“Cell-penetrating peptides (CPPs) have been previously shown to be powerful transport vector tools for the intracellular delivery of a large variety of cargoes through the cell membrane. Intracellular delivery of plasmid DNA (pDNA), oligonucleotides, small interfering RNAs (siRNAs), proteins and peptides, contrast agents, drugs, as well as various nanoparticulate Emricasan nmr pharmaceutical carriers (e.g., liposomes, micelles) has been demonstrated both in vitro and
in vivo. This review focuses on the peptide-based strategy for intracellular delivery of CPP-modified nanocarriers to deliver small molecule drugs or DNA. In addition, we discuss the rationales for the design of ‘smart’ pharmaceutical nanocarriers in which the cell-penetrating properties are hidden until triggered by exposure to appropriate environmental conditions (e.g., a particular pH, temperature, or enzyme level), applied local microwave, ultrasound, or radiofrequency radiation.”
“The blood-brain barrier (BBB) is a vascular endothelial interface that separates the brain interior from the bloodstream. Membrane proteins resident at the BBB play important functional and regulatory roles. The current study describes the development and successful implementation of a multiplex expression cloning (MEC) method to allow facile
identification of BBB membrane proteins. The overriding goal of the MEC approach was to mine a BBB cDNA library and selectively isolate membrane protein-encoding Anlotinib cDNAs. This selection process was achieved via fluorescence-activated cell sorting (FACS) of cDNA-expressing mammalian host cells for those cells that were immunolabeled with a BBB membrane protein-specific polyclonal antiserum (BMSPA). After optimization of the host cell expression system, four selection rounds allowed the isolation of a panel of 15 unique cDNAs that encoded BBB membrane proteins. The identified proteins display significant diversity in structure, function and in vivo expression new levels. The MEC approach thus proved effective for conducting moderate throughput membrane proteome analyses of the BBB while limiting any biases caused by membrane protein insolubility or low in
vivo expression levels that can complicate other proteomic approaches.”
“BACKGROUND
For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy.
METHODS
In this double-blind, randomized, placebo-controlled study, 55 children, 5 to 11 years of age, with egg allergy received oral immunotherapy (40 children) or placebo (15). Initial dose-escalation, build-up, and maintenance phases were followed by an oral food challenge with egg-white powder at 10 months and at 22 months. Children who successfully passed the challenge at 22 months discontinued oral immunotherapy and avoided all egg consumption for 4 to 6 weeks.
