MitoEAGLE Short-Term Scientific Mission

Motivation letter
I am writing this letter to apply for the Short-Term Scientific Mission (STSM) covered by MitoEAGLE–COST Action CA15203 (1st Call for STSM Applications).
My name is Tímea Komlódi. I studied at Semmelweis University at the Faculty of Pharmacy. After graduation, in 2013, I started working as a PhD student at the Semmelweis University in the Department of Medical Biochemistry, Hungary.
My main topic of interest is energy metabolism and mitochondrial homeostasis under physiological and pathological conditions. Our group focuses mainly on neurodegenerative diseases like Alzheimer’s and Parkinson’s disease, which are attributed to mitochondrial dysfunction. I have experience in measurement of mitochondrial respiration, ATP synthesis, membrane potential, reactive oxygen species production and intra- and extramitochondrial pH detection.
In the future I am planning to deepen my knowledge about mitochondria and to expand it towards cell lines. The STSM grant would give the opportunity to deal with mitochondrial physiology and cell lines at the Oroboros Instruments in Innsbruck. The focus of the STSM project is the standardization of protocols in mitochondrial respirometry which could contribute to the scientific objective of MitoEAGLE. During the 8-day STSM mission I could acquire new measurement protocols which could be applied in future projects. These are the planned program of the STSM mission: 1.) detection of reactive oxygen species production of permeabilized cells using fluorescent probes; 2.) determination of mitochondrial membrane potential with safranin, TMRM and TPP+; 3.) assessment of mitochondrial P/O ratio by measuring ATP levels fluorometrically.
The STSM training would provide a platform for an international discussion and standardization of protocols, data and measurement techniques. Furthermore, the STSM project could be a basis of a flourishing cooperation with the Oroboros laboratory in Innsbruck in the near future.
I would like to participate in the MitoEAGLE projects because it provides the opportunity to
take part in data establishment and comparison of data between different research groups.
Moreover, Oroboros laboratory would provide a platform with its instrumental background,with its protocols and with its international connections to the objectives and aim of MitoEAGLE.
