Strenuous physical exercise induces muscle fibers damage and non-specific inflammatory response. Activated by inflammatory process cells may serve as the source of wide spectrum of inflammatory mediators and growth factors. Namely Platelet Derived Growth Factor (PDGF), Transforming Growth Factor-beta (TGF-beta) and Vascular Endothelial Growth Factor (VEGF)(More)
Interleukin-6 (IL-6) is the main cytokine involved in the induction of acute phase response, which includes synthesis of certain proteins in the liver, one of which is C-reactive protein (CRP). The aim of this study was to assess the impact of IL-6 released during physical exercise on CRP generation in healthy male athletes. Fourteen young cyclists were(More)
BACKGROUND Physical exercise benefits the heart, but the mechanism is not understood. The mechanism of muscle plasticity after physical training is also unclear. The proangiogenic and mitogenic activity of PDGF and VEGF could be involved in both processes. This study investigated the influence of a single bout of acute exercise on the PDGF-AA and VEGF-A(More)
One of the signs of advancing age in humans is sarcopenia. The term is used to define the loss of muscle mass and strength that occurs with ageing. Sarcopenia contributes to the decreased capacity of independent living and increased amounts of traumas. Numbers of mechanisms are proposed as a cause of sarcopenia, including changes in protein metabolism,(More)
Adipose tissue is an important organ that produces and secretes hormones and cytokines, including TGF-β1, PDGF-AA, and VEGF-A. The goal of the present study was to investigate the influence of a single session of acute exercise, as well as the prolonged endurance training on the production of TGF-β1, PDGF-AA, and VEGF-A in the subcutaneous white adipose(More)
The serum level of the transforming growth factor-beta1 (TGF-beta1) is elevated after acute bouts of exercise and prolonged training, as well as after myocardial infarction. However, the source of this increase remains unclear. Contracting skeletal muscles are known to be the source of many cytokines. To determine whether skeletal or heart muscles produce(More)
Irisin induces the browning of adipose tissue. The goal of this study was to investigate the influence of acute exercise in untrained and trained rats and endurance training on FNDC5 mRNA and irisin levels in white and red skeletal muscle and serum. Rats (n=60) were randomly divided into two groups: untrained and trained (subjected to 6-week endurance(More)
We examined the serum levels of IL-6, IL-8, TNF, IL-6R, TNF-R1, and CRP and the dynamics of changes in these levels according to age. The study included healthy individuals of 20–90 years of age. Participants were divided into subgroups based on their decade of life, and into subgroups of ≥65 or <65 years. Serum cytokine levels were assayed by ELISA, and(More)
Indomethacin is a nonsteroidal anti-inflammatory drug used frequently to control chronic or temporary pain. In the kidney, indomethacin decreases medullary and cortical perfusion, resulting in hypoxia. Kidney hypoxia has many effects, including changes in gene expression, and is a strong stimulus for angiogenesis. Other angiogenic factors include vascular(More)
Beta2-microglobulin (beta2M) is the light chain of the class I HLA molecule. The serum level of beta2M is elevated in various diseases including lymphoma, inflammation, viral infections and chronic renal dysfunction. The present study addressed the possible influence of beta2M on T lymphocyte activation in vitro. Peripheral blood mononuclear cells from a(More)
