Summary
Researchers developed DNA-encoded artificial receptors and ligands to monitor cell membrane redistribution, enabling high-fidelity cell classification for diagnostic purposes.
Area of Science:
- Biochemistry
- Molecular Biology

Background:
- Cell membrane molecule redistribution is cell-type dependent but not used for classification.
- Existing methods lack the ability to exploit membrane dynamics for cell typing.
Purpose of the Study:
- To develop a DNA-encoded system for monitoring cell membrane redistribution.
- To enable cell classification and diagnosis based on membrane dynamics.
Main Methods:
- Designed DNA-encoded artificial receptors (cholesterol-modified ssDNA) and ligands (tetrahedral DNA framework nanostructures).
- Utilized orthogonal DNA-encoded receptor-ligand interactions to mimic natural cell processes.
- Resolved membrane redistribution dynamics via dual-color fluorescent patterns in single images.
Main Results:
- Successfully monitored cell membrane redistribution using the DNA-encoded system.
- Achieved high-fidelity classification of cell lines based on observed membrane dynamics.
- Demonstrated the potential of the method for cell typing and diagnosis.
Conclusions:
- The DNA-encoded receptor-ligand system effectively monitors cell membrane redistribution.
- This novel approach offers a promising tool for cell classification and medical diagnosis.
- The method mimics natural receptor-ligand dynamics for accurate cell analysis.

01:28Types of Receptors: Cell Surface Receptors
25.9K
Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored (integral) proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal. Ligands that interact with cell-surface receptors do not have to enter the cell that they affect. Cell-surface receptors are also called cell-specific proteins or markers because they are...

01:26Signal Transduction: Overview
11.0K
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.

01:32Types of Signaling Molecules
12.5K
In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...

53.6K
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.

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
