Background:

  • Human Immunodeficiency Virus type 1 (HIV-1) vaccine development remains a critical area of AIDS research.
  • The HIV-1 envelope glycoprotein (Env) is the primary target for neutralizing antibodies as it mediates viral entry into host cells.
  • Achieving a native-like HIV-1 Env trimer is essential for eliciting a robust immune response.

Purpose of the Study:

  • To review and compare various strategies for designing stable and high-yield HIV-1 Env trimers.
  • To provide insights into the advantages and disadvantages of different Env trimer design approaches.
  • To offer guidance for future HIV-1 immunogen design based on current research and experimental work.

Main Methods:

  • Review of recent advancements in HIV-1 Env trimer design strategies.
  • Comparison of methodologies including SOSIP, NFL2P, and UFO.
  • Analysis of strategies aimed at improving Env trimer quantity and stability.

Main Results:

  • Breakthroughs in Env trimer research have led to the development of strategies like SOSIP, NFL2P, and UFO.
  • Improved quantity and stability of Env trimers are key to generating native-like structures.
  • These native-like trimers are crucial for eliciting strong neutralizing antibody responses in animal models.

Conclusions:

  • The choice of Env trimer design strategy significantly impacts immunogen efficacy.
