Membrane trafficking pathways target various molecules to their specific destinations within the cell as well as in and out of the cell, and thus are essential for fundamental aspects of eukaryotic life including nutrient uptake, growth factor regulation, synaptic signal transduction, infection, etc. Importance of these pathways is illustrated by the growing number of diseases and cancers associated with defects in these pathways.

A number of reports have shown that various signalling molecules physically associate with intracellular membranes, thus being ideally placed to control membrane traffic or traffic-mediated signalling. The research in my laboratory aims to understand how membrane trafficking and cell signalling are coupled within the cell.

During my post-doctoral studies I performed a genome-wide RNAi screen in soil nematode C. elegans to find novel regulators of membrane traffic. In this work, many new components involved in vesicular trafficking and/or cell signalling were identified. Since then the powerful genetics in combination with the relatively simple cellular complexity of C. elegans has been proven to be beneficial in studying membrane transport and cell signalling pathways in vivo.

Currently, work in my lab focuses on understanding the cross-talk of membrane trafficking and cell signalling within the cell via deciphering interactions and trafficking of several membrane proteins/receptors:

1)    Fibroblast Growth Factor Receptor (FGFR): understanding how FGFR and its downstream signalling pathways regulate membrane trafficking;

2)    Amyloid Precursor Protein (APP): dissecting physiological role of APP by studying its trafficking, the interactors of its intracellular domain and the biological consequences of these interactions. 

3)    Aquaporin 4 (AQP4): identifying the key membrane transport regulators involved in trafficking AQP4 between the plasma membrane and intracellular vesicles in response to changes in osmolarity.

Recently I have established a collaboration to study the role of Stress Granules in C. elegans Alzheimer's and Parkinson's Disease models. 

Stress granules (SGs) are dense aggregations of protein and mRNA molecules and are highly dynamic structures reflecting cellular stress response. They rapidly form in the presence of acute stress, and rapidly disassemble once the stressor is removed, playing an essential role to cell survival following stress. However, abnormal accumulation of SGs contributes to the pathology of several neurodegenerative diseases. In pathological conditions, the presence of a persistent stress allows time for SGs to mature into more stable complexes, with important consequences for the cellular metabolism.
