Research

My primary interest is in the role of B cell receptor (BCR) in the development of B cell malignancies. The immunoglobulin (Ig) – the largest component of BCR – is a key molecule for B cells. Individually constructed during antigen-driven somatic hypermutation of rearranged immunoglobulin V(D)J genes, this receptor is "designed" to recognise a specific antigen. The analysis of the Ig genes allows us to reveal a clonal history of a malignant B cell tracking down a cell of origin.  

The BCR signalling, a part of the support received by the CLL microenvironment, provides favourable conditions for CLL cells' survival and eventually, disease progression. Therefore, the dissection of the BCR signalling provides us clues to possible targets for successful therapeutic attack and helps developing new approaches to the treatment of the B-cell malignancies.  

Currently, I am leading on a number of research projects looking into the development of B-cell malignancies and the role of the B-cell receptor in B-cell lymphoma and leukaemia.

Biography

I studied biology at the Tomsk State University (MSc Biology, 1996, Tomsk, Russia). I then completed my PhD project at the Institute of Clinical Immunology (PhD, 2001, Novosibirsk, Russia). In 2002 I joined the Tenovus Research Laboratory at the University of Southampton. In 2007 I transferred, within Southampton, and joined the Chronic lymphocytic leukemia project at Cancer Research Clinical Centre. In May 2014 I was appointed Lecturer at Barts Cancer Institute, Queen Mary University of London.
