Étude du contrôle de la dynamique des microtubules de KANK1 dans les neurones humains dérivés d’iPSC (en anglais)

Stage Master 2 - Equipe "Dynamique et structure du neurocytosquelette"



The main objective of this project is to understand how the protein KANK1 controls the microtubule dynamics in human iPSC-derived neurons. To this end, the student will combine several approaches including live microscopy imaging, micropatterning and biochemistry on cortical neurons derived from human iPSC.


Amyotrophic lateral sclerosis (ALS) represents a rapidly progressing neurodegenerative disease and is characterized by a degeneration of the motor neurons. A recent study which combined machine learning approach with data from induced pluripotent stem cells-derived motor neurons from patient with ALS, revealed that KANK1 was associated with the highest number of ALS-associated genetic variants. However, the role of KANK1 in neurons still remains to elucidate. KANK1 is a protein known to link microtubule tips with the major component of integrin-mediated focal adhesion, talin. Our hypothesis is that KANK1 interaction with microtubules in the vicinity of integrin adhesions is critical and an impairment of these interactions can affect the balance between stable and dynamic microtubules, found altered in ALS. By combining a broad range of approaches, the student will (i) characterize the integrin-mediated adhesions of iPSC-derived neurons and (ii) will address in this context, the role of KANK1 in the microtubule dynamics.
