Defensosomes versus COVID-19

In a recent study published in the journal PLoS Biology, researchers investigated the role of angiotensin-converting enzyme 2 (ACE2)-containing defensive exosomes, or 'defensosomes' against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections.

RNA exosomes play a key role in B cell development, UTSW study suggests

New research from UT Southwestern suggests that RNA exosomes – the cellular machines that degrade old molecules of RNA – play a key role in the development of B cells, which are critical to the immune system's ability to protect against infection.

Cryo-EM helps scientists to decipher the structure of a key part of RNA degradation machinery

In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house.

Exosomes derived from γδ-T cells synergized with radiotherapy can control nasopharyngeal carcinoma

A research team at LKS Faculty of Medicine, The University of Hong Kong discovered that exosomes derived from γδ-T cells (γδ-T-Exos) synergised with radiotherapy can control nasopharyngeal carcinoma (NPC) by overcoming the radioresistance of NPC cancer stem cells (CSCs) and preserve their tumor-killing and T cell-promoting activities in the immunosuppressive NPC microenvironment.

Novel strategy can shrink tumors and prolong survival in mice

A research team based at the University of Ottawa and The Ottawa Hospital has developed a virus that infects and kills cancer cells without harming normal cells, while also sending out signals to prepare nearby uninfected cancer cells for viral attack.

Lower exosome component 2 expression protects against clinical SARS-CoV-2 infection

In a recent study posted to the bioRxiv* preprint server, researchers demonstrated that the lower expression of EXOSC2 human protein safeguards from clinical coronavirus disease 2019 (COVID-19). This protective effect was via the reduced EXOSC2 expression-associated suppression of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication.
