Research interests: Membrane trafficking, Inflammation, Molecular neurodegeneration
Biography
Mari Chiritoiu graduated from Faculty of Chemistry, University of Bucharest (2004-2008) and received her Ph.D. in Biology from the Institute of Biochemistry of the Romanian Academy in 2014, under the supervision of dr. Stefana Petrescu. She was a posdoctoral fellow in the lab of prof. Vivek Malhotra, at CRG-Centre for Genomic Regulation, Barcelona, Spain (2016-2019) where she investigated the process of unconventional protein secretion using as model cargo the pro-inflammatory cytokine interleukin-1β.
In the future, dr. Chiritoiu aims to understand key aspects of the molecular mechanism of leaderless protein export, such as interleukin-1β and α-synuclein, related to inflammation and neurodegeneration.

Grants
High-throughput screening platform for small-molecules with anti-inflammatory potential
2020-2022
Acronym: HTS-IL-1β
Budget: 600.000 RON
Project director: Mari Chiritoiu
This project aims to develop a sensitive high-throughput screening platform by generating an endogenously tagged interleukin-1β reporter cell line by CRISPR-Cas9 technology, able to monitor stimulated IL-1β secretion with the purpose to identify new chemical compounds with anti-inflammatory activity that will be validated in primary macrophages and a mouse model for sepsis.
