AbstractHuman delta-like 1 (hDlk1) is known to be able to regulate cell fate decisions during hematopoiesis. Mesenchymal stromal cells (MSCs) are known to exhibit potent immunomodulatory roles in a variety of diseases. Herein, we investigated in vivo functions of hDlk1-hMSCs and hDlk1+hMSCs in T cell development and T cell response to viral infection in humanized NOD/SCID/IL-2Rγnull (NSG) mice. Co-injection of hDlk1-hMSC with hCD34+ cord blood (CB) cells into the liver of NSG mice markedly suppressed the development of human T cells. In contrast, co-injection of hDlk1+hMSC with hCD34+ CB cells into the liver of NSG dramatically promoted the development of human T cells. Human T cells developed in humanized NSG mice represent markedly diverse, functionally active, TCR V$$\upbeta $$ β usages, and the restriction to human MHC molecules. Upon challenge with Epstein-Barr virus (EBV), EBV-specific hCD8+ T cells in humanized NSG mice were effectively mounted with phenotypically activated T cells presented as hCD45+hCD3+hCD8+hCD45RO+hHLA-DR+ T cells, suggesting that antigen-specific T cell response was induced in the humanized NSG mice. Taken together, our data suggest that the hDlk1-expressing MSCs can effectively promote the development of human T cells and immune response to exogenous antigen in humanized NSG mice. Thus, the humanized NSG model might have potential advantages for the development of therapeutics targeting infectious diseases in the future.

Abstract Tumor growth factor β (TGF-β)-induced peripheral regulatory T cells (pTreg) are a promising therapeutic cell source that exhibit Foxp3 expression and suppressive functions similar to natural regulatory T cells. Nonetheless, their clinical potential is limited by the instability of Foxp3 expression and T cell exhaustion that occurs during ex vivo expansion. We postulated that mesenchymal stromal cells (MSCs) could enhance the number, function and Foxp3 expression stability of pTregs during IL-2 driven 21 day expansion due to their diverse immunomodulatory properties. In this study, we observed that use of a human bone marrow mesenchymal stromal cells (hBM-MSC) platform significantly enhanced the number of pTreg during IL-2 driven 21 day ex vivo expansion vs. standard suspension culture condition (MSC platform: 80.2 x 106 vs. IL2/media: 39.3 x 106, n=6; p<0.01). Also the number of pTreg expressing a naive phenotype (CD4+CD45RA+ and CD4+CD62L+ ) were significantly increased (CD45RA+; MSC platform: 74.4 ± 1.6 x 106 vs. IL2/media: 45.9 ± 2.9 x 106, n=6, p<0.001; CD62L+; MSC platform: 79.1 ± 1.3 x 106 vs. IL2/media: 54.5 ± 2.1 x 106, n=6, p<0.001), as well as stability of Foxp3 expression (IL-2/media: 88.2 ± 1.7% vs. MSC platform: 96.2 ± 1.1%, n=7; p<0.05). In addition, pTreg suppressive function was noted to be more potent during 21 day IL-2 driven ex vivo expansion compared to standard IL-2/media culture condition (MSC platform: 79% vs. media: 35% inhibition of T cell proliferation in 10:1 ratio, n=6; p<0.01). pTreg expanded over a hBM-MSC platform exhibited higher surface CD25, CTLA-4, and ICOS MFI expression (CD25; MSC platform: 1410 vs. Media: 774; p<0.001, CTLA-4; MSC platform: 1084 vs. Media: 318; p<0.001, ICOS; MSC platform: 4386 vs. Media: 2641, p<0.01, n=6). Notably, hBM-MSC enhancement of pTreg ex vivo expansion requires direct cell-cell contact, as Foxp3 expression in pTreg was not enhanced by hBM-MSC conditioned media (CM:73.4 ± 6.8% vs. MSC platform: 96.2 ± 1.0%, p<0.001; and IL2/media: 88.8 ± 1.6% vs. MSC platform: 96.2 ± 1.0%, p<0.01) nor in a trans-well culture experiments (Transwell: 83.4 ± 2.5% vs. IL2/media: 88.8 ± 1.6%; and Transwell: 83.4 ± 2.5% vs. MSC platform: 96.2 ± 1.0%, p<0.01). Importantly, optical sectioning microscopy and flow cytometry revealed that hBM-MSC supports Treg number and function via direct contact-dependent mitochondrial transfer (Figure 1A-B). Cytochalasin B treatment blocked mitochondrial transfer, suggesting that tunneling nanotubes (TNT) facilitate mitochondrial transfer from hBM-MSC to pTreg during IL-2 driven ex vivo expansion (Mock: 2208 ± 122.1 vs. Cyto B: 923.8 ± 89 MFI, n=6, p<0.0001). Moreover, the quantity of ATP (n=6; p<0.01) mitochondrial potential of pTreg (MSC platform: 9010 ± 224.5 vs. media: 7316 ± 122.7 MFI, n=6; p<0.01) were significantly enhanced in pTreg during IL-2 driven ex vivo expansion over a hBM-MSC platform. Taken together, hBM-MSC significantly improves the number, maturation, and function of pTreg during 21 day IL-2 driven ex vivo expansion. We have identified one key mechanism of action of hBM-MSC underlying these favorable effects on pTreg during ex vivo expansion to be mitochondrial transfer via TNT. Notably, these studies identify a novel role of hBM-MSC to overcome current limitations in IL-2/media suspension culture conditions including T cell senescence, and loss of Foxp3 expression.

To determine whether the antigen-driven T-cell response is involved in the pathogenesis of aplastic anemia (AA), we examined the complementarity-determining region 3 (CDR3) size distribution of T-cell receptor (TCR) β-chain (BV) subfamilies in the bone marrow (BM) of untreated AA patients. AA patients who did not respond to immunosuppressive therapy and those who obtained unmaintained remission early after cyclosporine (CyA) or antithymocyte globulin (ATG) therapy exhibited essentially a normal CDR3 size pattern. In contrast, five patients who needed continuous administration of CyA to maintain remission exhibited a skewed CDR3 size pattern in a number (>40%) of BV subfamilies suggestive of clonal predominance. The skewing of CDR3 size distribution became less pronounced in one of the CyA-dependent patients when the patient achieved unmaintained remission after a 4-year therapy with CyA, whereas it persisted longer than 7 years in the other patient requiring maintenance therapy. Sequencing of BV15 cDNA for which the CDR3 size pattern exhibited apparent clonal predominance in all CyA-dependent patients showed high homology of the amino acid sequence of the CDR3 between two different patients. These findings indicate that antigen-driven expansion of T cells is involved in the pathogenesis of AA characterized by CyA-dependent recovery of hematopoiesis.

Mesenchymal stromal cells (MSCs) are multipotent cells, which can give rise to several cell types including osteoblasts, adipocytes, and chondroblasts. These cells can be found in a variety of adult and fetal tissues, such as bone marrow, adipose tissue, cord blood, and placenta. In recent years, the biological properties of MSCs have attracted the attention of researchers worldwide due to their potential application for treating a series of clinical situations. Among these properties, special attention should be given to the immunoregulatory potential of those cells. MSCs are able to act on all cells of the immune system, which includes the capacity to inhibit the proliferation and function of T-cells. This feature renders them natural candidates to treat several diseases in which cellular immune response is exacerbated. In this review, we outline the main mechanisms by which MSCs immunosuppress T-cell response, focusing on cell-cell contact, secretion of soluble factors, and regulatory T-cell generation. The influence of surface markers in the immunosuppression process and features of MSCs isolated from different sources are also discussed. Finally, the influences of toll-like receptors and cytokines on the inflammatory microenvironment are highlighted regarding the activation of MSCs to exert their immunoregulatory function.

AbstractThe Wiskott-Aldrich syndrome (WAS) is an X-linked disorder characterized by immune dysfunction, thrombocytopenia, and eczema. We used a murine model created by knockout of the WAS protein gene (WASP) to evaluate the potential of gene therapy for WAS. Lethally irradiated, male WASP— animals that received transplants of mixtures of wild type (WT) and WASP— bone marrow cells demonstrated enrichment of WT cells in the lymphoid and myeloid lineages with a progressive increase in the proportion of WT T-lymphoid and B-lymphoid cells. WASP— mice had a defective secondary T-cell response to influenza virus which was normalized in animals that received transplants of 35% or more WT cells. The WASP gene was inserted into WASP— bone marrow cells with a bicistronic oncoretroviral vector also encoding green fluorescent protein (GFP), followed by transplantation into irradiated male WASP— recipients. There was a selective advantage for gene-corrected cells in multiple lineages. Animals with higher proportions of GFP+ T cells showed normalization of their lymphocyte counts. Gene-corrected, blood T cells exhibited full and partial correction, respectively, of their defective proliferative and cytokine secretory responses to in vitro T-cell–receptor stimulation. The defective secondary T-cell response to influenza virus was also improved in gene-corrected animals.

Introduction. The participation of an inflammatory joint milieu has been described in osteoarthritis (OA) pathogenesis. Mesenchymal stromal cells (MSCs) play an important role in modulating inflammatory processes. Based on previous studies in an allogeneic T-cell coculture model, we aimed at further determining the role of synovial MSCs in OA pathogenesis.Methods. Bone-marrow (BM) and synovial membrane (SM) MSCs from hip joints of late stage OA patients and CD4+ T-cells from healthy donors were analysed regarding surface marker expression before and after coculture. Proliferation upon CD3/CD28 stimulation and cytokine analyses were compared between MSCs.Results. SM-MSCs differed from BM-MSCs in several surface markers and their osteogenic differentiation potential. Cocultures of both MSCs with CD4+ T-cells resulted in recruitment of CD45RA+ FoxP3+ regulatory T-cells. Upon stimulation, only SM-MSCs suppressed CD4+ T-cell proliferation, while both SM-MSCs and BM-MSCs modified cytokine profiles through suppressing IL-2 and TNF-αas well as increasing IL-6 secretion.Conclusions. Synovial MSCs from OA joints are a unique fraction that can be distinguished from their bone-marrow derived counterparts. Their unique ability to suppress CD3/CD28 induced CD4+ T-cell proliferation makes them a potential target for future therapeutic approaches.
