Laboratory Introduction

Fatty acids are important nutrients for various biological reactions. Recent epidemiological evidence suggests that dietary consumption of some long chain fatty acids such as DHA and EPA, commonly found in fish oil, may modify the risk for certain disorders. However, the molecular basis of their actions is still to be clarified.
Long chain fatty acids (LCFA), are key players in cell functions, including membrane remodeling, control of receptor activity and signal transduction. Therefore it is to be expected that fatty acid binding proteins, due to their ability to binding LCFAs with high affinity, participate in neural, immune and other cell functions as modulators for their homeostatic regulation. The major goal of our laboratory is to clarify the molecular basis of the interactions between the fatty acids and a number of physiological responses by focusing on the biological role of intracellular lipid binding proteins.
