Structural features of double-stranded polyribonucleotides required for immunological specificity and interferon induction.
Purified antibody to poly(adenylic acid)-poly(uridylic acid) was used in quantitative microcomplement fixation assays to detect conformational variations among several double-helical polyribonucleotide analogs of poly(adenylic acid)-poly(uridylic acid) or poly(inosinic acid)-poly(cytidylic acid) that had been previously evaluated for their ability to induce interferon. Modification at the furan...
متن کاملStimulation of differentiation of mouse myeloid leukemic cells and induction of interferon in the cells by double-stranded polyribonucleotides.
Mouse myeloid leukemic MI cells can be induced to differentiate into mature macrophages and granulocytes by differentiation-stimulating factor (D-factor) in conditioned medium of mouse peritoneal macrophages. Double-stranded RNA's, such as the copolymers of polyinosinic and polycytidylic acids and polyadenylic and polyuridylic acids, could not alone induce differentiation of the cells, but enha...
متن کاملInterferon induction by adenoviruses.
All human, simian, bovine and avian adenovirus types tested so far and the canine hepatitis virus induce interferon production in chick cells. This finding indicated this property to be characteristic for viruses belonging to the adenovirus group. Trypsin treatment, which had no effect upon the infectivity, diminished or eliminated the interferon-inducing abilities of crude adenoviruses, and th...
متن کاملInterferon Induction by Viruses
Interferons are proteins of cellular origin capable of conferring virus resistance to vertebrate cells. Most cells do not produce interferons except in response to proper stimulation. Clearly, the stimulation of interferon production encompasses two phenomena. When stimulated, some cell systems produce their interferons by synthesizing new proteins. Other cell systems do not require the synthes...
متن کاملMolecular Aspects of Interferon Induction by Viruses
Virus-induced interferon formation depends on the presence within the cell of a viral ribonucleic acid. This RNA may either be double stranded or, in certain cases, single stranded. The double-stranded RNA can be derived from a virus, such as reovirus, which contains this type of RNA, or it may be synthesized within the cell using viral single-stranded RNA as a template. Single-stranded RNA mus...
