Tofacitinib inhibits monocyte-derived dendritic cells differentiation in rheumatoid and psoriatic arthritis: a novel mechanism of action 

Marzaioli, V.

Hospital Professional News Ireland 2020 Oct ;77 (Page 36)

“In this study we investigated the capacity of monocytes to differentiate into dendritic cells in both Rheumatoid (RA) and Psoriatic arthritic patients (PsA). We observed different morphological and functional profiles between monocytes obtained from RA and PsA patients, with RA monocytes primed to differentiate into DC and exhibiting differentiation and activation markers at earlier time point compared to that of PsA. We further demonstrated a novel mechanism of action for Tofacitinib, a JAK/STAT inhibitor recently approved in the treatment of RA and PsA patients. We demonstrated that Tofacitinib inhibits Mo-DC differentiation in both RA and PsA patients, via the regulation of NOX5 expression and ROS production, giving us further insight into the use of the drug as a successful treatment strategy for IA.”  -Dr. Viviana Marzaioli
