UNLABELLED Calciphylaxis is a rare and often fatal condition mostly associated with end-stage renal disease. The pathophysiology remains elusive and treatment options are scarce. We present a rare case of severe calciphylaxis after kidney transplantation in a patient with persistent hyperparathyroidism. CASE DESCRIPTION A 78-year-old man with a history of end-stage renal disease developed ede...

Background: A wide variety of cutaneous and mucosal lesions occur in renal transplant recipients. Objectives: Evaluation of the skin and mucous membrane lesions in the kidney transplant recipients in Noor and Ali Asghar Hospital in Isfahan. Patients and Methods: This cross-sectional descriptive study was done on 117 patients (82 male, 35 female), who had received kidney transplants and re...

To understand the cellular mechanism underlying the therapeutic effects exerted by hematopoietic stem cell transplantation in the repair of tissue damage, we investigated the in vivo dynamics of bone marrow (BM) lineage-negative (Lin(-)) cells transplanted into mice with hyper sensitivity dermatitis. Longitudinal in vivo imaging and flow cytometry analyses revealed that Lin(-) cells home direct...

Grafts can be rejected even when matched for MHC because of differences in the minor histocompatibility Ags (mH-Ags). H4- and H60-derived epitopes are known as immunodominant mH-Ags in H2(b)-compatible BALB.B to C57BL/6 transplantation settings. Although multiple explanations have been provided to explain immunodominance of Ags, the role of vascularization of the graft is yet to be determined. ...

A goal of transplantation immunology is to be able to induce antigen-specific tolerance in transplant recipients. In the present study we describe an in vivo model of antigen-specific transplantation tolerance to skin allografts using mice congenic at Qa1, a ubiquitously expressed class I-like molecule encoded to the right of H-2D. B6 mice are deficient in Qa1a-specific T-helper cells and only ...

Background: To examine in an experimental animal study whether alginate microencapsulation of allogeneic parathyroid tissue succeeds by protecting the graft against the host’s activated immune system or by delaying immunization of the host. Methods: Lewis and Dark Agouti rats (n = 200 of each) were used. Parathyroidectomy (PTX) of the hosts was followed by allogeneic transplantation of microenc...

It has been shown in vitro that melanocyte proliferation and function in palmoplantar skin is regulated by mesenchymal factors derived from fibroblasts. In this study, we investigated in vivo the influence of mesenchymal-epithelial interactions in human tissue-engineered skin substitutes reconstructed from palmar- and nonpalmoplantar-derived fibroblasts. Tissue-engineered dermo-epidermal analog...
