By: Published Date: Nov 25 In a November 18, 2014, article in GEN (Genetic Engineering & Biotechnology News), Susanna F. Greer, Ph.D., says microbiology professor Louis Justement, Ph.D., changed her life.

As an undergraduate chemistry major in the 1990s, Greer spent a summer doing biomedical research in Justement’s lab at the University of Texas Medical Branch at Galveston. This initial encounter led Greer to choose a career in research. She is currently associate professor of biology at Georgia State University, specializing in transcriptional and epigenetic regulation of immune response and cancer immunology.

Justement, who chairs the Training and Career Opportunities Subcommittee of the Federation for American Societies for Experimental Biology, continues to change the lives of students here at UAB.

By: Published Date: Nov 21 The lab of Frances Lund, Ph.D., chair of the UAB Department of Microbiology, is looking at a cell-fate step in B cells after they have proliferated. She wants to understand the switch from rapid cell division to a cell that starts to manufacture antibody molecules. The cytokine interferon-gamma (IFN-gamma) has been implicated in that cell-fate decision, which leads to a fork in the road — most of the B cells make a lot of antibody and then die, but others become long-lived antibody-secreting cells that can produce protective antibodies for decades.

The lab of Allan Zajac, Ph.D., associate professor of microbiology at UAB, is looking at CD8 T cells, which can develop into the classic “killer” T cells that can destroy virus-infected cells. A cell-surface adhesion molecule called ICAM seems to direct the type of T cell produced after cell-to-cell interactions — some of the CD8 T cells become killer T cells, and others become long-lived memory T cells. Zajac believes that ICAM limits the amount of IL-2 experienced by some clustered T cells, and this helps produce memory cells rather than killer cells. Zajac has two versions of lymphocytic choriomeningitis virus that differ by only two nucleotides — one causes an acute infection in mice that is quelled in 10 days, while the other, faster-replicating virus gets out of control and exhausts the immune system, and the mice take months to recover.

October 17-19, 2014, microbiology department faculty, and special guests gathered at Alabama’s beautiful Joe Wheeler State Park for the annual microbiology department retreat. This has always been one of our favorite retreat venues because of its convenient (about 2 hours from Birmingham) and beautiful location near Rogersville, Alabama, on Wheeler Lake, a 60 mile long body of water created by Wheeler Dam along the Tennessee River. This year’s retreat was a wonderful opportunity for students, faculty and postdocs to focus on science and to establish new collaborations away from the distractions of everyday life. The weather this year could not have been better. An added treat was the unveiling of the new microbiology department T-shirt during the retreat registration. Images on the shirt were provided by microbiology graduate student Shane Kelly (Bedwell lab) and depicted squamous epithelial cells isolated from the buccal mucosa of the cheek. Shane’s artwork was awarded Judge’s Choice in the 2014 UAB School of Medicine Art Show.

By: Published Date: Oct 20 While doing graduate research in the UAB microbiology department, alumnus Juan Calix, M.D., Ph.D., wrote an F31 grant application that was not only funded, but also selected by NIH as a model application. According to NIH Program Specialist Jen Sacchetti, Calix’s excellent F31 application is posted on the NIH public website as a sample for the extramural researcher community.

“His application mentions the research strength at UAB, and various programs including UAB MSTP,” says Moon Nahm, M.D., Calix’s mentor.

Calix received several awards while studying at UAB, including the 2012 Samuel B. Barker Award for Excellence in Graduate Studies, the most prestigious annual award given to students from the Graduate School.

In 2014, after receiving his MD/PHD at UAB, Calix began a medical internship at Washington University in St. Louis. He is in a special faculty training program where he can do research in the late phase of his residency training and can be an infectious diseases faculty member there.

"I believe that he will soon be a leader in infectious diseases and microbiology,” says Nahm. “Clearly, Juan is a model student for UAB.”

The model F31 application is on the NIH/NIAID website -- http://www.niaid.nih.gov/researchfunding/grant/samples/Pages/F31-Calix.aspx

He was an instructor in the Department of Pediatrics at Harvard’s Children’s Hospital before moving to the Wistar Institute in 2007. He worked for seven years at the Wistar Institute. Hu has received several awards and honors including the ACGT Young Investigator Award.

Hu’s research at UAB will focus on how to induce a primary antibody response like a memory one. “The humoral immune response is one of the two effector arms of the immune system,” explains Hu. “Studies have shown that CD4⁺ T follicular helper (Tfh) cells are essential for long-lived, high affinity antibody responses. Yet the complex regulation that determines the initial development of Tfh cells, their developmental progression in germinal centers (GC), and their fates after an immune response dissolves, is still not fully understood. Recently, my research has shown that transcription factor Foxp1 is a rate-limiting and essential negative regulator of Tfh cell differentiation, drastically affecting GC and antibody responses (Nat. Immunol. 2014).”

 “Usually your initial immune antibody response to an infectious agent takes about a week, and is relatively weak.” Hu says. “Now we have found an important regulatory step that could allow us to induce antibody responses more faster-acting and effective. And in the other way around, we may also be able to significantly dampen the antibody responses that are unwanted in some cases of autoimmune diseases such as lupus.”

Hu’s laboratory is also working to find a way to activate T cells under immunosuppressive circumstance. “Much of our understanding of molecular mechanisms regulating immune responses is centered on pathways and processes that promote cell activation, division and differentiation,” says Hu. “My research has already demonstrated that cell-intrinsic signaling pathways are required to maintain mature T cells in a quiescent state (Nat. Immunol. 2011). If these pathways are disrupted, resting T cells become aberrantly activated even in the absence of antigen challenge. My next step is to identify regulatory genes and pathways that actively restrain T cell activation, and define the roles of such negative regulatory pathways in controlling T cell quiescence, effector responses, memory maintenance, and tumor immunology.”

By: Published Date: May 21 Informative, beneficial, vibrant . . . these three words describe the 2014 Microbiology Faculty Retreat, which was held on Wednesday, May 14th at the Birmingham Botanical Gardens. Dr. Fran Lund, chair of the department says, “The turnout was great, and our discussion sessions were especially good this year.

The faculty retreat is a valuable event that focuses on the two major objectives of the department—scientific research and education. Dr. Louis Justement says that the event “provides a venue for the diverse faculty to share research and ideas regarding ways to improve the department. Basically, the retreat is very valuable because it fosters communication between the faculty and communication is the key to building collaborations and for making the department stronger.”

What began in the late 1990s with only three UAB labs (Briles, Yother and Hollingshead) participating has become a biannual symposium attended by more than 70 attendees from six southeastern research institutions: UAB Wake Forest School of Medicine Mississippi State University University of Georgia University of Mississippi Medical Center Alabama State University	Dr. David Briles speaks with Thelma Tower, a student from Mississippi State University, before her presentation.
Dr. Fikri Avci, University of Georgia	This two-day symposium offers researchers an opportunity to share the latest developments in the field of pneumococcal research. Distinguished speaker for the 2014 event was UAB microbiology alumni, William E. Swords, Ph.D. He discussed his research at Wake Forest School of Medicine, which focuses on understanding host-pathogen interactions that determine persistence vs. clearance in the airways.

By: Published Date: Apr 07 Congratulations to Dr. Jamil Saad for receiving the 2014 Provost's Award for Faculty Excellence in Academic Engagement and Global Citizenship. He is one of only four faculty members campus-wide to receive this honor. The award recognizes UAB faculty members for engaging undergraduate students in research, creative activities, service learning, and study abroad activities. Awards will be presented at the UAB Expo Award ceremony Friday, April 11, 2014.

By: Published Date: Apr 01 On March 5, 2014, Drs. Lou Justement (Microbiology), Beth Brown (Epidemiology and Microbiology) and John Chatham (Pathology) travelled to Washington D.C., in between snow storms, to participate in the 2014 Federation of American Societies for Experimental Biology (FASEB) Capitol Hill Day visit. They were accompanied by Joel M. Widder from the Oldaker Group who served as the group liaison.

The FASEB Capitol Hill Day is an annual event during which members of the FASEB Board and Science Policy Committee go to Capitol Hill to meet with their legislators to request increased support for the NIH and NSF. Drs. Justement, Brown and Chatham met with staff from Senators Shelby and Sessions offices as well as Representative Sewell’s office. They also had an opportunity to meet directly with Representative Bachus to discuss the important role that UAB plays in the economic growth of Alabama and how its activities foster improved health for the state. Representative Bachus was very supportive as were all of the legislators that they spoke with.

A summary of the FASEB Capitol Hill Day visit for 2014 prepared by Jennifer Zeitzer of FASEB can be viewed here.

Activities such as these are important to raise awareness of the effects that decreased support for NIH and NSF have on the future of biomedical research in the US. If anyone has an interest in speaking out on behalf of biomedical research, they should contact Drs. Justement, Brown or Chatham for advice. Additionally, most professional societies have active public affairs offices that are willing to arrange visits to Capitol Hill. Remember, you can take the initiative to contact your legislators at any time by email or phone, and be sure to respond to requests to contact your legislator sent out by FASEB or other societies. The more often Congressional legislators hear from the scientific community, the more likely they will be to appreciate the importance of the NIH and NSF.

By: Published Date: Mar 21 Congratulations to Bliss Chang, an undergraduate student in Dr. Jamil Saad’s lab, who was named a 2014 Goldwater Scholar by the Barry M. Goldwater Scholarship in Excellence in Education Foundation.

Chang, a Biochemistry and Biology major, plans to pursue an M.D./Ph.D. that will allow him to enter academic medicine and teach at a leading medical research university. His work in the Saad lab involves further elucidating the structural basis for Fas-mediated apoptosis and investigating the role of a point mutation in the Fas protein that may reveal the mechanism of inhibition for the Fas pathway.

The Barry Goldwater Scholarship and Excellence in Education Program was established by Congress in 1986 to honor Senator Barry Goldwater, who served his country for 56 years as a soldier and statesman, including 30 years of service in the U.S. Senate. The purpose of the Foundation is to provide a continuing source of highly qualified scientists, mathematicians, and engineers by awarding scholarships to college students who intend to pursue research careers in these fields.

By: Published Date: Mar 12 Dr. Amy Weinmann joined the microbiology department in February 2014.Growing up in Minnesota, Amy Weinmann attended the University of Minnesota, Morris, where she received a B.A. in biology in 1995. An undergraduate summer project at the Mayo Clinic gave her an appetite for research and set her on a path to crisscross the United States. She moved from Minnesota to California where she received her Ph.D. from the University of California, Los Angeles. She moved from California to Wisconsin where she completed a postdoctoral fellowship at the University of Wisconsin, Madison, and then she moved from Wisconsin to Seattle, Washington, and joined the faculty at the University of Washington Department of Immunology. Now, ten years later, she has made her way to Alabama.

Currently, she is working on the mechanisms by which lineage-specifying transcription factors regulate cell fate decisions in development. “A major focus of the research in my lab is on the T-box and BTB-ZF transcription factor families, which are required to promote cellular transitions in numerous developmental systems, ranging from early embryogenesis to immune cell fate. We are also interested in defining the mechanisms by which epigenetic patterns are established in a cell-type and activation-state specific manner. Collectively, our mechanistic studies will provide new insight into many human diseases that are associated with dysregulation of these pathways, including a major emphasis on blood cancers, autoimmunity, and birth defects.”

During this time of economic challenges, Weinmann takes her job as mentor seriously. She says that it is easy to get discouraged when funding is so limited, but a person must not accept the word can’t. “Science is do-able,” she says. “Passion comes from within. Nobody can take your passion away from you.” She enjoys watching students learn how to drive their own science. “Early on, it’s much more hands-on, but eventually it starts to flip and by the end, the student knows way more than I do. It’s a proud moment when they’re on their own.”

In her spare time, Weinmann follows professional sports (especially the Minnesota Vikings), and she herself can spike a mean volleyball, having played volleyball in high school and college. She says, “the mental discipline of sports fits well with science. It’s always a work in progress; you should be proud of what you’ve accomplished, but at the same time strive to do better and learn more.”

By: Published Date: Mar 12 Dr. Mengxi Jiang joined the microbiology department in January 2014.Growing up in Shanghai, China, Mengxi Jiang attended Fudan University where she received her undergraduate degree in 2001. Later that year, she moved to the United States and began research in bacteriology at the University of Michigan. When she received her Ph.D., she took a different direction and accepted a postdoctoral position at University of Michigan in the area of virology. “While working toward my Ph.D., I became more interested in the interplay of the host and pathogen. This led me into the field of virology,” says Jiang.

In 2012, Jiang became a research investigator at the University of Michigan, where she worked two years on the host-pathogen interactions of a human DNA tumor virus, BK polyomavirus (BKPyV). Now, as assistant professor in the microbiology department at UAB, she continues to search for a better understanding of the BKPyV life cycle to aid in the design of novel, more efficient anti-viral strategies.

“BKPyV infection is ubiquitous in the human population and occurs during early childhood,” says Jiang. “Primary infection with BKPyV is followed by dissemination to the kidney and urinary tract, in particular to kidney tubule epithelial cells and urinary tract epithelial cells, where the virus establishes a lifelong persistent infection. This infection remains asymptomatic in immunocompetent individuals, but under conditions of immunosuppression, BKPyV can undergo reactivation resulting in viral shedding in the urine and may eventually lead to severe diseases such as polyomavirus-associated nephropathy (PVAN) in renal transplant patients and hemorrhagic cystitis in bone marrow transplant recipients.”

Jiang says that no specific antiviral drugs for BKPyV infection are currently available, although the incidence of BKPyVrelated disease has greatly increased in the last few years. The immune components that are involved in controlling BKV persistence and reactivation are not well defined. As a new assistant professor, Jiang is looking to fill several positions in her lab. She enjoys sharing her excitement for research with students just entering the field. “It is important for students to learn how to do science, to think critically, and to establish their independence,” says Jiang.

By: Published Date: Feb 28 On February 7, 2014, the University of Alabama System Board of Trustees appointed John F. Kearney, Ph.D., distinguished professor in the UAB School of Medicine Department of Microbiology. This is one of the University’s highest honors bestowed on faculty by the Board.

Kearney’s work has brought worldwide recognition to UAB. He is an internationally recognized expert in monoclonal antibodies and their source: immune cells known as B cells that produce the antibodies necessary to fight off infections and other immune threats.

Kearney came to UAB as a postdoctoral fellow in 1974 and joined the microbiology faculty in 1977. In addition to his primary faculty appointment in the microbiology department, Kearney holds several other appointments at UAB including senior scientist in the UAB Comprehensive Cancer Center and UAB Center for Disease Preparedness, as well as a professor in the Division of Developmental and Clinical Immunology.
