Interferon and Interferon Inducers in Protozoal Infections
Several interferon inducers (Newcastle disease virus, statolon, and poly rI:poly rC) as well as exogenous mouse interferon protect mice from sporozoite-induced Plasmodium berghei malaria, as long as they are administered before the end of the preerythrocytic phase of development of the parasite. The protective effect of the interferon inducers was related to their interferon-inducing effect; th...
متن کاملEffect of interferon inducers and interferon on bacterial infections.
The effect of interferon inducers and exogenous L-cell interferon on the infection of mice by Pasteurella tularensis or Diplococcus pneumoniae was investigated. The results indicate that the degree of protection is dependent on the type of inducer used. A variety of defense mechanisms with limited nonspecific activity appear to be involved.
متن کاملNonviral Interferon Inducers
Interferon production can be stimulated by a great variety of microbial and nonmicrobial agents other than viruses. The nonmicrobial inducers can be divided into polyanions, mitogens, and a miscellaneous category including the various endotoxins and antibiotics. The polyanions appear to require a stable, high molecular weight backbone and a high density of free anionic groups whether they are p...
متن کاملInterferon and Interferon Inducers in the Treatment of Malignancies
The mechanism of the antitumor action of polyinosinic-polycytidylic acid is probably multifaceted. The compound induces the synthesis of interferon, and interferon probably is active against some tumors. Poly I:poly C alters protein and RNA synthesis in tissue culture. It specifically inhibits such macromolecule synthesis in tumors in vivo, while having less inhibitory action on synthesis in no...
متن کاملMycoplasma-mediated hyporeactivity to various interferon inducers.
Three strains of Mycoplasma arthritidis were shown to induce marked hyporeactivity in mice to interferon induction by both Newcastle disease virus and poly(I:C). In contrast, the interferon response of mice to tilorone was only partially suppressed by pretreatment of the animals with mycoplasms. Hyporeactivity to Newcastle disease virus was maximal 1 and 3 days after mycoplasms treatment, but t...
