#### **Jos ´e Miguel Ferreras**

Jose Miguel Ferreras (Prof., PhD) is a Full Professor (since 2016) in Biochemistry and Molecular ´ Biology at the Department of Biochemistry and Molecular Biology and Physiology, University of Valladolid, Spain. His research activity is based on four main fields, concerning i) the study of protein synthesis inhibition, ii) the research on ribosome-inactivating proteins (RIPs) from plants, iii) the design and the in vitro and in vivo experimentation of immunotoxins and other conjugates in order to obtain molecules targeted specifically against cells responsible for a pathological state, and iv) the study of ribotoxins from fungi. Prof. Ferreras has co-authored more than one hundred scientific papers.

#### **Luc´ıa Citores**

Luc´ıa Citores (Prof., PhD) studied Chemistry at the University of Valladolid, Spain, and completed her PhD in Biochemistry at the same University. From 1997 to 2004 she worked at the Institute for Cancer Research in Oslo, Norway, as a postdoctoral researcher. During this time, she became interested in the endocytosis and intracellular transport of fibroblast growth factors and their receptors. She returned to Spain in 2004 as a postdoctoral researcher from the program Ramon y ´ Cajal and in 2011 she was appointed as Associated Professor in Biochemistry and Molecular Biology at the University of Valladolid. Her research interests have focused on distribution, activity, structure and applications of ribosome-inactivating proteins and ribotoxins and how they enter and intoxicate mammalian and fungal cells.
