RESUMO
@#Acquired immune deficiency syndrome,or AIDS,has been a major infectious disease that troubles the public health in a global scale. Human immunodeficiency virus type 1(HIV-1)is the causative reagent responsible for AIDS development. Even though the highly active anti-retroviral therapy(HAART,or the cocktail therapy)that has been widely applied could effectively suppress the infection and replication of HIV-1,the infected people suffer from other related diseases,such as the HIV-associated neurocognitive disorder(HAND). This paper mainly focused on the function of an important regulatory protein of HIV-1,trans-activator of transcription(Tat),and its correlation with HIV-1 replication and HAND development,so as to clarify the importance of developing anti-AIDS drugs targeting Tat protein
