In ACS Nano, researchers report a nanomembrane system that harvests and purifies tiny blobs called exosomes from tears, allowing researchers to quickly analyze them for disease biomarkers. Dubbed iTEARS, the platform could enable more efficient and less invasive diagnoses for many diseases.

Inhalable COVID-19 Vaccine Shows Promise in Rodent Model
Researchers have created an inhalable COVID-19 vaccine that is shelf stable at room temperature for up to three months, targets the lungs specifically and effectively, and allows for self-administration via an inhaler.
Study to Examine Exosomes in Ovarian Cancer
Researchers have been awarded a $3.1 million grant from the National Institutes of Health to investigate more effective ways to identify ovarian cancer earlier.
Reopen and Regenerate: Exosome-Coated Stent Heals Vascular Injury, Repairs Damaged Tissue
An exosome-coated stent with a “smart-release” trigger could prevent reopened blood vessels from narrowing and deliver regenerative stem cell-derived therapy to blood-starved, or ischemic, tissue.

New strategy blocks chronic lung disease in mice
A new study from Washington University School of Medicine in St. Louis has uncovered a previously unknown role for exosomes in inflammatory respiratory diseases. The study has implications for finding new therapies. Exosomes are tiny compartments released from cells that carry different types of cargo, including inflammatory chemicals called cytokines that can drive lung disease.

Scientists ‘Farm’ Natural Killer Cells in Novel Cancer Fighting Approach
Engineers and oncologists teamed to develop a microfluidic chip capable of capturing the body’s natural killer immune cells to harvest their cancer-killing exosomes.

Exosome treatment improves recovery from heart attacks in a preclinical study
Research in pigs shows that using the exosomes naturally produced from a mix of heart muscle, endothelial and smooth muscle cells — all derived from human induced pluripotent stem cells — yields regenerative benefits equivalent to the injected human induced pluripotent stem cell-cardiac cells.

Scientists have developed a new gene-therapy technique by transforming human cells into mass producers of tiny nano-sized particles full of genetic material that has the potential to reverse disease processes.
