World's First Metal-based Probes for Detection of Dopamine Receptors - Developed by HKBU Researchers
Hong Kong Baptist University Researchers Develop Metal-Based Probes for Dopamine Receptor Identification
A groundbreaking achievement has been made by a team of researchers from Hong Kong Baptist University, who have successfully developed the world's first metal-based probes for identifying dopamine receptors in living cells. This innovation has provided valuable insights into the role of dopamine receptors in carcinogenesis.
Dopamine, an essential neurotransmitter in the central nervous system, belongs to the catecholamine and phenethylamine class of organic chemicals. It plays a crucial role in various neurological processes.
In the field of neurodegenerative diseases like Parkinson's disease, dopamine receptors have been extensively studied. However, traditional detection methods for dopamine receptors were costly and incompatible with living systems.
The introduction of these new metal-based probes now allows for easy identification, monitoring, and real-time tracking of dopamine receptors in lung cancer cells. These probes overcome challenges related to poor photostability and photobleaching commonly encountered in other detection techniques.
Moreover, the study sheds light on the significance of dopamine receptors in cancer pathogenesis and enables early disease detection, ultimately increasing the survival rates of patients with severe cancers like lung cancer.
The research collaboration involved professors from the School of Chinese Medicine at HKBU, City University of Hong Kong, University of Florida (USA), and Hunan University (China). Their combined efforts focused on cell imaging of dopamine receptors using iridium (III).
The study demonstrated a correlation between the imaging color intensity and the expression levels of dopamine receptors on cancer cells within the human body.
These metal-based probes represent a powerful tool not only for examining the role of dopamine receptors in cancer pathogenesis but also for studying the internalization process of dopamine receptors in living cells.
