Duchenne muscular dystrophy (DMD) is a muscle wasting disease in which inflammation influences the severity of pathology. We found that the onset of muscle inflammation in the mdx mouse model of DMD coincides with large increases in expression of pro-inflammatory cytokines [tumor necrosis factor-α (TNFα); interferon gamma (IFNγ)] and dramatic reductions of the pro-myogenic protein Klotho in muscle cells and large increases of Klotho in pro-regenerative, CD206+ macrophages. Furthermore, TNFα and IFNγ treatments reduced Klotho in muscle cells and increased Klotho in macrophages...

Whether changes in internal body environment affect kidney aging remains unclear. Specifically, it is unknown whether transplanted kidneys from older donors recover from tissue damage after placement in younger recipients. In this study, a parabiosis animal model was established to investigate the effects of a young internal body environment on aged kidneys. The animals were divided into six groups: young (Ycon) and old (Ocon) control groups, isochronic youth-youth group (Y-IP), elderly-elderly group (O-IP) and heterochronic youth (Y-HP) elderly (O-HP) group...

BACKGROUND: There is evidence that NK-cell reactivity might affect graft outcome in transplant recipients and pregnancy in women. METHOD: NK-cell subsets were determined in whole blood using eight-colour-fluorescence flow cytometry in patients before and after renal transplantation, patients with recurrent miscarriage (RM) and healthy controls (HC). RESULTS: Patients late post-transplant (late-Tx) with functioning renal transplants showed abnormally low CD56dimCD16+ NK-cells containing both perforin and granzyme (vs HC p = 0...

Tumour budding and podia formation are well-appreciated in surgical pathology as an aggressive invasion phenotype of colorectal carcinoma cells that is attained in the microenvironment of the invasive margin. In this study, we addressed how tumour budding and podia formation feature in xenografts. Primary colorectal carcinomas (N = 44) of various molecular types (sporadic standard type, high-degree microsatellite-unstable, CpG island methylator phenotype) were transplanted subcutaneously into T and B cell-deficient NSG mice, making possible immunohistochemistry with routine surgical pathology antibodies...

Bone marrow-derived mesenchymal stem cells (BMMSCs) have been consider as a promising therapy in fibrotic diseases. Experimental models suggest that BMMSCs may be used as an alternative therapy to treat chemical- or physical-induced pulmonary fibrosis. We investigated the anti-fibrotic potential of BMMSCs in an experimental model of lung fibrosis by infection with Paracoccidioides brasiliensis. BMMSCs were isolated and purified from BALB/c mice using standardized methods. BALB/c male mice were inoculated by intranasal infection of 1...

PURPOSE OF REVIEW: Overview of neuroendocrine neoplasms in the context of their associations with primary and secondary immunodeficiency states. RECENT FINDINGS: Malignancies of neuroendocrine origin are well known to be associated with hereditary syndromes, including multiple endocrine neoplasia type 1, von Hippel-Lindau syndrome, neurofibromatosis type 1, and tuberous sclerosis. This review includes the X-linked form of hyper-IgM syndrome (XHIGM), due to mutations in the CD40Ligand gene (CD40LG), as an additional inherited disorder with susceptibility to such malignancies, and discusses neuroendocrine tumors (NETs) arising in other immunocompromised states...

Purpose Several open-label randomized studies have suggested that in vivo T-cell depletion with anti-T-lymphocyte globulin (ATLG; formerly antithymocyte globulin-Fresenius) reduces chronic graft-versus-host disease (cGVHD) without compromising survival. We report a prospective, double-blind phase III trial to investigate the effect of ATLG (Neovii Biotech, Lexington, MA) on cGVHD-free survival. Patients and Methods Two hundred fifty-four patients 18 to 65 years of age with acute leukemia or myelodysplastic syndrome who underwent myeloablative HLA-matched unrelated hematopoietic cell transplantation (HCT) were randomly assigned one to one to placebo (n =128 placebo) or ATLG (n = 126) treatment at 27 sites...

Vascularization is one of the hotspots during the development of new therapeutic strategies for bone tissue engineering, which can alleviate hypoxic circumstance and prevent transplant failure. Vascular endothelial growth factor (VEGF) gene transfection using recombinant adenovirus (Ad) vector can effectively promote angiogenesis, but uncontrolled long-term continuous expression of VEGF brings safety concern. Here we constructed a recombinant Ad vector containing nine copies of HRE promoter and the hVEGF165 gene, which conserved the oxygen sensitivity of hypoxia-inducible factor-1/hypoxia response elements (HIF-1/HRE)...

BACKGROUND: Fat grafting is a popular soft tissue filler method; however, its results are variable and technique-dependent. Macrophages are present in fat grafts and closely associated with tissue regeneration. We hypothesized that activation/depletion of early macrophages in transferred fat improves/impairs fat graft survival. METHODS: Mouse inguinal fat (~150 mg) was transferred autologously. Fat grafting was first performed without other manipulations to obtain baseline information...

BACKGROUND: Cell-assisted lipotransfer (CAL) is a process in which fat grafting is supplemented with autologous adipose-derived stromal cells (ASCs). Since the efficacy of the technique was demonstrated, studies have focused on the mechanism by which CAL enhances the rate of graft survival. However, the microenvironmental changes in donor and recipient tissue associated with CAL remain unclear. METHODS: We introduced an animal model of CAL using two different transgenic reporter mice...

BACKGROUND AND AIMS: Altered metabolism is an important regulator of macrophage (MΦ) phenotype, which contributes to inflammatory diseases such as atherosclerosis. Broadly, pro-inflammatory, classically-activated MΦs (CAM) are glycolytic while alternatively-activated MΦs (AAM) oxidize fatty acids, although overlap exists. We previously demonstrated that MΦ fatty acid transport protein 1 (FATP1, Slc27a1) was necessary to maintain the oxidative and anti-inflammatory AAM phenotype in vivo in a model of diet-induced obesity...

This longitudinal single-center study describes the timing and risk factors for genital human papillomavirus (HPV) disease in women after allogeneic hematopoietic cell transplantation (HCT). Between 1994 and 2014, 109 females underwent HCT of whom 82 surviving transplant for >1 year had regular, comprehensive genital tract assessment and treatment of HPV disease. The cumulative proportions of any genital HPV infection at 1, 3, 5, 10 and 20 years were 4.8%, 14.9%, 28.1%, 36.7% and 40.9%, respectively. Demographic, disease-related factors, chronic GvHD (cGvHD) and its treatment were analyzed for their association with persistent, multifocal or severe genital HPV disease...

The infusion of autograft absolute lymphocyte count (A-ALC) and autograft natural killer cells (A-NKC) are prognostic factors for overall survival (OS) and PFS in non-Hodgkin's lymphoma (NHL) patients undergoing autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT). The human monocytic CD14(+)HLA-DR(DIM) cells are associated with worse prognosis in NHL. Thus, we investigated whether the autograft A-NKC/A-CD14(+)HLA-DR(DIM) ratio predicts survival in NHL. In a total of 111 NHL patients, we analyzed apheresis collection samples for the content of A-NKC and A-CD14(+)HLA-DR(DIM)...

Donor-lymphocyte infusion (DLI) for relapse following haploidentical hematopoietic cell transplantation (haploHCT) with post-transplant cyclophosphamide (PTCy) has been described in recipients of bone marrow grafts, but not recipients of G-CSF mobilized peripheral blood (PB) grafts. We retrospectively identified patients who underwent DLI following PB-haploHCT with PTCy for relapse, or loss of chimerism (LOC). Twelve patients (57%) received DLI for hematologic relapse/persistent disease, seven (33%) for extramedullary relapse and two (10%) for LOC...
