Imaging Lung Inflammation using PET: The Use of 18F-AzaFol and beyond
The Center for Radiopharmaceutical Sciences (CRS) focuses on the development of new radiopharmaceuticals for positron emission tomography (PET) and other applications in nuclear medicine. Researchers at CRS have previously developed an 18F-based PET tracer (18F-AzaFol) for targeting the folate receptor, which is expressed on tumor cells, but also on activated macrophages involved in inflammatory processes. In a recent clinical study, 18F-AzaFol was investigated regarding its in vivo properties for folate-receptor targeting and assessed with respect to its safety profile in patients (NCT03242993).
In an interdisciplinary project of PSI and the University Hospital Zurich, preclinical studies were performed to demonstrate the potential of 18F-AzaFol for imaging macrophages in lung inflammation. 18F-AzaFol was shown to accumulate specifically in diseased lung tissue but not in lungs of healthy mice. The increased abundance of folate receptor-expressing macrophages was confirmed on diseased murine and human lung tissue using several in vitro methods (Schniering et al, 2019 Front Immunol).
Alveolar macrophages play an important role during coronavirus infections and replication and are involved in antiviral response and defense mechanisms. Most importantly, acute respiratory distress syndrome, a complication that develops in approximately 20% of patients, results from exuberant host inflammatory responses with macrophages as key players. 18F-AzaFol/PET based macrophage imaging may thus, be useful to investigate the complex immune response to COVID-19 infection and possibly enable the development of personalized treatment regimens in the future.
In this context, also other targets may be of interest for nuclear imaging. Recently, it was suggested that integrin may act as an alternative receptor for SARS-CoV-2 and could be implicated in its transmission and pathology. Clinically used RGD radiopharmaceuticals for integrin targeting may, therefore, be considered as effective imaging tools. In a proof-of-concept study, increased accumulation of an RGD radiopharmaceutical was demonstrated in a preclinical setting of lung inflammation by the same research team (Schniering et al. 2018 Ann Rheum Dis).

PD Dr. Cristina Müller won the lecture award for the presentation of her work entitled "161Tb-based Prostate Cancer Therapy: Investigating the "177Lu-PLUS Effect"
The ETH Domain presented six successful start-ups at the WEF 2020 at the Institute for Snow and Avalanche Research in Davos
PSI and araris: So far, the active substances of certain cancer medications have been chemically attached to antibodies in order to eradicate the tumor cells. However, efficiency and tolerability were often rather poor. With a biological catalyst, the active ingredients can now be coupled site-specific and stoichiometric to an antibody. The in vivo characteristics of such immune conjugates are better than those of chemically manufactured analogues. If a radioactive molecule is attached at the same time, the antibody drug conjugate can be monitored in the body.
Janine Schniering won a ETH Medal and the EXCITE PhD Excellence Award for her outstanding PhD Thesis in 2019
Dr. Janine Schniering performed her thesis (entitled “Towards Precision Medicine in Systemic Sclerosis - Exploration of Novel Imaging Tools for Interstitial Lung Disease”) at the Paul Scherrer Institute (PSI) under the supervision of Prof. Dr. Roger Schibli and at the University Hospital Zurich (USZ) under the supervision of PD. Dr. Britta Maurer and Prof. Oliver Distler. Her work describes a multi-modal imaging approach across the scale (from cell to mouse to human) to exploit potential biomarkers and targets for the treatment and management of interstitial lung disease (ILD). ILD comprises a group of heterogeneous parenchymal lung disorders with high mortality, hard to specify diagnosis and difficult to manage treatment.

Mit Vitamin gegen Krebs
Forschung mit radioaktiv markierten Folsäure-Verbindungen
Täglich nehmen wir mit unserer Nahrung Folsäure auf. Dieses Vitamin ist wichtig für die Zellteilung und somit für das Wachstum. Doch in Zukunft könnte dem Vitamin noch eine weitere Rolle zukommen. Denn am PSI werden Therapien gegen Krebs entwickelt, die Folsäure nutzen.
The Center Radiopharmaceuticals Sciences is a member of the FP7 consortium “BetaCure”, a collaboration between 17 research institutions and companies throughout whole Europe. The aim of the project “Personalized diagnosis and treatment of hyperinsulinemic hypoglycaemia caused by beta-cell pathology” is to develop new treatment modalities for rare beta-cell derived hyperinsulinemic diseases like Nesidioblastosis or Insulinoma. Nesidioblastosis is a hyperplasia of the beta-cells which lead to a hyperproduction of insulin in newborns. Insulinomas are tumors derived from beta-cells. These diseases are potential life threatening because of its hypoglycemic pattern and have only limited therapeutic modalities. The consortium is clinical oriented with a strong part of preclinical research and has a close collaboration with patient organizations related to these diseases. The project started on 1st of April 2014.
Development of radiolabeled antibodies for clinical diagnosis of invasive Aspergillosis by PET imaging
The Center for Radiopharmaceutical Sciences is a research partner in the project entitled “New Molecular-Functional Imaging Technologies and Therapeutic Strategies for Theranostic of Invasive Aspergillosis” (MATHIAS) funded by the European Union in the 7th Framework Programme. The main goal of this collaborative project is the development of radiolabeled antibodies for clinical diagnosis of invasive Aspergillosis by PET imaging. The preclinical evaluation of different antibody fragments for imaging and radioimmunotherapy are additional goals of MATHIAS. The project started on 1st October 2013 and the duration of the project is five years.
