Inhibition of multiplication of Mycobacterium leprae by polyinosinic-polycytidylic acid.
Contrary to the results of an earlier study in which polyinosinic-polycytidylic acid [poly(I:C)] administered intraperitoneally to mice had no effect on multiplication of Mycobacterium leprae in the mouse footpad, the local administration of poly(I:C) every 12 h for 15 doses during logarithmic multiplication was found both to inhibit bacterial multiplication and to produce high tissue levels of...
متن کاملInhibition of cancer cell growth by polyinosinic-polycytidylic acid/cationic liposome complex: a new biological activity.
A complex of polyinosinic-polycytidylic acid [poly(I) x poly(C)] and cationic liposome (LIC) inhibited the growth of many tumor cell lines at low concentration in vitro, but poly(I) x poly(C) alone had no such antiproliferative effect. The IC50 values of LIC against the tumor cells ranged from 0.1 to 1000 ng/ml. LIC had strong cytotoxic effects on malignant cells of epithelial and fibroblastic ...
متن کاملInhibition of herpes simplex virus strains isolated from herpetic keratitis by polyinosinic acid-polycytidylic acid.
Fifty strains of herpes simplex virus, isolated from patients with herpetic keratitis, were examined in vitro for susceptibility to polyinosinic acid-polycytidylic acid [poly(I:C)] in the presence of a constant concentration of diethylaminoethyl-dextran. The minimal inhibitory concentration of poly(I:C) for 44 of these strains ranged from 0.0001 to 0.1 mug/ml; for the remaining six strains, the...
متن کاملVariable response of human cells to polyinosinic-polycytidylic acid.
Human cells derived from various organs of a single embryo responded variably to polyinosinic-polycytidylic acid with respect to induction of antiviral resistance and interferon.
متن کاملControl of interferon synthesis: effect of diethylaminoethyl-dextran on induction by polyinosinic-polycytidylic acid.
Interferon production in cultures of rabbit kidney cells (RKC) stimulated with 10 to 250 mug of polyinosinic-polycytidylic acid (poly I.poly C) per ml peaked at 3 to 4 hr after the exposure of cells to inducer and rapidly declined thereafter. On the other hand, RKC stimulated with poly I.poly C (10 or 2 mug/ml) in the presence of diethylaminoethyl (DEAE)-dextran (100 or 20 mug/ml, respectively)...
