Putative molecular mediators of autism

p75NTR

Developmentally regulated brain expression or function with an inflection point at ~2 years in the human1

Developmentally regulated brain expression with an inflection point at ~2 years in human7,13

Differential expression in cerebellar Purkinje cells, cholinergic basal forebrain, hippocampal pyramidal cells relative to rest of the brain3,14

Differential expression in cerebellar Purkinje cells, cholinergic basal forebrain, hippocampal pyramidal cells relative to rest of the brain8,13

Modulated by oxidative stress and inflammation5,6

Induces enhanced GSSG → GSH cycling in oxidative conditions9,10

Involved in BDNF activity4

BDNF is one of its cognate ligands7

Expression and/or activity (itself and/or downstream effectors) altered in known models of autism15

All molecular species known and published to be part of the p75NTR ‘interactome’ exhibit altered (and most, upregulated) expression in the prenatal valproate model of autism16
