The authors describe a strategy for improving the sensitivity of electrochemical immunoassays that is based on the use of hydroxyapatite nanoparticles (HAP-NPs). Signal generation is based on the reaction of phosphate groups present in HAP-NPs with molybdate to form a redox-active molybdophosphate precipitate on the surface of the electrode that facilitates the generation of an electrochemical current...
Background The transcription factor forkhead box P3 (Foxp3) is a master regulatory gene necessary for the development and function of CD4+CD25+ regulatory T cells (Tregs). Mesenchymal stem cells (MSC) have recently emerged as promising candidates for cell-based immunosuppression/tolerance induction protocols. Thus, we hypothesized that MSC-based Foxp3 gene therapy would improve immunosuppressive capacity...
