Hypotheses

#HypothesisTargetScorePrice
#1 Microglial Purinergic Reprogramming P2RY12 0.606 $0.61
P2Y12 receptor expression levels determine whether microglia promote tufted astrocyte formation (low P2Y12) versus astrocytic plaques (high P2Y12) by controlling ATP-mediated tau propagation signals. ...
#2 Aquaporin-4 Polarization Rescue AQP4 0.589 $0.59
4R-tau strains disrupt AQP4 polarization differently in brainstem vs cortical astrocytes, creating distinct perivascular clearance failures. Restoring AQP4 polarity through α-syntrophin modulation cou...
#3 Sphingolipid Metabolism Reprogramming CERS2 0.551 $0.55
Regional differences in ceramide synthase isoform expression (CERS2 vs CERS6) create distinct membrane environments that favor specific 4R-tau conformational states. Pharmacological CERS modulation co...
#4 Complement C1q Subtype Switching C1QA 0.513 $0.51
Brainstem astrocytes express C1qA-dominant complexes promoting tufted morphology, while cortical astrocytes express C1qC-dominant complexes favoring plaque formation. C1q subunit-selective inhibitors ...
#5 Glial Glycocalyx Remodeling Therapy HSPG2 0.505 $0.51
PSP and CBD tau strains differentially interact with region-specific glial glycocalyx compositions, determining astrocytic morphology. Enzymatic remodeling of heparan sulfate proteoglycans could redir...
#6 Ephrin-B2/EphB4 Axis Manipulation EPHB4 0.485 $0.48
Astrocytic ephrin-B2 expression creates regional 'tau reception zones' that determine whether incoming 4R-tau forms tufts or plaques. EphB4 activation therapy could reprogram astrocytes to resist path...
#7 Netrin-1 Gradient Restoration NTN1 0.353 $0.35
Loss of developmental netrin-1 gradients in adult brain allows inappropriate 4R-tau strain migration between regions. Therapeutic netrin-1 delivery could re-establish compartmentalization barriers, pr...
