In the original article published, the data we received from our CRO laboratory inadvertently labelled cytokine Tumor Necrosis Factor Ligand 13B (also known as BAFF) as Tumor Necrosis Factor Ligand 13 (also known as APRIL). Therefore, we believed that the data we were reporting in our Figure 3 was for APRIL, when it was actually data for BAFF. Since APRIL and BAFF are members of the same family of proteins, can bind to the same receptors, and are both involved in B cell survival and proliferation, this oversight did not change the conclusions drawn in the manuscript of repository corticotropin injection being associated with B cell immunomodulation.

The original article has been corrected.
