2011 APMEN sponsored award to participate in “APMEN Viviax Woking Group 1st Annual Meeting ”, Kotakinabalu, Malaysia, 07-10 May, 2011 2014 APMEN/WHO sponsored award to participate in “APMEN Viviax Woking Group 5 th

nual Meeting and Clinical workshop”, Siem Reap, Cambodia, 24-28 November, 2014 RESEARCH INTERESTS 1.Immuno- & Molecular Epidemiology of Plasmodium vivax asexual stage vaccine candidates in Sri Lanka (in relation to potential vaccine candidates PvMSP1, AMA-1 and DBP). Lack of reliable in vivo and in vitro correlates of protective immunity against blood stages of Plasmodium is a great impediment in malaria vaccine development. The study of antibody responses accountable for naturally acquired protection against these antigens in endemic populations (Anuradhapura and Kataragama) in Sri Lanka with regard to total antibody levels, specificities, isotype composition and levels were assayed by in house developed ELISAs. Correlations examined between the degree of in vivo protection of endemic populations with the characteristics of the antibody responses in order to develop in vivo correlates of asexual protective immunity were carried out for MSP-1 and AMA-1 and DBP. The genetic diversity of the malaria parasite poses a vital obstacle for the development of successful vaccines against malaria. The genetic diversity of AMA-1, MSP-1 and DBP of P. vivax in clinical isolates obtained from endemic regions of Sri Lanka were elucidated. The overall aim of this project was to establish the strain specific immunity to these three vaccine candidate antigens in Sri Lanka. This programme has resulted in producing three PhD degrees in collaboaration with the Institut Pasteur, Paris, the Harvard Medical School and the ICGEB in New Delhi. Recently, a project funded by the APMEN was completed in the backdrop of malaria elimination in Sri Lanka, on the comparison of the genetic structure of P. vivax population currently circulating in the country and of that in the early 2000, with respect to both coding and non coding (microsatellites) loci. This was a collaboration with the National Anti-Malaria Campaign, Genetech (Colombo) and the University of Arizona, USA. Funding was awarded in 2016 by the National Researc Council for a new project on “A sero-epidemiological study to provide supportive evidence to establish malaria elimination in Sri Lanka”. 2. Ecto- and endo-parasites of vertebrates of Sri Lanka: Separate projects were completed on parasites of bats, poultry, elephants, toads & frogs, and of ornamental fishes. Two studies were completed on parasites of zoo animals (reptiles & mammals). Parasites of a threatened, endemic rodent as well as of wildlife (elephants) in a sanctuary were successfully completed. 3. Immunology of Rheumatoid & Osteo Arthritis in Sri Lanka: Gaining insights to the immunological mechanisms underlying the aetiopathogenesis of rheumatoid arthritis (RA) and Osteo arthritis (OA) provide new approaches of disease prevention and management. A preliminary study was completed on immunological, socioeconomic and disease characterization aspects of a population of RA patients in Sri Lanka. This pioneering study, conducted in collaboration with the Department of Rheumatology and Rehabilitation, National Hospital, Sri Lanka provides baseline information that may contribute to the aetiopathogenesis of RA in Sri Lanka. Following the completion of a pilot study on immunogenetics of RA in Sri Lanka, an in-depth study is being planned. A study on Osteoimmunology will be conducted in 2017.

4. Screening of natural products for anti malarial, anti rheumatoid arthritic and immune-modulatory activity:With a view to search for novel drugs, herbal decoctions based on native traditional medicine with claims of anti-malarial and anti-RA activity are being screened using both in vitro (parasite cultures) and in vivo (rodent models) studies. Raw papaya leaf extract is being tested to treat thrombocytopenia in a rat model with studies on immunomodulatory and cancer chemopreventive properties as well as toxicity studies of this preparation focused on developing drug leads. A pilot study was completed on screening selected marine sponge extracts for immunomodulatory and cancer chemopreventive activity. These studies are conducted in collaboration with the Sri Lanka Institue of Nanotechnology (SLINTEC). The sponge study is a collaboration with the University of Genova, Italy. 5. Reproductive & Pregnancy Immunology: A pilot study to establish markers of male infertility with respect to the cytokine, Migratory Inhibitory Factor (MIF), and to oxidative stress (ROS) in semen was completed in 2009. Plans are underway to undertake an indepth study in collaboration with the Department of Obstetrics and Gynaecology, Faculty of Medicine, University of Colombo. The association of cytokines with preganancy outcome was investigated through a pilot study with novel findings on in vitro fertilization- embryo transfer (IVF-ET). 6. Development of Immunologic and Molecular Diagnostics:Immunologic (ELISA based on in house produced specific monoclonals) and molecular (LAMP assay) diagnostics are being developed for the Weligama coconut wilt disease causing phytoplasma. This project is of national significance and is a collaborative effort with the Coconut Research Institute and the University of Birmingham, UK. It is planned to continue this project 7.Eco-Immunotoxicology & Nanotoxicology: Following two prototype studies, a more in-depth study on “Study of toxic effects of heavy metals, Cadmium and Chromium, as xenobiotics on Euphlyctis hexadactylus (Indian green frog) in a polluted urban wetland in Sri Lanka” was recently completed. Toxicity of synthesized nanoparticles are also being tested in collaboration with the Department of Chemistry of the University of Colombo. 8. Association of Human Papilloma Virus (HPV) and Oral & Oropharyngeal Cancer (OPC) in Sri Lanka: A pilot study established the immunoepidemiologic association of HPV infections as an aetiologic factor for the development of OPC in Sri Lanka, a research problem which is of global significance. Currently a PhD project on immunologic and molecular epidemiologic evidence on the association of HPV and OPC OPC is ongoing in collaboration with the National Cancer Institute, the Kotalawala Defense University and the Translational Research Institute, Australia. Pilot studies on “HPV associated lung cancer in Sri Lanka” and on “Epigenetic markers using saliva of Oral and pharyngeal cancer patients in Sri Lanka” were recently completed. 9. Deriving in house stem cell lines to assess proliferative, differentiation and toxicity of plant/ sponge extracts: A pilot study was initiated to establish mesenchymal and haemapoetic stem cell lines from umbilical cord and cord blood, respectively. Using these defined cell lines, the proliferative, differentiation and toxicity studies will be conducted to test papaya leaf extract and a Sri Lankan marine sponge extract in order to establish alternative therapies for relevant diseases. This is in collaboration with the University of New South Whales, Australia. Melanocyte stem cells were derived from hair follicles and use of traditional herbal extracts on these to stimulate proliferation and melanogenesis is currently underway. This is a collaboration with the Lady Ridgeway Hospital and the Wickramarachchi Ayurveda Institute, Gampaha.

10. Immunology of noncommunicable diseases: Pilot projects on the immunology of types I and II diabetes mellitus, and Parkinson disease were completed. Two more projects will be initiated on the immunology of colorectal cancer and on osteoimmunology this year. All these projects are collaborations with the Faculty of Medicine of the University of Colombo with additional international collaborations. RESEARCH EXPERIENCE Post-doctoral studies at the University of New Brunswick, Canada included purification, characterization, immunochemical analysis and establishment of the physiology of a novel key enzyme (coniferyl alcohol oxidase) of lignification in conifers. I was responsible for establishing the first monoclonal production facility in the Maritimes, Canada. Doctoral studies carried out at the Malaria Research Unit, University of Colombo was on the immunochemical analysis of asexual erythrocytic stage antigens of Plasmodium vivax using monoclonal antibodies, for the purpose of selecting vaccine candidates against asexual stages of this human parasite. This work lead to the identification of the P. vivax merozoite surface protein 1 (PvMSP1) that is now being pursued as a major vivax vaccine candidate. Also, the antigenic polymorphism of P. vivax asexual blood stages was established for the first time with the inhouse derived panel of 30 monoclonal antibodies. Post-graduate research based on purification and radiolabelling of alpha-feto protein (AFP) from amniotic fluid and raising anti-AFP antibodies in rabbits for the development of a radioimmuno assay (RIA) kit for the diagnosis of hepatocellular carcinoma, was submitted as a dissertation for the MSc programme.
