In order to improve the postoperative prognosis of gastric cancer patients we have performed preoperative endoscopic intratumoral administration of various biological response modifiers. In the present study we have investigated the kinetics and the immune response augmenting effect of intratumorally injected PSK, a protein-bound polysaccharide preparation, by immunohistochemical methods using ...
Thymosin alpha 1 (Tα1) is an important immunomodulating agent with various clinical applications. The natural form of Tα1 is Nα -acetylated, which was supposed to be related to in vivo stability of the hormone. In this study, fusion protein Tα1-HSA was constructed and expressed in Pichia pastoris. RimJ, a Nα -acetyltransferase from E.coli, was also overexpressed and purified to homogeneity. In ...
Interferon-stimulated genes fulfill innate antiviral effector functions. Among them, tetherin (THN) blocks the release of many enveloped viruses from infected cells. Vaccinia virus (VACV) encodes immune modulators interfering with antiviral host responses. Therefore, it was tempting to study a potential VACV-THN interaction. Remarkably, THN expression did not inhibit VACV release and replicatio...
The sphingomyelinase (Sphmase) activity degrading sphingomyelin (Sphm) monolayers shows a slow-reaction latency period before exhibiting constant rate catalysis. These two kinetic regions are regulated independently by the lateral surface pressure and by lipids that are biomodulators of cell function such as ceramide, glycosphingolipids, fatty acids, and lysophospholipids. Knowledge of the inte...
64 out-patients suffering from recurrent UTI were treated under double-blind conditions with one capsule daily of either the biological response modifier OM-8930 or the placebo for 3 months, followed by a 3-month observation period. Dysuria, bacteriuria, leucocyturia and antibiotic or chemotherapeutic consumption showed a significant reduction under OM-8930 in comparison with the placebo. As to...
BACKGROUND AND AIMS Severe influenza A(H1N1)pdm2009 virus infection cases are characterized by sustained immune activation during influenza pandemics. Seasonal flu data suggest that immune mediators could be modified by wave-related changes. Our aim was to determine the behavior of soluble and cell-related mediators in two waves at the epicenter of the 2009 influenza pandemic. METHODS Leukocy...
Alzheimer's disease (AD) is a familiar neurodegenerative disease in the elderly. In this paper, we will review current viewpoints of microglial activation, inflammatory regulatory systems, and their relationship with AD pathology and etiology. Microglia cells are macrophage and representative of the innate immune system in brain. AD brain is marked by obvious inflammatory features, in which mic...
