Molecular Oncology and Immunology


My group is interested in the dissection of the regulatory networks that shape human T cells functional plasticity in the context of tumor immune responses. We are mainly focused on T regulatory subsets that are central for the establishment of the tumor-dependent immunosuppressive mechanisms and ultimately contribute to dampening immune responses against cancer cells. Indeed, understanding the functional complexity and heterogeneity of human T cells cells in the tumor microenvironment is key to pave the way towards the development of novel and more specific immunomodulatory approaches for cancer treatment.


Ongoing research projects

Characterization of the molecular blueprints of T cell subsets at tumor site.
To dissect the hubs that instruct gene regulatory programs of immune cell landscape at tumor sites, we employ whole transcriptome along with single-cell RNA-sequencing that provides a thorough description of the underlying heterogeneity of T cell subsets in the tumor and metastatic microenvironment. Moreover, we take advantage of bioinformatic and computational pipelines to integrate transcriptome datasets with epigenomic profiling and unveil also cis-regulatory elements (e.g. enhancers) and other non-coding genomic features (e.g. long non-coding RNAs) that shape the identity of tumor infiltrating lymphocytes.

Charting the communication routes between immune and tumor cells.
A key aspect of tumor immune response is the crosstalk between tumor and immune cells, whose function is strongly influenced by their spatial localization and tissue context. To chart cell-spatial organization at tumor sites we are employing both enhanced single-molecule FISH approaches on pre-selected targets and spatial transcriptomics techniques based on in situ mRNA capturing coupled to standard RNA-seq (SLIDE-seq).

Modelling tumor-immune host interactions through organoid 3D cultures.
To fully understand the functional implication of the relationships between immune and tumor cells we are also exploiting organoids cell lines derived from both tumor and normal tissues. Organoids recapitulate the architecture and growth pattern of the tissue from which they originate and represent therefore an experimentally controllable model to assess the modulation of either tumor or T cell specific transcripts by gene editing approaches in an environment resembling the original tumor.
