BACKGROUND We hypothesized that endothelial cells having distinct mitochondrial genetic backgrounds would show variation in mitochondrial function and oxidative stress markers concordant with known differential cardiovascular disease susceptibilities. To test this hypothesis, mitochondrial bioenergetics were determined in endothelial cells from healthy individuals with African versus European m...
Rhizopus oryzae is the most common cause of zygomycosis, a life-threatening infection that usually occurs in immunocompromised patients. A characteristic hallmark of zygomycosis is angioinvasion by the fungus, resulting in thrombosis and subsequent tissue necrosis. Interactions between R. oryzae and vascular endothelial cells are therefore likely of central importance to the organism's pathogen...
The coronavirus infection, COVID-19, caused by SARS-CoV-2 is associated not only with a wide range of respiratory syndromes, but also pronounced destructive effect on the blood vessels whole body. Age and concomitant pathology predispose to more severe course disease. Endothelial damage, widespread vasculitis thrombosis can be distinguished as general nonspecific pathomorphological changes deve...
Damage to endothelial cells is the common feature of vascular disorders associated with hematopoietic stem cell transplantation (HSCT). Elevated numbers of circulating endothelial cells reflect the extent of endothelial damage in a variety of disorders but their use in HSCT has not been investigated so far. We studied 39 patients undergoing allogeneic HSCT with different conditioning regimens a...
BACKGROUND Amyotrophic Lateral Sclerosis (ALS) treatment is complicated by the various mechanisms underlying motor neuron degeneration. Recent studies showed that the blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) are compromised in an animal model of ALS due to endothelial cell degeneration. A later study demonstrated a loss of endothelium integrity in the spinal cords of ALS p...
Phagocytosis of microorganisms by polymorphonuclear leukocytes (PMN) is accompanied by inadvertent extracellular release of microbicidal products; this could result in tissue damage. We investigated whether PMN damages endothelial cells when phagocytosis of Staphylococcus aureus occurs on the endothelial surface and how this damage might be modulated. Damage was assayed by the measurement of ce...
In recent years, injuries induced by explosive blast have got more and more attention owing to weapon development and frequent terrorist activities. Tear, bleeding and edema of tissues and organs are the main manifestations of blast shock wave damage. Vascular endothelial barrier is the main defense of tissues and organs' integrity. This article aims to discuss possible mechanisms of endothelia...
Most cancer patients are treated with radiotherapy, but the treatment can also damage the surrounding normal tissue. Radiotherapy side-effects diminish patients' quality of life, yet effective biological interventions for normal tissue damage are lacking. Protecting microvascular endothelial cells from the effects of irradiation is emerging as a targeted damage-reduction strategy. We illustrate...
