Pericytes are integral components of the tissue vasculature and have essential functions in tumour angiogenesis. Endosialin (CD248) is a type I transmembrane glycoprotein highly expressed on pericytes in the tumour vasculature of most solid tumours, however it is low or negligibly expressed on normal tissue pericytes. Experiments using wild-type and endosialin-knockout mice has revealed that stromal endosialin expression facilitates intravasation of tumor cells from the primary tumor into the circulation, thereby promoting metastatic dissemination.

View SamplesLiver sinusoidal endothelial cells (LSEC) constitute discontinuous, permeable microvessels, with a characteristic program of gene expression that differs significantly from continuous microvascular endothelial cells e.g. in the lung. Gata4 is described as master regulator of LSEC specification during liver development. Here, we sought to analyze the role of endothelial Gata4 in the adult liver.

View SamplesReconstitution of cytomegalovirus (CMV)-specific immunity following transplant remains a primary clinical objective to prevent CMV disease, and adoptive immunotherapy of CMV-specific T cells can be an effective therapeutic approach. Due to the persistence of CMV, most CMV-specific CD8+ T cells become terminally differentiated effector cells (TEFF). However, a minor subset retains a memory phenotype (TM). Interestingly, recent studies suggest that CMV-specific CD8+ T cells with different phenotypes may have different abilities to reconstitute sustained immunity following transfer. The immunology of human CMV (HCMV) infections is reflected in the mouse model of MCMV infection. We found that HCMV- and MCMV-specific T cells displayed shared genetic programs, validating the MCMV model for studies of CMV-specific T cells in vivo. After transfer, the proliferative capacity of MCMV-specific TM cells was vastly superior to TEFF cells. Strikingly, TM cells expanded and established sustained and diverse T cell populations even after multiple challenges. Although both TEFF and TM cells could protect Rag-/- mice, only TM cells could consistently survive after transfer into immune replete, latently infected recipients and respond if recipient immunity was lost. These data show that CMV-specific TM cells retain memory function during persistent infection and can re-establish CMV immunity when necessary.
Memory T cells specific for murine cytomegalovirus re-emerge after multiple challenges and recapitulate immunity in various adoptive transfer scenarios.
