Contrasts in pathomechanisms and treatment targets between adult and paediatric inflammatory myositis
👁🗨Summary of Mechanisms
👁🗨DM/JDM👉🏻 CD4 and TH17 mediated
👁🗨 Both Inflammatory and non inflammatory factors contribute
#EULAR2022
👁🗨 Type I,II IFN sig
👉🏻 DM/JDM>>ASS/PM>IBM>IMNM
👉🏻 Mi2/TIF/MDA5>>Jo1>>SRP/HMCGR
👁🗨⬆️INF levels 👉🏻⬆️ disease activity
👁🗨pDC and mDC mediated
👁🗨Mediate Muscle atrophy(perifasicular) and Capillary loss
