The Use of Vesicles from Cow Milk for Oral Drug Delivery
Tom Anchordoquy, Professor, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, United States of America

Many pharmaceuticals must be administered intravenously due to their poor oral bioavailability.  In addition to issues associated with sterility and inconvenience, the cost of repeated infusion over a six-week course of therapy costs the healthcare system tens of billions of dollars per year.  Attempts to improve oral bioavailability have traditionally focused on enhancing drug solubility and membrane permeability, and the use of synthetic nanoparticles has also been investigated.  As an alternative strategy, some reports have clearly demonstrated that exosomes from cow milk are absorbed from the gastrointestinal tract in humans, and could potentially be used for oral delivery of drugs that are traditionally administered intravenously.  Our results demonstrate that milk exosomes are absorbed from the gut as intact particles that can be modified with ligands to promote retention in target tissues.

Optimizing Dendritic Cell-Derived Exosomes For Cancer Immunotherapy
Susanne Gabrielsson, Professor, Division of Immunology and Allergy, Department of Medicine Solna, Karolinska Institutet, Sweden

Peptide loaded exosomes are promising cancer treatment vehicles, however, low T cell responses in human clinical trials indicate a need to further understand exosome-induced immunity. We previously demonstrated that antigen-loaded exosomes carry whole protein antigens and require B cells for induction of antigen-specific T cells. I will discuss our latest data where we investigated the need for different immune related molecules on exosomes to induce T cell responses and tumor rejection in the B16 mouse melanoma model. Our data demonstrate ways to increase the feasibility of exosome-based therapeutic approaches in cancer.

Exosomes and Viral Infections: Struggles of the Host Cell with the Intracellular Pathogen
Fatah Kashanchi, Professor, George Mason University, United States of America

In order to perform normal functions, cells release various types of vesicles, such as exosomes and microvesicles (MVs) derived from endosomes and the plasma membrane. These extracellular vesicles (EVs) play a significant role in intercellular communication by serving as a carrier for the transfer of membrane and cytosolic proteins, lipids, and RNA between cells. In recent years, using state of the art technologies such as RNA seq, RPMA, and single cell omics, we have found that virally infected cells including HIV, HTLV, Rift Valley Fever, VEEV, Zika and Ebola virus secret exosomes that contain biomarker of infections. These markers include viral RNA, viral proteins and a range of unique cellular proteins that are released from infected cells. EVs were characterized using electron microscopy, nanoparticle tracking analysis (NTA), and common structural and functional proteins, such as Rab GTPase, SNAREs, annexins, Alix, Tsg101, flotillin and tetraspanins. These exosomes can be found in bodily fluids including urine, saliva, CSF, and blood. Interestingly, these exosomes can be detected during most inhibitory treatments (i.e. IFN, cART) indicating that infected cells may be present and active in tissues reservoirs (i.e. CNS, Lymph nodes). They also contain the usual viral proteins and RNAs and may be part of an early overexpression by these viruses to favor virus gene expression, assembly, and budding.  Therefore, exosomes from infected cells pose a superior predictor of host response biomarker of infection since they contain and protect the viral biomarkers in various bodily fluids. In recent years, the diverse biological cargo contained within certain uninfected stem cell EVs (i.e., iPSC or MSC) are used for repair purposes.  In a series of recent studies using large scale purification methods via tangential flow filtration (TFF), we have isolated iPSCs and MSCs EVs which significantly enhance the processes of cellular migration and angiogenesis in healthy recipient cells.  In models of induced cellular damage (i.e., irradiation or infections), these EVs had the ability to rescue viability in multiple 2D and 3D cultures. Interestingly, there seems to be a “dual” mode of action, where non-coding RNAs activate innate immune molecules followed by presence of cytokines for activation and repair.  Collectively, these results from past few years demonstrate the potential of EVs as diagnostic markers of infection, and stem cell EVs as a “holistic” therapeutic approach to reverse or to reduce cellular damage.

Development of Therapeutic Exosomes: Principles and Applications
Chulhee Choi, Professor and Chair, BioMedical Imaging Center, Korea Advanced Institute of Science and Technology (KAIST), President, ILIAS Biologics Incorporated, Korea South

Our group has recently developed an opto-genetically engineered exosome system, named "exosomes for protein loading via optically reversible protein–protein interaction” (EXPLOR) that can deliver soluble proteins into the cytosol of target cells via controlled, reversible protein–protein interactions (PPI). By integrating a reversible PPI module controlled by specific wavelength of light with the endogenous process of exosome biogenesis, cargo proteins of our interest can be loaded into newly generated exosomes. Protein-loaded exosomes were shown to significantly increase intracellular levels of cargo proteins and their function in recipient cells in both a time- and dose-dependent manner. In this presentation, I will introduce the basic principles of EXPLOR technology and follow-up studies for therapeutic applications.

A Multi-Dimensional Approach to EV Flow Cytometry
Andries Zijlstra, Associate Professor of Pathology, Microbiology and Immunology, Vanderbilt University Medical Center and Vanderbilt Ingram Cancer Center, United States of America

Flow cytometry has proven to be very promising method for Single-EV analysis. Unfortunately, the heterogeneity of EV populations prevents the application of the single-particle classification strategy derived from conventional flow cytometry of intact cells fails in our attempts to resolve distinct classes of EVs. In simple terms, the small size of most EVs prevents the incorporation of all protein markers that define a uniform class of EVs. Consequently, EVs generated through the same biogenesis pathway from the same donor cells, could contain vastly different cargo. Conversely, restricting EV classification only to a size range is equally limiting. To improve EV sub-classification and enable the identification of biologically-significant alterations in EV populations in response to alterations in physiological or pathological states of the donor cell/tissue, we have developed a multi-dimensional approach to EV flow cytometry that attempts to cluster EVs into subpopulations on the basis of many, rather than single parameters.

Lorraine O’DriscollKeynote Presentation

The Hopes and Hypes of EV-based Diagnostics, Therapeutics and Delivery in Cancer
Lorraine O’Driscoll, Professor in Pharmacology, Trinity College Dublin, Ireland

Increasing evidence indicates that substantial "cargos of information" involved in cell-to-cell communication are transported out of cells and into body fluids via membrane-surrounded vesicles that are then termed extracellular vesicles (EVs). EVs content seems to include proteins, RNAs and DNA. These -collectively termed extracellular vesicles (EVs)- released from cells were originally considered as junk but are now considered to be mini-maps of their cells of origin.

Some EVs are released from healthy cells and are associated with a range of physiological functions. In cancer, studies of cell lines, animal models and serum or plasma from patients and healthy individuals have advocated EVs in a positive light as minimally-invasive diagnostics and predictive biomarkers, based on relative EV quantitative and/or contents.

High-Throughput Engineering Exosomes For Precision Immunotherapy
Mei He, Assistant Professor, University of Kansas, United States of America

Studying extracellular vesicles (EV), particularly exosomes, is holding great promise. With intrinsic molecular payload and biodegradability, molecular engineering of exosomes opens new avenues for mediating cellular responses and developing novel nano-delivery systems in precision immunotherapy. We will report several novel approaches including microfluidic technology and nanotechnology developed in our research group for engineering exosomes as nanodelivery system employed in advancing precision immunotherapy.
