Sepsis remains a leading cause of death in hospitalized patients, despite the efficacy of the new antibiotics and the major advances in modern hospitals. These mortality rates remain high because new antibiotics are efficiently controlling the infection, but they do not control inflammation. Sepsis is one of the most lethal examples of inflammation as the overzealous systemic inflammation becomes more dangerous than the infection itself. Currently, most of the therapies are largely supportive and there is no effective treatment for severe sepsis. We reported that electrical vagal stimulation controls inflammation and improves survival in experimental models of sepsis. But, the clinical implications of this mechanism were limited by the surgical procedure required for electrical nerve stimulation. We recently reported that neuronal stimulation with transdermal neurostimulation prevented systemic inflammation and improved survival in experimental sepsis. Neurostimulation inhibited the production of inflammatory factors by inducing the production of dopamine from the adrenal medulla. From a pharmacological perspective, dopamine inhibited macrophage’s activation via D1-like dopaminergic receptor. Clinically, neural stimulation through neurostimulation is a promising strategy to control inflammation, but its efficacy is questioned due to the placebo effect. We also studied the effects of transdermal nerve stimulation with electroacupuncture in anesthetized patients during surgery, analyzing blood samples collected under general anesthesia to avoid any placebo effect. Electroacupuncture during surgery reduced the postoperative use of analgesics, physiological stress, hyperglycemia and inflammatory responses to trauma.

Arthur Germano Fett-Neto received a PhD in Plant Physiology and Biochemistry at the University of Toronto, Canada. He spent two years as Research Associate at Dartmouth College (USA), working on Plant Molecular Genetics. After two years as Visiting Professor, he joined the faculty of UFRGS, where he has been a Full Professor of Botany since 1999. His research interests have a focus on trees, including plant secondary metabolism (mostly indole alkaloids and terpenes), and adventitious root development. He has authored over 75 papers, 19 book chapters, edited 3 books, and is inventor of 6 patents.


Quillaja brasiliensis (Quillajaceae) is a native tree of southern Brazil, popularly known as soap tree. The barks of its congener species Q. saponaria are one of the main sources of saponins of industrial interest, mostly due to the immunoadjuvant properties of these secondary metabolites in vaccines. Saponins from leaves of Q. brasiliensis are remarkably similar to those of Q. saponaria barks, constituting a readily renewable source of biomass. These facts prompted investigations on the immunoadjuvant activity of Q. brasiliensis leaf saponins. The leaf aqueous extract and purified saponin fractions obtained from it showed strong immunoadjuvant activity with low toxicity in mouse experimental vaccines against bovine herpes virus 1 and 2, poliovirus, bovine viral diarrhea virus and rabies. Effective propagation protocols for Q. brasiliensis were developed from seeds, as well as by clonal strategies such as micropropagation and minicuttings. Callus and cell suspension cultures accumulating saponins were also established. Studies on the regulation of saponin biosynthesis in leaves revealed increased production upon specific stress conditions and signaling molecule treatments. Leaf postharvest procedures were also developed, further increasing saponin yields. Among the most stimulant treatments, considering both the pre and postharvest stage, were exposure to UV-C, osmolytes, salicylic acid, jasmonic acid, ultrasound, and leaf mechanical damage. These results indicate that saponin accumulation in this species may be involved in general defense responses against biotic and abiotic stresses. The combined approaches of sustainable plant biomass generation, saponin yield elicitation, and proof of immunoadjuvant activity in vaccines against different pathogens provide a solid platform for the industrial application of Q. brasiliensis and its saponins.
