RESEARCH INTEREST

Microparticles and pathophysiology in thalassemia

        Rationale and Research Methodology: Thalassemia is a commonly genetic disease in Thailand as 20-30% α-thalassemia
and 3-9% β-thalassemia (~13% of population is combined with Hb E). The couples in Thailand are ~5.6% of risk to giving
birth to babies with severe hemoglobinopathies; Hb Bart’s hydrops fetalis, Hb H disease, homozygous β-thalassemia,
and β-thalassemia/Hb E. Although the molecular defects of both α- and β-globin genes have been defined, the
consequences of multiple gene-to-gene interactions in order to the understanding of mechanism/severity in patients
are still unclear. The imbalance of globin chain synthesis in thalassemic erythroid cells leads to denaturation and
degradation of excess unbounded globin with associated with high amounts of reactive oxygen species (ROS) but low
level of antioxidant in erythroid cells. There have been several proposed that the effects of ROS play an important role
on cell division and proliferation, risk to cell death, cytoskeleton membrane disruption, loss of plasma membrane
asymmetry and one of factors to membrane vesiculation (microparticles, MP).
        MPs display the cell surface proteins and biological molecules (miRNA, RNA, DNA and some chemical agents) of multiple
parent cell types including platelets, RBCs, endothelial cells, lymphocytes, monocytes and granulocytes. The physiological
roles of MPs are derived into 3 major topics: coagulation, inflammation and endothelial dysfunction. In thalassemia,
patientshad high levels of circulating membrane-derived MPs with high risk to thromboembolic events. However, mechanism
and biological effects of MP in thalassemia are still unclear. Therefore, both thalassemic patients and mice are a good model
for basic research to understand the pathophysiology in thalassemia and also develop to therapeutics.
