Single-cell RNA sequencing identifies senescence as therapeutic target in rhabdomyolysis-induced acute kidney injury.

Background: The role of macrophages in the development of rhabdomyolysis-induced acute kidney injury (RM-AKI) has been established, but an in-depth understanding of the changes in the immune landscape could help to improve targeted strategies. Whereas senescence is usually associated with chronic kidney processes, we also wished to explore whether senescence could also occur in AKI and whether senolytics could act on immune cells.

Methods: Single-cell RNA sequencing was used in the murine glycerol-induced RM-AKI model to dissect the transcriptomic characteristics of CD45+ live cells sorted from kidneys 2 days after injury.

Pyoderma gangrenosum at an episiotomy site in successive pregnancies: A case report.

Pyoderma gangrenosum (PG) is an ulcerative, neutrophil-predominant inflammatory disease of the skin that commonly presents as painful ulcers. PG during pregnancy is extremely rare. We report the case of a 28-year-old woman with a painful, rapidly progressive ulcerative lesion at an episiotomy site presenting 16 days following a vaginal delivery.
