WebEarlier we looked at cis- and trans-isomers in square planar platinum complexes. Other transition metal complexes display cis-trans isomerism. Octahedral complexes can also have two particular ligands adjacent to each other or on opposite sides of the metal atom. For example, the cation [ (NH 3) 4 CoCl 2] + has a cis-isomer and a trans-isomer. WebAug 5, 2024 · Therefore, cis interactions between CD2 and its ligands in T cells are required for TCR signaling and T cell activation. Although CD2 can also respond to ligands displayed on APCs, these trans interactions are critical in more limited settings such as cytotoxicity. RESULTS Lack of CD2 broadly compromises T cell responses even in the …
