Membrane proteins stick around
You wouldn't call it a long-term relationship, but the interaction between proteins and certain membrane lipids is not just a one-millisecond stand. As Hammond et al. discovered, the proteins remain attached to the lipids longer than researchers expected. The fi ndings explain how these lipids localize their effects. By temporarily hooking up with various proteins, inositol lipids in the plasma...
متن کاملForcing cells to stick around
eukocytes have a better chance of sticking to neighboring cells with the right ligands if they rotate on their way by, based on results from Dwir et al. (page 649). Flowing leukocytes are captured via L-selectin interactions with carbohydrate ligands on vessel walls and subsets of other leukocytes. L-selectin is an unusual adhesive molecule—shear stress improves its adherance to ligands, wherea...
متن کاملWhat does it take to stick around? Molecular insights into biofilm formation by uropathogenic Escherichia coli.
Existence in the biofilm state lends bacteria the opportunity to enjoy, at least for a finite amount of time, the benefits of a multicellular entity. The order of events leading to biofilm formation and disassembly has been the topic of interest for numerous studies, aiming to identify factors and mechanisms that underlie this dynamic developmental process. Of particular import is research leve...
متن کاملDont Breathe and Drive? Pollutants Lurk inside Vehicles
The ability of human immunodeficiency virus type 1 (HIV-1) to develop high levels of genetic diversity, and thereby acquire mutations to escape immune pressures, contributes to the difficulties in producing a vaccine. Possibly no single HIV-1 sequence can induce sufficiently broad immunity to protect against a wide variety of infectious strains, or block mutational escape pathways available to ...
متن کاملSome Have a Talent for Bargaining and Some Dont
In Bargaining Theory players di¤er from one another in either their valuation for the negotiated object and/or their time preferences. We suggest a model that incorporates "bargaining ability" as another source for heterogeneity across players. This bargaining ability for the buyer determines how many o¤ers he will be able to turn down before he walks away. For the seller this ability determine...
