Glycoprotein D (gD) of herpes simplex virus (HSV) binds to a host cell surface receptor, which is required to trigger membrane fusion for virion entry into the host cell. gD has become a validated anti-HSV target for therapeutic antibody development. The highly inhibitory human monoclonal antibody E317 (mAb E317) was previously raised against HSV gD for viral neutralization. To understand the s...

BACKGROUND AND OBJECTIVES There is increasing evidence that galactose-deficient IgA1 (Gd-IgA1) and Gd-IgA1-containing immune complexes are important for the pathogenesis of IgA nephropathy (IgAN). In the present study, we assessed a novel noninvasive multi-biomarker approach in the diagnostic test for IgAN. MATERIALS AND METHODS We compared serum levels of IgA, IgG, Gd-IgA1, Gd-IgA1-specific ...

Initial contact between herpesviruses and host cells is mediated by virion envelope glycoproteins which bind to cellular receptors. In several alphaherpesviruses, the nonessential glycoprotein gC has been found to interact with cell surface proteoglycans, whereas the essential glycoprotein gD is involved in stable secondary attachment. In addition, gD is necessary for penetration, which involve...

Liver tumors are common and imaging methods, particularly magnetic resonance imaging (MRI), play an important role in their non-invasive diagnosis. Previous studies have shown that detection of liver tumors can be improved by injection of two different MR contrast agents. Here, we developed a new contrast agent, Gd-manganese-doped magnetism-engineered iron oxide (Gd-MnMEIO), with enhancement ef...

Four glycoproteins (gD, gB, gH, and gL) are essential for herpes simplex virus (HSV) entry into cells. An early step of fusion requires gD to bind one of several receptors, such as nectin-1 or herpesvirus entry mediator (HVEM). We hypothesize that a conformational change in gD occurs upon receptor binding that triggers the other glycoproteins to mediate fusion. Comparison of the crystal structu...

Existing data suggest a negative correlation between maternal sleep deprivation and male offspring reproductive capability. However, there is dearth of information on the critical period of development during which reproductive organs may be programmed. Thirty pregnant rats were divided into six groups based on the Gestation Days (GD) during which they were sleep deprived as follows: GD 17 cont...

PURPOSE The feasibility of measuring blood-brain barrier permeability was studied in a 36B-10 brain glioma model in rats. MATERIALS AND METHODS In stage I of our study, sequential MR images of glioma-implanted rats were obtained following intravenous administration of three contrast agents of different molecular sizes--Gd-DTPA, polylysine-(Gd-DTPA), and albumin-(Gd-DTPA). In a second set of e...

We evaluated R1 curves, CNR and scar visualization and quantification in a dog model of myocardial infarction by CMR, using three different contrast agents: Gadopentate dimeglumine (Gd-DTPA, Magnevist), Gadobenate dimeglumine (Gd-BOPTA, MultiHance), and Gadofosveset (Ablavar). Gd-DTPA showed better characteristics for myocardial scar visualization and quantification. Gadofosveset demonstrated l...

A kind of Gd@C82 salt, Gd@C82/TBPA, was prepared through chemical oxidation. The Gd@C82/TBPA salt was characterized as being paramagnetic with an effective magnetic moment of 9.68μB. The Gd@C82/TBPA salt dissolves in many organic solvents and its high solubility will make it more applicable for use as a magnetic material.

Human herpesvirus entry mediator C (HveC) is an alphaherpesvirus receptor which binds to virion glycoprotein D (gD). We identified porcine HveC and studied its interaction with pseudorabies virus (PrV) and herpes simplex virus type 1 (HSV-1) gD. Porcine and human HveC have 96% amino acid identity and HveC from African green monkey, mouse, hamster, and cow are similarly conserved. Porcine HveC m...
