Table I. Humoral immune response against nontargeted tumor antigens after treatment with Sipuleucel-T and its association with improved clinical outcome. Polarization of a type 1 anti-tumor immune response in the context of a strong tumor antigen results in the regression of the mammary adenocarcinoma, 4T1. In the viral literature, the dependence of future responses on past ones to similar antigens is well documented [ 43444546 ], and there are recent reports suggesting that preexisting immunity not only occurs, but is common; many healthy adults have memory T cells reactive to peptides from viruses they have never encountered [ 47 ]. Additional file 2: Figure S1. Preliminary IgG Peptide Array. In the future, it may be possible to determine this antigenic history and correct gaps in immune surveillance with either personalized cancer vaccines or generalized complex vaccines like the autophagosome-enriched vaccine studied here. The correlations between vaccine-induced T cell responses and antigen-specific IgG antibody signals observed in this study suggest that IgG may be one biomarker to observe such relationships between past immunologic history and future or ongoing anti-tumor immunity. To analyze the patterns of the IgM antibodies, a clustering algorithm was applied. In preliminary studies, the average intensity values from all initial 20 arrays were normalized simultaneously using an interquartile range transformation performed using BRB-ArrayTools v4.

    Nat Biotechnol. Walter J. Our IgG array data demonstrated that many of the strongest vaccine-induced antibody responses to 4T1 peptides could be detected, albeit at lower levels, in naive animals Additional File 2 : Fig. Afentoulis 1Christopher Dubay 1Larry L. The majority of research has focused on establishing cancer biomarkers using IgG for the diagnosis or treatment of breast cancer, while IgM autoantibodies have been insufficiently studied despite their relevance in the early recognition of tumor antigens 12
