Oxysterols and Their Cellular Effectors [PDF]

, 2012
Oxysterols are oxidized 27-carbon cholesterol derivatives or by-products of cholesterol biosynthesis, with a spectrum of biologic activities. Several oxysterols have cytotoxic and pro-apoptotic activities, the ability to interfere with the lateral domain

Herpes Simplex Virus Infection With Multiple Cerebral Hemorrhages: A Case Report

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Herpes simplex virus (HSV) infection may trigger rare vascular complications that lead to multiple cerebral hemorrhages. This case emphasizes considering HSV in unexplained cerebral hemorrhage among immunocompromised individuals with systemic symptoms, as timely antiviral treatment effectively improves clinical outcomes.

p90 ribosomal S6 kinases play a significant role in early gene regulation in the cardiomyocyte response to Gq protein-coupled receptor stimuli, endothelin-1 and α1-adrenergic receptor agonists [PDF]

, 2012
Extracellular signal-regulated kinases 1/2 (ERK1/2) and their substrates, p90 ribosomal S6 kinases (RSKs), phosphorylate different transcription factors, contributing differentially to transcriptomic profiles.

RORα and 25-Hydroxycholesterol Crosstalk Regulates Lipid Droplet Homeostasis in Macrophages. [PDF]

PLoS ONE, 2016
Nuclear hormone receptors have important roles in the regulation of metabolic and inflammatory pathways. The retinoid-related orphan receptor alpha (Rorα)-deficient staggerer (sg/sg) mice display several phenotypes indicative of aberrant lipid metabolism,

LL‐37 Inhibits TMPRSS2‐Mediated S2' Site Cleavage and SARS‐CoV‐2 Infection but Not Omicron Variants

Cell Proliferation, Volume 58, Issue 12, December 2025.
Cathelicidin LL‐37 inhibits SARS‐CoV‐2 by blocking the catalytic activity of TMPRSS2. The N764K mutation in the spike S2 subunit of Omicron variants confers resistance to LL‐37‐induced inhibition of TMPRSS2‐mediated S2' priming. ABSTRACT Continual evolution of SARS‐CoV‐2 spike drives the emergence of Omicron variants that show increased spreading and ...

Activation of liver X receptor plays a central role in antiviral actions of 25-hydroxycholesterol

Journal of Lipid Research, 2018
Production of 25-hydroxycholesterol (25HC), a potent inhibitor of viral infection, is catalyzed by cholesterol 25-hydroxylase (CH25H). We previously reported that 25HC induced CH25H expression in a liver X receptor (LXR)-dependent manner, implying that ...

Besnoitia besnoiti infection alters both endogenous cholesterol de novo synthesis and exogenous LDL uptake in host endothelial cells [PDF]

, 2008
Besnoitia besnoiti, an apicomplexan parasite of cattle being considered as emergent in Europe, replicates fast in host endothelial cells during acute infection and is in considerable need for energy, lipids and other building blocks for offspring ...

Extracellular LCN2 Binding to 24p3R in Astrocytes Impedes α‐Synuclein Endocytosis in Parkinson's Disease

Advanced Science, Volume 12, Issue 39, October 20, 2025.
24p3R is an astrocytic receptor for α‐Syn uptake. When LCN2 is secreted from astrocytes, it binds to its receptor 24p3R in astrocytes and this binding impedes the α‐Syn PFF binding to 24p3R. This in turn inhibits 24p3R‐mediated α‐Syn PFF uptake and reduces the clearance of extracellular α‐Syn by astrocytes, which contributes to α‐Syn spread and ...
