Molecular Determinants Of Trim5Α Restriction And Recruitment Of Autophagic Effectors, Sabrina Imam
Dissertations
TRIM5α is an anti-viral restriction factor that inhibits the lifecycle of retroviruses. TRIM5α binds to and forms a hexameric lattice around the retroviral capsid, thereby initiating its antiviral activities, which include: (1) inhibition of viral infection; (2) inhibition of viral reverse transcription; (3) disassembly of the capsid; and (4), activation of innate signaling pathways. The formation of this assembly also activates the E3 ubiquitin ligase function of TRIM5α. Ubiquitin modification is associated with directing substrates to particular cellular pathways. We and others have shown that TRIM5α cytoplasmic bodies colocalize with proteins involved in the autophagy pathway, and we hypothesized that …

Vaccination is historically the most effective tool for preventing infectious disease but current vaccine strategies fail to generate robust immunity to major infectious diseases such as HIV and malaria. Therefore, newer vaccine approaches are needed. Vaccines generated from viral, adenovirus based, vectors (AdVs) have proven highly immunogenic in multiple disease models. However, the clinical use of many AdVs is limited by the presence of pre-existing antibodies in human populations, which prevent expression of antigenic genes during immunization with AdVs based on common adenovirus (Ad) serotypes, such as HAdV-5C. Immunization with rare serotype based AdVs, such as HAdV-28D, are not affected …
