Study on the progress of HIV typing methods / 上海预防医学

ABSTRACT

As a retrovirus with high recombination and mutation rate， HIV targets CD4+ T lymphocytes， causing damage to the body's immune system and eventually leading to severe immune function defects. Different subtypes of the HIV virus exhibit significant sequence differences in their structural and regulatory genes， and this diversity is closely related to etiology， transmission， diagnosis， drug therapy， disease progression， and vaccine development. As a country with the largest number of HIV subtypes， rapid and accurate typing of the HIV virus holds great significance for China's efforts in disease prevention and control. This study provides a comprehensive reveiw of domestic and international HIV genotyping methods， and summarizes the clinical significance of different subtypes in order to provide reference for further research.
