Molecular Characterization Of Hiv Tat Protein Functional Properties
The HIV-1 Tat protein plays an essential role in HIV replication and has successfully pased phase II clinical trials as therapeutic vaccine in HIV-infected subjects. Besides possessing important antigenic features, the Tat protein exerts immunomodulatory activities and plays a role in immune dysregulation during HIV infection. Accordingly, the main goal of the project is the functional and molecular characterization of Tat activity on T cells. The expected results will lead to new knowledge on the role of Tat in the immune dysregulation of HIV+ subjects and provide new insights into the possibility of employing Tat as a general effective immune modulator.
Goals
- Characterization of Tat activity on T cells functions
- Molecular characterization of Tat effects in T cells
- Characterization of Tat as an immune modulator of immune responses against other antigens
Instruments and Methods
