REVIEW
Navneet S Majhail
The prevalence of autologous and allogeneic hematopoietic cell transplantation (HCT) survivors continues to increase. Among patients whose disease remains in remission for the first 2-5years after transplantation, it is estimated that approximately 80-90% will be alive over the subsequent 10years. However, the relative mortality rates of such patients continue to remain higher than those of their general population peers, with late complications contributing to significant long-term morbidity and mortality...

Alginate gels are an outstanding biomaterial widely applicable in tissue engineering, medicine, and pharmacy for cell transplantation, wound healing and efficient bioactive agent delivery, respectively. This contribution provides new and comprehensive insight into the atomic-resolution structure and dynamics of polyvalent ion-crosslinked alginate gels in microbead formulations. By applying various advanced solid-state NMR (ssNMR) spectroscopy techniques, we verified the homogenous distribution of the crosslinking ions in the alginate gels and the high degree of ion exchange...

The development of the eye has been a topic of extensive investigation, from the early studies on tissue induction to more recent breakthroughs in resolving the mechanism regulating progenitor patterning and their gradual and coordinated differentiation into diverse tissue types that function together throughout life. Among the ocular tissue types, the retinal pigmented epithelium (RPE) is at the forefront of developmental biology and stem cell research. The growing interest in this lineage stems from its importance for photoreceptor function as well as from its requirement during embryogenesis for the development of the photoreceptors and the choroid...

The previous literature indicates that patients receiving ongoing care in both Veterans Affairs (VA) and non-VA setting (dual care) may have reduced health outcomes. The objective of this study was to assess the impact of dual care provided to a veteran solid organ transplant population. This was a retrospective cohort study of stable solid organ transplant recipients receiving care at both a Veterans Affairs Medical Center and transplant center. Forty-six veteran organ transplant recipients met inclusion criteria...

Nocardiosis is primarily an opportunistic infection caused by aerobic Gram-positive bacteria of the genus Nocardia. In this case report we describe a male patient who previously received a kidney transplant and was admitted to hospital with chills, headache and pain in the neck and left eye, tremor and coordination problems. A magnetic resonance scan of the brain showed multiple abscesses, and blood culture was positive for Nocardia farcinica. Nocardiosis of the central nervous system is a rare, but serious differential diagnosis in immunosuppressed patients with signs of high intracranial pressure...

Mucopolysaccharidosis type 1 (MPS1) is an inherited lysosomal storage disorder caused by a deficiency in the glycosaminoglycan (GAG)-degrading enzyme α-l-iduronidase (IDUA). In affected patients, the systemic accumulation of GAGs results in skeletal dysplasia, neurological degeneration, multiple organ dysfunction, and early death. Current therapies, including enzyme replacement and bone marrow transplant, improve life expectancy but the benefits to skeletal and neurological phenotypes are limited. In this study, we tested the therapeutic efficacy of liver-directed transplantation of a placental stem cell, which possesses multilineage differentiation potential, low immunogenicity, and high lysosomal enzyme activity...

Neural stem cells have been considered as a source of stem cells that can be used for cell replacement therapies in neurodegenerative diseases, as they can be isolated and expanded in vitro and can be used for autologous grafting. However, due to low percentages of survival and varying patterns of differentiation, strategies that will enhance the efficacy of transplantation are under scrutiny. Here, we have examined whether alterations in Geminin's expression, a protein that coordinates the balance between self-renewal and differentiation, can improve the properties of stem cells transplanted in 6 OHDA hemiparkinsonian mouse model...

Corneal transplantation is among the most prevalent and successful forms of solid tissue transplantation in humans. Failure of corneal allograft is mainly due to immune-mediated destruction of the graft, a complex and highly coordinated process that involves elaborate interactions between cells of innate and adaptive immunity. The migration of immune cells to regional lymphoid tissues and to the site of graft plays a central role in the immunopathogenesis of graft rejection. Intricate interactions between adhesion molecules and their counter receptors on immune cells in conjunction with tissue-specific chemokines guide the trafficking of these cells to the draining lymph nodes and ultimately to the site of graft...

BACKGROUND: IL-17-producing γδT cells (γδT17) promote autoinflammatory diseases and cancers. Yet, γδT17 peripheral regulation has not been thoroughly explored especially in the context of microbiota-host interaction. The potent antigen-presenting CD103(+) dendritic cell (DC) is a key immune player in close contact with both γδT17 cells and microbiota. This study presents a novel cellular network among microbiota, CD103(+) DCs, and γδT17 cells. METHODS: Immunophenotyping of IL-17r(-/-) mice and IL-17r(-/-) IRF8(-/-) mice were performed by ex vivo immunostaining and flow cytometric analysis...
