Structural and functional links between capsule and nephrogenic zone in fetal human kidney

Journal of Pediatric and Neonatal Individualized Medicine, 2018
Little attention received developmental aspects of the human kidney during the late phase of gestation. For healthy newborn babies this subject has no further meaning, since nephrogenesis proceeds unnoticed until birth.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
