Short-Term Scientific Missions (STSMs) within the OneHealthdrugs (CA21111) network
1st CALL for applications 2023

The 1st STSM Call of the Action CA2111 OneHealthdrugs is launched. Short Term Scientific Mission (STSM) is for PhD students and postdocs, or young scientists, wishing to spend 3 months in a European or associated country, or in Africa (Cameroon, Gabon, Togo, ...). These grants (about 9 grants of 3000 euros) have to be spent before the end of August 2023.

Evaluation process: on a ”first come first served” basis.
Call closure: when all STSMs are granted/STSM budget is allocated.

NOTE: STSM must be concluded before 31/08/2023.

Each Application must be submitted form the Applicant’s user profile on the e-COST portal:, and then :

The documents that the Applicant must upload into the e-COST are:

  • STSM grant Application (based on the "STSM-application-template CA21111"; disregard the e-COST template)
  • Confirmation of the host on the agreement from the host institution in receiving the applicant
  • Other documents required by the Action [i.e. 1) Letter of support from the Home Institution; 2) CV; 3) Signed statement. The contents of the documents 1, 2 and 3 are detailed in pp6-7 of the "1stSTSM call for applications CA21111 - Guidelines"]

In attachment the Application Form template, Guidelines for this call and Userguide for applications into the e-COST portal. For inquiries, please refer to the Grant Award Coordinator, Dr. Elisabeth Davioud-Charvet (elisabeth.davioud (at)





Les derniers travaux de Rania Najm, Hiba El Hajj, Maryse Lebrun & leurs collègues sont publiés dans PNAS. Les auteurs apportent des connaissances importantes sur les acteurs moléculaires de l'invasion des bradyzoïtes et développent une stratégie vaccinale ciblant l'invasion des bradyzoïtes et des tachyzoites de Toxoplasma gondii.

LabEx ParaFrap wishes you happiness, health, science and success for 2023.

First news from the network this year: the ParaFrap webinars will be back in 2023, as in previous years, every second Thursday of the month at 3pm. If you are not yet on the webinar mailing list to receive all the information, sign up.

Voeux 2023


Gerald Spaeth, head of the "Molecular Parasitology and Signalling" unit at the Institut Pasteur Paris, has been awarded a Synergy grant from the European Research Council (ERC) for the project "DECOLeishRN - Decoding epistatic genome/RNome interactions in ekaryotic fitness gain using Leishmania parasites as a unique model system". This project is funded at over 9 millions Euros and will be conducted in collaboration with two Israeli teams led by Shulamit Michaeli (Bar-Ilan University) and Yitzhak Pilpel (Weizmann Institute of Science).

Exploiting the unique biology of the protozoan parasite Leishmania as a model system, the project will generate unprecedented insight into the role of genome instability in eukaryotic adaptation by combining experimental evolution, analyses of the non-coding RNA, network modelling and cutting-edge, single cell sequencing. The project aims to uncover the molecular filter that can mitigate toxic effects of genome instability while promoting beneficial ones, thus resolving a long-standing question in infection and cancer biology.

The six-year project (2023-2029) is poised to reveal complex and dynamic interactions between genomic, epitranscriptomic and phenotypic adaptation of these important parasites, and the role of stress-adapted ribosomes and non-coding RNAs – especially anti-sense regulators – that compensate for detrimental gene dosage changes. The scientists will further examine whether the parasite has the capacity to predict and prepare in advance to changes in environmental conditions and the switch between its hosts. The study of pathogen evolution within a mammalian host will provide an innovative framework for the discovery of complex biomarker candidates linked to Leishmania virulence and drug resistance. Exploiting genome instability for adaptation is common to other diseases-causing microbes and cancer. This ERC Synergy grant will thus deliver a blueprint to study how chaotic genome instability is harnessed for adaptation and to escape unfavorable environmental conditions.
