Abstract
2-Hexadecenal (2-HD)-a biologically active long-chain fatty aldehyde formed in organism enzymatically or nonenzymatically in the reaction of free-radical destruction of sphingolipids under the action of hypochlorous acid, producing by myeloperoxidase. This research aimed to study 2-HD effects on polymorphonuclear leukocytes' (PMNLs) functions. It has been shown that at submicromolar concentrations, 2-HD causes an elevation in ROS production by PMNLs. It has been found that such effect is associated with signal transduction pathways modification and expressed in elevation of NADPH oxidase, MPO, and JNK-MAPK contributions to this process. At higher concentrations, 2-HD induces apoptosis, which correlates with a significant increase in free Ca2+ in the cytoplasm, a decrease in ROS production, and a decline in mitochondrial potential. Both of these processes are accompanied by cytoskeleton reorganization.

Abstract
In living organisms, redox reactions play a crucial role in the progression of disorders accompanied by the overproduction of reactive oxygen and reactive chlorine species, such as hydrogen peroxide and hypochlorous acid, respectively. We demonstrate that green fluorescence graphene quantum dots (GQDs) can be employed for revealing the presence of the hypochlorous acid in aqueous solutions and cellular systems. Hypochlorous acid modifies the oxygen-containing groups of the GQD, predominantly opens epoxide ring C-O-C, forms excessive C=O bonds and damages the carbonic core of GQDs. These changes, which depend on the concentration of the hypochlorous acid and exposure time, manifest themselves in the absorbance and fluorescence spectra of the GQD, and in the fluorescence lifetime. We also show that the GQD fluorescence is not affected by hydrogen peroxide. This finding makes GQDs a promising sensing agent for selective detecting reactive chlorine species produced by neutrophils. Neutrophils actively accumulate GQDs allowing to visualize cells and to examine the redox processes via GQDs fluorescence. At high concentrations GQDs induce neutrophil activation and myeloperoxidase release, leading to the disruption of GQD structure by the produced hypochlorous acid. This makes the GQDs a biodegradable material suitable for various biomedical applications.
