O Controle de qualidade de proteína (CQP) consiste na supervisão e no processamento de proteínas danificadas por meio de processos catalíticos (proteassoma e autofagia). Nesse estudo, caracterizamos o CQP, bem como os benefícios da ativação β2-adrenérgica (β2-AR) modulador positivo do CQP, em modelo animal de disfunção/atrofia muscular induzida por constrição crônica do nervo isquiático (CCI). Observamos que, apesar de um aumento na atividade catalítica, a atrofia está associada à um CQP insuficiente, detectado por um acúmulo de proteínas citotóxicas nessa musculatura. O tratamento com Formoterol (agonista β2-AR) aumentou a atividade proteassomal e restaurou o fluxo de degradação via autofagia, resultando na melhora do CQP e...
