Zusammenfassung
Introduction: The cell-surface glycoprotein CD26 has multiple functions including dipeptidyl aminopeptidase (DPP IV) activity, delivery of co-stimulatory T cell activation signals and binding of adenosine deaminase (ADA). ADA displays immunoregulatory functions by inhibiting adenosine which can deliver negative signals on various immune cells. High levels of CD26 can be found on activated T cells and CD26 expression has been linked to autoimmune diseases. The role of the CD26/ADA/adenosine system in regulating immune responses in liver diseases is completely unknown. Methods: We studied CD26 expression on PBMC s…
