Administration of a Synbiotic to Free-Living Elderly and Evaluation of Serum Cytokines. A Pilot Study
2010
Ten free-living elderly were administered with a synbiotic [fermented milk containing Lactobacillus rhamnosus Gorbach and Goldin (LGG)] and oligofructose as a prebiotic for one month. Serum cytokines were evaluated before (T(0)) and after (T(1)) synbiotic administration. At T(0), values of Interleukin (IL)-12, IL-6, IL-10, IL-1beta and Tumor Necrosis Factor (TNF)-alpha were lower than normal controls, with the exception of IL-8, thus confirming previous results on the impairment of both innate and adaptive responses in elderly. At T(1), the synbiotic was able to significantly increase, depressed values of IL-1, IL-6 and IL-8 with a trend to a modest increase for the restant cytokines. In co…
Taking Advantage of Viral Immune Evasion: Virus-Derived Proteins Represent Novel Biopharmaceuticals
2006
In healthy individuals, natural and adaptive immune responses are able to control virus entry into the host. In particular, CD8(+)-mediated cytotoxicity, sustained by the intervention of CD4+ cells, represents the major key event leading to virus eradication. On the other hand, viruses are able to evade from host immune response via several mechanisms, and special emphasis will be placed on hepatitis C virus and chronic Epstein-Barr infections also in view of personal data. Virokines, viroreceptors, and serpins greatly contribute to viral immune escape, and, among virokines, interleukin (IL)-10 has been object of intensive studies. Finally, all these products have been used as biopharmaceut…
