- Igniting the flame in arthritis: C5aR2 controls endothelial transcytosis of C5a
C5aR2 transfers arthritic joint-derived C5a to the blood vessel endothelium to start C5aR1-driven neutrophilic inflammation. See related Research Article by Miyabe et al.

About The Cover
ONLINE COVER Adiposphere Mound. This month's cover shows a stack of two 3D organoids grown from distinct subtypes of mesenchymal stromal cells found in visceral adipose tissue. These spherical organoids were generated using adipogenic media and stained with dyes that bound to nuclear DNA (blue) or fat droplets (green). Spallanzani et al. used single-cell RNA sequencing to identify which subtypes of stromal cells within white fat make interleukin-33 (IL-33), a cytokine that supports maintenance of regulatory T cells and group 2 innate lymphoid cells within visceral adipose tissue.
