Auricular Acupuncture and biomedical research——A Promising Sino-Austrian research Cooperation

Treatment by auricular acupuncture has a long history. Ear-acupoint research has been advancing step by step in China and also in Europe. Auricles are rich in nerves, therefore a close relationship with different functions of the human body has been proved by the research teams of the two main authors of this article from China and Austria. In recent years, great progress has been made in the research of regulating human body functions through electroacupuncture at the auricular branch of the vagus nerve, which is part of auricular acupuncture therapy. It is well known that the auricular branch of the vagus nerve is the only peripheral pathway to the cerebral cortex. Studies of the Chinese team on hypertension, diabetes, epilepsy and depression have shown that the mechanism of auricular vagus nerve stimulation （VNS） may be comparable with cervical VNS in terms of pathways. Auricular VNS has a broad clinical application prospect.

Cone snail venoms have been considered a valuable treasure for international scientists and businessmen, mainly due to theirpharmacological applications in development of marine drugs for treatment of various human diseases. To date, around 800Conus species are recorded, and each of them produces over 1,000 venom peptides (termed as conopeptides or conotoxins).This reflects the high diversity and complexity of cone snails, although most of their venoms are still *** multiomics (such as genomics, transcriptomics, and proteomics) approaches have been recently developed to minediverse Conus venom samples, with the main aim to predict and identify potentially interesting conopeptides in an efficientway. Some bioinformatics techniques have been applied to predict and design novel conopeptide sequences, related targets, andtheir binding modes. This review provides an overview of current knowledge on the high diversity of conopeptides andmultiomics advances in high-throughput prediction of novel conopeptide sequences, as well as molecular modeling and designof potential drugs based on the predicted or validated interactions between these toxins and their molecular targets.
