Introduction. Under normal conditions, oxidative stress and proinflammatory processes are tightly controlled. However, during neuroinflammation and overproduction of reactive oxygen species (ROS), homeostasis is disrup­ted, which may lead to development of Alzheimer’s disease, Parkinson’s disease and other neurodegenerative disorders. Inflammatory processes may result in neurodegenerative disorders. Sulforaphane is an isothiocyanate compound which has potential for treatment of neurodegenerative disorders. Its therapeutic potential is based on the ability to activate transcription of genes, that regulate protective cellular mechanisms. The importance of stu­dying sulforaphane as a neuroprotector is based on the fact, that dementias are the seventh leading cause of death glo­bally and actively progress due to aging of human population. In this review, the anti-inflammatory effects of sulforaphane in the brain and its use as a potential neuroprotector in the treatment of neurodegenerative diseases are discussed. The aim of the study – to review available literature sources on the potential use of sulforaphane to prevent or mitigate neuroinflammation. Conclusions. Economic and technological development of mankind and the improvement of the general qua­lity of life leads to prolongation of human life. But, achievements of longevity give new challenges to humanity. In young age and early adulthood, the organisms can relatively easily maintain homeostasis, then in old age intensification of oxidative stress and inflammatory processes can lead to the development of dementias and mental disorders. What should we do now to save clear mind in old age? In this review, sulforaphane is considered to be a potential neuroprotector. Biologically active supplements and drugs containing sulforaphane can weaken up inflammatory processes in the brain and in the body in general, and therefore they can be used for prevention and treatment of neurodegenerative diseases.

There is increasing evidence that multiple sclerosis (MS) is not only characterized by immune mediated inflammatory reactions but also by neurodegenerative processes. In neurodegenerative diseases, neuronal and axonal loss is mediated by oxidative stress and excitotoxicity which constitute a final common toxic pathway. Importantly, peroxynitrite is the key mediator of those two intertwined pathomechanisms. In MS, peroxynitrite is consistently associated with active lesions and produces highly toxic nitrating and oxidizing radical species that alter lipid, protein, DNA and mitochondrial structures and functions. During the remitting phase, peroxynitrite participates to neuron and oligodendrocyte damage in association with inflammatory processes. During the chronic phase, peroxynitrite contributes to self-perpetuating mechanisms responsible for disease progression. Neutralization of oxidative stress and excitotoxicity, and in particular of peroxynitrite derived free radicals, might represent a therapeutic approach to provide neuroprotection in MS.

SummaryThe initiating event of atherogenesis is thought to be an injury to the vessel wall resulting in endothelial dysfunction. This is followed by key features of atherosclerotic plaque formation such as inflammatory responses, cell proliferation and remodeling of the vasculature, finally leading to vascular lesion formation, plaque rupture, thrombosis and tissue infarction. A causative relationship exists between these events and oxidative stress in the vessel wall. Besides leukocytes, vascular cells are a potent source of oxygen-derived free radicals. Oxidants exert mitogenic effects that are partially mediated through generation of growth factors. Mitogens, on the other hand, are potent stimulators of oxidant generation, indicating a putative self-perpetuating mechanism of atherogenesis. Oxidants influence the balance of the coagulation system towards platelet aggregation and thrombus formation. Therapeutic approaches by means of antioxidants are promising in both experimental and clinical designs. However, additional clinical trials are necessary to assess the role of antioxidants in cardiovascular disease.

Background. Many neurodegenerative diseases such as Alzheimer’s disease are associated with oxidative stress. Therefore, antioxidant therapy has been suggested for the prevention and treatment of neurodegenerative diseases. Objective. We investigated the ability of the antioxidant Antia to exert a protective effect against sporadic Alzheimer’s disease (SAD) induced in mice. Antia is a natural product that is extracted from the edible yamabushitake mushroom, the gotsukora and kothala himbutu plants, diosgenin (an extract from wild yam tubers), and amla (Indian gooseberry) after treatment with MRN-100. Methods. Single intracerebroventricular (ICV) injection of streptozotocin (STZ) (3 mg/kg) was used for induction of SAD in mice. Antia was injected intraperitoneally (i.p.) in 3 doses (25, 50, and 100 mg/kg/day) for 21 days. Neurobehavioral tests were conducted within 24 h after the last day of injection. Afterwards, mice were sacrificed and their hippocampi were rapidly excised, weighed, and homogenized to be used for measuring biochemical parameters. Results. Treatment with Antia significantly improved mice performance in the Morris water maze. In addition, biochemical analysis showed that Antia exerted a protective effect for several compounds, including GSH, MDA, NF-κB, IL-6, TNF-α, and amyloid β. Further studies with western blot showed the protective effect of Antia for the JAK2/STAT3 pathway. Conclusions. Antia exerts a significant protection against cognitive dysfunction induced by ICV-STZ injection. This effect is achieved through targeting of the amyloidogenic, inflammatory, and oxidative stress pathways. The JAK2/STAT3 pathway plays a protective role for neuroinflammatory and neurodegenerative diseases such as SAD.

With the world’s population ageing, the incidence of Parkinson’s disease (PD) is on the rise. In recent years, inflammatory processes have emerged as prominent contributors to the pathology of PD. There is great evidence that microglia have a significant neuroprotective role, and that impaired and over activated microglial phenotypes are present in brains of PD patients. Thereby, PD progression is potentially driven by a vicious cycle between dying neurons and microglia through the instigation of oxidative stress, mitophagy and autophagy dysfunctions, a-synuclein accumulation, and pro-inflammatory cytokine release. Hence, investigating the involvement of microglia is of great importance for future research and treatment of PD. The purpose of this review is to highlight recent findings concerning the microglia-neuronal interplay in PD with a focus on human postmortem immunohistochemistry and single-cell studies, their relation to animal and iPSC-derived models, newly emerging technologies, and the resulting potential of new anti-inflammatory therapies for PD.

Oxidative stress has been associated with many pathologies, in both human and animal medicine. Damage to tissue components such as lipids is a defining feature of oxidative stress and can lead to the generation of many oxidized products, including isoprostanes (IsoP). First recognized in the early 1990s, IsoP are formed in numerous biological fluids and tissues, chemically stable, and easily measured by noninvasive means. Additionally, IsoP are highly specific indicators of lipid peroxidation and thereby are regarded as excellent biomarkers of oxidative stress. Although there have been many advancements in the detection and use of IsoP as a biomarker, there is still a paucity of knowledge regarding the biological activity of these molecules and their potential roles in pathology of oxidative stress. Furthermore, the use of IsoP has been limited in veterinary species thus far and represents an avenue of opportunity for clinical applications in veterinary practice. Examples of clinical applications of IsoP in veterinary medicine include use as a novel biomarker to guide treatment recommendations or as a target to mitigate inflammatory processes. This review will discuss the history, biosynthesis, measurement, use as a biomarker, and biological action of IsoP, particularly in the context of veterinary medicine.
