Deubiquitinating enzymes (DUBs) play an important role in regulating a variety of eukaryotic processes. In this context, exploring the role of deubiquitination in Leishmania infantum could be a promising alternative to search new therapeutic targets for leishmaniasis. Here we present the first characterization of a DUB from L. infantum, otubain (OtuLi), and its localization within parasite. The...

A number of diseases that lead to injury of the central nervous system are caused by oxidative stress and inflammation in the brain. In this study, NNMBS275, consisting of the ethanol extract of Viola patrinii, showed potent antioxidative and anti-inflammatory activity in murine hippocampal HT22 cells and BV2 microglia. NNMBS275 increased cellular resistance to oxidative injury caused by glutam...

Elevated levels of proinflammatory cytokines associated with infection and inflammation can modulate cytochrome P450 enzymes, leading to potential disease-drug interactions and altered small-molecule drug disposition. We established a human-derived hepatocyte-Kupffer cell (Hep:KC) coculture model to assess the indirect cytokine impact on hepatocytes through stimulation of KC-mediated cytokine r...

Phenoconversion transiently converts genotypic extensive metabolizers (EMs) into phenotypic poor metabolizers (PMs) of drugs, potentially with corresponding changes in clinical response. This phenomenon, typically resulting from coadministration of medications that inhibit certain drug metabolizing enzymes (DMEs), is especially well documented for enzymes of the cytochrome P450 family. Nonclini...

Essential oils from different plant species were found to contain compounds exhibiting anti-inflammatory effects with the potential be a valid alternative conventional chemotherapy that is limited in long-term use due its serious side effects. Generally, first mechanism by which an organism counteracts injurious stimuli inflammation, considered part of innate immune system. Periodontitis infect...

Chronic inflammation is a common phenomenon present in the background of multiple neurodegenerative diseases, including Alzheimer's disease (AD). The arachidonic acid pathway overproduces proinflammatory eicosanoids during these states and glial cells in the brain gradually lose their vital functions of protecting and supporting neurons. In this study, the role of different key enzymes of the e...

Oxidative stress plays a pivotal role in the development of diabetes complications, both microvascular and cardiovascular. The metabolic abnormalities of diabetes cause mitochondrial superoxide overproduction in endothelial cells of both large and small vessels, as well as in the myocardium. This increased superoxide production causes the activation of 5 major pathways involved in the pathogene...

Type 2 phosphatidylinositol-5-phosphate 4-kinase (PI5P4K) converts phosphatidylinositol-5-phosphate to phosphatidylinositol-4,5-bisphosphate. Mammals have three enzymes PI5P4Kα, PI5P4Kβ, and PI5P4Kγ, and these enzymes have been implicated in metabolic control, growth control, and a variety of stress responses. Here, we show that mice with germline deletion of type 2 phosphatidylinositol-5-phosp...

Calotropis procera (commonly known as Swallow wort) is described in the Ayurvedic literature for treatment of inflammation and arthritic disorders. Therefore, present work, antiarthritic activity potential fractions wort leaf was evaluated compared with standards (indomethacin ibuprofen). This study designed Wistar rats investigation acute toxicity wort. Arthritis induced by injecting 0.1 mL Fr...
