A new type of inhalation aerosol, characterized by particles of small mass density and large size, permitted the highly efficient delivery of inhaled therapeutics into the systemic circulation. Particles with mass densities less than 0.4 gram per cubic centimeter and mean diameters exceeding 5 micrometers were inspired deep into the lungs and escaped the(More)
We describe a rapid and general technology working entirely in vitro to evolve either the affinity or the stability of ligand-binding proteins, depending on the chosen selection pressure. Tailored in vitro selection strategies based on ribosome display were combined with in vitro diversification by DNA shuffling to evolve either the off-rate or(More)
OBJECT Interleukin-12 (IL- 12) has potential for the treatment of tumors because it can stimulate an antitumor immune response and possesses antiangiogenic properties. In the study reported here, the authors investigated the therapeutic role of locally delivered IL-12 in a malignant brain tumor model. METHODS After genetically engineering 9L gliosarcoma(More)
Combinatorial approaches in biology require appropriate screening methods for very large libraries. The library size, however, is almost always limited by the initial transformation steps following its assembly and ligation, as other all screening methods use cells or phages and viruses derived from them. Ribosome display is the first method for screening(More)
Human brain encompasses six tau isoforms, containing either three (3R) or four (4R) repeat domains, all of which participate in the pathogenesis of human tauopathies. To investigate the role of tau protein in the disease, transgenic rat models have been created. However, unlike humans, it has been suggested that rat brain expresses only three 4R tau(More)
Interaction of a single-chain antibody fragment (scFv) with its cognate antigen while still attached to the ribosome was studied by fluorescence correlation spectroscopy (FCS). In experiments with purified scFv, FCS was capable of resolving the difference in diffusion time between free and antibody-bound labelled antigen. Ribosome-displayed antibody(More)
Accumulation of misfolded forms of microtubule associated, neuronal protein tau causes neurofibrillary degeneration typical of Alzheimer's disease and other tauopathies. This process is accompanied by elevated cellular stress and concomitant deregulation of heat-shock proteins. We used a transgenic rat model of tauopathy to study involvement of heat shock(More)
A plasmid pUChEF-2 containing the coding sequence as well as the complete 3'-untranslated region (3'UTR) of human EF-2 mRNA was constructed. The plasmid construct was assembled from a cDNA insert of pHGR81 (Rapp et al., (1988) Biol. Chem. Hoppe-Seyler 369, 247-250) comprising the C-terminal portion of the coding region and the 3'UTR, as well as a polymer(More)
