3 Key Takeaways
Plain English Summary- 01Core Finding
High-dose MIC therapy during active diseases showed no additional benefit.
- 02Study Evidence
Tested in a animal models (25 patients) at the preclinical stage.
- 03Practical Meaning
Early laboratory or animal model findings — human trials are still needed to confirm safety and benefit.
What This Means for You
Our clinically applicable cell therapy approach has the potential to control lupus nephritis by specifically dampening deleterious autoimmune responses.
The Discovery
To investigate the efficacy (real-world effectiveness in the trial) of MIC therapy in lupus nephritis, splenocytes from syngeneic NZB/W F1 (BWF1) donor mice were incubated with mitomycin C, and then into BWF1 recipients at 25 weeks of age. Animals were followed for another five weeks to assess disease progression by histological, flow cytometric, and serological parameters. An in vitro phagocytosis assay was conducted to determine the clearance of MIC from 25 patients with lupus and from matched healthy individuals by autologous macrophages. In BWF1 mice, MIC therapy reduced the clinical burden of lupus nephritis disease progression with lower protein excretion and lower serum creatinine levels in the standard-dose compared to the control group. High-dose MIC therapy during active diseases showed no additional benefit. More than a clinically meaningful level of animals had dense lymphocytic aggregates close to the kidney pelvis. These tertiary lymphoid structures differed between MIC-treated animals and controls, with a loss of organization, loss of separation of B-cell and T-cell areas and disintegration of germinal centers after MIC treatment. In the peripheral blood, MIC-treated animals had higher numbers of CD19 + CD5 + CD1d high regulatory-like B lymphocytes. Although MIC treatment was beneficial, higher dosing offered no additional clinical benefit in mice. Macrophages from the patients with lupus efficiently cleared MIC in vitro, ruling out defective clearance as a limiting factor.
