Research Achievements My research has focussed largely on the topic of cell adhesion in the immune system. This began in the early 90s with my construction of cDNA libraries and their use in expression cloning strategies to isolate and sequence important leukocyte receptors including CD38, an ADP ribosyl cyclase associated with T cell activation, CD24, a GPI anchored receptor in B cells, CMRF35 an Ig superfamily immunoregulatory receptor and CD44, the primary receptor for hyaluronan involved in inflammatory trafficking. My work on CD44 revealed the intron/exon structure of the CD44 gene and its unusually complex degree of alternative splicing and went on to characterize the function of discrete heparan sulphate modified CD44 splice variants in sequestering growth factors and chemokines. I also applied similar technology to clone cDNAs for surface antigens in the insect stages of Trypanosoma brucei, the parasite responsible for African sleeping sickness, revisiting an earlier interest gained during my PhD and initial postdoctoral research. Following from such research in 1999 I went on to identify LYVE-1, a gene closely related to CD44 that encodes a hyaluronan receptor expressed preferentially in lymphatic endothelium. This discovery provided clinical researchers, pathologists and scientists with a powerful marker to distinguish lymphatic from blood vessels and was instrumental in moving the field of lymphatic vascular biology forwards. For example over the subsequent period my group was involved in key collaborations that led to the current understanding of how the lymphatics derive from the blood vasculature during embryonic development and how mutations in key genes can lead to vascular abnormalities in the adult, how the lymphatics control the trafficking of antigen presenting cells to lymph nodes for the generation of immune responses in inflammation and how tumours exploit/manipulate the lymphatics for metastasis. We also developed methods to isolate and culture primary lymphatic endothelial cells in vitro and study mechanisms for adhesion and transmigration. Closely intercalated within this work has been our continued interest in the specific role of hyaluronan receptors, notably LYVE-1 in lymphatic trafficking, its structure and likely function as a gatekeeper for cell entry to initial lymphatic vessels. This has led to key publications including those describing the basic phenotype of LYVE-1 knockout mice, the crystal and NMR structure of CD44 in complex with hyaluronan and its conformational transition between on and off binding states, and the mechanism for regulating LYVE-1 receptor function through glycosylation. Current and ongoing work involving my lab and our national and international collaborators is revealing the molecular details of how LYVE-1:HA interactions mediate not only leukocyte transmigration but also adherence and dissemination of HA encapsulated pathogens such as Strep pyogenes, the causative agent of tonsillar pharyngitis and necrotizing fasciitis. What are the Future Aims of Your Current Group?) Our goals for the next five years have been formulated for the MRC quinquennial review process and were approved by the review committee and MRC IIB during their site visit in December 2011. These represent a logical progression from previous studies and may be summarised as follows 1. To elucidate the structure of the natively glycosylated CD44 ligand binding domain in order to better understand the allosteric regulation of hyaluronan binding and to generate a crystal structure for the LYVE-1 homodimer. 2. To investigate the molecular basis by which LYVE-1 functions as a gatekeeper for leukocyte entry to lymphatic vessels through interaction with its ligand HA, with a particular focus on how HA presented by leukocytes may trigger receptor clustering and intracellular signalling that would lead to changes in junctional permeability. 3. To study the involvement of LYVE-1 in regulating the trafficking of leukocytes and tumour cells via lymphatics using LYVE-1 and CD44 knockout mice, fluorescent reporter mice and function blocking mAbs in new models of inflammatory disease and cancer, and determine the importance of hyaluronan interactions in such processes 4. To investigate the role of LYVE-1 within the pulmonary vasculature in effecting resolution of lung inflammation 5. To exploit intravital microscopy and new high-resolution imaging techniques including STED to study the detailed choreography of cell trafficking (ie aims 3 and 4) in vivo and the dynamics of LYVE-1 surface distribution in vitro (aim 2). 6. To investigate the role of LYVE-1 as a receptor for lymphatic dissemination of the hyaluronan encapsulated pathogen Strep pyogenes, the causative agent of tonsillar pharyngitis and necrotizing fasciitis. How do the aims of your research fit with the aims of the WIMM and Division of Medicine The research carried out by my group is based on a core of fundamental, curiosity driven scientific research, which has consistently delivered findings applicable to preclinical translation. The work proposed for the coming five years is likely to further strengthen this latter aspect. According to my understanding of the aims, this is precisely what the WIMM was established to do. Lay Summary of Research Our immune system provides constant surveillance against microorganisms that occasionally breach the body surfaces and enter as a result of infection or physical injury. What actually happens is that specialized cells called phagocytes and dendritic cells close to these surfaces engulf the foreign invaders and carry them to the lymph nodes - glands in which white cells termed lymphocytes reside. When lymphocytes meet these invaders, they respond by multiplying their numbers and moving from the lymph nodes via the blood to the tissues where they seek out and destroy any surviving microorganisms. The route by which engulfed invaders reach the lymph nodes to trigger this critical series of events is quite intricate. It consists of a network of small vessels termed lymphatics that are distinct from blood vessels and that carry cells in a clear fluid called lymph. Without this network there would be no route to alert lymph node lymphocytes to the presence of infection and hence we would not survive. Surprisingly, scientists still understand little about the workings of the lymphatic system despite its importance. The research in my laboratory is aimed at understanding how phagocytes and dendritic cells enter and navigate within lymphatic vessels, which molecules assist them in the process, and how cancer cells hijack the system to spread to lymph nodes while avoiding destruction by the host immune response. It is hoped that this will allow us to develop future drugs that manipulate lymphatic trafficking, promoting helpful immune responses to vaccines on the one hand and blocking harmful responses that produce chronic inflammation or autoimmunity on the other.
