Background Mammalian cells are a widely used expression platform for the production of recombinant therapeutic proteins or viral particle-based vaccines since they typically perform appropriate protein post-translational modifications and authentic viral particle assembly. Of the available mammalian cells, HEK 293 is one of the most industrially relevant(More)
HIV-1 virus-like particles (VLPs) have great potential as new-generation vaccines. The novel CAP-T cell line is used for the first time to produce Gag-GFP HIV-1 VLPs by means of polyethylenimine (PEI)-mediated transient transfection. CAP-T cells are adapted to grow to high cell densities in serum-free medium, and are able to express complex recombinant(More)
The manufacturing of biopharmaceuticals in mammalian cells typically relies on the use of stable producer cell lines. However, in recent years, transient gene expression has emerged as a suitable technology for rapid production of biopharmaceuticals. Transient gene expression is particularly well suited for early developmental phases, where several(More)
Accurate information on the distribution, demography, and conservation status of endangered populations in threatened habitats are essential to provide the basis for conservation actions and management plans. Neglect of western Ecuador by biologists has resulted in a paucity of information of primate populations in the region. Capuchins (Cebus spp.) and(More)
Background Upon expression, the Gag polyprotein of HIV-1 spontaneously assembles giving rise to enveloped virus-like particles (VLPs). These particulate immunogens offer great promise as HIV-1 vaccines. In order to develop robust VLP manufacturing processes, the availability of simple, fast and reliable quantitation tools is crucial. Traditionally,(More)
We have previously observed that intracerebroventricular infusion of a 5-HT2A receptor antisense oligonucleotide for 8 days results in an increase in cortical 5-HT2A receptor sites and an increase in central 5-HT2A receptor function as measured by quantitation of 5-HT2A receptor-mediated headshake behavior (28). Because lesioning serotonergic neurons or(More)
P11 cells were transfected with DNA for the human 5-hydroxytryptamine1A (5-HT1A) receptor. These cells stably expressed the 5-HT1A receptor coupled to the inhibition of adenylyl cyclase, and not to the stimulation of phosphoinositide hydrolysis. Homologous and heterologous regulation of the 5-HT1A receptor was studied in this cell system. Pretreatment of(More)
