Scholia has a profile for Sharon R. Lewin (Q37618308).

Sharon Ruth Lewin AO, FRACP, FAHMS is an Australian Infectious Disease physician and researcher, and the inaugural director of The Peter Doherty Institute for Infection and Immunity, a joint venture between the University of Melbourne and the Royal Melbourne Hospital. She leads a multi-disciplinary research team working on mechanisms of HIV latency, clinical trials advancing potential HIV cure strategies and how HIV is affected by co-infections such as Hepatitis B. Lewin has extensive experience in scientific leadership, and is a strong advocate for community engagement and partnership in research.

Research and accomplishments

Lewin began her research career just as highly active antiretroviral treatment emerged as a transformative influence on the lives of people living with HIV. Drawn to study HIV because of its enormous global challenge, along with the complex social issues, complex medicine and potentially transformative science, Lewin's research interests have developed from questions arising during the clinical care of people living with HIV. Detecting, quantifying and potentially reactivating latent HIV is a central theme of Lewin's research, which spans basic virology, cellular immunology and clinical research. Her research laboratory is run together with immunologist and clinician Associate Professor Paul Cameron, with whom she has developed a long-standing collaboration and partnership. Lewin has authored over 250 peer-reviewed publications.[citation needed]

While completing her postdoctoral training with David Ho at the Aaron Diamond AIDS Research Centre, Lewin developed a highly sensitive PCR method to detect unspliced HIV RNA, an early product of viral transcription, in people receiving antiretroviral drugs.[1] Over 20 years later, this method still informs studies of residual HIV replication, HIV latency and viral reactivation. Lewin's laboratory has developed models of HIV latency which are used to further tease out the mechanisms involved, and to assess the impact of latency reversal agents. Lewin's lab has shown that triggering the CCR7 receptor on resting CD4 T cells can induce latency,[2] acting through the activation of the cellular cytoskeleton, particularly actin remodelling.[3] This chemokine-induced latency model has been used in a comprehensive comparison of in vitro models for evaluating latency reversal agents.[4] Lewin's laboratory has also described the role of myeloid dendritic cells[5] and other antigen-presenting cells[6] in establishing HIV latency.

Lewin's team have made contributions to the knowledge of the HIV reservoir during antiretroviral treatment. This includes studies of naive CD4 T cells, where longitudinal and cross-sectional studies have shown that both CD31+ and CD31- naive CD4 T cells contribute to the ongoing HIV reservoir[7] and that HIV DNA is preferentially found in CD4 T cells expressing the chemokine receptors CXCR3 and CCR6.[8] Lewin's group has also studied immune reconstitution after antiretroviral treatment begins, exposing some of the factors associated with faster reconstitution[9] and has demonstrated7 a link between immune reconstitution and variants in the IL-7R gene.[10][11]

Lewin's research has elucidated some of the basic immunology of Hepatitis B infection alone[12] and in co-infection with HIV.[13] Ongoing research is providing a deeper understanding of the clinical consequences of co-infection with Hepatitis B and HIV, both in Australian participants[14][15] and through a long-standing collaboration with Thai researchers.[16][17][18][19]

Lewin's clinical research efforts have focussed on potential HIV cure strategies, particularly those using the epigenetic modifiers including histone deacetylase inhibitors (HDACis).[20][21] In vitro experiments showed that HDACis such as entinostat,[22] metacept-1 and -3[23] could activate latent HIV in primary T cells. Following a sabbatical working with Christine Katlama and Brigitte Autran at the Hopital Pitié-Salpêtrière and Université Pierre et Marie Curie (UPMC), Paris, Lewin began to focus more on moving potential cure strategies into clinical trials.[24] Lewin's lab conducted the first multi-dose proof-of-concept HDACi trial in HIV positive participants, administering vorinostat daily over a 14-day period and assessing safety and impact on HIV transcription and reservoirs.[25] The trial and follow-on study[26] showed that while vorinostat was safe and able to increase HIV transcription in most participants, it did not reduce the HIV reservoir.[25] A dose-escalation study conducted in Melbourne, Australia and San Francisco, California, USA of the anti-alcohol compound Disulfiram also showed the ability to increase levels of cell-associated unspliced HIV RNA.[27] Both vorinostat and Disulfiram are now being investigated as part of a combination approach to latency activation ('kick' or 'tickle') followed by a second intervention to remove cells harbouring reactivated virus ('kill' or 'tease').

Lewin has been invited to present at international conferences, and gave the opening plenary at the International AIDS Conference in Vienna in 2010 to an audience of over 10,000. Lewin is also an international scientific advocate, was local co-chair for the International AIDS Conference (AIDS 2014) in Melbourne, a member of WHO and UNAIDS strategic advisory groups and lead co-author of the 2016 International AIDS Society global scientific strategy to achieve an HIV cure.[28] Lewin is a founding council member of the Academy of Health and Medical Sciences, elected member of the Governing Council of the International AIDS Society representing the Asia Pacific region, member of the council of the National Health and Medical Research Council (NHMRC) of Australia and chairs the Health Translation Advisory Committee. She chairs the Ministerial Advisory Committee on Blood Borne Viruses and Sexually Transmitted Infections, the peak advisory group to the Minister of Health of Australia.
