The presence of high amount of CD1d proteins on the cell surface of NKT cells gives rise to a novel type of NKT cells. This larger amount of CD1d proteins allows the Cd1d high NKT cells to bind more alpha-galactosylceramide molecules and therefore to can produce greater levels of interleukin-4 and INF-gamma molecules leading to possible therapeutical effects<ref name="affinity"/>.

The orientation of the immune pathway (Th1 or Th2) due to the cytokines secretion by NKT cells is dependant of the affinity of the ligand for CD1 molecule. The design of agonists with a higher or lower affinity for CD1 could also leads to therapeutic effects, due to the possibility of specifically directing the immune response towards the Th1 or Th2 pathway <ref name="site"/> <ref> Kishi J, Inuki S, Hirata N, Kashiwabara E, Yoshidome D, Ichihara O, Fujimoto Y.

This Sandbox is Reserved from 26/11/2020, through 26/11/2021 for use in the course "Structural Biology" taught by Bruno Kieffer at the University of Strasbourg, ESBS. This reservation includes Sandbox Reserved 1643 through Sandbox Reserved 1664.
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.
