Bonjour from Paris, France !

In today’s digest you will find a wide variety of interesting preprints and published research papers encompassing very interesting microbiome such as Yak calves rumen, compost, wineyard soil and lichen symbionth microbiota!

If you are interested in virome, I recommend looking at the fascinating preprint from Ha and collaborators investigating the biogeography of giant viruses from the phylum Nucleocytoviricota. They leveraged the bioGEOTRACES metagenomic dataset collected across the Atlantic and Pacific Oceans to recovered novel genomes from these viruses and identified geographical patterns of distribution.

If you are working on human microbiomes, I recommend checking out a really interesting preprint, comparing the biases and strengths of four commercially available DNA extraction kits frequently used for whole genome shotgun analysis of the human microbiome.

Have a great Saturday!

Multi-omic interactions in the gut of children at the onset of islet autoimmunity – Patrick G Gavin – Microbiome

“Here, we apply an integrative approach to combine comprehensive fecal virome, microbiome, and metaproteome data sampled before and at the onset of islet autoimmunity in 40 children at increased risk of T1D […] We show a functional remodeling of the gut microbiota accompanies both islet autoimmunity and viral infection with a switch in function in Faecalibacterium occurring at the onset of islet autoimmunity.”

Highlights!

A microbiome-dependent gut-brain pathway regulates motivation for exercise – Lenka Dohnalová – Nature 

Here, we report on the discovery of a gut–brain connection in mice that enhances exercise performance by augmenting dopamine signalling during physical activity. We find that microbiome-dependent production of endocannabinoid metabolites in the gut stimulates the activity of TRPV1-expressing sensory neurons and thereby elevates dopamine levels in the ventral striatum during exercise.
