Here, There, and Everywhere: Alpha-Fetoprotein in Cancer Immunotherapy
Volume 2
Alpha-fetoprotein (AFP) delivers nutrients to immature cells in a shuttle-like manner via alpha-fetoprotein receptor (AFPR)-mediated endocytosis. A small subset of immature myeloid-derived suppressor cells (MDSCs) acts as a key regulator of immune tolerance during pregnancy, cancer, and other conditions. MDSCs, low doses of AFP, and AFP-binding ligands can modulate both the innate and adaptive immune responses. MDSCs decrease excessive immune activation, while their depletion can reverse immune suppression. Reduction of..
