Contributing pathways

Ref

Systemic lupus erythematosus

DNMT1

CD4 T cells

NO

NO

MBD 2 ultimately causes hypomethylation of the relevant genes by affecting DNMT 1

[61, 62]

Sjögren syndrome

NO

B cells

NO

NO

MBD 2 affects B cell demethylation around the salivary glands

[70, 71]

Type 1 diabetes

STAT1

Th1 cells

MBD2−/−

The IFN- γ, GM-CSF, and TN-F- α levels increased significantly

MBD 2 maintains the homeostasis of the Th 1 program by binding to the methylated CpG DNA within the Stat 1 promoter

[73, 75]

Rheumatoid arthritis and multiple sclerosis

NO

NO

NO

NO

Patients presented global DNA hypomethylation compared to healthy individuals, along with elevated mRNA expression levels of MBD 2 and DNMT 1

[76]

Ulcerative colitis and lupus nephritis

IFN-γR, STAT1, and IFI35

Macrophage

MBD2−/−

IFN- γ, the activation of the NF- κ B-related pathway

MBD 2 controls the expression of molecules of inflammation-related pathways such as IFN- γ R, STAT 1, and IFI 35 and NF- κ B

[79, 80]

Idiopathic pulmonary fibrosis

Erdr1

Macrophage

MBD2−/−

Prevent fibroblast differentiation into myofibroblasts

MBD 2 selectively binds to the methylated CpG sites within the Erdr 1 promoter
