Can calmodulin bind to lipids of the cytosolic leaflet of plasma membranes?

Open Biology
Calmodulin (CaM) is a ubiquitous calcium-sensitive messenger in eukaryotic cells. It was previously shown that CaM possesses an affinity for diverse lipid moieties, including those found on CaM-binding proteins. These facts, together with our observation

Biomimetic Hydrogel System Targeting S100A8 Centered Neuroimmune Crosstalk and Hypoxia Induced Neuronal Injury

Advanced Science, EarlyView.
A biomimetic hydrogel (HPC@Gel) was developed for traumatic brain injury repair by combining oxygen‐carrying hemoglobin nanoparticles and anti‐inflammatory carbon quantum dots within a brain‐like matrix. The system alleviated hypoxia, reduced harmful neuroimmune signaling, protected neurons, supported neural regeneration, and improved neurological and ...

Inner Mitochondrial Membrane Disruption Links Apoptotic and Agonist-Initiated Phosphatidylserine Externalization in Platelets [PDF]

, 2017
Objective— Phosphatidylserine exposure mediates platelet procoagulant function and regulates platelet life span. Apoptotic, necrotic, and integrin-mediated mechanisms have been implicated as intracellular determinants of platelet

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Triggering of Programmed Erythrocyte Death by Alantolactone

Toxins, 2014
The sesquiterpene alantolactone counteracts malignancy, an effect at least in part due to stimulation of suicidal death or apoptosis of tumor cells.

Intratumoral Hypoxia Triggers Mitochondrial BHLHE40 ROS Sensing Pathway to Promote Radioresistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Hypoxia triggers a dual mechanism for BHLHE40 upregulation: reactive oxygen species (ROS)‐dependent post‐translational modification and hypoxia‐inducible factor (HIF)‐dependent transcriptional activation. Under hypoxic conditions, mitochondrial BHLHE40 accumulates and senses ROS via cysteine thiol oxidation and disulfide‐linked homodimer formation ...

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

Advanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

Autoantibodies to Extracellular Erythrocyte Band 3 Epitopes Are Associated With Anemia in Plasmodium vivax Infection

American Journal of Hematology, EarlyView.
ABSTRACT Plasmodium vivax‐associated anemia is a multifactorial clinical outcome, in which the destruction of uninfected red blood cells (uRBCs) plays a major role in disease development and severity. Here, we identified autoantibody targets within the extracellular loops of Band 3 (B3), a major erythrocyte transmembrane protein.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are
