1. In view of previously demonstrated modulatory effects of PLG on the sensitivity of central dopamine receptors, we developed a radioligand binding assay to identify specific binding sites of PLG in rat and normal human brain. 2. 3H-PLG binds specifically to rat striatum exhibiting high affinity (KD = 4.69 +/- 0.50 nM) saturability (Bmax = 9.20 +/- 0.30(More)
Helicobacter pylori establishes persistent infection of gastric mucosa with diverse clinical outcomes. The innate immune molecule surfactant protein D (SP-D) binds selectively to microorganisms, inducing aggregation and phagocytosis. In this study, we demonstrated the expression of SP-D in gastric mucosa by reverse transcription-PCR and immunohistochemical(More)
Helicobacter pylori is a common and persistent human pathogen of the gastric mucosa. Surfactant protein D (SP-D), a component of innate immunity, is expressed in the human gastric mucosa and is capable of aggregating H. pylori. Wide variation in the SP-D binding affinity to H. pylori has been observed in clinical isolates and laboratory-adapted strains. The(More)
Some Campylobacter jejuni strains which exhibit mimicry of gangliosides in their lipooligosaccharides (LOSs) are associated with development of Guillain-Barré syndrome, which complicates the selection of a suitable C. jejuni strain in a live-attenuated vaccine. C. jejuni 81-176 is the most well characterized strain available, but structurally, LOS of C.(More)
The genome of Helicobacter pylori 26695 has been sequenced and the lipopolysaccharide (LPS) O sidechain of this strain has been shown to express both Lewis x and Lewis y units. To determine the role of HP0159 and HP1416, genes recognized as rfaJ homologs and implicated in LPS synthesis, isogenic mutants of H. pylori 26695 were generated. The LPS of mutant(More)
