title = "Si-doping increases the adjuvant activity of hydroxyapatite nanorods",
abstract = " Recombinant protein-based vaccines generally show limited immunogenicity and need adjuvants to achieve robust immune responses. Herein, to combine the excellent biocompatibility of hydroxyapatite (HA) and exciting adjuvant activity of silica, Si-doped HA nanorods with Si/P molar ratio from 0 to 0.65 were hydrothermally synthesized and evaluated as immunoadjuvants. Si-doping decreases the size and increases the BET surface area of the nanorods. Si-doping in HA nanorods increases the in vitro adjuvant activity, including CD11c + CD86 + expression and cytokine secretion of bone marrow derived dendritic cells (BMDCs). Moreover, Si-doping in HA increases the ex vivo adjuvant activity as shown by the increase in both Th1 and Th2 cytokines secretion. Si-doped HA nanorods are promising as a new immunoadjuvant.",
