Shiitake vesicles held 69.25% of added curcumin in particles under 200 nm and kept it stable through simulated digestion. In mice the curcumin stayed in the intestine longer, and in human stool cultures the vesicles were taken up mostly by Bacteroidaceae and Lactobacillaceae.

mushroom vesicles
Fungi talk in vesicles too. The research is young, and I will show you exactly how young.
I get asked about mushroom supplements constantly, so I went looking for the vesicle evidence behind them. There is far less than the marketing suggests, and I would rather show you the size of the gap than fill it with fungal papers about something else.

the short version
what the research found
the headline numbers
-
Vesicles were isolated from seven commonly eaten mushrooms, and only the shiitake vesicles blocked a key inflammation switch, the NLRP3 inflammasome, in immune cells.
-
Aged mice given shiitake vesicles by mouth every week for nine months did better on cognitive tests. Labeled vesicles never reached the brain, so the effect ran through the gut.
-
Shiitake vesicles carried 69% of added curcumin in particles under 200 nm and kept it stable through simulated digestion.
-
Growing temperature changed vesicle output about six-fold in one edible mushroom, from 1.22 × 10⁹ to 7.31 × 10⁹ particles per mL.
-
Fungal vesicles are not automatically friendly: inside a Candida biofilm they build the matrix that makes the fungus harder to kill with antifungal drugs.
-
Researchers inside the field say fungal vesicle effects are contradictory and that basics like their half-life in the body are still unknown.
the nano angle
Fungi do release vesicles, and that has been solid since 2007 in species that cause infections. The work on the mushrooms people actually eat is new and thin, and I have kept the two clearly apart.
my honest bottom line
Edible mushroom vesicles exist, can be isolated, and have done interesting things in mice, but I count only a handful of species studied and no human data at all. Most of what we know about fungal vesicles still comes from infection research, where the same vesicles can help the fungus as easily as the host.

Temperature was the biggest driver of vesicle output in Pleurotus tuber-regium, an edible oyster mushroom relative: 7.31 × 10⁹ particles per mL at 34 °C versus 1.22 × 10⁹ at 30 °C. The vesicles carried ribosome, proteasome and redox proteins plus microRNAs not described before.
Aged mice got shiitake vesicles by mouth once a week from 13 to 22 months of age and did better on cognitive tests. Labeled vesicles did not reach the brain. Instead the vesicles shifted gut bacteria and lowered a tryptophan byproduct called kynurenic acid.
Vesicles were isolated from both the fruiting body and the root-like mycelium of king oyster mushroom and confirmed by particle tracking, electron microscopy and protein markers. The mycelium gave more vesicles and stronger antioxidant activity in four standard lab tests.
Vesicles from cultivated Cordyceps militaris carried protein, fats, flavonoids and alkaloids. They shifted immune cells called macrophages into an active state in dishes and in mice, and eased the immune suppression caused by the drug cyclophosphamide in that model.
Two yeasts isolated from a fermented milk drink released vesicles that human immune cells took in, after which those cells presented antigen less actively. Most of the RNA inside was fragments of yeast messenger RNA.

Vesicles from seven commonly eaten mushrooms all carried RNA, protein and fats, but only shiitake vesicles blocked NLRP3 inflammasome assembly in immune cells, lowering IL-6 and IL-1β. Giving them ahead of time reduced liver injury in mice exposed to galactosamine and LPS.
Vesicles released inside a Candida biofilm built its protective matrix and made the fungus more tolerant of antifungal drugs. Mutants that could not make vesicles normally lost that protection.
Immune cells took up vesicles from Cryptococcus and answered by releasing more TNF-α, IL-10 and TGF-β, and more nitric oxide as the dose rose. Those immune cells then killed the yeast more effectively.
Researchers inside the field lay out the contradictions: the same fungal vesicles help infection in one experiment and protect vaccinated animals in another, and basics like stability and half-life in the body are not established.
A review of how organisms with thick walls (fungi, Gram-positive bacteria and mycobacteria) still manage to release vesicles, and what they carry. It explains why vesicles escaping a fungus were such a surprise.
The study that showed fungi send material out in vesicles that cross their tough cell wall. The yeast Cryptococcus neoformans released vesicles carrying its capsule sugar, a signaling fat and sterols, both in culture and during infection.
