Cloning techniques are fundamental to molecular biology. Classically, recombinant plasmid and/or phage vectors are prepared in vitro, the transformation step only serving for amplification purposes. A different approach would exploit the natural intracellular enzymatic machinery to produce recombinant DNA molecules. Such techniques are well-known to(More)
The dopamine transporter (DAT) is a crucial regulator of dopaminergic neurotransmission, controlling the length and brevity of dopaminergic signaling. DAT is also the primary target of psychostimulant drugs such as cocaine and amphetamines. Conversely, methylphenidate and amphetamine are both used clinically in the treatment of attention-deficit(More)
The dopamine transporter (DAT) is responsible for sequestration of extracellular dopamine (DA). The psychostimulant amphetamine (AMPH) is a DAT substrate, which is actively transported into the nerve terminal, eliciting vesicular depletion and reversal of DA transport via DAT. Here, we investigate the role of the DAT C terminus in AMPH-evoked DA efflux(More)
We have examined the requirement for the transmembrane hydrophobic anchor sequence of the influenza hemagglutinin (HA) in the formation of the antigenic moiety on the surface of target cells recognized by class I MHC-restricted murine CTL. For this analysis we have used a line of CV-1 monkey epithelial cells that express the transfected murine H-2Kd gene(More)
Anti-idiotypic antibodies (Ab2) were raised in allotype-matched rabbits against anti-carbohydrate or anti-tobacco mosaic virus antibodies (Ab1). Several Ab2 were purified and injected into a third series of rabbits III which synthesized antiantiidiotypic antibodies (Ab3). Antigen was then given for the first time in those rabbits who had synthesized Ab3.(More)
Background Neuronal functions, such as excitability or endo-and exo-cytosis, require phosphatidylinositol-4,5-bisphosphate (PIP 2) since ion channels and other proteins involved in these processes are regulated by PIP 2. Monoamine transporters control neurotransmission by removing monoa-mines from the extracellular space. They also display channel(More)
