Happy to share this paper in final form rdcu.be/eH8tj, with more info on neuronal responses and potential mechanism of actions! The results suggest that there is neural interoception of microbial metabolic state 🧠🦠 We hope they can inspire more work in this area!

We are looking for a postdoc to study single-cell transcriptional heterogeneity in the human skin microbiome.

We have a new protocol mostly developed, but need someone to see it through. Experience with protocol dev or RNAseq appreciated.

Funded by a new grant from MIT-HEALS.

Authors argue that integrating metagenomics, culturing, and experimental validation to study hidden yet ecologically significant microbial species will advance our understanding of the microbiome in health and disease, and inform next-gen therapeutics leveraging the full diversity of the gut.

3/3 Why this matters: C-section babies have higher rates of asthma, allergies, and autoimmune conditions later in life. Early microbiome interventions during the critical infancy window could potentially prevent the 'atopic march' - need larger, longer studies to confirm!

2/3 Key findings from the study:
• ⬆️ Bifidobacterium abundance (p=0.025)
• ⬆️ HMO degradation genes (α-L-fucosidase, p=0.019)
• C-section index normalized to vaginal birth levels
• Atopic dermatitis OR 0.17 (95% CI: 0.023-0.723, p=0.031)

This study published today finds "a more diverse gut microbiome is generally associated with healthier glucose spike metrics." It's certainly not implying causality, but it is very interesting to see the association!
