Hypotheses

#HypothesisTargetScorePrice
#1 Purinergic Signaling Polarization Control P2RY1 and P2RX7 0.655 $0.66
The P2Y1/P2X7 receptor ratio determines astrocyte phenotype fate - high P2Y1:P2X7 promotes A2 while high P2X7:P2Y1 drives A1. Selective P2Y1 activation combined with P2X7 antagonism can therapeuticall...
#2 Mechanosensitive Ion Channel Reprogramming PIEZO1 and KCNK2 0.599 $0.60
Disease-associated tissue stiffening activates mechanosensitive PIEZO1 channels in astrocytes, locking them into A1 phenotypes through calcium-dependent inflammatory signaling. Selective PIEZO1 inhibi...
#3 Epigenetic Memory Erasure via TET2 Activation TET2 0.581 $0.58
A1 astrocytes maintain neurotoxic programming through DNA hypermethylation at A2-associated gene loci. Activating TET2 demethylase activity can erase this epigenetic memory, allowing reprogramming to ...
#4 Lipid Droplet Dynamics as Phenotype Switches DGAT1 and SOAT1 0.529 $0.53
A1 and A2 astrocytes differ in lipid droplet composition and dynamics. A2 astrocytes accumulate cholesteryl esters in lipid droplets that serve as anti-inflammatory reservoirs, while A1 astrocytes hav...
#5 Circadian Rhythm Entrainment of Reactive Astrocytes BMAL1 0.519 $0.52
Reactive astrocyte subtypes follow circadian oscillations controlled by BMAL1, with A1 phenotypes peaking during rest phases and A2 during active phases. Chronotherapeutic targeting of astrocytic BMAL...
#6 Mitochondrial Transfer Pathway Enhancement MIRO1 0.513 $0.51
A2 astrocytes can donate healthy mitochondria to neighboring A1 astrocytes via tunneling nanotubes and extracellular vesicles, converting them to neuroprotective phenotypes. Enhancing MIRO1-mediated m...
#7 Metabolic Switch Targeting for A1→A2 Repolarization HK2 0.506 $0.51
Astrocyte phenotype switching can be controlled by manipulating the hexokinase 2 (HK2)/mitochondrial metabolism axis. Enhancing HK2 activity promotes glycolytic flux that drives A2 neuroprotective pro...
