Type 1 diabetes (T1D) is an autoimmune disease resulting from inflammatory destruction of islets β-cells. Nowadays, progress in cell therapy, especially mesenchymal stem cells (MSCs) proposes numerous potential remedies for T1D. We aimed to investigate the combination therapeutic effect of these cells with insulin and metformin on neuropeptide Y, melanocortin-4 receptor, and leptin receptor genes expression in TID. One hundreds male rats were randomly divided into seven groups: the control, diabetes, insulin (Ins.), insulin+metformin (Ins.Met.), Wharton's Jelly-derived MSCs (WJ-MSCs), insulin+metformin+WJ-MSCs (Ins.Met.MSCs), and insulin+WJ-MSCs (Ins.MSCs). Treatment was performed from the first day after diagnosis as diabetes. Groups of the recipient WJ-MSCs were intraportally injected with 2× 10⁶ MSCs/kg at the 7th and 28th days of study. Fasting blood sugar was monitored and tissues and genes analysis were performed. The blood glucose levels were slightly decreased in all treatment groups within 20 Our data exhibit that infusion of MSCs and its combination therapy with insulin might ameliorate diabetes signs by changing the amount of leptin and subsequent changes in the expression of neuropeptide Y and melanocortin-4 receptor.

Cytokines have regulatory crosstalk with CMV infection leading to manage of post-liver transplantation virus-related outcomes. To investigate the link between IL-21, IL-23 and IL-27 mRNA and protein level with active CMV infection, which was evaluated in reactivated and non-reactivated liver transplant recipients. Two groups of liver transplant recipients were enrolled in this study-54 without and 15 with active CMV infection. 3 EDTA-treated blood samples were taken on day 1, 4, and 7 post-liver transplantation. Plasma and buffy coats of all samples were separated. All samples were analyzed for CMV reactivation using antigenemia technique. The separated plasma of positive samples was used for viral DNA extraction and protein evaluation. For evaluating the mRNA expression level by real-time PCR, RNA extraction and cDNA synthesis were done for all samples. Also, the protein level of studied genes was estimated by ELISA. The expression level of IL-21, IL-23A and IL-27A cytokine genes was increased in CMV reactivated liver transplant recipients in comparison with CMV non-reactivated ones; IL-27A expression pattern was significant (p=0.001) at all sampling times. IL-21 significantly increased on the 2 Elevation in the expression level of IL-21, IL-23A and IL-27A mRNA and protein level in CMV reactivated patients emphasized on the antiviral role of these cytokines in CMV reactivated liver transplant recipients.
