Summary
Bionanoscale recognition influences cell fate and therapy. Octahedral coordination in 1T-MoS2 enhances cell viability and offers protection against Parkinson
Area of Science:
- Nanomaterials Science
- Biophysics
- Cell Biology
Background:
- Bionanoscale recognition is crucial for nanomaterial design and application.
- Understanding interactions between nanomaterials and biological systems is limited.
- Cell fate and therapeutic outcomes are influenced by bionanoscale recognition.
Purpose of the Study:
- To investigate the role of bionanoscale recognition in cell fate and therapy.
- To elucidate the interaction mechanisms between different molybdenum disulfide (MoS2) phases and biological molecules.
- To demonstrate the therapeutic potential of specific nanostructure coordination.
Main Methods:
- Comparative analysis of 1T-phase (octahedral coordination) and 2H-phase (triangular prism coordination) monolayer MoS2.
- Measurement of binding affinities for fibronectin and liposomes.
- Application of random forest and structural equation models to analyze cell viability data.
- Investigation of MoS2 effects on alpha-synuclein aggregation.
Main Results:
- 1T-MoS2 shows significantly higher affinity for fibronectin and liposomes compared to 2H-MoS2.
- Octahedral coordination in 1T-MoS2 enhances cell spreading, differentiation, and neurite length, improving cell viability.
- 1T-MoS2 disaggregates alpha-synuclein, reducing beta-sheets and increasing coil structures.
Conclusions:
- Bionanoscale recognition, particularly octahedral coordination, is a key determinant of cell fate and therapeutic efficacy.
- 1T-MoS2 demonstrates potential as a therapeutic agent for neurodegenerative diseases like Parkinson's disease.
- Findings provide a foundation for designing advanced biomaterials and cell therapeutics based on bionanoscale recognition principles.

4.2K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

22.1K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

01:22Diversity in Cell Signaling Responses
7.0K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

52.7K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
