Molecular and Functional Cargo of Plasma-Derived Exosomes in Patients with Hereditary Hemorrhagic Telangiectasia. J Clin Med 2024; 13:5430. [PMID: 39336917 PMCID: PMC11432581 DOI: 10.3390/jcm13185430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2024] [Revised: 09/09/2024] [Accepted: 09/11/2024] [Indexed: 09/30/2024] Open
Abstract
Background: Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder leading to frequent bleeding in several organs. As HHT diagnosis is demanding and depends on clinical criteria, liquid biopsy would be beneficial. Exosomes from biofluids are nano-sized vesicles for intercellular communication. Their cargo and characteristics represent biomarkers for many diseases. Here, exosomes of HHT patients were examined regarding their biosignature. Methods: Exosomes were isolated from the plasma of 20 HHT patients and 17 healthy donors (HDs). The total exosomal protein was quantified, and specific proteins were analyzed using Western blot and antibody arrays. Human umbilical vein endothelial cells (HUVECs) co-incubated with exosomes were functionally examined via immunofluorescence, proliferation, and scratch assay. Results: The levels of the angiogenesis-regulating protein Thrombospondin-1 were significantly higher in HHT compared to HD exosomes. Among HHT, but not HD exosomes, a negative correlation between total exosomal protein and soluble Endoglin (sENG) levels was found. Other exosomal proteins (ALK1, ALK5) and the particle concentration significantly correlated with disease severity parameters (total consultations/interventions, epistaxis severity score) in HHT patients. Functionally, HUVECs were able to internalize both HD and HHT exosomes, inducing a similar change in the F-Actin structure and a reduction in migration and proliferation. Conclusions: This study provided first insights into the protein cargo and function of HHT-derived exosomes. The data indicate changes in sENG secretion via exosomes and reveal exosomal Thrombospondin-1 as a potential biomarker for HHT. Several exosomal characteristics were pointed out as potential liquid biomarkers for disease severity, revealing a possible new way of diagnosis and prognosis of HHT.

Abstract
Exosomes are a group of vesicles that package and transport DNA, RNA, proteins, and lipids to recipient cells. They can be derived from blood, saliva, urine, and/or other biological tissues. Their impact on several diseases, such as neurodegenerative, autoimmune, and ocular diseases, have been reported, but not fully unraveled. The exosomes that are derived from saliva are less studied, but offer significant advantages over exosomes from other sources, due to their accessibility and ease of collection. Thus, their role in the pathophysiology of diseases is largely unknown. In the context of ocular diseases, salivary exosomes have been under-utilized, thus creating an enormous gap in the literature. The current review discusses the state of exosomes research on systemic and ocular diseases and highlights the role and potential of salivary exosomes as future ocular therapeutic vehicles.

Abstract
Oral cancers occurring in different subsites can have distinct etiologies' and are a significant problem worldwide. In general, the incidence of oral cancers has declined over the last decade due to improvements in modifiable risk factors (tobacco and alcohol consumption). However, recent data suggest that the incidence of squamous cell carcinomas in the oral tongue and oropharynx are increasing. Human papilloma virus (HPV) is an important risk factor for oropharyngeal cancer and is associated with better treatment responses when compared with HPV-unrelated oropharyngeal cancer. Regardless of the subsite, there are no clinically available biomarkers for the early detection of these cancers and many are detected at an advanced stage and are associated with poor 5-year survival rates. Tumor tissue and serial needle biopsies are used to diagnose and prognosticate oral cancers but have important limitations. Besides being invasive and physically painful, these types of biopsies offer a limited view of a complex tumor due to inter- and intra-tumoral heterogeneity and a dynamic tumor microenvironment. Liquid biopsies offer a promising and alternative way to measure disease in real-time. Extracellular vesicles (EVs) are small particles that are secreted by all cells types and can be readily isolated from a wide range of biofluids. EVs are structurally stable and can horizontally transfer bioactive molecules to distant sites throughout the body in concentrated forms that exceed what can be delivered in a soluble format. As EVs represent their cell of origin, biofluid derived EVs are heterogeneous and are comprised of a complex repertoire of host- and cancer-derived particles. This review article has focused on studies that have used transcriptomics and proteomics to explore the function and clinical significance of EVs in oral cavity and oropharyngeal cancers.

Abstract
BACKGROUND Swallowing is one of the most complex movement patterns. The integrity of the epithelial lining is essential. OBJECTIVE Which surgical techniques were developed at the beginnings of modern surgery and what methods are now available to maintain/reconstitute the integrity of the swallowing apparatus? MATERIALS AND METHODS This study comprises a selective literature search in early operation manuals and online archives, with incorporation of the authors' own experience. RESULTS Up until the 1950s, only very limited techniques were available to reconstruct the epithelial lining. Microvascular reanastomosed grafts were the game changer for reconstructive surgery, enabling reconstitution of the swallowing apparatus in primary surgery but also in challenging secondary interventions after insufficient or complicated primary therapy. CONCLUSION The need for anatomical and functional rehabilitation by reconstructive surgery is as pertinent as ever. Particularly in the oncological context, improved early detection and novel local treatment modalities could minimize treatment-associated damage to swallowing.

Abstract
BACKGROUND Clinical application of immune checkpoint inhibitors (ICI), whether as monotherapy or in combination with established methods, is revolutionizing treatment of head and neck cancer. However, this change in therapeutic concepts requires reevaluation and further development of predictive and prognostic markers, since the survival rates for advanced and particularly human papillomavirus (HPV)-negative disease remain poor. MATERIALS AND METHODS A selective literature review was performed in PubMed. Literature found with the keywords "cytodiagnostics, circulating tumor cells, liquid biopsy, cfDNA, exosomes" in combination with "head and neck cancer" and/or "immune checkpoint inhibitor therapy" published until March 2020 was included. The articles were selected for their relevance for the current study by the authors. RESULTS This work provides a review of the current literature and indicates possible applications in the field of head and neck cancers. Liquid biopsy refers to the analysis of circulating tumor cells or of tumor genetic material in body fluids. This minimally invasive analysis can support therapeutic decisions and enable a personalized approach to treating head and neck cancer. DISCUSSION Before any of these approaches can be established in clinical routine, long-term data and standardization of the methods for isolating and analyzing the markers are needed.
