Summary Ribonuclease treatment of rhinovirus-infected human embryo lung cells after cell disruption reveals that double stranded RNA is present in the preparation before nucleic acids are extracted with phenol. This shows that the hydrogen bonding between complementary molecules of viral RNA which occurs in infected cells is not a result of the extraction of RNA with phenol. 相似文献

Cytoplasmic RNA extracted from antigen stimulated immunocompetant cells is transcribed in vitro into DNA by the RNA directed DNA polymerase from avian myeloblastosis virus, in the absence of any added primer. Cytoplasmic RNA from other organs of the same animal, from non-stimulated immunocompetent cells, or from cells in tissue culture is not transcribed in the absence of exogenous primer. 相似文献

Zusammenfassung Aus Virus-infizierten Zellen isoliertes Chromatin wurde mit dem Erythrocytenchromatin verglichen. Die durch Infektion oder Differenzierung verlorene Kapazität des Chromatins der RNS-Syntheseunterstützung wird durch Entfernung eines Teiles des Proteins wieder hergestellt.

The presence of lymphoid cells possessing both kappa and lambda specificities has been observed in the intestinal mucosa of normal subjects. The variability in the number of such cells in different sections of the same sample and in different subjects seems to be a characteristic of this cell population and may reflect the high activity of the immune system in the small intestine. 相似文献

Peripheral T-lymphocytes from patients with infectious mononucleosis are cytotoxic towards target cells from Epstein-Barr virus-genome carrying human lumphoblastoid lines. Thus, these T-cells appear to be sensitized to viral coded determinants. Daudi cells, that carry EBV-genome, but lack HLA antigens are resistant to specific cytolysis in this model. These results suggest direct HLA involvement in the target structure recognized by birus-sensitized cytolytic T-lymphocytes in human. 相似文献
