Journal of the American Chemical Society
|January 15, 2026
Summary
Researchers developed artificial cell-derived vesicles (ACDVs) to deliver functional proteins directly to cell surfaces. This innovative method bypasses genetic modification for cell surface engineering and therapeutic applications.
Area of Science:
- Biotechnology
- Cell Biology
- Protein Engineering
Background:
- Cell surface proteins present challenges for functional modulation due to their complexity and undruggable nature.
- Current strategies like small-molecule inhibition have limitations in targeting these proteins effectively.
Purpose of the Study:
- To introduce a novel method for delivering functional proteins to the cell surface.
- To overcome limitations of genetic manipulation in cell surface engineering.
- To establish a programmable system for dynamic biointerfaces.
Main Methods:
- Development of artificial cell-derived vesicles (ACDVs).
- Utilizing ACDVs for direct protein delivery to the plasma membrane.
- Demonstrating the conversion of live cells into dynamic biointerfaces.
Main Results:
- Successful delivery of functional proteins onto the cell surface via ACDVs.
- Bypassing the need for genetic manipulation in protein delivery.

01:24Methods of Nuclear Reprogramming
2.1K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

2.2K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:14Introduction to Nuclear Reprogramming
2.3K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

01:24What are Membranes?
18.3K
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries...
