Ana Isabel Matos has a bachelor degree in Biochemistry from the Faculty of Sciences and Technology of the New University of Lisbon and a master degree in Biochemistry from the Faculty of Sciences of the University of Lisbon.. Her PD-FCT AIM project is entitled “Combinatorial multivalent nanoplatform for colorectal cancer treatment”. This project takes place at the Faculty of Pharmacy of the University of Lisbon and INESC MN. The thesis is supervised by Helena Florindo (Faculty of Pharmacy of the University of Lisbon) and co-supervised by João Pedro Conde (INESC MN and Department of Bioengineering of Técnico). Her doctoral program started on October 1st 2015. Here is an abstract of Ana Isabel’s PhD project:
Per year, colorectal cancer (CRC) is responsible for 655,000 deaths throughout the world. Almost 70 % of CRC patients are diagnosed with metastatic disease, mainly hepatic metastases, and present a very low 5 -years survival rate. The heterogeneity of cancer cells has impaired the successful outcome of several therapeutic approaches, including surgery, chemotherapy and radiotherapy, requiring effective combinatorial approaches. Immunotherapeutic approaches have shown very positive outcomes in other disseminated malignant diseases. However, an effective strategy against the heterogeneous population of cancer cells requires a combinatory approach to modulate different cells and mechanisms involved in tumor growth and dissemination. COMBI-CRC will tackle this goal by developing a combinatorial multivalent nanoplatform for CRC immunotherapy and drug delivery. COMBI-CRC will comprise two types of polymeric nanoparticles able to carry different active molecules and conjugate engineered targeting moieties to in vivo target and modulate distinct cell populations:
- Nano_1: Immunotherapy based on dendritic cells (DCs)-targeted NPs,
- Nano_2: Drug delivery based on tumor microenvironment (TME)-targeted NPs.
Additionally, the cross talk between immune cells and CRC cells (CRCC) will also be assessed by reconstituting complex immune and tumor microenvironments on microfluidic chips. A simple microfluidic device will also be exploited to investigate the crosstalk between metastatic CRCC and T lymphocytes from defective immune system, to reproduce T lymphocytes-mediated antitumor activity and CRCC-mediated tumor metastasis. The contact and the release of soluble mediators between malignant and immune cells are crucial to mediate tumor growth and metastasis, in a process termed immunosurveillance. However, immunosurveillance mechanisms fail in conditions of immunodeficiency. Microfluidic chips have been developed to follow unexplored cell-cell interactions by co-culturing several types of cells, transposing in vivo studies to a second generation of in vitro smart environments. This highly innovative and technologically advanced chemically-defined nanoplatform will lead to a safe multivalent nanomedicine able to combine the effect of a cytotoxic drug at cancer site with a balanced and multi-targeted immunotherapy, which overall outcome can constitute a real hope for patients with metastatic CRC disease.
