Correlation of the Gut Microbiota and Antitumor Immune Responses Induced by a Human Papillomavirus Therapeutic Vaccine
Human papillomavirus (HPV) is the most common sexually
transmitted
pathogen worldwide and the major risk factor for cervical cancer.
According to our previous study, antitumor immune responses induced
by a therapeutic vaccine based on HPV E7 peptide are highly variable
among individuals. Many studies have demonstrated that the discrepancy
in the gut microbiota is an important factor in the development and
regulation of the immune system. Therefore, we performed a systematic
comparative analysis of gut microbiota in two groups of mice with
significant differences in antitumor effects induced by the vaccine,
as well as the correlation between immune cells and gut microbiota.
We divided the mice into group A, in which the tumor continued growing,
and group B, in which the tumor volume was significantly reduced.
In group B mice, the vaccination induced a stronger antitumor activity
with significantly enhanced IFN-γ-producing CD4+ and CD8+ T
lymphocytes, as well as decreased immunosuppressive cells. A detailed
gut microbiota analysis revealed a positive Spearman correlation between
the percentage of CD8+ T cells and the relative abundance of Corynebacteriales, Parabacteroides, and Bacteroides_sp. Furthermore,
the percentage of CD4+ and CD8+ T cells negatively correlated with
the abundance of Proteobacteria and Bilophila. By contrast, the abundance of Proteobacteria, Desulfovibrio, and Bilophila positively correlated
with the percentage of myeloid-derived suppressor cells (MDSCs), regulatory
T cells (Tregs), and type 2-polarized tumor-associated macrophages
(M2-TAMs). Overall, the composition of gut microbiota is related to
vaccine-induced antitumor effects, and there is a correlation between
some gut bacteria and vaccine-induced immune responses
