A continuous-flow microspotter was used to generate planar arrays of stabilized bilayers composed of the polymerizable lipid bis-SorbPC and dopant lipids bearing ligands for proteins. Fluorescence microscopy was used to determine the uniformity of the bilayers and to detect protein binding. After UV-initiated polymerization, poly(lipid) bilayer microarrays were air-stable. Cholera toxin subunit...
Induction of mucosal tolerance by oral administration of protein antigens is a potential therapeutic strategy for preventing and treating type 1 diabetes (T1D); however, the requirement for a large dosage of protein limits clinical applications because of the low efficacy. In this study, we generated a fusion protein CTB-Ins-GAD composed of CTB (cholera toxin B subunit), insulin, and three copi...
Cholera toxin (CT) enters and intoxicates host cells after binding cell surface receptors via its B subunit (CTB). We have recently shown that in addition to the previously described binding partner ganglioside GM1, CTB binds to fucosylated proteins. Using flow cytometric analysis of primary human jejunal epithelial cells and granulocytes, we now show that CTB binding correlates with expression...
Mouse models of influenza play an important role in developing effective human influenza vaccines. We have demonstrated that intranasal immunization with inactivated subvirion (SV) vaccines, in conjunction with a cholera toxin B subunit adjuvant (CTB*), provides more effective cross-protection than parenteral immunization in BALB/c mice. In addition, the minimal effective dose of nasal vaccine ...
INTRODUCTION The syncytiotrophoblast (STB) epithelial covering of the villous tree in the human placenta is a multi-nucleated syncytium that is sustained by continuous incorporation of differentiating cytotrophoblast (CTB) cells. STB nuclei display a variety of morphologies, but are generally more condensed in comparison to CTB nuclei. Here, we consider whether this condensation is a feature of...
Caveolae appear to function in vesicular trafficking of specific molecular cargo into and across vascular endothelial and other cells. They contain the molecular machinery for docking and fusion, similar to other vesicular trafficking systems, yet the mechanisms mediating ligand internalization and targeted intracellular transport by caveolae remain unclear. Using immunoelectron microscopy, we ...
The setting behavior strongly affects the workability and loading capacity of a fresh cemented tailings backfill (CTB). Vicat test is conventional way to measure time cementitious mixture, using standard needle detect penetration resistance. However, this method limited laboratory testing, it difficult carry out in underground closed stopes. In study, two nondestructive methods, ultrasonic puls...
Circulating extracellular vesicles (EVs) such as cholera toxin B chain (CTB)- or annexin V (AV)-binding EVs were previously shown to be rich sources of biomarkers. Here we test if previously identified pre-eclampsia (PE) candidate biomarkers, TIMP-1 in CTB-EVs (CTB-TIMP) and PAI-1 in AV-EVs (AV-PAI) complement plasma PlGF in predicting PE in a low-risk obstetric population. Eight hundred and fo...
Mucosally induced immunological tolerance is an attractive strategy for preventing or treating illnesses resulting from untoward inflammatory immune reactions against self- or non-self-antigens. Oral administration of relevant autoantigens and allergens has been reported to delay or suppress onset of clinical disease in a number of experimental autoimmune and allergic disorders. However, the ap...
Central Tarsal Bone (CTB) Fractures The highest incidence of CTB fractures (96%) occurs in the right leg and some of these can be so devastating that they terminate the patient’s racing career. There are several factors to consider for a thorough understanding of how these fractures occur. During the anti-clockwise racing in the bends, the right hind leg is procuring propulsion but is also coun...
