1/12 🧵 My PhD thesis is out! “Host genetics shapes crypt/mucus niche colonisation by keystone gut bacteria, influencing metabolic health” (https://t.co/hYn4AViNJS). Let’s go through the main points 😉
How to measure microbiome health?
Commentary proposes adaptive coherence: capacity of host-microbiome systems to sustain integrated function via reorganization. Reframes health as emergent & relational, w/measurements of adaptability/functional integrity

Microbes as architects of colonic patterning
Highlight of @CellCellPress paper discovering regionalization of colonic epithelium depends on microbes, with proximal identity regulated by microbial nicotinic acid-induced PPARα activation in the epithelium.

Fascinating oral and gut microbiome study which concludes …
‘… several diseases and conditions that are currently considered non-communicable should be re-evaluated’

What happens in the gut doesn't stay in the gut
@ChristophThaiss et al. identified a pathway linking microbial and metabolic changes over the lifespan, peripheral inflammation, vagus nerve dysfunction, and reduced memory formation:

But why are probiotics alone insufficient for sustained gut microbiota modulation?

Scientists linked chronic fatigue to a deficiency in butyrate-producing bacteria.
Recent breakthroughs published in Cell Host & Microbe and Nature Medicine have uncovered a profound connection between the gut microbiome and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Researchers from Columbia University and the Jackson Laboratory found that patients suffering from this debilitating condition often lack specific health-promoting bacteria, most notably Faecalibacterium prausnitzii. This deficiency leads to a critical shortage of butyrate, a short-chain fatty acid essential for maintaining the gut barrier and regulating energy metabolism. Without these vital microbial components, the body enters what experts describe as a "gut-driven energy crisis," directly impacting a patient's physical and mental stamina.
The implications of these findings are transformative for the millions of people living with chronic fatigue. The studies demonstrated that the reduction of beneficial microbial species like Roseburia and Coprococcus is directly correlated with the severity of a patient's symptoms. By pinpointing these specific biological markers, scientists are now closer than ever to developing precise diagnostic tools and therapeutic interventions that target the microbiome. Rather than treating fatigue as a vague symptom, medical professionals can now look toward restorative gut treatments as a viable path to reclaiming energy and health.

According to a new study, wheat fiber-enriched foods may reduce gut inflammation and curb the development of inflammatory bowel disease. https://t.co/rtDpixZzFo
Is it time to explore the brain microbiome?
Recent findings in @PLOSBiology observed translocation of bacteria from the gut to the brain via the vagus nerve in mice:

Check out our latest pre-print on @biorxivpreprint ! We show that the intestinal MHC II self-ligandome is spatially compartmentalized across villus, crypt, and immune niches, and is dramatically rewired during injury toward damage-associated self-antigens.

Gut phage ACRs
Type II CRISPR-Cas systems dominate human gut w/diverse phage Acrs targeting these systems. Widespread family, GutAcraca, adopts similar structures to inhibit Cas9 & regulate its own expression, highlighting phage adaptation to gut ecology
