Mechanisms of Ganglioside Inhibition of APC

Inhibition of TLR activation and up-regulation of IL-1R-associated kinase-M expression by exogenous gangliosides.

Gangliosides, sialic acid-containing glycosphingolipids present in the outer leaflet of plasma membranes, are produced at high levels by some tumors, are actively shed into the tumor microenvironment, and can be detected in high concentrations in the serum of cancer patients. These tumor-shed molecules are known to be immunosuppressive, although mechanisms remain to be fully elucidated. In this...

Comparison of Immunoblotting and ELISA for Detection of Anti-Ganglioside Antibodies in Children with Guillain-Barre Syndrome

Background: Anti-ganglioside antibody assays are widely used for diagnosis of autoimmune peripheral neuropathies. Objective: This study aimed to determine serum levels of anti-ganglioside antibodies in children with Guillain-Barre syndrome by immunoblotting technique and compare the results with those obtained by ELISA method. Method: In this investigation, 50 children with Guillain-Barre syndr...

Downregulation of IL-12 Production in Healthy Non-Responder Neonates to Recombinant Hepatitis B Vaccine

A proportion of healthy neonates and adults fail to develop a protective antibody response to recombinant hepatitis B (HB) vaccine. Unresponsiveness to vaccination could be attributed to defect in a number of immunological regulatory mechanisms. In this study, IL-12 was quantitated in culture supernatant following in vitro stimulation of peripheral blood mononuclear cells isolated from a group ...

بررسی الگوی متیلاسیون و بیان ژن APC به دنبال تمایز سلول‌های بنیادی مزانشیمی مشتق از مغز استخوان به رده استئوبلاستی

Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression ...
