Plasma lipid levels are important risk factors for the development of atherosclerosis and coronary heart disease. Previous findings have shown that probiotic bacteria exert positive effects on hypercholesterolemia by lowering serum cholesterol and improving lipid profile that, in turn, leads to a reduced risk of coronary heart disease and atherosclerosis.(More)
The early establishment of a complete microbiome has been shown to play an integral part in the development and maintenance of an intact intestine and its immune system, although much remains unknown about the specific mechanisms of immune modulation in newborns. In our study we show in a co-culture model of the undeveloped small intestine that members of(More)
Although the body can synthesize L-arginine, exogenous supplementation may be sometimes necessary, especially in particular conditions which results in depleted endogenous source. Among diseases and states when exogenous supplementation may be necessary are: burns, severe wounds, infections, insufficient circulation, intensive physical activity or(More)
Cell cultures have been used extensively by many scientists in recent decades to study various cell and tissue mechanisms. The use of cell cultures has many advantages over use of in vivo experimental models, but there are also limitations. As skeletal muscle-derived cell cultures become more commonly utilized in studies of muscle regeneration processes the(More)
The use of porcine intestinal cell lines in assessing toxicity of Bacillus cereus probiotics in conjunction with animal challenge trials with toxigenic B. cereus was investigated. Toxigenic and toxin deletion mutants of B. cereus and two probiotic strains (Paciflor and Toyocerin) were examined for bacterial attachment, cytotoxicity and ability to induce(More)
Regeneration of skeletal muscle after injury is limited by scar formation, slow healing time and a high recurrence rate. A therapy based on platelet-rich plasma (PRP) has become a promising lead for tendon and ligament injuries in recent years, however concerns have been raised that PRP-derived TGF-β could contribute to fibrotic remodelling in skeletal(More)
Understanding the host immune response to vaginal exposure to RNA viruses is required to combat sexual transmission of this class of pathogens. In this study, using lymphocytic choriomeningitis virus (LCMV) and Zika virus (ZIKV) in wild-type mice, we show that these viruses replicate in the vaginal mucosa with minimal induction of antiviral interferon and(More)
Corneal wound healing is often affected by TGF-β-mediated fibrosis and scar formation. Guided fibrosis with IGF-1 and antifibrotic substances might maintain corneal transparency. Primary human corneal keratocytes under serum-free conditions were used as a model of corneal stromal wounding, with markers of corneal fibrosis and opacity studied under TGF-β2(More)
The concept of functional and novel foods undoubtedly bears great potential as an asset to human health. However, this very same quest for ever new bioactive ingredients calls for reliable and distinct risk assessment as they may be potentially hazardous to human health. Most of today's methodologies still rely on decades old routines of animal trials and(More)
The intestinal epithelium is composed of diverse cell types, most abundant being the enterocytes. Among other functions, they maintain the intestinal barrier and play a critical role in the absorption of nutrients, drugs and toxins. This study describes the development and characterization of human intestinal epithelial cells (HUIEC), a spontaneously(More)
