Although we did not observe marked differences in percentages of DC populations among HD, and BC patients pre- and post-treatment, after three doses of chemotherapy we found a substantial recovery of CD83 expression and production of IL-12 in response to a cocktail of cytokines used by Mailliard et al., [12] to derive type I alpha DCs in situ [11]. The gene discussed is CD83; the disease is Huntington disease.
