Integration of a virus membrane protein into the lipid bilayer of target cells as a prerequisite for immune cytolysis

Structural requirements for membrane antigens on target cells to mediate immune cytolysis were studied in a model system with purified membrane proteins from Semliki Forest virus (SFV). These SFV spike proteins were isolated in the form of detergent- and lipid-free protein micelles (29S complexes) or, after reconstitution into lipid vesicles, in the form of virosomes. Both the 29S complexes and the virosomes were found to bind well to murine tumor cells (P815 or Eb). When these cells, however, w...

Cell-Free Synthesis of the Mitochondrial ADP/ATP Carrier Protein of Neurospora crassa

ADP/ATP carrier protein was synthesized in heterologous cell-free systems programmed with Neurospora poly(A)-containing RNA and homologous cell-free systems from Neurospora. The apparent molecular weight of the product obtained in vitro was the same as that of the authentic mitochondrial protein. The primary translation product obtained in reticulocyte lysates starts with formylmethionine when formylated initiator methionyl-tRNA (fMet-tRNAfMet) was present. The product synthesized in vitro was r...

Localized ultraviolet laser microbeam irradiation of early Drosophila embryos: Fate maps based on location and frequency of adult defects

Drosophila embryos were locally irradiated with a 257-nm laser microbeam during blastoderm and germ band stages. Depending on stage and beam diameter (10–30 μm), from 0 to 45 nuclei were exposed to the uv radiation. The doses used, 5 or 10 erg, did not eliminate nuclei or cells at once, but up to 50% of the adult survivors from irradiated eggs carried defects in the thorax. These were scored with reference to the imaginal discs from which the affected structures derive. For each thoracic disc a ...

Unscheduled DNA synthesis after partial UV irradiation of the cell nucleus

Cells of an euploid strain of the Chinese hamster synchronized in the G1 phase were microirradiated in the nucleus with a laser UV microbeam (λ = 257 nm) and pulse-labelled with [3H]thymidine. In autoradiographs of cells fixed immediately after the pulse unscheduled DNA synthesis (UDS) was found restricted to the microirradiated part of the nucleus. The rate of UDS varied with the UV energy applied and the post-irradiation incubation time. In other experiments chromosome preparations were establ...

Isolation, characterization and radioimmunoassay of corticosteroid-binding globulin (CBG) in human serum - clinical significance and comparison to thyroxine-binding globulin (TBG)

Effects of obesity, total fasting and realimentation on L-thyroxine (T4), 3,5,3', - L-triiodothyronine (T3), - 3,3',5'-L-triiodorhyronine (rT3), - thyroxine binding globulin (TBG), cortisol, thyrotophin, cortisol-binding globulin (CBG), transferrin, alpha2-haptoglobin and complement C 3 in serum

Transit times through the cycle phases of jejunal crypt cells of the mouse

Mean transit times as well as variances of the transit times through the individual phases of the cell cycle have been determined for the crypt epithelial cells of the jejunum of the mouse. To achieve this the fraction of labelled mitoses (FLM) technique has been modified by double labelling with [3H] and [14C]thymidine. Mice were given a first injection of [3H]thymidine, and 2 hr later a second injection of [14C]thymidine. This produces a narrow subpopulation of purely 3H-labelled cells at the ...

Automated quantitative analysis of single and double label autoradiographs

A method for the analysis of silver grain content in both single and double label autoradiographs is presented. The total grain area is calculated by counting the number of pixels at which the recorded light intensity in transmission dark field illumination exceeds a selected threshold. The calibration tests included autoradiographs with low (3H- thymidin) and high (3H-desoxyuridin) silver grain density. The results are proportional to the customary visual grain count. For the range of visibly c...

Die blande Struma

Eine mechanische Teil-Indikation kann auch schon bei blander Struma des Stadium I bestehen. Die Indikation auf Wunsch des Patienten ist berechtigt, wenn die Schilddrüsenhormonbehandlung erfolglos oder wenig aussichtsreich ist. Die prophylaktischdiagnostische Operationsindikation wird nach Abwägung von statistischem und individuellem Malignom- und Operationsrisiko gestellt. Letztere Indikation überwiegt heute bei weitem. — Die Kropf-Prophylaxe mit jodiertem Speisesalz könnte die mittlere Strumafr...
