Nepeta (Lamiaceae) is an important genus with beneficial medicinal properties. N. sintenisiiBornm. has been used in folk medicine of Iran to cure various diseases. We investigated theanti-melanogenesis effects of n-hexane, MeOH, CH2Cl2, n-BuOH, EtOAc, and H2O extractsisolated from the plant in B16 melanoma cells. Various assays including cytotoxicity, mushroomtyrosinase inhibition, inhibition o...
The role of the surface properties nanoparticles in serum protein adsorption, cellular uptake and cytotoxicity is reported. regulate their ability to adsorb proteins determine biological outcomes.
To assess general cytotoxic effector cell capabilities by peripheral blood mononuclear cells from patients with active malaria infections, we examined antibody-dependent cellular cytotoxicity, spontaneous cell-mediated cytotoxicity, and lectin-induced cellular cytotoxicity by using human and chicken erythrocyte, Chang cell line, and K562 cell line targets. By using human erythrocyte and Change ...
cyte (HRBC) targets in suspension cultures indicative of abnormal intracellular postphagocytic killing. However, when phagocytosis was prevented by using a monolayer of antibody-coated HRBC targets, CGD monocytes, neutrophils, and lymphocytes exhibited normal ADCC activity. Similarly, antibody-coated HRBC targets in suspension could be lysed normally by CGD effector cells when phagocytosis was ...
by discovering how chemical compounds/xenobiotics cytotoxicity is affected when their metabolic pathways are inhibited or activated, the metabolic pathways that activate versus detoxify chemical compound can be identified. reactive metabolites contributing to cytotoxicity can also be identified. in this lecture, the pretreatment of inhibitors and activators of xenobiotic metabolizing enzymes as...
It has been proposed that organic nitrates such as glyceryl trinitrate (GTN), used in the treatment of cardiovascular diseases, act by producing nitric oxide (NO). However, the biochemical pathway for NO formation from GTN is not well understood. In the present study, we showed that nitrate formation from GTN, by isolated rat hepatocytes, was inhibited about 50% when cellular glutathione w...
Collective evidence supporting a role of Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC) in controlling HIV-1 transmission and disease progression emerged in the last few years. Non-neutralizing antibodies (nnAbs) recognizing conserved CD4-induced epitopes on Env and able to mediate potent ADCC against HIV-1-infected cells exposing Env in its CD4-bound conformation have been shown to be pr...
