Summary
The transformation to blast cells and the nucleic acid and protein synthesis of unstimulated and stimulated lymphocytes has been investigated in vitro. Unstimulated lymphocytes showed a low and relatively constant level of RNA and protein synthesis, whereas no DNA synthesis could be observed. PHA, Pokeweed, Streptolysin O and tuberculin stimulated normal lymphocytes exhibited a typical response in RNA, DNA and protein synthesis in cultures up to 9 days. With Pokeweed and specific mitogens the stimulation of DNA synthesis was much more pronounced as compared to RNA synthesis.
Zeammenfassung
Es wurde die Transformation zu Blastzellen und die Nucleinsäure- und Proteinsynthese unstimulierter und stimulierter Lymphocyten von Gesunden in vitro untersucht. Unstimulierte Lymphocyten zeigten einen niedrigen und relativ konstanten Basisstoffwechsel der makromolekularen RNS und der Zellproteine, ohne daß sich eine DNS-Synthese nachweisen ließ. Mit Phythämagglutinin, Pokeweed-Extrakt, Streptolysin O und Tuberkulin stimulierte normale Lymphocyten ließen einen typischen Ablauf ihrer RNS-, DNS- und Proteinsynthese in Kulturen bis zu 9 Tagen erkennen. Bei Pokeweed-Mitogen und spezifischen Mitogenen war die DNS-Synthese im Verhältnis zum RNS-Stoffwechsel stärker ausgeprägt.
