Abstract

This work was supported by the Research Committee from Hospital Universitario de Galdakao. IR-L is supported by a research grant from Gobierno Vasco – Eusko Jaurlaritza (grant number 2020111061) and Biobizkaia (BCB/I/LIB/22/008). The apheresis column and Promonitor kit were kindly provided by Adacyte and Progenika Biopharma, neither of them were involved on study design nor interpretation of the results.
