Extracellular vesicles called F-ApoEVs mark the site of dying cells, guiding immune clearance while revealing how viruses can exploit this process to spread infection...

Researchers developed a new phosphatidylserine-binding reagent that reveals most extracellular vesicles in blood are PS-positive, enabling precise tracking of their turnover and potential therapeutic...

Researchers discovered that endothelial cells send β-catenin back to fat cells via extracellular vesicles called exosomes, helping maintain metabolic balance and revealing new insights into obesity and insulin...

A new protocol using atomic force microscopy infrared spectroscopy (AFM-IR) enables the analysis of extracellular vesicles at the single-vesicle level, providing valuable insights into their chemical composition and potential role in immune system...

Discovery May Help Explain Immunotherapy Resistance, Hints at New Therapies Immunotherapy drugs known as checkpoint inhibitors have revolutionized cancer treatment: many patients with malignancies that until recently would have been considered untreatable are experiencing long-term remissions. But the majority of ...

Researchers can now explain how a cell that is being attacked by bacteria or viruses specifically manages to ‘sound the alarm’ among its neighbouring cells...

Extracellular vesicles (EVs), or exosomes, are nanovesicles of endocytic origin that carry host and pathogen-derived protein, nucleic acid, and lipid cargos. They are secreted by most cell types and play important roles in normal cell-to-cell communications but can also spread ...

Exosomes (Exo) are small vesicles produced by melanoma cells and the accessory cells of the tumor microenvironment. They emerge via both classical and direct pathways and actively participate in tumor colonisation of distant tissues. The proteins, nucleic acids, cytokines and ...

An unexpected role for a white blood cell called the Natural Killer (NK) cell – a critical cell for ridding the body of infection and cancer, has been discovered by researchers at New Zealand’s University of Otago . The NK ...

In Type 1 Diabetes, the immune system attacks the beta cells, the insulin producing cells that reside in the islets of Langerhans region of the pancreas from Live Science by Tia Ghose – In people with type 1 diabetes, the ...
