SIB Sezione Giovani/FEBS Junior Sections present Loredano Pollegioni

June 9, 2022 @ 6:00 pm to 7:00 pm CEST

Italy FEBS

    FEBS Junior Sections initiative  
Students and young researchers from some of the FEBS national Societies have started the FEBS Junior Sections initiative, a network of young scientists in the molecular life sciences across Europe. Their next event is a careers talk (organized by the SIB Sezione Giovani, the Junior Section of the Italian Society) on the research path that led to obtaining a drug in the clinical phase bought by Takeda.

These are the details of the May talk:

Speaker:   Prof. Loredano Pollegioni, Università degli Studi dell’Insubria, Italy
Topic:     “D-Serine: from unnatural (and negligible) amino acid to (main) neuromodulator involved in relevant human pathologies”
Time:         9 June 2022, 18:00 (CEST)
For more information, see abstract below, the FEBS Network, and Professor Loredano Pollegioni’s webpage.

On this talk Prof. Pollegioni will talk about the research path that led to obtaining a drug in the clinical phase bought by Takeda.

Amino acids have an α-carbon that is a stereocenter (or chiral center) since it is connected to four different functional groups. Depending on the spatial arrangement of these four groups, two enantiomers exist: the levorotatory (L-) and the dextrorotatory (D-), which are not superimposable images to each other. At difference from the interest attracted by the L-amino acids, less is known about the biological function of the D-amino acids (D-AAs) in mammals.

D-Serine is the D-AA present at the highest concentration in human brain: it plays a key role in the modulation of N-methyl-D-aspartate receptors (NMDARs) acting as an endogenous co-agonist. In the human CNS, D-serine is produced by the racemization reaction catalyzed by serine racemase and degraded by both serine racemase and D-amino acid oxidase (hDAAO). Abnormal levels of D-serine, due to a defective metabolism or release, have been associated with psychiatric and neurodegenerative diseases (e.g., schizophrenia, bipolar disorder, AD, ALS, etc.). To shed light on the regulation of D-serine level in the brain, we investigated the structural and biochemical properties of hDAAO: this flavoenzyme is regulated by small size ligands, cofactor binding, the interaction with specific proteins and post-translational modifications. These studies are opening new options to modulate NMDAR-mediated neurotransmission in physiological and pathological conditions.
