An exceptional array of structural biologists, cell biologists, virologists and other researchers gathered at NIH late last month to discuss achievements, applications and future directions in AIDS-related structural biology. The group was attending the 25th Annual Meeting of the Groups Studying the Structures of AIDS-Related Systems and Their Application to Targeted Drug Design.

I was extraordinarily impressed by the quality of the science, the passion with which it was presented and the interactive culture of the community.

The meeting began with a keynote address by Steve Harrison of Harvard Medical School. He provided valuable historical perspective and then outlined major challenges facing the field. Two days later, the event concluded with a provocative talk by Manuel Navia of Oxford Bioscience Partners about the economics of bringing new lead compounds through the drug development pipeline.

In between were sessions on the HIV life cycle, HIV host-pathogen interactions, imaging, latency, viral host recognition and structure-based drug design and resistance. There were also lively poster sessions showcasing more than 70 projects.

Approximately 2.8% of the NIGMS budget supports research related to AIDS, which includes individual grants, program projects, centers and institutional training grants.

A major focus of our current AIDS-related structural biology efforts is three P50 Centers for the Determination of Structures of HIV/Host Complexes. With cofunding from the National Institute of Allergy and Infectious Diseases, we support the Center for HIV Protein Interactions Exit icon at the University of Pittsburgh; the Center for the Structural Biology of Cellular Host Elements in Egress, Trafficking, and Assembly of HIV Exit icon at the University of Utah; and the HIV Accessory and Regulatory Complexes Exit icon Center at the University of California, San Francisco. These centers use a comprehensive, collaborative approach that engages the larger biological community involved in HIV-cell complex research.

Because the funding initiative for the P50 centers expires next year, we solicited feedback on the program from meeting attendees. We also asked them about emerging scientific opportunities in the field and the best way to move forward. We welcome your input on these topics, too. We’ll talk more about future of NIGMS AIDS-related funding opportunity announcements at the May 2011 meeting of the National Advisory General Medical Sciences Council.

Although many scientific questions remain, the 25th anniversary meeting underscored how basic research on the structure of HIV-1 and interacting host proteins has significantly increased our understanding of virus biology and informed structure-based therapeutic approaches.

Registration is now open for the 25th Annual Meeting of the Groups Studying the Structures of AIDS-Related Systems and Their Application to Targeted Drug Design. The meeting will take place March 28-30, 2011, on the NIH campus in Bethesda.

Plenary sessions will cover the HIV life cycle, host-pathogen interactions, imaging, latency, viral host recognition and structure-based drug design and resistance. The first two days will also include afternoon poster sessions and breakout discussion groups on the future of NIGMS AIDS research initiatives.

Principal investigators, postdoctoral fellows and students are welcome to attend. The meeting is free and open to the public, but advance registration is required. If you’d like to submit a poster presentation, please check the speaker box on the meeting registration page and e-mail me.

The focus of NIGMS-supported HIV studies has evolved from determining the structures of AIDS-related proteins and developing structure-based drug design techniques to identifying mechanisms of drug resistance and host proteins related to the HIV life cycle.

During this special anniversary meeting, the community will have an opportunity to reflect on past accomplishments, describe current advances and develop ideas for future NIGMS AIDS-related funding opportunities. Please visit the meeting Web site for more details about the agenda and confirmed speakers.

We hope to see you in March!

Cell Biology Celebration

The American Society for Cell Biology 50th Annual MeetingCell biologists, including many of our funded investigators and a few of us from NIGMS, were in a celebratory mood as the 50th Annual Meeting of the American Society for Cell Biology Exit icon kicked off December 11 at the Philadelphia Convention Center. The keynote symposium began with Gary Borisy’s description of the first ASCB meeting, when Hans Ris described his then-heretical finding that chloroplasts contain DNA. For more details about the genesis and early years of the ASCB, check out John Fleishman’s article, A Place of Our Own, in the December 2010 ASCB Newsletter Exit icon.

An exciting addition to this year’s meeting was the science discussion table format. Eminent researchers sat at tables for an hour at the beginning of each poster session and took questions from relative newcomers to the field. I stopped by to say hello to some of the NIGMS-supported investigators in my grant portfolio, but each table was crowded with graduate students and postdocs eager to discuss science and seek advice from their fields’ leaders. Two thoughts came to mind as I watched the scene unfold: I wish that there had been these tables when I was a young scientist, and I hope this format becomes a regular feature of the ASCB meeting.

While science is the major focus of the ASCB meeting, education, mentoring and career development also are important features. A number of education workshops focused on topics such as pedagogy, science literacy and online teaching resources. Women in Cell Biology-sponsored events focused on careers, mentoring and managing life as a scientist. In addition, NIH program and review staff answered questions about the grant process. I was one of them, and my favorite part was talking to postdocs and investigators I know from phone calls and e-mail exchanges.

I saw a number of outstanding talks and posters at the meeting, and to say that there is not enough room here to mention them all is an understatement. I was particularly intrigued by presentations from Ron Vale’s lab at University of California, San Francisco, on the cytoplasmic dynein motor domain at 6 Å resolution and from Tom Schwarz at Harvard Medical School on identifying a role for Parkinson’s disease-associated proteins in the regulation of mitochondrial transport within axons. As someone interested in intracellular transport, both presentations offered answers to long-standing problems in cell biology and provided a launching pad for testing new ideas about how organelles move to specific cellular destinations.

I’m already looking forward to the 2011 meeting in Denver.

ASCB Meeting: It’s an Exciting Time for Cell Biology

ASCB ProgramLast week, the American Society for Cell Biology held its 49th annual meeting Exit icon in San Diego. There were thousands of attendees, including many of our funded investigators as well as a few of us from NIGMS. As a new program director, I enjoyed meeting many of the grantees and applicants I’ve talked to on the phone or by e-mail. I met a few others, too, who stopped by the NIGMS booth to get information on funding opportunities.

I can’t even begin to come up with an exhaustive list of all highlights from the 5-day program, so I will share just a few.

I was most excited about how discoveries made using “simple” organisms, such as yeast and unicellular algae, are informing models of human disease in new ways. For example, studies of centriole biogenesis and cilia formation in invertebrates have provided a mechanistic understanding of human ciliopathic disorders such as Bardet-Biedl syndrome. Interestingly, the relationship between human disorders and basic research is a two-way street: By doing a genetic analysis of plant and invertebrate orthologs of genes mutated in people with Bardet-Biedl syndrome, researchers have identified an evolutionarily conserved ciliogenesis “toolkit.”

In his keynote symposium talk, Dr. Rudolf Jaenisch presented another way to think about model systems. He discussed the potential of deriving induced pluripotent stem (iPS) cells from patients, causing the cells to differentiate into a certain type or organ system, and then using the differentiated cells to test for patient-specific drug interventions or gene therapy treatments. There are still scientific and technical challenges, such as recreating the progression of disease development and pathology in a culture dish, but I think that using iPS cells to model human disease may revolutionize our understanding of the cellular basis of disease and, in turn, help us learn more about how normal cells work.

The meeting also stressed the importance of science outreach. During a plenary lecture about the role of NIH in supporting basic research, especially in cell biology, NIH Director Dr. Francis Collins also talked about the role of scientists in educating various groups on the intrinsic value and economic impact of scientific research. Dr. Lawrence S. B. Goldstein echoed this sentiment during his acceptance speech for the ASCB Public Service Award by describing how even small efforts, such as explaining the potential of stem cell research to your neighbor, can have a cumulative impact.

I left knowing that this is definitely an exciting time to be a cell biologist, and I’m already looking forward to the 2010 meeting in Philadelphia.
