Auwerx, Joeri, Stevens, Miguel, Van Rompay, An R., Bird, Louise E., Ren, Jingshan, De Clercq, Erik, ...

The phenylmethylthiazolylthiourea (PETT) derivative MSK-076 shows, besides high potency against human immunodeficiency virus type 1 (HIV-1), marked activity against HIV-2 (50% effective...

Interleukin-8-Derived Peptide Has Antibacterial Activity

Björstad, Åse, Fu, Huamei, Karlsson, Anna, Dahlgren, Claes, Bylund, Johan

Chemokines are inflammatory mediators with effects on diverse processes associated with the immune response. Some of the proteins belonging to the CXC chemokine subfamily, one of four groups in the...

Changes in Activation States of Murine Polymorphonuclear Leukocytes (PMN) during Inflammation: a Comparison of Bone Marrow and Peritoneal Exudate PMN

Itou, Takuya, Collins, L. Vincent, Thorén, Fredrik B., Dahlgren, Claes, Karlsson, Anna

To study different activation states in polymorphonuclear leukocytes (PMN) in mice, we compared the function of murine PMN obtained from the bone marrow (BMPMN) with those of PMN obtained by...

Neutrophil Secretion Induced by an Intracellular Ca2+ Rise and Followed by Whole-Cell Patch-Clamp Recordings Occurs Without any Selective Mobilization of Different Granule Populations

Granfeldt, Daniel, Harbecke, Olle, Björstad, Åse, Karlsson, Anna, Dahlgren, Claes

We have investigated calcium-induced secretion in human neutrophils, using a whole-cell patch-clamp technique. Mobilization of subcellular granules to the cell membrane was followed as the change in...

The mechanism for activation of the neutrophil NADPH-oxidase by the peptides formyl-Met-Leu-Phe and Trp-Lys-Tyr-Met-Val-Met differs from that for interleukin-8

Fu, Huamei, Bylund, Johan, Karlsson, Anna, Pellmé, Sara, Dahlgren, Claes

Neutrophil chemotaxis has been shown to be regulated by two different signalling pathways that allow strong chemoattractants, such as bacterial-derived formylated peptides, to dominate over...

Ability of Monocyte-Derived Dendritic Cells To Secrete Oxygen Radicals in Response to Formyl Peptide Receptor Family Agonists Compared to That of Myeloid and Plasmacytoid Dendritic Cells▿

Karlsson, Anna, Nygren, Erik, Karlsson, Jennie, Nordström, Inger, Dahlgren, Claes, Eriksson, Kristina

We show that human monocyte-derived dendritic cells (DC) differ considerably from freshly isolated blood-derived myeloid and plasmacytoid DC in their abilities to produce reactive oxygen species in...

Nucleotide affinity for a stable phosphorylated intermediate of nucleoside diphosphate kinase

Schneider, Benoit, Norda, Ameli, Karlsson, Anna, Veron, Michel, Deville-Bonne, Dominique

Nucleoside diphosphate (NDP) kinase is transiently phosphorylated on a histidine of the active site during the catalytic cycle. In the presence of a nucleotide acceptor, the phosphohistidine bond is...

Genetic Profiling Differentiates Second Primary Tumors from Metastases in Adult Metachronous Soft Tissue Sarcoma

Fernebro, Josefin, Carneiro, Ana, Rydholm, Anders, Domanski, Henryk A., Karlsson, Anna, Borg, Åke, ...

Purpose. Patients with soft tissue sarcomas (STS) are at increased risk of second primary malignancies, including a second STS, but distinction between metastases and a second primary STS is...

Leaching of Flame Retardants from products deposited in Landfills

Hörsing, Maritha, Karlsson, Anna, Jonsson, Susanne, Svensson, Bo H

  Materials in many products in daily use are amended with chemicals to give them desired properties, e.g. flame retardants (FRs) used to reduce the risks of products catching fire. However,...
