Expansion microscopy reveals insulin granule clustering in human β-cells in type 2 diabetes

Licia Anna Pugliese, Valentina De Lorenzi, Gianmarco Ferri, Ha Vo, Allison Lindquist, Marta Tesi, Carmela De Luca, Mara Suleiman, Lorella Marselli, Yongxin Zhao, Piero Marchetti, Fabio Beltram, Francesco Cardarelli

This study uses expansion microscopy to analyze insulin granule organization in human β-cells, finding increased clustering in type 2 diabetes without significant granule depletion.

Autofluorescence intensity patterns encode α/β cell identity in human islets

Ivano Squiccimarro, Fabio Azzarello, Valentina De Lorenzi, Francesco Raimondi, Andrea Ghelli, Fabio Beltram, Francesco Cardarelli

This paper shows that endogenous autofluorescence patterns can distinguish α and β cells in human islets without labeling, using LTP descriptors and morphological features.
