1. Determinação das propriedades fotofísicas da pseudoisocianina no microdomínio hidrotrópico e de alginato e em outros meios / Determination of photophysical properties of the pseudoisocyanine in the hydrotropic medium and hydrophobic microdomains in alginate
O meio hidrotrópico tem sido intensamente explorado pela indústria a fim de melhorar a solubilização de substâncias pouco solúveis em água. Os hidrótropos são compostos anfifílicos, como os surfactantes, mas os microdomínios formados não têm estruturas bem organizadas como as micelas. O mecanismo de solubilização hidrotrópica não está compl

2. Asymmetric localization of flotillins/reggies in preassembled platforms confers inherent polarity to hematopoietic cells
Hematopoietic cells have long been defined as round, nonpolar cells that show uniform distribution of cell surface-associated molecules. However, recent analyses of the immunological synapse and the importance of lipid microdomains in signaling have shed new light on the aspect of lymphocyte polarization during the activation processes, but none of the m

3. The Coxsackie B Virus and Adenovirus Receptor Resides in a Distinct Membrane Microdomain
The coxsackie B virus and adenovirus receptor (CAR) is a member of the immunoglobulin superfamily. In addition to activity as a viral receptor, it may play a role in cellular adhesion. We asked what determines the cell membrane microdomain of CAR. We found that CAR is localized to a novel lipid-rich microdomain similar to that of the low-density lipoprotein

4. Carbohydrate-dependent signaling from the phosphatidylglucoside-based microdomain induces granulocytic differentiation of HL60 cells
Glycosphingolipids form glycosphingolipid signaling microdomains. Here, we report an unrecognized type of phosphatidylglucoside (PhGlc)-based lipid microdomain in HL60 cells. Treatment of cells with rGL-7, which preferentially reacts with PhGlc, induced differentiation of HL60 cells. This was manifested by the appearance of nitroblue tetrazolium-positive

5. Characterization of the Cell Wall Microdomain Surrounding Plasmodesmata in Apple Fruit.
In fleshy fruits ripening is generally associated with a loss in tissue firmness resulting from depolymerization of wall components and separation of adjacent cells. In the regions of the wall that contain plasmodesmata, the usual sequences of ripening events, i.e. depolymerization of the middle lamellae and splitting of the walls, are not observed. In the p

6. Rab9 GTPase Regulates Late Endosome Size and Requires Effector Interaction for Its Stability
Rab9 GTPase resides in a late endosome microdomain together with mannose 6-phosphate receptors (MPRs) and the tail-interacting protein of 47 kDa (TIP47). To explore the importance of Rab9 for microdomain establishment, we depleted the protein from cultured cells. Rab9 depletion decreased late endosome size and reduced the numbers of multilamellar and dense-t

7. Expansion of calcium microdomains regulates fast exocytosis at a ribbon synapse
We investigated the Ca2+ signal regulating fast exocytosis at the ribbon synapse of retinal bipolar cells by using total internal reflection fluorescence microscopy to image fluorescent Ca2+ indicators and interference reflection microscopy to monitor exocytosis. Depolarization generated Ca2+ “microdomains” that expanded over the time scale during which

8. Recruitment and interaction dynamics of plant penetration resistance components in a plasma membrane microdomain
Many fungal pathogens must enter plant cells for successful colonization. Barley mildew resistance locus o (Mlo) is required for host cell invasion upon attack by the ascomycete powdery mildew fungus, Blumeria graminis f.sp. hordei, and encodes the founder of a family of heptahelical integral membrane proteins unique to plants. Recessively inherited loss-of-

9. Human Coronavirus 229E Binds to CD13 in Rafts and Enters the Cell through Caveolae
CD13, a receptor for human coronavirus 229E (HCoV-229E), was identified as a major component of the Triton X-100-resistant membrane microdomain in human fibroblasts. The incubation of living fibroblasts with an anti-CD13 antibody on ice gave punctate labeling that was evenly distributed on the cell surface, but raising the temperature to 37°C before fixatio

10. Role of Plasma Membrane Lipid Microdomains in Respiratory Syncytial Virus Filament Formation
The fusion protein (F) of respiratory syncytial virus (RSV) is the envelope glycoprotein responsible for the characteristic cytopathology of syncytium formation. RSV has been shown to bud from selective areas of the plasma membrane as pleomorphic virions, including both filamentous and round particles. With immunofluorescent microscopy, we demonstrated evide

11. A target site for template-based design of measles virus entry inhibitors
Measles virus (MV) constitutes a principal cause of worldwide mortality, accounting for almost 1 million deaths annually. Although a live-attenuated vaccine protects against MV, vaccination efficiency of young infants is low because of interference by maternal antibodies. Parental concerns about vaccination safety further contribute to waning herd immunity i

12. Conductivity and structure of bilinear organic addition compounds
The relationship between crystal structures and metallic conductivities of linear organic materials such as tetrathiafulvalene-tetracyanoquinodimethane is explained in terms of strong lateral elastic interactions between chains. A microdomain model is presented in which at high temperatures there are, in general, two coexisting phases on each stacked molecul
