Abnormal modulation of cell protective systems in response to ischemic/reperfusion injury is important in the development of mouse sickle cell hepatopathy

Haematologica, 2011
Background Sickle cell disease, a genetic red cell disorder inherited in an autosomal recessive manner, occurs throughout the world. Hepatic dysfunction and liver damage may be present in sickle cell disease, but the pathogenesis of these conditions is ...

Langerhans Cells Express Inducible Nitric Oxide Synthase and Produce Nitric Oxide

Journal of Investigative Dermatology, 1996
The importance of nitric oxide (NO) in mediating macrophage functions has been demonstrated, but production of this potent gas has not been examined in Langerhans cells (LC). Using murine LC purified from epidermal cell suspensions and the recently established LC-like cell line derived from newborn BALB/c epidermis (XS-52), it was shown with reverse ...

A role for sigma factor ?(E) in Corynebacterium pseudotuberculosis resistance to nitric oxide/peroxide stress [PDF]

, 2012
Pathogenic intracellular bacteria can respond to antimicrobial mechanisms of the host cell through transient activation of stress-responsive genes by alternative sigma (?) factors of the RNA polymerase.

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

Advanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

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

Hepatology, 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 ...

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma

Advanced Science, EarlyView.
MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Molecular Signatures of HIV‐Induced Neuroinflammation and Neurodegeneration in Human Cerebral Organoids: Identification of Therapeutic Targets for NeuroHIV

Advanced Science, EarlyView.
HIV preferentially infects microglia, activating IL‐17A‐driven IFN‐γ/STAT1, CEBPB, and NF‐κB signaling that converges with cGAS‐STING and Notch–NEURL1 pathways, promoting neuroinflammation, mitochondrial dysfunction, and synaptic impairment. cART suppresses viral replication, attenuates inflammatory signaling, and at least partially restores ...
