The Study of Comparing the Efficacy and Safety of Human Umbilical Cord MSCs and Low-dose IL-2 in the Treatment of LN

Allogeneic MSC transplantation has shown significant efficacy and good safety in the treatment of refractory autoimmune diseases such as lupus nephritis (LN), and has a broad application prospect. One of its mechanisms is that MSCs up-regulates the production of IL-2 and promotes the production of Treg cells. The breakthrough in this technology has brought new hope for patients with autoimmune diseases. Some small sample studies at home and abroad have shown that low-dose IL-2 can be used to treat LN. Recently, the research team found that a single dose of IL-2 showed a longer effect than repeated low-dose MSCs. However, there is still a lack of prospective randomized studies to confirm that the efficacy of allogeneic MSC is better than that of low-dose IL-2. Therefore, carrying out this prospective randomized study will make a real breakthrough in the clinical application of MSC in SLE, and open up a new field for the treatment of SLE for the benefit of mankind.
