This review summarizes our current knowledge on the innate and adaptive immune responses induced by hepatitis C virus, and on the genetic polymorphisms that may determine the outcome of the disease. In addition, the authors discuss the role of reactive oxygen species and oxidative stress in hepatitis C virus-related pathogenic processess, such as hepatitis, fibrosis, hepatocellular carcinoma, steatosis and insulin resistance.

The paper is devoted to an analysis of the problem of the significance and mechanisms of inflammation and oxidative stress participation in the development of cardiovascular pathology, first of all – in heart and vascular wall damaging and remodeling and in the development of arterial hypertension. An interrelation is traced between the reninangiotensin, sympathoadrenal and immune systems in the development of oxidative stress as a component of innate and adaptive immune responses.

The coronavirus disease 2019 (COVID-19) pandemic continues to burden healthcare systems worldwide. COVID-19 symptoms are highly heterogeneous, and the patient may be asymptomatic or may present with mild to severe or fatal symptoms. Factors, such as age, sex, and comorbidities, are key determinants of illness severity and progression. Aging is accompanied by multiple deficiencies in interferon production by dendritic cells or macrophages in response to viral infections, resulting in dysregulation of inflammatory immune responses and excess oxidative stress. Age-related dysregulation of immune function may cause a more obvious pathophysiological response to SARS-CoV-2 infection in elderly patients and may accelerate the risk of biological aging, even after recovery. For more favorable treatment outcomes, inhibiting viral replication and dampening inflammatory and oxidative responses before induction of an overt cytokine storm is crucial. Resveratrol is a potent antioxidant with antiviral activity. Herein, we describe the reasons for impaired interferon production, owing to aging, and the impact of aging on innate and adaptive immune responses to infection, which leads to inflammation distress and immunosuppression, thereby causing fulminant disease. Additionally, the molecular mechanism by which resveratrol could reverse a state of excessive basal inflammatory and oxidative stress and low antiviral immunity is discussed.

Abstract Hexavalent chromium (Cr (VI)) is a very common and harmful heavy metal pollutant in the world. However, the responses of Cr (VI) to aquatic environmental toxicants have not been well described. In this study, we evaluated the waterborne Cr (VI) [ 0 mg/L (C1), 0.5 mg/L (C2), 1 mg/L (C3), 2 mg/L (C4)] exposed chronically to Channa argus. After 14 and 28 days, we measured biochemical parameters, Cr (VI) accumulation, antioxidant activity and immune response in the serum, liver and gill, respectively. Our results shown that Cr (VI) accumulation will occur in certain tissues as the time of exposure in water prolongs, and the biochemical parameters in the serum will increase. Antioxidant enzymes (catalase, superoxide dismutase and glutathione peroxidase) gradually decreased with the increasing time of Cr (VI) concentration, while the malondialdehyde concentration increases. In addition, in the immune response, cortisol, aminotransferase (ALT), aspartate aminotransferases (AST), alkaline phosphatase (AKP), immunoglobulin M increase, but lysozyme decrease. These results indicated that exposure to waterborne Cr (VI) can exert adverse effects in C. argus by inducing Cr (VI) accumulation, immune responses and oxidative stress.
