Studies with molecular and immunological techniques identified and mapped the transcript encoding glycoprotein D (gD) of equine herpesvirus 1 KyA, as well as two continuous gD antigenic determinants. Three mRNA species of 5.5, 3.8, and 1.7 kb overlap the gD open reading frame and are transcribed from the DNA strand encoding gD. Northern (RNA) blot hybridization with both DNA clones and riboprob...

During virus entry, herpes simplex virus (HSV) glycoprotein D (gD) binds to one of several human cellular receptors. One of these, herpesvirus entry mediator A (HveA), is a member of the tumor necrosis factor receptor (TNFR) superfamily, and its ectodomain contains four characteristic cysteine-rich pseudorepeat (CRP) elements. We previously showed that gD binds the ectodomain of HveA expressed ...

Background: Graves’ disease (GD), a highly rampant autoimmune disorder of the thyroid gland, is responsible for 60-80% of the clinical cases of hyperthyroidism. Over the past decades, genetic association studies have identified several GD susceptibility loci in CTLA-4, TSHR and major histocompatibility complex regions. The information on the association between the human leukocyte antigens (HLA...

Vitamin D deficiency (VDD) is widespread in the general population. Iodinated (IC) or gadolinium-based contrast media (Gd) may decrease renal function in high-risk patients. This study tested the hypothesis that VDD is a predisposing factor for IC- or Gd-induced nephrotoxicity. To this end, male Wistar rats were fed standard (SD) or vitamin D-free diet for 30 days. IC (diatrizoate), Gd (gadoter...

32 As the receptor-binding protein of HSV, gD plays an essential role in virus entry. In its 33 native state, the last 56 amino acids of the ectodomain C-terminus (C-term) occlude 34 binding to its receptors, HVEM and nectin-1. Although it is clear that movement of the C35 term must occur to permit receptor binding, we believe that this conformational change is 36 also a key event for triggerin...

Glycoprotein D (gD-2) is the entry receptor of herpes simplex virus 2 (HSV-2), and is the immunogen in the pharmaceutical industry's lead HSV-2 vaccine candidate. Efforts to prevent genital herpes using gD-2 subunit vaccines have been ongoing for 20 years at a cost in excess of $100 million. To date, gD-2 vaccines have yielded equivocal protection in clinical trials. Therefore, using a small an...

The molecular characterization of the epitope repertoire on herpes simplex virus (HSV) antigens would greatly expand our knowledge of HSV immunity and improve immune interventions against herpesvirus infections. HSV glycoprotein D (gD) is an immunodominant viral coat protein and is considered an excellent vaccine candidate antigen. By using the TEPITOPE prediction algorithm, we have identified ...

Gaucher disease (GD), the most common lysosomal storage disease, is caused by mutations in GBA1 encoding of β-glucocerebrosidase (GCase). Recently it was reported that progranulin (PGRN) insufficiency and deficiency associated with GD in human and mice, respectively. However the underlying mechanisms remain unknown. Here we report that PGRN binds directly to GCase and its deficiency results in ...

PD-1 maintains tolerance and inhibits autoimmune responses. Graves' disease (GD) is one of the most frequent autoimmune diseases of unclear etiology. The aim of this study was to evaluate the percentage and absolute counts of PD-1 positive T and B cells in newly diagnosed, untreated patients with hyperthyroidism due to GD. The study group included 30 patients and the control group comprised of ...

The pulse DEER (Double Electron-Electron Resonance) technique is frequently applied for measuring nanometer distances between specific sites in biological macromolecules. In this work we extend the applicability of this method to high field distance measurements in a protein assembly with mixed spin labels, i.e. a nitroxide spin label and a Gd(3+) tag. We demonstrate the possibility of spectros...
