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 ...

TAU researcher advances novel strategy to fight cancer by shoring up the immune system Two years ago, Prof. Eshel Ben-Jacob of Tel Aviv University‘s School of Physics and Astronomy and Rice University’s Center for Theoretical Biological Physics made the startling ...

The immune system of cancer patients is often suppressed. Accumulating evidence suggests that exosomes released from tumor cells may play an essential role in this process but the mechanisms are not fully understood. Here the authors review recent papers showing ...

Brett Smith for redOrbit.com – Your Universe Online For years, doctors have wondered why someone with an anthrax infection can die days after the bacteria responsible is wiped out from their body. A new study claims the toxin produced by ...
