Fig. 4From: Multiple antigen-engineered DC vaccines with or without IFNα to promote antitumor immunity in melanomaCirculating suppressor cell frequencies. The frequencies of (a) Treg and subsets of myeloid (b, c) MDSC are shown (n = 35 patients). The left side of each panel shows the difference between baseline and d = 43 post DC vaccines. The right side of each panel shows the change between d43 and d89 for each trial arm. Dotted lines represent median HD values (n = 35). Two examples of significant correlations between MDSC frequencies and patient development of vaccine antigen-specific T cell responses are shown (d)Back to article page
