Infectious Disease Exosome Research Solution

Online Inquiry

In the past decades, knowledge about exosomes has been developed in various directions, especially regarding pathogenic infections. More recently, quantitative analysis of samples by multi-omics technologies has allowed in-depth characterization of exosomal proteins, lipids, RNA and other metabolites. An in-depth understanding of the content of these vesicles can facilitate their therapeutic application. Moreover, since exosomes are detected in almost all biological fluids, components of pathogenic or host origin can be identified in liquid biopsies, making them suitable for diagnostic and prognostic purposes. Creative Proteomics has been working with exosome research and analysis for years. Our reliable and customized services can support infectious disease exosome research, including exosome composition and function during viral, bacterial, fungal, and protozoan infections, facilitating the study of exosomes in host defense or pathogen transmission.

The role of exosomes in pathogen infections

Exosomes are extracellular vesicles (EVs) derived from endosomal compartments and can be released by eukaryotic as well as eukaryotes as well as prokaryotes. These EVs have a variety of bioactive molecules, the number and type of which depend on the origin and cellular state. The exosomes are then internalized by the recipient cells to deliver their contents, thus facilitating cell-cell communication in health and disease. During the process of infection, exosomes have a dual role. On one hand, these vesicles can deliver pathogen-associated molecules that facilitate the continuation and enhancement of infection processes, and on the other hand, they can protect the host by activating the immune response and reducing pathogen transmission. In both cases, exosomes enable a possible link between host cells or between pathogens and host cells.

  • Exosomes can accelerate the process of infection

-Mediating further infection through the transmission of pathogen-related molecules

-Exosomes from parasites can be involved in virulence and cytotoxicity

-Participating in the immune escape of pathogens

-Promoting immune cell apoptosis inhibiting immune responses

  • Exosomes inhibit the process of infection

-Inhibiting pathogen proliferation and transmission directly

-Inhibiting infection by stimulating immune responses, involving B, T cells, NK-cells, and monocyte-macrophage.
