Differences in CD80 and CD86 transendocytosis reveal CD86 as a …
2022年8月23日 · In the presence of CD80, CTLA-4 remained ligand bound, and was ubiquitylated and trafficked via late endosomes and lysosomes. In contrast, in the presence of CD86, CTLA-4 detached in a...
What's the difference between CD80 and CD86? - PubMed
Current perceptions are based around the concept that CD86 is the initial co-stimulatory ligand based on its more abundant and earlier expression pattern; CD80 has a role following antigen-presenting-cell activation.
What's the difference between CD80 and CD86? - Cell Press
CD80 and CD86 expressed by antigen-presenting cells (APCs) have different structural organisations. CD80 is a bivalent dimer (two binding sites) and CD86 is a monomer (single binding site). CD152 is also a bivalent dimer (two binding sites) whereas CD28 is a monovalent (single binding site) dimer.

In the presence of CD80, CTLA-4 remained ligand bound, and was ubiquitylated and trafficked via late endosomes and lysosomes. In contrast, in the presence of CD86, CTLA-4 detached in a pH-dependent manner and recycled back to the cell surface to permit further transendocytosis.
Discovery of CD80 and CD86 as recent activation markers on …
2020年6月24日 · Unexpectedly, CD80 and CD86, normally expressed on antigen-presenting cells, were detected on a subset of activated Tregs, indicating a role for these co-stimulatory molecules in regulating the dynamics of CD4 + T cell responses.
Trans-Endocytosis of CD80 and CD86: A Molecular Basis for the …
2011年4月7日 · Our data suggest a model in which antigen stimulation of either T cells or T reg cells promotes the removal and degradation of CD80 and CD86 from APCs by CTLA-4. To test whether this process could also take place in vivo, we generated a system to study trans-endocytosis in mice.
CD86 Is Associated with Immune Infiltration and Immunotherapy ...
CD86 binds to two ligands on the surface of T cells: the antigen CD28 and cytotoxic T lymphocyte-associated protein 4 (CTLA-4). By binding to CD28, CD86 —together with CD80 —promotes the participation of T cells in the antigen presentation process.

Role of CD80 (B7.1) and CD86 (B7.2) in the Immune Response to …
1998年2月15日 · We demonstrate that whereas infection of human monocytes with viable tachyzoites of Toxoplasma gondii resulted in rapid induction of expression of CD80 and up-regulation of expression of CD86, incubation with killed organisms failed to alter the levels of expression of these costimulatory ligands.
