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)
Axonal regeneration is important for functional recovery following nerve damage. Centella asiatica Urban herb, also known as Hydrocotyle asiatica L., has been used in Ayurvedic medicine for centuries as a nerve tonic. Here, we show that Centella asiatica ethanolic extract (100 microg mL-1) elicits a marked increase in neurite outgrowth in human SH-SY5Y(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)
OBJECTIVE To optimize the different components proportions of the Realgar floating tablets for gastric retention by uniform design and correlation analysis. METHOD With the different dosage of hydroxypropyl methyl cellulose (HPMC) as the tablets frame matrix, uniform design and correlation analysis were used to optimize the best component proportions of(More)
