I am working with the freshwater polyp Hydra, to be more detailed with its Nematocysts, the characteristic organelles of the phylum Cnidaria. These stinging organelles are assembled during a complex secretory process within a large post Golgi vesicle in specialized stem cell derivatives. Nematocysts are composed of many different proteins, giving rise to extraordinary features as elasticity, pressure resistance, stability and a complex discharge mechanism. Based on the elucidation of the nematocyst proteome my project is focused on novel components that define critical functional features of this organelle. To gain a better understanding of these I apply genetic and biochemical tools, fluorescence microscopy, in situ hybridization and I generate transgenic animals with reporter of fusion constructs.
