Our major research
topic is focused on secreted phospholipases A2 (sPLA2), both
those from animal toxins and those endogenous to humans. We are interested in the molecular mechanisms of action of toxic
sPLA2, particularly those
with presynaptic neurotoxicity, anticoagulant
activity and myotoxicity, as well
as the roles of endogenous sPLA2 in pathological and physiological processes in mammals. We are examining the function of these proteins
in different cell processes, such as neuronal apoptosis and neurodegeneration,
cell proliferation and carcinogenesis, particularly in
breast cancer, activity of mitochondria
and inflammation, e.g. in rheumatoid arthritis.
Our group is also involved in investigating the biological roles of products of
the enzymatic activity of sPLA2, fatty acids, lysophospholipids
and their metabolites, as
well as pathologies connected with lipid metabolism, such as cardiovascular diseases, obesity and ageing. Our approach is to identify and characterize constituents of animal toxins with interesting pharmacological activities, potentially useful in medicine
and as molecular tools to address
research problems in physiology. |
