Annals of Neurology November 2025

Investigated the role of HLA allelic variants in neuropathological burden across 539 Lewy body disease cases using high-resolution whole-genome sequencing. Identified significant associations between specific HLA alleles and Lewy body counts, amyloid pathology, and disease subtype, highlighting immune-related genetic factors in LBD etiology.

Describing the diversity of MAPT transcripts in the parietal cortex of Pick's disease patients

N. Tamvaka*, M.G. Stuber*, M. Gavrielatos, A.I. Soto-Beasley, M.G. Heckman, Y. Ren, E. Udine, Z.S. Quicksall, D. Liskey, M. Castanedes-Casey, Z.K. Wszolek, B.F. Boeve, K.A. Josephs, N. Graff-Radford, M. van Blitterswijk, M.E. Murray, S.F. Roemer, D.W. Dickson, O.A. Ross

Characterized MAPT alternative splicing patterns using long-read RNA sequencing in Pick's disease, a rare 3R tauopathy. Identified novel transcripts and complex splicing regulation extending beyond canonical isoforms, providing new insights into tau transcript diversity in the context of neurodegeneration.

Characterizing the expression profile of 3R tau pathology in Pick's disease

N. Tamvaka, A.I. Soto-Beasley, M. Gavrielatos, M.G. Heckman, Y. Ren, E. Udine, Z.S. Quicksall, D. Liskey, M. Castanedes-Casey, Z.K. Wszolek, B.F. Boeve, K.A. Josephs, N. Graff-Radford, M. van Blitterswijk, M.E. Murray, S.F. Roemer, D.W. Dickson, O.A. Ross

Science Advances 11 (18), eadt6105 · May 2025

Performed the first bulk transcriptomics study on Pick's disease using both short- and long-read sequencing on 28 PiD and 15 control parietal cortex samples. Identified CCL2 as the gene most strongly associated with 3R tau pathology and uncovered co-expressed gene networks involving mRNA processing, mitochondrial function, and immune processes.

A Machine Learning-Based Web Tool for the Severity Prediction of COVID-19

A. Christodoulou, M.S. Katsarou, C. Emmanouil, M. Gavrielatos, D. Georgiou, A. Tsolakou, M. Papasavva, V. Economou, V. Nanou, I. Nikolopoulos, M. Daganou, A. Argyraki, E. Stefanidis, G. Metaxas, E. Panagiotou, I. Michalopoulos, N. Drakoulis

BioTech 13 (3), 22 · July 2024

Developed a machine learning-based web tool to predict COVID-19 severity from demographic and clinical features in 344 unvaccinated patients. Identified age, sex, hypertension, obesity, and cancer as key predictors of ICU admission, and deployed an optimized classification model as a publicly accessible prognostic tool.

Benchmarking of next and third generation sequencing technologies and their associated algorithms for de novo genome assembly

M. Gavrielatos, K. Kyriakidis, D.A. Spandidos, I. Michalopoulos

Molecular Medicine Reports 23 (4), 251 · February 2021

Benchmarked hybrid and long-read genome assembly strategies using Illumina, Nanopore, and PacBio HiFi data on Drosophila and human genomes. Demonstrated that HiFi sequencing enables less computationally demanding assembly with novel algorithms, potentially democratizing genome assembly for smaller labs with limited resources.
