There is an enormous and unmet medical need to find efficient methods of prevention, diagnosis and disease- modifying therapies for neurodegenerative disorders, including Alzheimer’s disease (AD), other tauopathies and Parkinson’s disease (PD). The common molecular denominator of tauopathies are pathological forms of tau protein, and in Parkinson’s disease these are pathological forms of -synuclein. Moreover, -synuclein has a distinct role in pathophysiology of tauopathies, mainly in tau hyperphosphorylation and aggregation, and vice versa. Tau pathology relates to conformational changes during oligomerization and assembly resulting in toxicity. Given their role in the pathogenesis, conformationally altered and assembled tau or -synuclein would be a promising molecular target for disease-modifying therapies. However, the field is still lacking a deeper understanding of associated structural changes in the course of assembly and their inducers on the pathway towards pathological forms of these proteins; therefore, the pharma development is hampered. The main aim of the InterTau project is the detailed structural and biophysical characterization of tau and -synuclein -synuclein protein and their variants in monomeric, oligomeric and fibrillar states relevant for AD, other tauopathies. The InterTAU consortium is composed and academic partners with cutting- edge methodologies suitable for functional and structural characterization of the tau assembly pathway by solution and solid-state nuclear magnetic resonance (NMR), cryo-electron microscopy and cellular assays corroborated by bioinformatics. The mutual transfer of complementary expertise envisaged in the project will facilitate academic outcome and biotechnological development. Specific expertise will be transferred from three institutions in North America and one institution from Argentina. The results of InterTAU will be directly translated into innovation in biotech through the non-academic partner. The platform for sharing knowledge will be a foundation of sustainable cooperation beyond the InterTau project.

There remain urgent and unmet needs for the treatment of neurological diseases. Epilepsy is a serious, chronic brain disease characterized by recurrent seizures. Closed-loop, implanted devices offer ways to reduce seizures in drug-resistant patients but their efficacy is poor and they interrupt seizures only after they begin. PRIME capitalizes on a breakthrough discovery that transfer RNA (tRNA) fragments, a novel class of noncoding RNA, increase in patients in advance of when a seizure occurs. We propose to engineer human cells to respond to tRNA fragment elevations as the trigger for pre-emptive release of glial-derived neurotrophic factor (GDNF), a seizure-suppressing and disease-modifying treatment. Artificial Intelligence (AI) algorithms will be used to integrate OR or AND logic gate functions in the switching process, depending on the quantity and type of tRNA fragments and timing of their release in a given epileptic network and a second, fail-safe calcium-dependent pathway will allow GDNF release in the event of a breakthrough seizure. This enables a precise level of personalization in the design of the bio-computing cells, which will be encapsulated into a membrane device within the microenvironment scaffold, enabling the engineered cells to co-exist with natural brain tissue. Validation of the bio-computing cells will be tested in both in vitro microfluidic organ-on-a-chip as well as in vivo tests for effects on spontaneous seizures in rodents with epilepsy. PRIME’s results will provide a transformational diagnostic-therapeutic treatment for epilepsy and other neurological diseases that feature disrupted neuronal network function.
