Important cytokines in SLE: the major secreting cells and possible clinical applications.

CytokinesMajor secreting cellsPossible Clinical applications

IL-6Monocytes (i) Tocilizumab (Anti-IL6R Ab) showed good efficacy and tolerability in phase 1 trial for mild to moderate lupus [25]
Fibroblasts 
Endothelial cells

IL-10Monocytes  (ii) Anti-IL10 monoclonal antibody improve cutaneous lesions, joint symptoms and SLEDAI in lupus patients [34]
Lymphocytes

IL-17Lymphocytes (Th-17 subset) (iii) Still under investigation

BLysMonocytes  (iv) Belimumab (monoclonal Ab against soluble BLys) showed reduction in CD 2 0 + B cells but no significant improvement in disease activity [65]
Macrophages 
Dendritic cells  (v) Atacicept (fusion protein against TACI receptor) showed clinical improvement for moderate lupus but phase II trial suspended due to high infective risk
Activated neutrophils

Type 1 Interferon (IFN)Plasmacytoid dendritic cells (PDC) (vi) IFN regulated chemokines used in monitoring of disease activity and organ damage [90, 91]
(vii) Anti-IFN monoclonal antibody showed improvement in disease activity in phase I trial [92]

TNF-alphaMacrophages   (viii) Infliximab (Anti-TNFα) improved joint symptoms and proteinuria in lupus patients with moderate activity [103]
Dendritic cells
   (ix) Infliximab (Anti-TNFα) resulted in sustained remission in Class IV lupus nephritis patients who failed to achieve remission with steroid/MMF/cyclosporine [104]
