本文讨论了通过DNA纳米颗粒展示HIV抗原eOD-GT8,以聚焦抗体反应并减少对支架的竞争性反应,为HIV疫苗设计提供新思路。
原文开头
The HIV antigen eOD-GT8 is engineered to bind strongly to B cell receptors that can mature and promote broad protection to HIV. However, eOD-GT8 is poor at activating B cell responses on its own (left). Displaying 60 copies of eOD-GT8 on a protein nanoparticle enhances B cell activation but also induces competing responses to the protein scaffold (middle). Displaying 30 copies of eOD-GT8 on a DNA nanoparticle focuses antibody responses toward the HIV antigen (right). Subsequent immunizations will aim to guide B cells to mature and express broadly neutralizing antibodies against HIV. …
