Rossella Paolini, PhD

Present Appointment:
Full Professor of Immunology, Department of Molecular Medicine "Sapienza”, University of Rome.

Rossella Paolini graduated at the University of Rome “La Sapienza” in 1986 and she obtained a PhD in Experimental Medicine within the same Department in 1992. During the last 2 years of the PhD course as fellow and then as a post-doc research associate, she spent 5-year training at the Section of Molecular Immunology and Allergy at NIH in Bethesda (1990-1995).
From 1991 to 2001 she was Researcher at the Department of Experimental Medicine, University of Rome “La Sapienza”. From 2001 to 2015 she was Associate Professor, and from 2016 she is Full Professor, Chair of Immunology at the Medical School of University of Rome “La Sapienza”.
Over the last 20 years, the main interests of Dr. Paolini have been focused on the study of signal transduction pathways implicated in the regulation of different aspects of mast cell and NK cell biology.
Her studies have importantly contributed to elucidate the intracellular biochemical events leading to the activation of mast cell functional program. In particular, she first demonstrated that FcεRI subunits undergo reversible tyrosine phosphorylation upon antigen stimulation and proposed that cycles of phosphorylation and dephosphorylation serve to maintain the propagation of intracellular signalling.
More recently, she has been focused on the molecular pathways that regulate expression and function of activating receptors and their ligands on mast cells and on Natural Killer cells.
These studies highlighted a critical contribution of the ubiquitin and the SUMO pathway in limiting the rate and the extent of NK and mast cell functional responses. In a recent publication she has also proposed a novel mechanism to amplify a pro-inflammatory response orchestrated by mast cell-released exosome-like vesicles.
The results obtained by Dr. Paolini have been published in highly qualified international journals and presented at many national and international congresses.

Scientific activity:
She is author of 36 peer-reviewed papers in the last 10 years with over 1200 citations.
H index 21 (15 years)

She has been involved in several national and international research projects in the past.
She is presently involved in the following research projects:

1. PI in the Grant from Istituto Pasteur Italia - Fondazione Cenci Bolognetti Call 2020: “Dissecting the role of mast cells during the transition from intestinal inflammation to colon cancer” Prot. 366. Timeline 2022-2023.
2. PI in the Grant from the Italian Association for Cancer Research: “Unraveling the role of mast cells in colorectal cancer”. Code 24955. Timeline 2021-2026.
3. Partner in the Special Program Molecular Clinical Oncology 5 per mille (AIRC 5xmille): “Immunity in Cancer Spreading and Metastasis (ISM)” (Code 21147). Timeline 2018-2025.
