A PCR assay was developed by using degenerate primers that allow amplification of a 414-bp fragment of DNA from the rickettsia-like organisms Rochalimaea henselae and R. quintana. Internal oligonucleotides were used as hybridization probes, permitting rapid differentiation of these two Rochalimaea species. DNAs from 12 different isolates of R. henselae were(More)
Because the choroid plexus (CP) is uniquely suited to control the composition of cerebrospinal fluid (CSF), there may be therapeutic benefits to increasing the levels of biologically active proteins in CSF to modulate central nervous system (CNS) functions. To this end, we sought to identify peptides capable of ligand-mediated targeting to CP epithelial(More)
Epstein-Barr virus (EBV) nuclear antigen 3C (EBNA3C) is one of the essential latent antigens for primary B-cell transformation. Previous studies established that EBNA3C facilitates degradation of several vital cell cycle regulators, including the retinoblastoma (pRb) and p27(KIP) proteins, by recruitment of the SCF(Skp2) E3 ubiquitin ligase complex. EBNA3C(More)
Adenovirus (Ad) is an efficient and safe vector for CNS gene delivery since it infects non-replicating neurons and does not cause insertional mutagenesis of host cell genomes. However, the promiscuous Ad CAR receptor targets cells non-specifically and activates a host immune response. Using Ad5 containing an expression cassette encoding the gene for green(More)
Asunaprevir (ASV), an investigational, highly protein-bound inhibitor of hepatitis C virus NS3 protease, shows considerable hepatic compartmentalization in animal models. Preclinical data showed ASV inhibition of human OATP1B1 (IC50 = 0.3 μM), OATP2B1 (0.27 μM), and, to a lesser extent OATP1B3 (3.0 μM), confirmed by modest (<2-fold) clinical elevations in(More)
Because the choroid plexus normally controls the production and composition of cerebrospinal fluid and, as such, its many functions of the central nervous system, we investigated whether ligand-mediated targeting could deliver genes to its secretory epithelium. We show here that when bacteriophages are targeted with epidermal growth factor, they acquire the(More)
Polymerase chain reaction primers specific for Ehrlichia chaffeensis were used to amplify DNA from extracts of pooled ticks. Amplification was performed on extracts from 140 pools (1,579 total ticks) consisting of three tick genera collected from five states. The characteristic 389-basepair product was observed after amplification of extracts from seven(More)
The duplication of chromosome 3q is a rare disorder with varying chromosomal breakpoints and consequently symptoms. Even rarer is the unbalanced outcome from a parental inv(3) resulting in duplicated 3q and a deletion of 3p. Molecular karyotyping should aid in precisely determining the length and breakpoints of the 3q+/3p- so as to better understand a(More)
Baculovirus recombinants that express the Rickettsia rickettsii rOmpA protein were constructed. Monoclonal antibodies (mAbs) against the rOmpA protein reacted with recombinant-infected Spodoptera frugiperda (Sf9) cells in indirect immunofluorescence assays. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting of infected Sf9 cell(More)
