The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a fast spreading virus leading to the development of Disease-2019 (COVID-19). and critical cases are characterized by damage respiratory system, endothelial inflammation, multiple organ failure triggered an excessive production proinflammatory cytokines, culminating in high number deaths all over world. Sedentarism induces worse, continuous, progressive consequences health. On other hand, physical activity provides benefits health improves low-grade systemic inflammation. aim this review elucidate effects fitness, immune defense, its contribution mitigate severe inflammatory response mediated SARS-CoV-2. Physical exercise effective therapeutic strategy SARS-CoV-2 infection. In sense, studies have shown that acute myokines secreted tissues into bloodstream, supporting modulatory effect. Therefore, maintaining influence balance system increases vigilance, also might promote potent against infectious diseases chronic associated with forms COVID-19. Protocols maintain practice suggested been strongly established, such as home-based (HBE) outdoor-based (OBE). regard, HBE help reduce levels inactivity, bed rest, sitting time, impacting on adherence activity, promoting related exercise, attracting patients different stages treatment for parallel, OBE must improve health, but prevent COVID-19 outcomes populations. conclusion, or models can be progress infection, coadjutant therapy at ages conditions.

Reactive oxygen species (ROS) are fundamental for macrophages to eliminate invasive microorganisms. However, as observed in nonphagocytic cells, ROS play essential roles processes that different from pathogen killing, signal transduction, differentiation, and gene expression. The outcomes of these events likely depend on the specific subcellular site formation, well duration extent production. While excessive accumulation has long been appreciated its detrimental effects, there is now a deeper understanding their signaling molecules. This could explain failure "all or none" pharmacologic approach with global antioxidants treat several diseases.

Abstract Molecular oxygen (O 2 ) is essential for most biological reactions in mammalian cells. When the intracellular content decreases, it called hypoxia. The process of hypoxia linked to several processes, including pathogenic microbe infection, metabolic adaptation, cancer, acute and chronic diseases, other stress responses. mechanism underlying cells respond changes mediate subsequent signal response central question during Hypoxia-inducible factors (HIFs) sense regulate expressions a series downstream genes expression, which participate multiple processes cell metabolism, growth/death, proliferation, glycolysis, immune response, tumorigenesis, metastasis. Importantly, signaling also interacts with cellular pathways, such as phosphoinositide 3-kinase (PI3K)-mammalian target rapamycin (mTOR) signaling, nuclear factor kappa-B (NF-κB) pathway, extracellular signal-regulated kinases (ERK) endoplasmic reticulum (ER) stress. This paper systematically reviews mechanisms activation, control HIF function human health diseases. In addition, therapeutic targets involved balance diseases are summarized highlighted, would provide novel strategies design development drugs.
