Research summary

Our laboratory is   involved   in   unraveling   the   fundamental   molecular mechanism of amyloid formation that has been implicated in  a  variety  of deadly  human  disorders.  We have started investigating the formation of amyloid pore by AFM and Raman spectroscopy and have made an important progress  towards  the  nanoscopic  imaging  of  amyloid  fibrils  beyond  the diffraction-limit.  Using near-field scanning optical microscopy  (NSOM),  we were able to resolve the fibrils that were spatially separated by ~ 75 nm. We are also investigating membrane-induced folding and  amyloid  formation  of  α- synuclein,  an  intrinsically  disordered  protein.  It has been  implicated  in  a number of potentially important neuronal functions as well as in the etiology of Parkinson’s disease. Based on our results, we proposed a structural model of α-synuclein in the membrane-bound form. Recently, we have embarked upon studying functional prions and amyloids that are implicated in many important biological functions.
