Mitochondrial Metabolism and Calcium Handling in Parkinsons Disease hiPSC-derived Astrocytes

Giovanna C. Cavalcante, Camille C. Caldeira da Silva, Éverton Lopes Vogt…·Alicia Juliana Kowaltowski

This study examines mitochondrial calcium homeostasis and bioenergetics in hiPSC-derived astrocytes with LRRK2 and PRKN mutations, finding altered calcium dynamics and mitochondrial morphology in PD-related mutants.

Transcriptomic and functional profiling reveal autophagy inhibition and persistent bioenergetic collapse following parallel photodamage to lysosomes and mitochondria

Márcia Silvana Freire Franco, Felipe Gustavo Ravagnani, Suely Kazue Nagahashi Marie…·Maurício S. Baptista

This study shows that DMMB-induced photodamage causes transcriptomic changes similar to autophagy inhibition and persistent mitochondrial dysfunction.
