For #JEMjc this month, @jem.org would like to highlight the recent work from Dr. Arkady Akhoutorsky @mcgill.ca and colleagues who identified a role for gut microbiota in mediating pain in fibromyalgia. Check it out here 👉 www.cell.com/neuron/fullt...
The gut microbiota promotes pain in fibromyalgia
Cai et al. revealed that transplanting gut microbiota from women with fibromyalgia—a chronic widespread pain condition of unknown etiology—into mice induces pain. It also induces phenotypes commonly o...

For September’s #JEMjc we would like to highlight the recent description of septal macrophages controlling adipocyte tissue plasticity www.science.org/doi/10.1126/...
Septal LYVE1+ macrophages control adipocyte stem cell adipogenic potential
Tissue macrophages reside in anatomically distinct subtissular niches that shape their identity and function. In white adipose tissue (WAT), we identified three macrophage populations with distinct lo...

IgA-driven neutrophil activation underlies severe dengue disease after primary Zika virus infection in humans - Nature Immunology
This study reveals that anti-NS1 IgA antibodies in plasma, induced by prior Zika virus infection, activate neutrophils, underlying severe dengue disease upon a subsequent DENV2 infection, uncovering a...
