Schwann cells form basal laminae (BLs) containing laminin-2 (Ln-2; heterotrimer alpha2beta1gamma1) and Ln-8 (alpha4beta1gamma1). Loss of Ln-2 in humans and mice carrying alpha2-chain mutations prevents developing Schwann cells from fully defasciculating axons, resulting in partial amyelination. The principal pathogenic mechanism is thought to derive from(More)
Centella asiatica (CA), commonly named gotu kola, is an Ayurvedic herb used to enhance memory and nerve function. To investigate the potential use of CA in Alzheimer's disease (AD), we examined the effects of a water extract of CA (GKW) in the Tg2576 mouse, a murine model of AD with high β-amyloid burden. Orally administered GKW attenuated(More)
The immunosuppressant drug FK506 (tacrolimus) accelerates nerve regeneration in vivo and increases neurite elongation in vitro. We have proposed that the mechanism involves binding to the FK506-binding protein 52, a chaperone component of mature steroid receptor complexes, and a subsequent 'gain-of-function' involving p23 dissociation from Hsp-90 in the(More)
