In our previous study of the TBNK subset detection in SLE children (c-SLE), we found that the numbers of CD8+ T cells and CD19+ B cells in the c-SLE with hypocalcemia were higher than those in the c-SLE with normal serum calcium concentration (Figure S1A), which was not affected by whether GCs were applied. This evidence concerns the gene CD8A and systemic lupus erythematosus.
