Natalia Filippova, Ph.D. Natalia Filippova holds an Instructor position at the Department of Neurology, School of Medicine, the University of Alabama at Birmingham, Birmingham, USA. Dr. Filippova received training in cellular biology and electrophysiology in the National Institute of Medical Research, INSERM U29, Paris, France and Bakulev Scientific Center for Cardiovascular Surgery, Moscow, Russia. Dr. Filippova has Ph.D. in Biological Science from Moscow Institute of Developmental Biology, Moscow, Russia and a master’s degree in Physics/Biophysics from Moscow State University, Moscow, Russia. Dr. Filippova acquired extensive post-doctoral training in molecular biology and neurophysiology in the Institute Pasteur, Paris, France and University of Alabama at Birmingham, USA.
Dr. Filippova’ s professional interests include but are not limited to brain cancer research, developmental biology, biophysics of ion channels. Dr. Filippova has an active collaboration with the Southern Research Institute, Birmingham, USA and is deeply involved in the development of a drug discovery axis for glioma treatment based on posttranslational modifications of oncogenic mRNA binding protein HuR and immune checkpoint molecules.
Dr. Filippova is an active member of the Neuroscience community and provides help and consultations to the students, fellows, faculty members and has supervised many research projects.

Research Interest

Dr. Filippova has a broad background in neuroscience with specific training and expertise in i) neurophysiology and structural biology of ion channels in normal and pathological conditions, ii) characterization of signaling pathways involved in centrosome abnormalities and genomic instabilities in early stages of glioma development; iii) in the establishment of drug discovery access of post-translational modifications of mRNA binding protein HuR, whose up-regulation and multimerization are essential for brain tumor progression and immune escape, iv) characterization of immunogenic molecules and cytokines in tumor, tumor niche and lymphatic system. The specifics aims of my past and current research:
• membrane topology and kinase-dependent regulation of NMDA, AMPA/kainate and GABA (GABA-a and GABA-c) receptors;
• characterization of mRNA binding protein HuR as one of the oncogenic regulators of centrosomes function in cancer cells in both, post-transcriptional and post-translational levels;
• chemotherapeutic implications of the inhibition of HuR multimerization in glioma treatment;
• determination of signaling pathway involved in the PDL1 up-regulation in brain tumors and glymphatic's system,
• evaluation of signaling pathways in IDH1-R132mut glioma models leading to the genomic instabilities and immune response failure.
