Introduction: Exploring Vesicle Complexity in Catharanthus roseus

Catharanthus roseus, widely known as Madagascar periwinkle, has long been valued in botanical science for its secondary metabolites. More recently, its extracellular vesicles—specifically exosomes—have emerged as a new focal point for plant-based nanovesicle research. At Creative Biolabs, we offer a comprehensive platform for the investigation and application of Catharanthus roseus-derived exosomes (CRDEs), aimed at academic and industrial researchers focused on foundational exosome biology.

CRDEs are attracting interest due to their structural resilience, molecular richness, and potential for scale-up. With specialized profiling techniques and deep domain expertise, Creative Biolabs supports scientific exploration across characterization, biosynthesis pathways, immune modulation, and vesicle engineering. Our work on CRDEs advances the broader understanding of plant-derived extracellular vesicles while reinforcing our reputation for scientific rigor and custom project support.

Our Focus: What Makes Catharanthus roseus-Derived Vesicles Unique

CRDEs possess several remarkable biological and physical features:

Exceptional Stability: CRDEs resist enzymatic degradation (nucleases and proteases) and maintain membrane integrity even in acidic or basic environments.
Distinct Lipid Profile: Ether phospholipids dominate CRDE lipidomics, potentially contributing to vesicle longevity and bioactivity.
Immune Modulation: In vitro data suggest CRDEs activate the TNF-α/NF-κB/PU.1 axis in immune cells, stimulating cytokine production and lymphocyte proliferation.
Organ-Specific Distribution: CRDEs localize to immune organs post intraperitoneal injection and show survivability in the digestive tract upon oral administration.

Our characterization pipeline at Creative Biolabs has confirmed the unique proteomic signature of CRDEs, including enrichment in polycystin-associated proteins, which may indicate their multivesicular body (MVB) origin—a noteworthy insight for plant exosome studies.
