Human umbilical cord derived mesenchymal stem cells alleviate T1DM model via TGFBI-mediated T cells proliferation

Wu Chushan , Xu Tingting , Li Lu , zheng Rongxiu

Type 1 diabetes mellitus is autoimmune T cells mediated destruction of β-cells. Mesenchymal stem cells (MSCs) are considered a promising treatment for T1DM due to the strong immunosuppressive and regenerative capacity. However, the comprehensive mechanism is still unclear. Our previous study indicated that the transforming growth factor beta-induced gene (TGFBI) is highly expressed in human umbilical cord derived mesenchymal stem cells (hUC-MSCs), which is also implicated...

Evaluation of Toll-like Receptor 2 Expression on T Lymphocytes in Patients with Graves' Disease in Relation to the Clinical Parameters

Klatka Maria , Grywalska Ewelina , Polak Agnieszka

Introduction: Graves'disease (GD) is a polygenic and multifactorial disease.The innate immune system is a complex network of structured cells and proteins, including the Toll-like receptors (TLRs), which are also expressed on the cells of the adaptive immune system.The aim was to assess the relationship between the expression of TLR-2 on the surface of T CD4+ and CD8+ lymphocytes in pat...

Effects of methimazole therapy on effector T and B regulatory cells in pediatric patients with Graves' disease

Stożek Karolina , Grubczak Kamil , Starosz Aleksandra , Bossowski Filip , Moniuszko Marcin , Bossowski Artur

Introduction: The incidence of autoimmune thyroid diseases (ATD) is constantly rising. Graves’ disease (GD) remains the most common cause of thyrotoxicosis in pediatric population, but the exact pathogenesis of GD is still not fully understood. The immunological basis of ATD assumes an imbalance between effector and regulatory T lymphocytes. B regulatory cells (Breg) are able to suppress the pro-inflammatory properties of effector T cells. Methimazole (M...

T- and B-Lymphocytes Levels in Children with Type 1 Diabetes in Association with Candida Infection

Elkina Stanimira , Blajeva Svetla , Halvadzhiyan Irina , Botzova Venetziya , Petrova Chayka

Although type 1 diabetes (T1D) is most common autoimmune chronic metabolic disease in childhood, data about the role of T-Lymphocytes (T-Ly) and B-Lymphocytes (B-Ly) in children after the diabetes onset are still controversial. The aim of the study was to evaluate the serum levels of T– and B-Ly in children with T1D as a predisposing factor for genital candidiasis (GC).Material: We studied 71 children with T1D at the age of 6 to 18 years, divided in...

The Association between rs4684677 T/A Polymorphism in Preproghrelin Gene And predisposition to Autoimmune Thyroid Diseases in Children*

Bosswski Artur , Moniuszko Anna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Jakubowska Ewa , Kretowski Adam

Background: Ghrelin and obestatin are two gastrointestinal peptides obtained by post-translational processing of a common precursor, preproghrelin. mRNA expression for preproghrelin was found in autoimmune thyroid diseases (AITDs) in previous studies. There are papers, where a role of preproghrelin polymorphism on various immunological diseases was determined, but nothing is known about its influence on the AITDs.Objective and hypotheses: The aim of our ...

Altered DNA Methylation in Peripheral T-cells from Patients with Congenital Adrenal Hyperplasia

Karlsson Leif , Barbaro Michela , Ewing Ewoud , Gomez-Cabrero David , Lajic Svetlana

Background: Patients with Congenital Adrenal Hyperplasia (CAH) are at risk of several co-morbidities, such as impaired cognitive functions, short stature and adverse effects on metabolism. The causes of these effects are suboptimal glucocorticoid replacement therapy, adrenal crises and prenatal glucocorticoid exposure. However, there are no data available to this day how these factors are affecting epigenomic programs.Objective and hypot...

Kallmann Syndrome Due to a Homozygous Missense c.217C>T (p.R73C) Mutation Detected in the Exon-2 of the PROK2 Gene

Ozturk Mehmet Nuri , Demirbilek Huseyin , Kotan Leman Damla , Baysal Birsen , Ocal Murat , Topaloglu Ali Kemal

Background: Kallmann syndrome (KS), the prototype of anosmic idiopathic hypogonadotropic hypogonadism (IHH), is charecterized with HH acompanied by anosmia, absence or hypoplasia of olfactory bulbus due to defective morphogenesis. Mutations in 10 genes have been reported to cause KS while can clarify the underlying molecular defect in about 30–50% of IHH/KS cases. Beside, PROK2 gene mutations are extremely rare cause of KS. Herein, we present KS due to a homozygo...

Background and Aim: Recombinant growth hormone (GH) is reimbursed for the treatment of short stature (<-2.5 Z-score) in children born small for gestational age (SGA) without postnatal growth, aged ≥ 4 years with a height Z-score >1 below mid-parental height (MPH). We wanted to determine the current GH prescribing practices by pediatric endocrinologists (PE) for SGA related short stature and document the percentages of treated children at risk for...

RXFP2: validating its role in autosomal recessive bilateral cryptorchidism and a novel association with male infertility

Background/Aims: Cryptorchidism or undescended testis is a prevalent congenital urogenital condition affecting male newborns with an incidence rate ranging from 1.0 to 4.6%. Mouse models have implicated INSL3 and its receptor RXFP2 (formerly known as GREAT or LGR8) in the development of the condition. RXFP2 acts as a G protein-coupled receptor that triggers the generation of cAMP by binding INSL3. But despite the established role in testicular descent, so far ...

Preferential Paternal Transmission of the T Allele for the rs1802710 Polymorphism In Dlk1 Gene as a Pre- and Postnatal Growth Regulator

Prats-Puig Anna , Carreras-Badosa Gemma , Xargay-Torrent Silvia , Petry Clive J , Redondo-Bautista Lara , de Zegher Francis , Bassols Judit , Ibanez Lourdes , Dunger David B , Lopez-Bermejo Abel

Background: DLK1 or PREF1 is an imprinted gene highly expressed from the paternal allele in embryonic tissues and placenta. It has been recently implicated in adipose tissue expansion and diabetes development. The human rs1802710 polymorphism (SNP) in DLK1 gene has been associated with early-onset extreme obesity but its role determining growth is unknown.Objective and hypotheses: To study the preferential paternal transmission...
