BACKGROUND Until now, a lot of effort used to enhance the regenerative potential of stem cells. In this study, we evaluated the hypothesis whether the modulation of autophagy could change differentiation potential of CD146 + cells into mature pericytes, endothelium, and cardiomyocytes descent.
METHOD In this study, CD146 + cells enriched from human bone marrow aspiration and trans-differentiated into mature endothelial cells, pericytes, and cardiomyocytes after exposure autophagy stimulator (50 pM Met) / inhibitor (15-pM HCQ). Protein autophagy protein levels are monitored by western blotting.
NO content measured using the Griess test. Using real-time PCR assay and western blotting, we monitor the rate of descent of proteins and genes. Pro-inflammatory cytokines and angiocrine factors were measured by ELISA. Changes in fatty acids determined by gas chromatography. We also measure exosome secretion capacity by measuring the activity of AChE and real-time PCR.
RESULTS Data revealed the factors modulating autophagy, Beclin-1, P62, and the ratio of LC3-II / I in CD146 + cells differentiate after exposure to the Met and HCQ (p <0.05). Inhibition of autophagy increased NO content compared with Met-treated cells (p <0.05). Real-time PCR analysis showed that treatment with CD146 + cells autophagy modulators alter expression of VE-cadherin, cTnI, and α-SMA (p <0.05). Met increasing the expression of VE-cadherin, α-SMA, and cTnI compared to HCQ-treated cells (p <0.05), while western blotting revealed the protein synthesis of all proteins specific line under the stimulation and inhibition of autophagy.
No statistically significant difference was found in levels of Tie-1, Tie-2, VEGFR-1 and VEGFR-2 after autophagy modulation. Fatty acid profile analysis revealed an increase in polyunsaturated fatty acids after exposure HCQ (p <0.05). Treatment of cells with HCQ increase levels of TNF-α and IL-6 compared with Met-treated cells. The data revealed an increase exosome biogenesis and secretion to the supernatant in cells treated with HCQ compared with Met group (p <0.05).
CONCLUSION In short, the modulation of autophagy could change differentiation potential of CD146 + cells that are important in cardiac regeneration.
Autophagy modulation altered differentiation capacity of CD146+ cells toward endothelial cells, pericytes, and cardiomyocytes.
Iron Deprivation in Human T Cells Induces Nonproliferating Accessories Helper Sel.
Iron uptake via the transferrin receptor (CD71) is an important mechanism for the proliferation of T cells, however, it is not fully understood if targeting CD71 also affect the differentiation and functional polarization of primary human T cells.
In this study, we demonstrated that inhibition of iron consumption by blocking nonproliferating CD71 mAbs to induce T cell, which releases high amounts of IL-2. The target of CD71 by blocking or nonblocking mAbs did not alter the main signal path and the activation of the transcription factor NF-kB, NFAT, or AP-1 as analyzed in Jurkat T cell growth arrest in T cells were deficient in iron (Fe-def) prevented after the addition of exogenous iron in the form of ferric ammonium citrate but not reversible by exogenous IL-2.

Surprisingly, the protein synthesis was found intact in the Fe-def T cells as indicated by the level of comparable CD69 upregulation and cytokine production by T cells enough iron to stimulation with CD3 plus CD28 mAbs. Indeed, the high number of IL-2 was detected in the T cell supernatant Fe-def, which is accompanied by reduced cell surface expression of IL-2R. When we use the Fe-def T cells as in MLRS allogeneic, we observed that these cells acquire the accessory cell function and stimulates the proliferation of bystander T cells by providing IL-2
