Dormant 5-lipoxygenase in inflammatory macrophages is triggered by exogenous arachidonic acid [PDF]

Scientific Reports, 2017
AbstractThe differentiation of resident tissue macrophages from embryonic precursors and that of inflammatory macrophages from bone marrow cells leads to macrophage heterogeneity. Further plasticity is displayed through their ability to be polarized as subtypes M1 and M2 in a cell culture microenvironment. However, the detailed regulation of eicosanoid

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

Advanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

ATP allosterically activates the human 5-lipoxygenase molecular mechanism of arachidonic acid and 5(S)-hydroperoxy-6(E),8(Z),11(Z),14(Z)-eicosatetraenoic acid. [PDF]

, 2014
5-Lipoxygenase (5-LOX) reacts with arachidonic acid (AA) to first generate 5(S)-hydroperoxy-6(E),8(Z),11(Z),14(Z)-eicosatetraenoic acid [5(S)-HpETE] and then an epoxide from 5(S)-HpETE to form leukotriene A4, from a single polyunsaturated fatty acid ...

CRISPR Enabled Precision Oncology: From Gene Editing to Tumor Microenvironment Remodeling

Med Research, EarlyView.
CRISPR technology has progressed from a prokaryotic immune system to a diverse suite of editing platforms, including Cas nucleases, base and prime editors, and RNA‐targeting enzymes. These advances enable precise genomic and epigenomic interventions, high‐throughput functional screening, and immune engineering.

Update on Non‐Biological and RNA‐Based Therapeutics in Chronic Inflammatory Diseases: Precision Medicine Through Small Molecules

Allergy, EarlyView.
ABSTRACT In the last decades, critical advancements in research technology and knowledge on disease mechanisms steered therapeutic approaches for chronic inflammatory diseases towards unprecedented target specificity. For allergic and chronic lung diseases, biologic drugs pioneered this goal, acquiring on the way—through the clinical use of monoclonal ...

RNA‐Binding Proteins and Ferroptosis in Cancer: Mechanism and Therapeutic Implications

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ferroptosis critically influences cancer cell fate and represents a promising therapeutic strategy. Emerging evidence identifies RNA‐binding proteins (RBPs) as key post‐transcriptional regulators of ferroptosis. The figure summarizes ferroptosis‐related RBPs across cancers: blue RBPs act as tumor suppressors by promoting ferroptosis, whereas red RBPs ...

Local and global modes of drug action in biochemical networks [PDF]

, 2008
It becomes increasingly accepted that a shift is needed from the traditional target-based approach of drug development to an integrated perspective of drug action in biochemical systems. We here present an integrative analysis of the interactions between

12‐HETE is an Endogenous Modulator of BLT2 Triggering Vascular Degeneration, Dissection, and Rupture

Advanced Science, Volume 13, Issue 5, 27 January 2026.
In thoracic aortic dissection (TAD), elevated levels of the arachidonic acid metabolite 12‐HETE, produced by macrophage‐specific 12/15‐lipoxygenase (12/15‐LOX), bind to the BLT2 receptor on vascular cells. This activates the NOX‐1/ROS/NF‐κB signaling pathway, leading to IL‐6 release.

The Progress of Ferroptosis of Immune Cells in the Tumor Microenvironment and Its Impact on Tumorigenesis and Development

Immunity, Inflammation and Disease, Volume 14, Issue 1, January 2026.
The interplay between ferroptosis and the tumor immune microenvironment significantly influences the outcome of cancer immunotherapy. Inducing ferroptosis in tumor cells and immunosuppressive cells, while preventing ferroptosis in effector immune cells, emerges as a promising strategy to enhance the efficacy of immunotherapy. This review highlights the
