Research Overview 1

Development of Peptide Vaccination regimens for improve T-cell responses

Peptide vaccines are key immunotherapeutic that could lead to safer and more targeted stimulation of the immune system. However, due to its size, immunogenecity is likely to be poorer compared to subunit vaccine or full protein vaccine. A key area that is required to enable efficient stimulation of the immune system when peptides are use as targets is adjuvants. Adjuvant is derived from the Latin word adiuvare, that means to help. Here, adjuvant is defined as an addition that would accelerate, prolong, or enhance antigen-specific immune responses when used in combination with specific antigens.

Research Overview 1

Anti-cancer therapeutic potential of natural products

The recent discovery of microRNAs has added an exciting new layer of research interest in the fields of medical research in general including cancer. His work mainly on MicroRNA–mediated regulation of apoptosis in cancer cells by various natural products. Besides that, he also studies the molecular mechanism of cell cytotoxicity of natural products. These fundamental findings may provide clues to further our understanding of the mechanisms and roles of microRNAs as key regulators of apoptotic programmed cell death induced by natural products in cancer cells and their prospect in the future medical application, especially in the development of green natural products based anticancer medicine.

Research Overview 2

Pharmacological activities of standardized plants secondary metabolites

His research also concentrate on evaluation of plants secondary metabolites in biological and pharmacological activities (Plant extraction, standardization of plant extract, antitoxoplasma activity, antimicrobial activity, antioxidant activity, hepatoprotective activity, prevention of biofilm formation by C. albicans, wound healing activity, anticancer activity, antidiarrheal activity and toxicology studies) and understanding the mechanism of action of the standardized extract or bioactive compound on various pathogenic microbes such as Candida albicans, Helicobacter pylori, Pseudomonas aeruginosa and Aspergillus fumigatus.

Research Overview 3

Animal Research

His research also concentrates on using the animal model to prove the efficacy natural product which showed good activity at in vitro level. He uses the animal model in acute and chronic oral toxicity study, wound healing activity, infected wound healing activity, hepatoprotective study and in vivo antimicrobial study.

Research Interests

Biomarker discovery for parasitic diseases, recombinant proteins; protein expression and purification, immunoassay development and evaluation, lateral flow rapid test

Research Overview 1

Rapid diagnostic tests lymhatic filariasis

There are two types of lymhatic filariasis(LF) namely brugian and bancroftian LF, the latter comprised 90% of the global disease burden.  The patented BmR1 recombinant protein was discovered via a targeted immunoscreening of a Brugia malayi cDNA library.  It was then used for development of a lateral flow cassette test called Brugia Rapid for detection of B. malayi and B. timori and has been licensed to Reszon Diagnostics International Sdn. Bhd.  The test had undergone extensive multicenter evaluations/validations in the laboratory and in the field, as well as under operational conditions.  Brugia Rapid has been recognized by the World Health Organization (WHO) for use as a diagnostic tool in brugian LF countries as part of the Global Programme for Elimination of Lymphatic Countries (GPELF). PanLF Rapid, also commercialized by Reszon, is an extension of Brugia Rapid, and contains an additional infection marker called BmSXP that is sensitive for detection of bancroftian filariasis caused by Wuchereria bancrofti. It is meant for use in brugian LF countries that has some areas of possible co-infection with bancroftian filariasis. The Ministry of Health Malaysia is using PanLF in its LF elimination program. BLF Rapid is a prototype rapid test kit for highly sensitive detection of bancroftian filariasis. It has been evaluated in USA (at CDC Atlanta and University of Washington, St Louis),  India and Malaysia with excellent results.

Research Overview 2

Rapid disgnostic tests for amoebiasis

Amoebiasis is caused by the protozoan parasite, Entamoeba histolytica that causes intestinal and extraintestinal amoebiasis. Due to the lack of a rapid test for the latter, we embarked on the analysis of excretory-secretory antigens (ESA) of E. histolytica which led to the discovery of pyruvate phosphate dikinase (PPDK) as a good diagnostic marker for amoebic liver abscess, and a patent has been granted for this finding. The recombinant form of PPDK was produced and a lateral flow rapid IgG4 test was developed which is called XEh Rapid.  The prototype test has undergone multicenter national and international evaluations with positive outcomes.  In addition, we have developed a proof of concept rapid antigen detection test for intestinal amoebiasis using antibodies to rPPDK and ESA. Although the test showed better sensitivity compared to the major antigen detection ELISA in the market, further work will be undertaken to increase the sensitivity of our test, and it will be followed by multicenter evaluations.

Research Overview 3

Rapid diagnostic test for other parasitic diseases

We are also working on developing and refining several other lateral flow rapid tests for parasitic infections.  Tc Rapid is a prototype rapid test for detection of toxocariasis, and it uses several Toxocara canis recombinant proteins, one of them has been patented. Since T. cati has been implicated in some cases of toxocariasis, especially in certain human populations where cats are more favoured than dogs, we are now working on improving Tc Rapid by incorporating a T.cati recombinant protein.

Another recombinant antigen-based lateral flow rapid test, Strongy Rapid, has been developed to detect strongyloidiasis and is now at an advanced stage of development.  Due to the phenomenon of autoinfection, this parasite can survive for many years in the body. Thus immunosuppressed patients who are living or used to live in endemic areas should be tested for this infection to prevent potentially fatal outcomes due to exacerbation of the infection. 

We have also developed a lateral flow rapid test (Hyd Rapid) using a unique recombinant AgB protein for specific IgG4 detection of hydatid disease. An antigen detection test for hydatid disease is also being developed using antibodies to various forms of Echinococcus granulosus antigens. In addition, an early prototype rapid test for IgM detection of toxoplasmosis has been developed using two recombinant proteins, one of them has been filed for patent.
