Entamoeba-derived Exosome Research & Application
Overview Workflow Insights Advantages Testimonials FAQs
Overview
Exosomes derived from Entamoeba histolytica, the causative agent of amoebiasis, have become an increasingly important focus in parasitology research. These exosomes are key mediators of inter-parasite communication and regulation of host immune responses. Recent studies suggest that Entamoeba-derived exosomes can influence the immune system by modulating host immune cells, such as neutrophils, while also facilitating parasite-to-parasite communication. The cargo within these exosomes, including small RNA molecules and proteins like Gal/GalNAc lectin and calreticulin, is critical in facilitating these interactions and enhancing the immune-modulating abilities of the exosomes. Understanding the mechanisms by which Entamoeba exosomes regulate immune responses and parasite behavior offers valuable insights into the parasite's pathogenesis and suggests novel strategies for parasite management.
Creative Biolabs provides specialized isolation and profiling services for Entamoeba-derived exosomes, enabling researchers to delve deeper into these complex biological processes. Our team can assist in dissecting how these exosomes contribute to immune modulation and inter-parasitic communication, paving the way for further investigations in parasitology.
Isolation Workflow for Entamoeba-Derived Exosomes
At Creative Biolabs, we follow a meticulous process for isolating Entamoeba exosomes while offering additional optional services for detailed characterization. Our standard protocol ensures high-purity exosomes, which are essential for downstream analyses such as proteomic profiling and functional assays.
Standard Exosome Isolation Workflow:
-
Culture Preparation:
-
Axenically culture Entamoeba histolytica trophozoites under standard conditions to ensure optimal parasite growth.
-
Once in mid-log phase, transfer trophozoites into encystation media to stimulate cyst formation.
-
Medium Collection:
-
After culturing, collect Entamoeba culture media and centrifuge at low speed to remove larger cellular debris.
-
Filter the supernatant to clear any remaining contaminants.
-
Exosome Enrichment:
-
Sediment exosomes from the supernatant using specific chemical reagents and centrifuge again to concentrate exosome particles.
-
The final exosome precipitate is collected for subsequent analysis.
-
Purification and Concentration:
-
Purify the exosome fraction using high-speed ultracentrifugation.
-
Further refinement may include sucrose gradient centrifugation to ensure high-quality exosome preparation.
Optional Additional Services:
-
Characterization (optional):
-
Advanced techniques, such as electron microscopy (EM), nanoparticle tracking analysis (NTA), and Western blotting, for size distribution and marker identification.
-
Molecular Profiling (optional):
-
Small RNA sequencing, proteomic profiling, and lipidomic analysis to deeply explore the composition of Entamoeba-derived exosomes.
-
Functional Studies (optional):
-
Immune modulation assays, such as ROS production or NETosis quantification, to assess the functional impact of exosome cargo on host immune cells.

|
Findings and Insights
|
|
Protein Cargo
|
Proteomic analysis showed that Entamoeba-derived exosomes are enriched in Gal/GalNAc lectin proteins while being depleted of cytoskeletal proteins, confirming selective protein loading.
|
|
Proteomic Profiling
|
Mass spectrometry revealed that Entamoeba exosomes contain proteins involved in vesicle formation, molecular binding, and intracellular signaling, with little association with plasma membrane or other endosomal compartments.
|
|
Small RNA Profiling
|
PAGE assays identified 27-nt small RNAs, predominantly tRNA fragments, in exosomes. These small RNAs were resistant to RNase A digestion, suggesting they play a role in RNA interference (RNAi).
|
|
Exosome Function in Encystation
|
Functional assays demonstrated that exosomes from encysting Entamoeba promoted the encystation of other parasites, while exosomes from trophozoites hindered encystation, highlighting inter-parasite communication.
|
|
ROS Regulation in Neutrophils
|
Co-culture exosomes from Entamoeba trophozoites and neutrophils induced higher ROS production, suggesting an immune-modulating role.
|
|
Impact on NETosis
|
Exosomes from Entamoeba trophozoites suppressed neutrophil respiratory burst and NETosis, demonstrating an immune evasion strategy employed by the parasite.
