“Circularly polarized luminescence and Raman optical activity in search of structural changes in proteins “

Supervisors: prof. dr hab. Małgorzata Barańska/ dr Grzegorz Zając

The Doctoral School of Exact and Natural Sciences MCB/JCET/Solaris invites applications for the position of a PhD student that will start on October 2022.

                              Project description:
 
Protein structural alterations play a key role in many civilization and neurodegenerative diseases, such as Alzheimer, Parkinson disease, diabetes, atherosclerosis and others. Typical protein structural changes upon disease state are the chemical modifications, mutation of the primary structure, modification of the secondary structure, as well as aggregation. [1] Chiroptical spectroscopy methods (methods sensitive to the chirality), have been recently proved to be very sensitive to the three dimensional structure of biomolecules. However, those methods usually hamper from the low intensity of the signal. As it recently turns, Raman optical activity (ROA) signal can be enhanced due to the aggregation and induction of the resonance conditions. Furthermore, another chiroptical method, CPL (circularly polarized luminescence), and CPL probes, could also increase the chiroptical sensitivity to the structural changes. [2]

The main scientific goal of the project is the chiroptical and structural analysis of the modification of proteins in the model and biological systems. The first task of the project is the study of the structural related spectral features of model, protein based systems in the monomeric, native form and in the alternated form (e.g. aggregated form) that mimicking biological systems, by means of various spectroscopic methods. The second aim is to study the interaction of CPL based probes with protein based systems. The third task is to study natural biological systems, primarily blood serum from different mice disease models, and study a potential of chiroptical differentiation of healthy and disease mice model samples by CPL/ROA probing.
