Biochemistry, spectroscopy and structural biology, as well as various forms of microscopy, has resulted in a fairly good understanding of the molecular details of viral and cellular protein recruitment, that is, how the various components of virions bind to one another. However, some parameters of hiv-1 assembly have been challenging to define.
Viruses are faced with a tricky problem: they need to get inside cells, but cells are surrounded by a protective membrane. Enveloped viruses like hiv and influenza, which are themselves surrounded by a similar membrane, solve this problem by fusing with the cell membrane.

Lentiviruses possess a number of accessory genes in addition to the gag, pol, and env genes common to all retroviruses. Human immunodeficiency virus type 1 (hiv-1), the lentivirus most commonly associated with the acquired immunodeficiency syndrome, carries six accessory genes that are required either for full viral replication capacity or for pathogenicity.
The primary focus of my laboratory is development of a vaccine against human immunodeficiency virus (hiv-1), the virus that causes aids. In connection with this research, we characterize biochemical and immunological properties of viral envelope glycoprotein, develop and evaluate novel vaccine vectors, and examine virus-host interactions at various levels.
The genetic material of hiv, an rna molecule 9 kilobases in length, contains 9 different genes encoding 15 proteins.
Reverse transcription, an essential event in the hiv-1 life cycle, requires deoxynucleotide triphosphates (dntps) to fuel dna synthesis, thus requiring penetration of dntps into the viral capsid. The central cavity of the capsid protein (ca) hexamer reveals itself as a plausible channel that allows the passage of dntps into assembled capsids.
The vif protein of hiv-1 allows virus replication by degrading several members of the host-encoded apobec3 family of dna cytosine deaminases. Polymorphisms in both host apobec3 genes and the viral vif gene have the potential to impact the extent of virus replication among individuals.
