Never as the past two years (2020-2021) have manifested the importance of the research in virology (and immunology). Readiness of action when such pandemic events occur rely on years of basic knowledge accumulated in time and constant technology development. The study of viruses infecting either Bacteria, Archaea or Eukaryotes – and whether from the basic, clinical or translation point of views – is always beneficial to society soon or later. The Abrescia Lab focuses on determining the molecular mechanisms governing viral pathogenesis using structural methods. We study virus assembly, virus cell entry, and virus-antibody recognition mechanisms. Deciphering the principles governing virus assembly allows developing molecular strategies for interfering with its morphogenesis. Expanding our structural knowledge of the virus world (Virosphere) also contributes to establish viral relationships that are undetected at sequence level. Elucidating the virus cell-entry processes provide the possibility of jamming this key-lock mechanism. Antibodies are often used to this purpose and understanding the recognition and neutralization processes greatly increase the possibility of tuning such mechanisms.

To this end, we use an integrative approach based on X-ray crystallography and Electron Microscopy (EM) techniques and complemented with functional studies. Specifically, access to high-end electron microscopy and crystallographic infrastructure is routinely available which allows the group to resolve viruses and viral protein structures to atomic detail. The generated knowledge is intended not only to elucidate molecular mechanisms but also to translate this knowledge into molecular tools (eg. drugs, diagnostics, vaccines) that would improve human and animal health.
Our research fulfils the ONE HEALTH concept and approach to societal challenges enabling the development of new intervention strategies.

Since 2014 the Abrescia Lab has been advocating the democratization of the cryo-EM technique and promoting it in the Basque Country:

Finally, Dr. Abrescia is the coordinator of the BAG-Bilbao for the Basque EM community to access state-of-the-art cryo-EM infrastructures at eBIC-Diamond (UK) for performing high-resolution cryo-EM studies on the topic of molecular recognition and host pathogens interactions.
