Circulating microRNAs are protected from degradation by their association with either vesicles or components of the RNAi machinery. Although increasing evidence indicates that cell-free microRNAs are transported in body fluids by different types of vesicles, current research mainly focuses on the characterization of exosome-associated microRNAs. However, as isolation and characterization of exo...

Rifampin reversibly inhibits the intracellular replication of a VSV mutant, whereas a revertant variant selected from this viral population, as well as the wild strain, are not affected by this drug. Rifampin inhibits transcriptase activity of the sensitive mutant only and, consequently, total viral RNA synthesis decreases significantly in the cells.

Structures of L proteins from La Crosse orthobunyavirus and vesicular stomatitis virus reveal insights into RNA synthesis and distinctive mRNA capping mechanisms of segmented and non-segmented negative-sense single-strand RNA viruses.

Recent studies demonstrated that vesicular dopamine (DA) uptake can be rapidly altered in synaptic vesicles purified from the striata of stimulant-treated rats. Specifically, a single administration of the plasmalemmal DA transporter inhibitor, cocaine, or the DA D(2) agonist, quinpirole, increases vesicular DA uptake in vesicles purified from the striata of treated rats. These effects of cocai...

It has been suggested that dopamine derived from exogenous levodopa may not follow vesicular dynamics in Parkinson's disease (PD). Using a novel PET method based on the sensitivity of [(11)C]-dihydrotetrabenazine (DTBZ) binding to changes in vesicular dopamine levels, we show here that striatal [(11)C]-DTBZ binding decreases after levodopa administration in advanced PD, likely reflecting an inc...

There are three families of vesicular neurotransmitter transporters. The vesicular amine transporters (VATs) are members of the toxin-extruding protontranslocating antiporter family (TEXANs) (1). The vesicular inhibitory amino acid transporter (VIAAT/ VGAT) is a member of a second family with limited homology to plant amino acid permeases (2, 3). A vesicular transporter for the excitatory amino...
