Shinde et al.35demonstrated that while the differences in expression of HLA‐DR, CD80, CD86, and other phenotypic markers between HD‐DCs and multiple myeloma (MM)‐DCs did not reach statistical significance, patients with multiple myeloma had impaired Mo‐DC functioning, which may explain why DC vaccinations are ineffective. This evidence concerns the gene CD80 and Miyoshi myopathy.
