Here, we show that treatment with a sialidase significantly improved the capacity of both immature and mature MDDCs to phagocytose Escherichia coli. Namely, neuraminidase-treated DCs show increased gene transcription of proinflammatory and Th1-promoting cytokines and induce greater proliferative responses of T lymphocytes. Dendritic cells (DCs) play an essential role in immunity against bacteria by phagocytosis and by eliciting adaptive immune responses. Previously, we demonstrated that human m...

To confirm correct sequences in plasmids constructed, the plasmids can be analyzed by standard techniques such as by restriction endonuclease digestion, and/or sequencing according to known methods. Yeast Integrating plasmids (e.g., YIp5) and Yeast Replicating plasmids (the YRp series plasmids) and pGPD-2. Media can be rich media, e.g., Luria broth or terrific broth, or synthetic or semi-synthetic medium, e.g., M9 medium. A "culture medium" refers to any liquid, semi-solid or solid media that c...

Homonuclear 2D 1H,1H COSY and 1H,1H TOCSY experiments showed connectivity of this proton to one and two other protons, respectively (Fig. S2). Signal 2, at 2.73 ppm, corresponds then to a proton neighboring a carbonyl on one side and at least two other protons on the other side with chemical shifts in the 3-4 ppm region. Analysis of the 3-4 ppm spectral region, where standard sugar-ring C-H signals typically show, suggests that the intermediate chemical shifts are closer to Neu5Ac than to 2,7-a...

Treatment of isolated-perfused lungs with neuraminidase from Vibrio cholerae leads to pulmonary edema. A third key observation in our study is the pattern of alveolar edema observed when isolated-perfused lungs were treated with neuraminidase from Vibrio cholerae. A second key observation in our study is that terminally linked sialic acids are important contributors to endothelial barrier integrity. A principal observation in our study is that there is heterogeneity in sialic acid expression be...

Match up the requirements of your chemical technicians with listings on our market, and stock up to verify all of your reactions are covered. Sometimes chemical processes are only as robust because the hyperlinks in between, and you cannot reach the specified end level with out discovering the suitable mixture of catalysts to make reactions run smoothly. They represent mid-factors in industrial reactions in multi-step processes, and in some circumstances can speed up chemical production by avoi...

Background was washed out with deionized water and gel was scanned with the default instrument settings for analysis (Lexmark CX727 scanner). Inhibition of glycolipid synthesis was carried out as described previously (36) with some modifications. Resialylation was carried out with 50 mU/ml sialyltransferase in α-MEM for 2 h at 37°C.

In some experiments the bacterial surface was desialylated with 13· In the earlier set of experiments that utilized neuraminidase, we noted that, following neuraminidase treatment, there were typically fewer cells in the dish, indicating that cells had lost cell-cell and/or cell-matrix adhesions. Sialic acid quantitation was carried out using the Sialic Acid (NANA) Assay kit from Biovision (Mountain View, CA) following the manufacturer's protocol. Briefly, a 15-cm dish of HEK 293 cells (ca. 2 ×...

The resulting weight gain during the last 2 min of raising the venous pressure was divided by the concomitant increment of capillary pressure, and values were normalized to predicted lung weight. The amounts of activated Rac1 or Cdc42 (arbitrary units) are based on the optical density values obtained after subtracting negative control values. A "recombinant expression cassette" or simply an "expression cassette" is a nucleic acid construct, generated recombinantly or synthetically, with nucleic...
