Mechanistic Disruption of the TREM2-DAP12 Transmembrane Complex by Alzheimer's Disease Mutations: A Multiscale Simulation Study.

Journal of chemical information and modeling
Triggering receptor expressed on myeloid cell 2 (TREM2) is an immunomodulatory receptor that plays a critical role in microglial activation through its association with the adaptor protein DNAX-activation protein 12 (DAP12). Variants in TREM2 have be...

Electromechanically induced membrane restructuring enables learning and memory.

Proceedings of the National Academy of Sciences of the United States of America
Human neural networks of interconnected neurons have evolved to be remarkably efficient and are capable of learning and memory through the brain's synaptic plasticity, including short-term plasticity (STP), and long-term potentiation (LTP) and depres...

Analysis of disruptive action of electrical current on cell membrane integrity and modelling its antimicrobial activity.

Archives of microbiology
It is essential to eliminate harmful microbes from vital aspects of our lives, including dental instruments and other healthcare devices, cosmetics, foods, and products that come into contact with them. Electrical stimulation (ES) has been proposed t...

Neuronal Membrane-Functionalized Biohybrid Microrobots for Active Decontamination of Neurotoxins in Aqueous Environments.

ACS nano
The emergence of biohybrid microrobots offers a promising platform for environmental remediation; however, their potential for neurotoxin decontamination remains largely unexplored. Neurotoxins, such as tetrodotoxin (TTX), pose acute threats to aquat...

Nondisruptive inducible labeling of ER-membrane contact sites using the Lamin B receptor.

PLoS biology
Membrane contact sites (MCSs) are areas of close proximity between organelles that allow the exchange of material, among other roles. The endoplasmic reticulum (ER) has MCSs with a variety of organelles in the cell. MCSs are dynamic, responding to ch...

Recent advances of engineering cell membranes for nanomedicine delivery across the blood-brain barrier.

Journal of nanobiotechnology
The blood-brain barrier (BBB) poses a major challenge to the effective delivery of therapeutic agents for the treatment of central nervous system (CNS) disorders. The integration of cell membrane engineering with nanotechnology has recently enabled t...

Recognition of Specific PIP2-subtype Composition Triggers the Allosteric Control Mechanism for Selective Membrane Targeting of Cargo Loading and Release Functions of the Intracellular Sterol Transporter StarD4.

Journal of molecular biology
We present a comprehensive, quantitative model of the allosteric molecular mechanisms of selective cholesterol (CHL) uptake and delivery by the StarD4 protein - an intracellular cholesterol trafficking protein that facilitates the crucial non-vesicul...

Interpretable Multiscale Convolutional Neural Network for Classification and Feature Visualization of Weak Raman Spectra of Biomolecules at Cell Membranes.

ACS sensors
Raman spectroscopy in biological applications faces challenges due to complex spectra, characterized by peaks of varying widths and significant biological background noise. Convolutional neural networks (CNNs) are widely used for spectrum classificat...

Translational nanorobotics breaking through biological membranes.

Chemical Society reviews
In the dynamic realm of translational nanorobotics, the endeavor to develop nanorobots carrying therapeutics in rational applications necessitates a profound understanding of the biological landscape of the human body and its complexity. Within this...

PREPRINT Machine Learning for the Sensitivity Analysis of a Model of the Cellular Uptake of Nanoparticles for the Treatment of Cancer.

International journal for numerical methods in biomedical engineering
Experimental studies on the cellular uptake of nanoparticles (NPs), useful for the investigation of NP-based drug delivery systems, are often difficult to interpret due to the large number of parameters that can contribute to the phenomenon. It is th...
