Distinct human immunodeficiency virus type 1 subtype A virus circulating in West Africa: sub-subtype A3.

abstract：:The human immunodeficiency virus type 1 (HIV-1) Tat protein, which is essential for HIV gene expression and viral replication, is known to mediate pleiotropic effects on various cell functions. For instance, Tat protein is able to regulate the rate of transcription of host cellular genes and to interact with the signa...
