Anti-inflammatory properties of Type I interferons

Production of type I interferons

Plasmacytoid dendritic cells (pDCs) are specialized producers of type I interferons (IFNs) that respond to most viruses. Because of their antiviral activity and regulatory functions in innate and adaptive immunity, type I IFNs are important not only for antiviral resistance but also in other types of infections and in immune pathology. Here we discuss recent data that begin to reveal the unique...

Weak Anti-inflammatory and Anti-cancer Properties of Saffron

Background and objectives: Positive role of saffron in human health promotion has been investigated in widespread researches. Anticancer property, neuroprotection, protection of cardiovascular system and several positive properties are reported for saffron customers. The aim of this study was assessment of saffron weakness against light damage in rat retina. Methods:</s...

Type I interferons regulate inflammatory cell trafficking and macrophage inflammatory protein 1alpha delivery to the liver.

Macrophage inflammatory protein 1alpha (MIP-1alpha, CCL3) is critical for liver NK cell inflammation and delivery of IFN-gamma to mediate downstream protective responses against murine cytomegalovirus (MCMV) infections. This system was used to evaluate the upstream contribution of the type 1 IFNs, IFN-alpha/beta, in promotion of MIP-1alpha production. Mice deficient in IFN-alpha/beta functions,...

Differential Effects of the Type I Interferons

Induction of type I interferons by bacteria.

Type I interferons (IFNs) are secreted cytokines that orchestrate diverse immune responses to infection. Although typically considered to be most important in the response to viruses, type I IFNs are also induced by most, if not all, bacterial pathogens. Although diverse mechanisms have been described, bacterial induction of type I IFNs occurs upon stimulation of two main pathways: (i) Toll-lik...
