Extracellular glutamine is essential in cell division and flagellar function in bloodstream forms of Trypanosoma brucei

Flávia Silva Damasceno, Sabrina Marsiccobetre, Rodolpho Ornitz Oliveira Souza, Matheus Issa, Otávio Henrique Thiemann, Andrea Sorrentino, Katherine Figarella, Michael Duszenko, Ariel Mariano Silber

This study shows that extracellular glutamine is critical for cell division and flagellar function in Trypanosoma brucei bloodstream forms, with its absence leading to polyploid, multiflagellated cells and proteome glutamylation changes.

Branched chain amino acids modulate the proteomic profile of Pro-induced differentiation for the infective stages of Trypanosoma cruzi

Janaina De Freitas Nascimento, Flávia Silva Damasceno, Sabrina Marsiccobetre, Francisca Natália de Luna Vitorino, Renan Weege Achjian, Júlia Pinheiro Chagas da Cunha, Ariel Mariano Silber

This study investigates how branched-chain amino acids (BCAAs) affect the proteomic profile of Pro-induced differentiation in Trypanosoma cruzi, revealing metabolic changes linked to reduced infectivity.
