CD4 is a co-receptor of the T cell receptor (TCR) and assists the latter in communicating with antigen-presenting cells. The TCR complex and CD4 bind to distinct regions of the antigen-presenting MHC class II molecule. The extracellular D 1 domain of CD4 binds to the β2 region of MHC class II.

Throughout 2020, the source code for several games by Nintendo (as well as console firmware) was leaked by anonymous users on 4chan. These include the first four (and seventh) generations of the Pokémon series and the firmware for the Nintendo 64, GameCube, and 3DS. In 2024, Game Freak was breached for more Pokemon games.
As well as being involved in forming a complex with MHC-II with TCR to control T-cell fate, the CD4 receptor is infamously the primary receptor that HIV envelope glycoprotein GP120 binds to. [6] In comparison, CD28 acts as a ‘co-coreceptor’ (costimulatory receptor) for the MHC-II binding with TCR and CD4. CD28 increases the IL-2 secretion ...
CD4-Ig works by mimicking the binding of CD4 to HIV, thereby preventing the virus from infecting T-helper cells. HIV infects T-helper cells by binding to the CD4 receptor and the co-receptor CCR5 or CXCR4. CD4-Ig binds to the viral envelope glycoprotein gp120, which is responsible for HIV binding to CD4. By binding to gp120, CD4-Ig prevents the ...
In lymphocyte populations, the co-receptor CD4 is found on helper T cells and the co-receptor CD8 is found on cytotoxic T cells. CD4 has four Ig domains in its extracellular portion and functions as a monomer. CD8, in contrast, functions as a dimer with either two identical alpha chains or, more typically, with an alpha and beta chain.
Panda3D is a scene graph engine. [7] This means that the virtual world is initially an empty Cartesian space into which the game programmer inserts 3D models. Panda3D does not distinguish between "large" 3D models, such as the model of an entire dungeon or island, and "small" 3D models, such as a model of a table or a sword.
Free and open-source software portal; Python-Ogre is a Python binding for the OGRE 3D engine, designed to provide the functionality and performance of OGRE (written in C++) with the accessibility and ease of use of Python to facilitate the rapid development of 3D games and to make the OGRE engine more accessible to the beginner, who might otherwise be daunted by the technicalities of writing ...
