Neutrophil activation and neutrophil extracellular traps (NETs) in COVID‐19 ARDS and immunothrombosis

open access: yesEuropean Journal of Immunology, Volume 53, Issue 1, January 2023., 2023
Neutrophils play a role in the immunopathology SARS‐CoV‐2 infection by triggering the formation of NETs, producing cytokines including interleukin‐8 (CXCL8), and mediating the recruitment of other immune cells to regulate inflammation, which can lead to ARDS.

Portosystemic hepatic encephalopathy model shows reversal learning impairment and dysfunction of neural activity in the prefrontal cortex and regions involved in motivated behavior [PDF]

open access: yesJournal of Clinical Neuroscience (2011)18(5):690-4, 2011
Hepatic encephalopathy is a neurological complication that affects attention and memory. Experimental animal models have been used to study hepatic Encephalopathy, the most frequent being the portacaval shunt. In order to determine learning impairment and brain functional alterations in this model, we assessed reversal learning and neural metabolic ...

NADPH Oxidase and Cardiac Failure [PDF]

open access: yesJournal of Cardiovascular Translational Research, 2010
Increases in oxidative stress in the heart play an important role in mediating hypertrophy, apoptosis, fibrosis, mitochondrial dysfunction, and the consequent development of heart failure. Although it has been widely believed that electron leakage from the mitochondrial electron transport chain is the primary source of oxidative stress in the failing ...

Extended Linear Response for Bioanalytical Applications Using Multiple Enzymes [PDF]

open access: yesAnalyt. Chem. 85, 2027-2031 (2013), 2013
We develop a framework for optimizing a novel approach to extending the linear range of bioanalytical systems and biosensors by utilizing two enzymes with different kinetic responses to the input chemical as their substrate. Data for the flow-injection amperometric system devised for detection of lysine based on the function of L-Lysine-alpha-Oxidase ...

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis

open access: yesHepatology, EarlyView., 2022
EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

NADPH Oxidases: Progress and Opportunities [PDF]

open access: yesAntioxidants & Redox Signaling, 2014
From the initial discovery in 1999 that NADPH oxidases comprise a family of enzymes to our current focus on drug development to treat multiple pathologies related to this enzyme family, progress has been swift and impressive. We have expanded our understanding of the extent of the family, the basic enzymatic biochemistry, the multiple cellular ...

D2HGDH Deficiency Regulates Seizures through GSH/Prdx6/ROS‐Mediated Excitatory Synaptic Activity

open access: yesAdvanced Science, EarlyView.
Downregulating D‐2‐hydroxyglutarate dehydrogenase (D2HGDH) increases epilepsy susceptibility by altering reactive oxygen species (ROS) levels and synaptic function, contributing to oxidative stress in neurons. The acid calcium‐independent phospholipase A2 (aiPLA2) inhibitor MJ33 restores glutathione reduced/glutathione oxidized balance, reducing ROS ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Structures of human dual oxidase 1 complex in low-calcium and high-calcium states

open access: yesNature Communications, 2021
Dual oxidases (DUOXs), assembled from the catalytic DUOX and the auxiliary DUOXA subunits, produce hydrogen peroxide by transferring electrons from intracellular NADPH to extracellular oxygen in a calcium-activated manner. Here authors report the cryo-EM
