First person – Aarren Mannion

First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Aarren Mannion is first author on ‘ Tumour cell CD99 regulates transendothelial migration via CDC42 and actin remodelling’, published in JCS. Aarren conducted the research described in this article while a PhD student in the labs of Professor Pam Jones and Professor Graham Cook at the Leeds Institute for Medical Research, University of Leeds School of Medicine, Leeds, UK. He is now a postdoc in the lab of Professor Lars Holmgren at the Karolinska Institutet, Stockholm, Sweden, investigating the role of a signalling axis between the scaffold protein AmotL2 and YAP in endothelial cell mechanotransduction.
