Background: Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant condition caused by shortened D4Z4 repeat units in the subtelomeric region of 4q35, always on the 4qA haplotype, or due to variants in the SMCHD1 gene leading to hypomethylation of the D4Z4 macrosatellite DNA repeats.

Methods: To explore the potential genetic basis for suspected FSHD presenting with early onset in two siblings without evident family history of the disorder, whole genome sequencing (WGS) and optical genome mapping (OGM) were conducted on the affected individuals and their parents.

Results: The two siblings manifested severe and early-onset clinical features consistent with FSHD, initiating with facial muscle weakness that progressively spread downward since the age of four months.

Background: FLNC gene variants have predominantly been reported in adult populations with cardiomyopathies, and early-onset cases are less common. The genotype-phenotype relationship indicates that dilated cardiomyopathy (DCM) is often associated with FLNC truncating variants.

Methods: We conducted a comprehensive genetic analysis using next generation sequencing (NGS) to identify FLNC variants in patients with cardiovascular conditions.

Allogeneic skin transplantation is an important clinical treatment for many diseases. Although Galectin-9 demonstrates multifaceted roles in modulating immune cell homeostasis and inflammation, its precise impact on balancing effector T cells and Tregs during allogeneic skin transplantation remains uncertain. This work was performed to evaluate the modulation of the survival time of allogeneic skin grafts by Gal-9 and to explore the critical mechanism involved in this process.

Background: Th17 cell differentiation is involved in the development and progression of many diseases, such as rheumatoid arthritis and systemic lupus erythematosus. Present study mainly focused on the role of LINC-XIST in Th17 cell differentiation.

Methods: The naïve CD4+ T cells were isolated from human whole blood.

Sensitized recipients have an increased risk of kidney transplantation due to the immune memory of human leucocyte antigen. They lag on the waiting list and have poorer outcomes of transplantation. The society should give every patient an equal opportunity for treatment.

Background: Kidneys obtained from deceased donors increase the incidence of delayed graft function (DGF) after renal transplantation. Here we investigated the influence of the risk factors of donors with DGF, and developed a donor risk scoring system for DGF prediction.

Methods: This retrospective study was conducted in 1807 deceased kidney donors and 3599 recipients who received donor kidneys transplants in 29 centers in China.

Background: To investigate the application of the superior mesenteric artery (SMA) for the reconstruction of the hepatic artery for liver transplantation, and to improve the success rate and safety of donor liver transplantation.

Methods: The donor liver and the pancreas were obtained, and the SMA and its branches were used to reconstruct the hepatic artery. Liver transplantation was performed after reconstruction to understand the intraoperative situation after donor liver opening, as well as postoperative liver function.

β-poly(L-malic acid) (PMLA) is a water-soluble biopolymer used in medicine, food, and other industries. However, the low level of PMLA biosynthesis in microorganisms limits its further application in the biotechnological industry. In this study, corn steep liquor (CSL), which processes high nutritional value and low-cost characteristics, was selected as a growth factor to increase the PMLA production in strain, Aureobasidium melanogenum, and its metabolomics change under the CSL addition was investigated.

There is no large data analysis reporting the outcome of Chinese kidney transplant patients using mycophenolate mofetil (MMF). This study analyzed 6719 patients from the Chinese Scientific Registry of Kidney Transplantation using MMF, which included 1153 from donation after cardiac death (DCD), 1271 from donation after brain and cardiac death (DBCD), and 4295 from living donor (LD). Compared with the transplants from deceased donor (DD), better outcomes including 3-year graft survival probabilities (LD = 95.

Sirolimus has been shown to ameliorate steroid-resistant rejection and induce long-term immune tolerance among liver transplant patients. However, the detailed mechanism of how Sirolimus achieve these advantages is still lacking. This study attempts to reveal some possible mechanisms by investigating regulatory B cells (Bregs), regulatory T cells (Tregs) and some cytokines in liver transplant recipients whose Tacrolimus was partially converted to Sirolimus.

Follicular helper T cells (Tfh cells) are closely related to the occurrence and development of antibody-mediated rejection (AMR) after renal transplantation. Exosomes play a key role in the rejection after organ transplantation. However, whether Tfh-derived exosomes are involved in AMR has not been reported.

Emerging evidence indicates that natural killer (NK) cells and NKT‑like cells may affect allograft outcomes following solid organ transplantation. However, the roles of these cells in allograft acceptance and dysfunction are controversial. To assess the changes in NK cell and CD3+CD56+ NKT‑like cell frequency and phenotype in renal allograft recipients and to explore their associations with acute T‑cell‑mediated renal allograft rejection (ACR), longitudinal changes in NK and NKT‑like cell frequency and phenotype were characterized using flow cytometry and immunohistochemistry in the peripheral blood and kidney allograft tissues in 142 recipients undergoing kidney transplantation.

Objective: To investigate the characteristics of BK virus (BKV) specific cellular immune response in the recipients who have early infection with BKV after renal transplantation.

Methods: The recipients of renal allografts (n = 30) were divided into groups of BK virus nephropathy (BKVN), viruria, and viremia. The BKV load was observed with real-time fluorescence quantitative polymerase chain reaction in urine and blood every three months.

Nuclear factor κ-light-chain-enhancer of B cells (NF-κB) is one of the most important tumorigenic factors. Although it has been established that NF-κB is overly activated in human glioma cells, the molecular mechanisms that lead to the signal transduction to NF-κB and thereby the induction of resistance to apoptosis remain poorly understood. The present study demonstrated that mRNA and protein levels of E3 ubiquitin-protein ligase 2 (MIB2) were markedly upregulated in glioma cell lines and clinical samples.

The mobilization and homing of endothelial progenitor cells (EPCs) contribute to the rapid endothelialization of tissue engineering blood vessel (TEBV). Inflammation can affect TEBV patency, and monocytes/macrophages (MM) are the main effector cells. But it is not clear how EPCs interact with MM after TEBV transplantation.

Monocytes and macrophages play a key role in defending pathogens, removing the dead cells or cell debris, and wound healing. The mammalian target of rapamycin (mTOR) inhibitor rapamycin (RPM) is widely used in clinics to treat patients with organ transplantation or tumors. The role of mTOR in monocyte/macrophage development remains to be clarified.

Instability and poor targeting causes the long-term patency of RNA-modified tissue engineering blood vessels (TEBVs) remaining unsatisfactory. RNA can be enriched in exosome and then delivered into targeted cells while whether exosome-modified TEBVs achieve RNA targeted delivery is unclear. Here, to promote the expression of klotho protein on the mesenchymal stem cell (MSC)-derived exosomes, klotho plasmids are first transfected into MSCs, and adenosine kinase (ADK) siRNA is then loaded into exosome (klotho/ADK siRNA-exosome) using electrotransfection.

Objectives: As the demand for kidney transplant allografts has increased, many centers are expanding the upper limit of acceptable body mass index for kidney donors. However, obesity is a risk factor for developing renal disease. Our goal was to quantify body mass index trends in donor nephrectomy patients and to institute nutrition counseling to promote sustainable weight loss to reduce the risk of metabolic syndrome-derived renal dysfunction.
