Dr. Waheed’s research is focused on understanding the role of host factors in human immunodeficiency virus type 1 (HIV-1) particle assembly and release. Several host factors are involved in late stages of the retroviral replication cycle. Understanding the role that cellular proteins and lipids play in HIV-1 assembly and release could lead to the design of novel drugs that target and disrupt these interactions, resulting in inefficient virus release and a block to virus replication.

Several cellular restriction factors inhibit HIV-1 replication both at early and late stages. To counteract these restriction factors, viruses have evolved antagonistic accessory proteins. We are interested in identifying cellular proteins involved in counteraction of host-restriction factors by viral proteins.
