Mice that received the stem cell–derived treatment were less frail compared with controls, a study reports.

Vesicles containing fragments of the organelles released from stressed adipocytes protect the heart against oxygen deprivation, a study in mice shows.

The discovery suggests that the immune checkpoint can operate at a further distance from tumor cells than previously believed.

In mice and flies, the Arc protein forms capsids and carries genetic information.

Time-lapse imaging shows the immune cells transferring chemical signals during pigment pattern formation in developing zebrafish.

Immune cells called macrophages shuttle cellular messages in the skin.

Results from experiments in mice revise a long-held hypothesis that certain protein scaffolds are needed for synaptic activity.

Electron microscopy led to the first identification of what would later be known as ribosomes.

Nobel Laureate Christian de Duve discusses the impact of George Palade’s work on ribosomes.

Scientists present the first evidence that marine cyanobacteria release vesicles—billions and billions of vesicles.

Nobels awarded for vesicle trafficking and computational chemistry; building 3-D microbial communities; mislabeled microbes cause retractions

James Rothman, Randy Schekman, and Thomas Südhof share Nobel Prize in Medicine or Physiology.  

Using tiny lipid discs, scientists resolve contradictory evidence about how many proteins are required for neurotransmitter release.

Vesicles released by melanoma cells stimulate pro-metastasis behaviors in bone marrow cells.

There are five steps of autophagosome biogenesis: induction, expansion, vesicle completion, fusion, and cargo degradation. 

Despite years of research, the longstanding mystery of where the autophagosome gets its double lipid bilayers is not much clearer.

These small membrane vesicles do much more than clean up a cell’s trash—they also carry signals to distant parts of the body, where they can impact multiple dimensions of cellular life.
