Although activation of the mammalian target of rapamycin complex/p70 S6 kinase (S6K1) pathway by leucine is efficient to stimulate muscle protein synthesis, it can also exert inhibition on the early steps of insulin signaling leading to insulin resistance. We investigated the impact of 5-week leucine supplementation on insulin signaling and...

Several species are important for human affairs, being widely used in industry, such as the penicillin-producer P. rubens, the two...

Recent evidence supporting that adipose tissue (AT)-derived extracellular vesicles (EVs) carry an important part of the AT secretome led us to characterize the EV-adipokine profile. In addition to evidencing a high AT-derived EV secretion ability that is further increased by obesity, we identify enrichment of oligomeric forms of adiponectin in...
