Prof. Reto Guler’s current research work focuses on the identification of host factors and pathways that are subverted by Leishmania major and Mycobacterium tuberculosis to increase its persistence and survival within macrophages with the aim to developing pathogen (Hlaka, Rosslee et al., 2017 and Scott et al., 2017) and host-directed drug therapy for tuberculosis and leishmaniasis (Guler and Brombacher 2015; Parihar, Guler et al. 2019). This includes the identification of statins and host non-coding RNAs as host-directed drug therapy for TB and leishmaniasis and the role of epigenetics in host immunity to TB. Reto Guler is a member of the international FANTOM consortium on genome-wide transcriptome analysis using CAGE transcriptomics (Nature, 2014;507; Science, 2015;347). His research further investigates Minor Groove Binders as novel anti-mycobacterial agents and non-ionic surfactant vesicles as a drug delivery system for tuberculosis. In collaboration, he investigates remodelling of mycobacterial peptidoglycan during cell division and in tuberculosis disease. The international PravaTB consortium has recently received a prestigious 4.9 million Euro award from the European & Developing Countries Clinical Trials Partnership (EDCTP) to conduct a clinical trial investigating the use of statins to prevent chronic lung inflammation and potentially TB relapse. The coordinator of this consortium is Reto Guler (University of Cape Town). Chief principal investigator of the clinical trial is Friedrich Thienemann (University of Zürich), local PI in Cape Town is Sandra Mukasa (University of Cape Town). Other project partners include Robert J. Wilkinson (Imperial College London), Claudia Schacht (LINQ Management GmbH, Germany), Gunar Günther and Emmanuel Nepolo (University of Namibia). He has have shown proof of productivity to actively manage collaborative research programs and foster student development.
