Exploring the Proteomic Landscape and Immunomodulatory Functions of Derived Extracellular Vesicles.

Extracellular vesicles (EVs) have garnered attention in research for their potential as biochemical transporters and immune modulators, crucial for regulating the host immune system. The present study was conducted to isolate and characterize EVs from Gram negative bacteria (EVs) and investigate their proteomic profile and immune responses. Isolation of EVs was carried out using ultracentrifugation method.

Aortic Angiosarcoma Manifesting as Multiple Musculoskeletal Metastases: A Case Report.

Aortic angiosarcomas are rare. Due to its rarity and metastatic presentation, it is difficult to diagnose metastatic aortic angiosarcoma. We describe the clinicopathological and radiologic features of a metastatic aortic angiosarcoma presenting as musculoskeletal metastases.

In-vitro immunomodulatory responses and antiviral activities of antimicrobial peptide octominin against fish pathogenic viruses.

Antimicrobial peptides (AMPs) are considered a novel approach to stimulate fish antiviral mechanisms for defense against a broad range of viral infections by enhancing immunomodulatory activities. Octominin is an AMP derived from the defense proteins of Octopus minor. In this study, preliminary screening of octominin against viral hemorrhagic septicemia virus (VHSV), infectious hematopoietic necrosis virus (IHNV), and infectious pancreatic necrosis virus (IPNV) was carried out.

Antifungal Efficacy of Antimicrobial Peptide Octominin II against .

Most clinically isolated strains are drug-resistant, emphasizing the urgent need to discover alternative therapies. In this study, the previously characterized Octominin was modified into a shorter peptide with an 18 amino acid sequence (GWLIRGAIHAGKAIHGLI) and named Octominin II. The secondary structure of Octominin II is a random coil with a helical turn and a positive charge (+2.
