CTLA-4 is a member of the immunoglobulin superfamily that is expressed by activated T cells and transmits an inhibitory signal to T cells. CTLA-4 is homologous to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA-4 binds CD80 and CD86 with ...
A simple smiley. This is a list of emoticons or textual portrayals of a writer's moods or facial expressions in the form of icons.Originally, these icons consisted of ASCII art, and later, Shift JIS art and Unicode art.
These are most likely due to the breadth of the induced T-cell activation when anti-CTLA-4 antibodies are administered by injection in the blood stream. Using a mouse model of bladder cancer, researchers have found that a local injection of a low dose anti-CTLA-4 in the tumour area had the same tumour inhibiting capacity as when the antibody ...

Ipilimumab, sold under the brand name Yervoy, is a monoclonal antibody medication that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.
The Supplemental Symbols and Pictographs block has 45 emoji that represent people or body parts. These are designed to be used with the set of "Emoji modifiers" defined in the Miscellaneous Symbols and Pictographs block.
The survival of CD25 + CD4 + T reg cells is dependent upon interleukin 2 (IL-2), [4] while in vitro differentiation of T h 3 cells is enhanced by TGF-β, IL-4, and IL-10. Findings suggest that T h 3 cells are a different lineage from naturally arising CD25 + CD4 + T reg cells, but it is still unclear whether T h 3 cells are the same as induced ...
In video games, a bot or drone is a type of artificial intelligence (AI)–based expert system software that plays a video game in the place of a human. Bots are used in a variety of video game genres for a variety of tasks: a bot written for a first-person shooter (FPS) works differently from one written for a massively multiplayer online role-playing game (MMORPG).
