Webb1 dec. 2009 · Both canonical T cell thymus-trafficking molecules and T cell gut-trafficking molecules are implicated in tGVHD. A number of T cell–trafficking molecules have been implicated in GVHD. We assessed a subset of these molecules, including CCR9, L selectin, α E and β 7 integrin subunits, P selectin glycoprotein ligand-1 (PSGL-1), CCR2, and … WebbIntroduction Thymus and activation-regulated chemokine (TARC) was first identified and cloned from phytohemagglutinin-stimulated peripheral blood mononuclear cells by Imai …

Webb1 juli 2024 · Thymic blood vessels at the perivascular space (PVS) are the critical site for both homing of hematopoietic progenitor cells (HPCs) and egress of mature thymocytes. It has been intriguing how different opposite migrations can happen in the same place. WebbFinally, progenitors in blood must settle in the thymus.
