Its clinical spectrum ranges from severe classical to milder nonclassical or late-onset phenotypes. Renal involvement, termed Fabry Nephropathy (FN), can vary from mild proteinuria to kidney failure. FN diagnosis, especially in nonclassical cases with a genetic Variant of Unknown Significance (VUS) in the GLA gene, poses challenges. Measurement of plasma lyso-Gb3 levels is gaining importance in FN diagnosis, while renal biopsy with electron microscopy remains the gold standard in equivocal cases. Treatment options include Enzyme Replacement Therapy (ERT) and chaperone therapy, demanding careful candidate selection due to high treatment costs. Research has predominantly focused on classical FD, revealing modest treatment benefits. However, evidence for treating patients, especially females, with milder nonclassical or late-onset phenotypes is scarce, emphasizing the necessity for placebo-controlled clinical trials in these subgroups. Meanwhile, participation in global FD registries can improve our understanding of disease management. Case Presentation: A woman in her late sixties presented with moderate chronic kidney disease, mild proteinuria, and microscopic hematuria. Her family history included a prevalence of renal, cardiac and cerebrovascular diseases. Kidney biopsy revealed characteristic myelin figures and zebra bodies in podocytes, strongly suggestive of FN. Genetic analysis identified a VUS in the GLA gene (c.655A > C, p.Ile219Leu), introducing diagnostic uncertainty. Further investigations revealed severe cardiac involvement. Considering the recurring difficulty presented by the finding of a VUS in the GLA gene during FN assessments, along with the uncertainty regarding the need for treatment in nonclassical or late-onset FD phenotypes, especially in women, this case becomes a central focus for a thorough review of the literature. This review aims to propose a practical algorithm that integrates clinical, biochemical, and genetic markers for FN screening and diagnosis. Additionally, it explores treatment benefits in nonclassical or late-onset FD phenotypes, with a focus on female patients.展开更多

For most of these applications, systemic delivery of the cells is preferred. However, this requires the homing and migration of MSCs to a target tissue. Although MSC hominghas been described, this process does not appear to be highly efficacious because only a few cells reach the target tissue and remain there after systemic administration. This has been ascribed to low expression levels of homing molecules, the loss of expression of such molecules during expansion, and the heterogeneity of MSCs in cultures and MSC culture protocols. To overcome these limitations, different methods to improve the homing capacity of MSCs have been examined. Here, we review the current understanding of MSC homing, with a particular focus on homing to bone marrow. In addition, we summarize the strategies that have been developed to improve this process. A better understanding of MSC biology, MSC migration and homing mechanisms will allow us to prepare MSCs with optimal homing capacities. The efficacy of therapeutic applications is dependent on efficient delivery of the cells and can, therefore, only benefit from better insights into the homing mechanisms.展开更多
