The Department of Molecular Microbiology teaches introductory courses in microbiology and pathogenic microorganisms for first-year medical students and graduate students. In conjunction with the Division of Biology & Biomedical Sciences (DBBS) program in Molecular Microbiology and Microbial Pathogenesis, the department also offers a number of advanced courses, primarily designed for graduate students, but open to medical students. Advanced elective research activities are offered by faculty in the department.

The Doering lab studies the opportunistic fungal pathogen, Cryptococcus neoformans, with the dual motivations of elucidating basic biology and identifying potential drug targets. Projects include studies of the synthesis and regulation of the main cryptococcal virulence factor, its polysaccharide capsule, and investigation of host fungal interactions. Current approaches include those of biochemistry, cell and molecular biology, and genetics; studies also include high-throughput analysis of host-pathogen interactions and computational approaches to reconstructing the capsule regulatory network.

Pathogenic mechanisms and disease outcomes in the urinary tract. Work in the Hultgren lab blends multiple scientific disciplines to elucidate bacterial and host mechanisms that determine the onset, course and outcome of interactions between a host mucosal surface and bacterial pathogens. Using genetics, genomics, biochemistry, structural biology, high-resolution imaging, animal models, clinical studies and combinatorial chemistry, we have illuminated new ways in which intracellular lifestyles and community behavior play critical roles in the pathogenesis of urinary tract infection. We have uncovered new principles of adhesive pili biogenesis in Gram Negative bacteria by the chaperone/usher pathway; delineating the fine molecular details of a donor strand complementation and exchange mechanism by which the energy of final subunit folding is used to complete assembly and extrusion of pili across the outer membrane. We revealed how UPEC use type 1 pili to invade and establish biofilm-like intracellular bacterial communities within bladder cells as part of a mechanism that subverts host defenses and how quiescent intracellular reservoirs can seed recurrent infections. We have uncovered complex networks that govern mucosal epithelial response to infection, which we have shown determines disease outcome. Further, we have made seminal contributions to our understanding of the pathogenesis and response to other uropathogens, polymicrobial infections and catheter-associated UTIs and to the mechanisms by which bacteria form a directed amyloid fiber, curli, which is important in biofilm formation. Together, this work is changing the way UTIs are evaluated, re-shaping models of bacterial infections in general and spawning new technologies to design novel vaccines and anti-microbial therapeutics to diagnose, treat and/or prevent UTIs and their sequelae.

Polymicrobial Infection and Women's Health. Our lab is using biochemical, cellular and animal models to study infectious processes of the female urogenital tract that involve multiple bacterial species. For example, bacterial vaginosis (BV) is a polymicrobial imbalance of the vaginal flora characterized by reductions in beneficial lactobacilli and an overgrowth of mostly Gram negative bacteria. BV is the most common of all vaginal infections and is associated with increased risks of adverse pregnancy outcomes and greater susceptibility to sexually transmitted infections. We are collaborating with clinical investigators to define molecular and biochemical processes of BV and identify patient groups most at risk for adverse events. Another active area of study in the lab involves polymicrobial urinary tract infection (UTI). We have developed a mouse model of polymicrobial UTI and are currently defining novel processes, bacterial factors and the impact of host that contribute to susceptibility.

Antifungal therapy and vaccine development against a fungal pathogen: Cryptococcus neoformans is a significant fungal pathogen, particularly in immunocompromised patients, that causes pulmonary infections and meningoencephalitis. It has been estimated that over 1,000,000 new cases of Cryptococcus occur, with over 650,000 deaths per year, and the majority of these cases are in Africa. Our lab focuses on understanding the structure and the synthesis of the fungal cell wall. We are working on it as a target for antifungal therapies and for vaccine development.

We study the intracellular survival mechanisms of protozoan parasites, focusing on the model parasite Toxoplasma gondii. Current approaches include high-resolution microscopy, genetic mapping of virulence traits, comparative genomic analyses and development of animal models for studying pathogenesis and resistance.

Discovery and characterization of novel viruses. We use functional genomic technologies to identify novel viruses from a variety of clinical samples from diseases of unexplained etiology. We then use epidemiologic and molecular/cellular strategies to define the relevance of newly identified viruses to human disease. A range of new viruses, including polyomaviruses, astroviruses and picronaviruses are under investigation.

M30 MolMB 523 Immunology

The course consists of lectures, laboratory exercises and clinical correlations. It covers all aspects of the immune response — general properties of the immune system; effector molecules; cells and their function; cellular interactions; and immunological diseases. The Immunology course has a heavy component of biochemistry, genetics and cell biology. Some of the basic concepts from these fields should be reviewed during the course. Two laboratory exercises (not required for non-medical students) are based on the POPS (Patient-Oriented Problem-Solving System in Immunology) which consists of workbooks that focus on a specific clinical problem. Students will also meet in small groups (10-15 students) with clinicians to discuss a variety of clinical cases that relate to the course material. The second edition of Cellular and Molecular Immunology by Abbas, Lichtman and Pober is used for the lecture part of the course and Case Studies in Immunology by Rosen and Geha will be used for the clinically oriented small group discussion. Handouts will be given for selected lectures to either clarify or expand on the information in the textbook. The exam consists of 50 multiple-choice questions on the topics described in the lectures and in the laboratory exercises. Prerequisite: medical student status or graduate student status, some background in biochemistry and genetics helpful. Non-medical students register under cross-listed course L41 Biol 5171 with permission of the course director only (spring only).

Credit 37 units.
