And, there cellular subtypes had been identified among myeloid cells from JIA and cHC by evaluating the expression of CD1C, FCER1A, CD68, LYZ, CD14, FCGR3A (Figures 1D, E), as CD14 Mono (CD14+ Monocytes), Inter Mono (Inter Monocytes), CD16 Mono (CD16+ Monocytes) and DC (dendritic cells). Here, FCER1A is linked to juvenile idiopathic arthritis.
