However, effects of the immune system on these cells have not been investigated. We have compared the susceptibility of maGSC lines to IL-2-activated natural killer (NK) cells with embryonic stem cell (ESC) lines, iPSCs, and F9 teratocarcinoma cells. The killing of pluripotent cell lines by syngeneic, allogeneic, and xenogeneic killer cells ranged between 48 and 265% in chromium release assays when compared to YAC-1 cells, which served as highly susceptible reference cells. With the exception of 2 maGSC lines, they expressed ligands for the activating NK receptor NKG2D that belong to the RAE-1 family, and killing could be inhibited by soluble NKG2D, demonstrating a functional role of these molecules. Furthermore, ligands of the activating receptor DNAM-1 were frequently expressed. The susceptibility to NK cells might constitute a common feature of pluripotent cells. It could result in rejection after transplantation, as suggested by a reduced teratoma growth after NK cell activation in vivo, but it might also offer a strategy to deplete contaminating pluripotent cells before grafting of differentiated cells.-Dressel, R., Nolte, J., Elsner, L., Novota, P., Guan, K., Streckfuss-Bomeke, K., Hasenfuss, G., Jaenisch, R., Engel, W.

In addition to inflammatory responses of the innate immune system, autoimmune reactions of the adaptive immune system appear to be triggered in subgroups of patients with heart failure as demonstrated by the presence of autoantibodies against myocardial antigens. Moreover, T cell-deficient and T cell-depleted mice have been reported to be protected from heart failure induced by transverse aortic constriction (TAC) and we have shown recently that CD4+-helper T cells with specificity for an antigen in cardiomyocytes accelerate TAC-induced heart failure. In this study, we set out to investigate the potential contribution of CD8+-cytotoxic T cells with specificity to a model antigen (ovalbumin, OVA) in cardiomyocytes to pressure overload-induced heart failure. In 78% of cMy-mOVA mice with cardiomyocyte-specific OVA expression, a low-grade OVA-specific cellular cytotoxicity was detected after TAC. Adoptive transfer of OVA-specific CD8+-T cells from T cell receptor transgenic OT-I mice before TAC did not increase the risk of OVA-specific autoimmunity in cMy-mOVA mice. After TAC, again 78% of the mice displayed an OVA-specific cytotoxicity with on average only a three-fold higher killing of OVA-expressing target cells. More CD8+ cells were present after TAC in the myocardium of cMy-mOVA mice with OT-I T cells (on average 17.5/mm2) than in mice that did not receive OVA-specific CD8+-T cells (3.6/mm2). However, the extent of fibrosis was similar in both groups. Functionally, as determined by echocardiography, the adoptive transfer of OVA-specific CD8+-T cells did not significantly accelerate the progression from hypertrophy to heart failure in cMy-mOVA mice. These findings argue therefore against a major impact of cytotoxic T cells with specificity for autoantigens of cardiomyocytes in pressure overload-induced heart failure."],["dc.identifier.doi","10.3389/fimmu.2018.02665"],["dc.identifier.pmid","30498501"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15720"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59587"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/298"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | D01: Erholung aus der Herzinsuffizienz – Einfluss von Fibrose und Transkriptionssignatur"],["dc.relation","SFB 1002 | C04: Fibroblasten-Kardiomyozyten Interaktion im gesunden und erkrankten Herzen: Mechanismen und therapeutische Interventionen bei Kardiofibroblastopathien"],["dc.relation","SFB 1002 | C05: Bedeutung von zellulären Immunreaktionen für das kardiale Remodeling und die Therapie der Herzinsuffizienz durch Stammzelltransplantation"],["dc.relation","SFB 1002 | S01: In vivo und in vitro Krankheitsmodelle"],["dc.relation.workinggroup","RG Dressel"],["dc.relation.workinggroup","RG Hasenfuß (Transition zur Herzinsuffizienz)"],["dc.relation.workinggroup","RG Toischer (Kardiales Remodeling)"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","610"],["dc.title","CD8+-T Cells With Specificity for a Model Antigen in Cardiomyocytes Can Become Activated After Transverse Aortic Constriction but Do Not Accelerate Progression to Heart Failure"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Similarly to induced pluripotent stem cells (iPSCs), they could provide a source of cellular grafts for new transplantation therapies of a broad variety of diseases. To test whether these stem cells can be rejected by the recipients, we have analyzed whether maGSCs and iPSCs can become targets for cytotoxic T lymphocytes (CTL) or whether they are protected, as previously proposed for embryonic stem cells (ESCs). Results: We have observed that maGSCs can be maintained in prolonged culture with or without leukemia inhibitory factor and/or feeder cells and still retain the capacity to form teratomas in immunodeficient recipients. They were, however, rejected in immunocompetent allogeneic recipients, and the immune response controlled teratoma growth. We analyzed the susceptibility of three maGSC lines to CTL in comparison to ESCs, iPSCs, and F9 teratocarcinoma cells. Major histocompatibility complex (MHC) class I molecules were not detectable by flow cytometry on these stem cell lines, apart from low levels on one maGSC line (maGSC Stra8 SSC5). However, using a quantitative real time PCR analysis H2K and B2m transcripts were detected in all pluripotent stem cell lines. All pluripotent stem cell lines were killed in a peptide-dependent manner by activated CTLs derived from T cell receptor transgenic OT-I mice after pulsing of the targets with the SIINFEKL peptide. Conclusion: Pluripotent stem cells, including maGSCs, ESCs, and iPSCs can become targets for CTLs, even if the expression level of MHC class I molecules is below the detection limit of flow cytometry. Thus they are not protected against CTL-mediated cytotoxicity. Therefore, pluripotent cells might be rejected after transplantation by this mechanism if specific antigens are presented and if specific activated CTLs are present. Our results show that the adaptive immune system has in principle the capacity to kill pluripotent and teratoma forming stem cells. This finding might help to develop new strategies to increase the safety of future transplantations of in vitro differentiated cells by exploiting a selective immune response against contaminating undifferentiated cells.
