-
Alzheimer disease (AD) pathology begins 15–20 years before clinical symptoms, necessitating non - invasive biomarkers for early diagnosis.
-
This position is justified by the fact that not all individuals with positive biomarkers will progress to symptomatic disease, as well as by the considerable variability in biomarker results depending on the type of marker and the laboratory performing the analysis (3).Both frameworks agree that biomarkers enhance diagnostic certainty but differ in the degree of reliance placed upon them.

Microglia are implicated in the progression of Alzheimer's disease (AD) pathology from its earliest stages, suggesting that cerebrospinal fluid (CSF) microglia profiling across clinical AD stages can aid in treatment development and monitoring.
-
Inflammatory responses are characterized by the activation of immune cells, while inflammatory biomarkers intricately interact with the immune system.

Fourteen participants (21.5%) converted to MCI, and 24 (36.9%) were classified as Prog-1.Plasma biomarkers did not show consistent predictive performance across predefined endpoints (all p>0.05), although NfL demonstrated modest discrimination for MCI conversion (area under the curve [AUC] 0.686, p=0.008).Hippocampal volume demonstrated significant discriminative performance for MCI conversion (AUC 0.765, p=0.016) and Prog-1 (AUC 0.933, p<0.001).For Prog-2, hippocampal volume showed high discrimination (AUC 0.952, p<0.001).WMH grade also demonstrated significant discrimination for MCI conversion (AUC 0.835, p<0.001) and Prog-1 (AUC 0.857, p<0.001).Bootstrap analyses (1,000 iterations) tended to show higher AUC estimates for imaging markers compared with plasma biomarkers.

Η νευρωνική εκφύλιση και δυσλειτουργία αποτελούν χαρακτηριστικά γνωρίσματα των νευροεκφυλιστικών ασθενειών. Σημαντική πρόκληση είναι η ανάπτυξη αξιόπιστων διαγνωστικών εργαλείων που θα επιτρέπουν την έγκαιρη διάγνωση των νόσων αυτών. Πρώτος στόχος της παρούσας διδακτορικής διατριβής είναι ο ποσοτικός προσδιορισμός επιλεγμένων πρωτεϊνικών βιοδεικτών στο εγκεφαλονωτιαίο υγρό (ΕΝΥ) και στο αίμα, με σκοπό την υποστήριξη της διαφορικής διάγνωσης διαφόρων νευροεκφυλιστικών ασθενειών. Εφαρμόστηκαν μονοπλεκτικές δοκιμασίες για τον εντοπισμό του uPAR σε ασθενείς με σποραδική νόσο Creutzfeldt-Jakob, καθώς και των TAU, α-synuclein (α-syn), YKL-40 σε ασθενείς με συνουκλεϊνοπάθειες. Η έλλειψη ευαισθησίας και ειδικότητας των μονοπλεκτικών δοκιμασιών οδήγησε στην αξιοποίηση της πολυπλεκτικής πλατφόρμας SIMOA τεσσάρων βιοδεικτών (GFAP, NfL, TAU, UCH-L1), σε δύο διαφορετικές κλινικές κοόρτες. Στους ασθενείς με νόσο Alzheimer (AD) και μετωποκροταφική άνοια (FTD), ο βιοδείκτης με την καλύτερη διαγνωστική απόδοση ήταν ο UCH-L1 στο ΕΝΥ, με τιμές διαχωρισμού στα >1260 pg/mL για AD και >1052 pg/mL για FTD. Η NfL στο ΕΝΥ έδειξε καλή διαγνωστική ακρίβεια για τη διάκριση ασθενών με AD και FTD από υγιείς μάρτυρες, με τιμή διαχωρισμού >688,8 pg/mL και >463,9 pg/mL, αντίστοιχα. Η TAU στο ΕΝΥ εμφάνισε τη δεύτερη καλύτερη απόδοση μετά το UCH-L1 για τη διάκριση των AD από μάρτυρες, με τιμή διαχωρισμού >137,0 pg/mL, ενώ έδειξε καλή ακρίβεια και στη διάκριση των AD από τους FTD. Επίσης, καλή διαγνωστική ικανότητα παρατηρήθηκε στη διάκριση FTD από μάρτυρες με τιμή διαχωρισμού >111,3 pg/mL. Τέλος, η GFAP στο ΕΝΥ παρουσίασε μετρίου βαθμού ακρίβεια στη διάκριση AD από ομάδα μαρτύρων με τιμή διαχωρισμού >5942 pg/mL. Στη Σκλήρυνση κατά πλάκας (MS) και στο Kλινικά μεμονωμένο σύνδρομο (CIS), η NfL ορού και ΕΝΥ έδειξε μέτρια διαγνωστική ακρίβεια στη διάκριση των MS από τους μάρτυρες, με τιμές διαχωρισμού >5,909 pg/mL και >453,4 pg/mL, αντίστοιχα. Η GFAP ορού παρουσίασε μέτρια διακριτική ικανότητα με τιμή διαχωρισμού >48,08 pg/mL στους MS έναντι των υγιών. Ενώ τέλος η TAU ήταν ο βιοδείκτης με την καλύτερη απόδοση στη διάκριση MS / CIS από τους μάρτυρες, με τιμή διαχωρισμού στον ορό >0,5823 / >0,5950 pg/mL, αντίστοιχα, ενώ στο ΕΝΥ <76,47 / <75,26 pg/mL, αντίστοιχα. Δεύτερος στόχος της μελέτης, είναι η διερεύνηση του ρόλου των νευρωνικών εξωσωμάτων στην παθογένεση και εξάπλωση των νευροεκφυλιστικών ασθενειών (με έμφαση στη νόσο Prion). Για τον σκοπό αυτό αξιοποιήθηκε παθολογικό μοντέλο μυός RML, το οπ
