CD14 and Miyoshi myopathy: A significant upregulation of CD84 expression was detected on BM-derived (Figure 1E) and peripheral blood–derived (PB-derived) (Figure 1F) human myeloid CD14+ cells (around 10 times higher) compared with its expression on CD14– cells and CD14+ cells derived from healthy human donors, suggesting that the CD14+ population has a more significant role in MM patients.
