Evidence that the Receptor for Soluble CD14:LPS Complexes may not be the Putative Signal-Transducing Molecule Associated with Membrane-Bound CD14

Membrane-bound CD14 acts as a receptor for lipopolysaccharide (LPS) on monocytes/macrophages and neutrophils. Studies have suggested that the activation of monocytes/macrophages by the binding of LPS to membrane-bound CD14 may require the association of a signal-transducing molecule with membrane-bound CD14. The observation that non-CD14 expressing cells, such as endothelial cells, can nevertheless be activated by a complex of LPS and a soluble form of CD14 (sCD14) suggests that the receptor for this complex may be identical to the signal transducing molecule associated with membrane-bound CD14. The studies described show that two CD14-specific MoAb are able to block the LPS-induced activation of endothelial cells but do not affect the response of monocytes to LPS. This suggests that the interaction of the sCD14:LPS complex with endothelial cells is distinct from the interaction of membrane-bound CD14 with its putative signal-transducing molecule.     

High-resolution loading tests in the study of genetic heterogeneity in gangliosidosis fibroblasts

Summary GM₁- and GM₂-gangliosides were isolated from brain and radio-labelled. The labelled moieties were localized by hydrolysis with lysosomal enzymes, followed by thin-layer chromatography of the products. High-resolution loading tests with labelled gangliosides were developed and found to differentiate infantile and juvenile forms of GM₁- and GM₂-gangliosidoses as well as the identification of B, O and AB types of GM₂-gangliosidosis.     

小儿糖尿病血胰岛细胞抗体与胰岛素自身抗体

报道并分析20例小儿糖尿病患儿的临床资料及血胰岛细胞抗体(ICA)及胰岛素自身抗体(IAA)的测定资料。在20例患儿中,临床表现多不典型。在酮症酸中毒的治疗中小剂量胰岛素疗法方法简便,安全可靠,并发症少。本组患儿ICA阳性率55%,IAA阳性率30%,经卡方检验均显著高于对照组,推测病毒感染引起自身免疫反应,产生ICA及IAA而致本病发生。     

Reversal of diabetes in BB rats by transplantation of encapsulated pancreatic islets

Prolonged survival of pancreatic islet allografts implanted in diabetic BB rats was achieved by encapsulation of individual islets in a protective biocompatible alginate-polylysine-alginate membrane without immunosuppression. Intraperitoneal transplantation of the encapsulated islets reversed the diabetic state of the recipients within 3 days and maintained normoglycemia for 190 days. Normal body weight and urine volume were maintained during this period, and no cataracts were detected in the transplant recipients. In contrast, control rats receiving transplants of unencapsulated islets experienced normoglycemia for less than 2 wk. These results demonstrated that microencapsulation can protect allografted islets from both graft rejection and autoimmune destruction without immunosuppression in an animal model that mimics human insulin-dependent diabetes.
