2025
The therapeutic application of extracellular vesicles (EVs) has the potential to revolutionize cancer treatment and drug delivery. Chimeric antigen receptor (CAR) cell-derived EVs (CAR-EVs) isolated using ion-exchange chromatography exhibit increased cargo capacity, significantly enhancing their functional efficacy. This study further characterizes CAR-EVs to elucidate their biological activity and therapeutic potential.

2025
The video outlines a process for creating genetically modified CAR T cells through the CRISPR-Cas9 System. Infecting T cells with CRISPR and CAR lentiviruses results in modifications to the target gene and the synthesis of a chimeric antigen receptor or CAR, ultimately leading to the formation of genetically modified CAR T cells.

2025
This video demonstrates a technique for generating antigen-specific chimeric antigen receptor (CAR) T cells through retroviral transduction. Activated murine CD8+ T cells are added to a microwell plate coated with recombinant fibronectin fragments. Retroviral vectors containing transgenic RNA encoding an antigen-specific chimeric antigen receptor (CAR) are then introduced, and the plate is centrifuged to facilitate transduction. After incubation, the transduced cells express antigen-specific...

2025
This video demonstrates an in vitro assay evaluating the cytotoxic effects of CAR T cells on 3D tumor spheroids expressing fluorescent proteins. This assessment utilizes the Annexin V red fluorescent probe, which binds to exposed phosphatidylserine residues on the outer leaflet of apoptotic cancer cells after interactions with CAR T cells. The red fluorescence emitted by the probe aids in distinguishing these cells from healthy ones emitting green fluorescence.

FM Dyes in Vesicle Recycling
0 Views •
2023
FM dyes are a class of fluorescent molecules that has found important use in studying the vesicle recycling process. By virtue of a chemical structure, these molecules can insert themselves into the outer leaflet of phospholipid bilayer membranes. After membrane insertion, they are internalized into the cell via endocytosed vesicles, and released when these vesicles recycle back to the membrane. Since, these dyes fluoresce strongly in the hydrophobic environment within membranes and weakly in...
FAQs
The CAR-binding domain provides the targeting step: it attaches to EGFR on a cell surface, linking vesicle contact to receptor status. This specificity allows investigators to examine interactions with EGFR-bearing cells rather than treating vesicle association as nonspecific. In experiments, EGFR recognition therefore becomes a key variable when comparing targeted interaction or delivery behavior.
The vesicle membrane can help protect associated molecular cargo during transport while the displayed CAR directs interaction toward EGFR-bearing cells. These two functions connect cargo handling with surface recognition, allowing researchers to study whether targeted contact improves delivery selectivity. Cargo release remains a separate performance consideration because transport alone does not establish that the molecular contents reach their intended site.
Performance depends on several linked properties: how vesicles are produced, whether CARs become incorporated into their membranes, how effectively the CAR recognizes EGFR, where the vesicles distribute, and whether cargo is released. Evaluating these variables separately helps distinguish problems in vesicle generation, targeting, transport, or release instead of attributing every outcome to EGFR binding.
A study can follow the sequence reflected in their design: produce the vesicles, examine CAR incorporation, assess recognition of EGFR-bearing cells, track biodistribution, and evaluate cargo release. This workflow connects construction with biological performance. It also helps researchers determine whether a vesicle platform shows the intended progression from molecular targeting to transport and usable delivery.
They can serve as a platform for studying receptor-specific communication in biology. By focusing interactions on EGFR-bearing cells, researchers can investigate how a displayed recognition element influences vesicle association and distribution. Measurements of biodistribution and release add context about what happens after contact, supporting analysis of both cell interaction and delivery behavior.
Their relevance comes from combining targeted cell interaction with a vesicle-based delivery platform rather than relying exclusively on engineered immune cells. In cancer research, this supports efforts to improve the selectivity of therapeutic cargo delivery and to explore cell-free alternatives. The approach remains dependent on effective EGFR recognition, appropriate distribution, and successful cargo release.
