Leor Weinberger's lab studies fundamental processes of viral biology to develop innovative therapies against HIV. The lab discovered a viral program that allows HIV to grow in some cells and remain dormant in others, and a new class of molecules that manipulate this program in infected individuals. The group developed and pioneered the concept of Therapeutic Interfering Particles (TIPs), single-administration, resistance-proof therapeutics that could treat HIV in resource-limited settings such as sub-Saharan Africa and in injection drug users. The group also develops novel therapies for herpes simplex and cytomegalovirus, the leading cause of birth defects and transplant failures.
Areas of Expertise
Weinberger and his team are known for discovering HIV’s latency “circuit”. HIV latency is a viral dormant state and the chief barrier to an HIV cure. Weinberger’s lab characterized the molecular mechanisms regulating HIV stochastic fluctuations (“noise”) and overturned dogma to show that HIV evolved circuitry to control latency by manipulating noise. These studies led to the lab’s discovery of a new class of molecules (noise enhancers), and of gene circuits in herpesviruses that are being exploited as a new class of antiviral targets.
The lab couples computational and experimental approaches, including quantitative, single-cell and single-molecule microscopy and mathematical modeling. An exciting illustration is the team’s recent effort to engineer resistance-proof, single-administration therapies for HIV. These therapies would benefit the highest-risk populations who most need therapy, and are aimed specifically at resource-poor settings such as sub-Saharan Africa or at people who inject drugs.
