
A cytotoxic T cell (also known as TC, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8+ T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens (such as viruses or bacteria), or cells that are damaged in other ways.

CTL-mediated cytotoxicity. Within the scientific discipline of toxicology, Cytotoxic T lymphocytes (CTLs) are generated by immune activation of cytotoxic T cells (T c cells). They are generally CD8 +, which makes them MHC class I restricted. CTLs are able to eliminate most cells in the body since most nucleated cells express class I MHC molecules.
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.
Community-led total sanitation (CLTS) is an approach used mainly in developing countries to improve sanitation and hygiene practices in a community. The approach tries to achieve behavior change in mainly rural people by a process of "triggering", leading to spontaneous and long-term abandonment of open defecation practices.
Tetramer assay. A tetramer assay (also known as a tetramer stain) is a procedure that uses tetrameric proteins to detect and quantify T cells that are specific for a given antigen within a blood sample. [1] The tetramers used in the assay are made up of four major histocompatibility complex (MHC) molecules, which are found on the surface of ...
Innate resistance to HIV. A small proportion of humans show partial or apparently complete innate resistance to HIV, the virus that causes AIDS. [1] The main mechanism is a mutation of the gene encoding CCR5, which acts as a co-receptor for HIV. It is estimated that the proportion of people with some form of resistance to HIV is under 10%.
