Protozoan Parasites and Type I IFNs
For many years, the role of interferon (IFN)-I has been characterized primarily in the context of viral infections. However, regulatory functions mediated by IFN-I have also been described against bacterial infections and in tumor immunology. Only recently, the interest in understanding the immune functions mediated by IFN-I has dramatically increased in the field of protozoan infections. In th...
متن کاملGetting “Inside” Type I IFNs: Type I IFNs in Intracellular Bacterial Infections
Type I interferons represent a unique and complex group of cytokines, serving many purposes during innate and adaptive immunity. Discovered in the context of viral infections, type I IFNs are now known to have myriad effects in infectious and autoimmune disease settings. Type I IFN signaling during bacterial infections is dependent on many factors including whether the infecting bacterium is in...
متن کاملProtozoan Parasites
When viewed from the top, Trichodina is circular; side views of the organism reveal a saucer or dome shape (Fig. 1). It has three rings of cilia (small, hair-like projections) encircling its body and oral cavity, which are used for locomotion and feeding. Its body is supported by a rigid ring of interconnected discs called a chitinoid or denticular ring (Fig. 2). Each disc has a thorn-like inne...
متن کاملFoodborne protozoan parasites.
This report addresses Cryptosporidium, Giardia, Cyclospora, and more briefly, Toxoplasma as the main parasitic protozoa of concern to food production worldwide. Other parasitic protozoa may be spread in food or water but are not considered as great a risk to food manufacture. The protozoan parasites Cryptosporidium, Giardia, and Cyclospora have proven potential to cause waterborne and foodborne...
متن کاملType I-IFNs control GVHD and GVL responses after transplantation.
Although the effects of type II-IFN (IFN-γ) on GVHD and leukemia relapse are well studied, the effects of type I-interferon (type I-IFN, IFN-α/β) remain unclear. We investigated this using type I-IFN receptor-deficient mice and exogenous IFN-α administration in established models of GVHD and GVL. Type I-IFN signaling in host tissue prevented severe colon-targeted GVHD in CD4-dependent models of...
