Ameliorated cellular hallmarks of myotonic dystrophy in hybrid myotubes from patient and unaffected donor cells.

Background: Cell-based strategies are being explored as a therapeutic option for muscular dystrophies, using a variety of cell types from different origin and with different characteristics. Primary pericytes are multifunctional cells found in the capillary bed that exhibit stem cell-like and myogenic regenerative properties. This unique combination allows them to be applied systemically, presenting a promising opportunity for body-wide muscle regeneration.

Intrinsic Myogenic Potential of Skeletal Muscle-Derived Pericytes from Patients with Myotonic Dystrophy Type 1.

Pericytes are multipotent, vessel-associated progenitors that exhibit high proliferative capacity, can cross the blood-muscle barrier, and have the ability to home to muscle tissue and contribute to myogenesis. Consequently, pericyte-based therapies hold great promise for muscular dystrophies. A complex multi-system disorder exhibiting muscular dystrophy for which pericytes might be a valuable cell source is myotonic dystrophy type 1 (DM1).

CRISPR/Cas Applications in Myotonic Dystrophy: Expanding Opportunities.

CRISPR/Cas technology holds promise for the development of therapies to treat inherited diseases. Myotonic dystrophy type 1 (DM1) is a severe neuromuscular disorder with a variable multisystemic character for which no cure is yet available. Here, we review CRISPR/Cas-mediated approaches that target the unstable (CTG•CAG)n repeat in the / gene pair, the autosomal dominant mutation that causes DM1.

The anti-absence effect of mGlu5 receptor amplification with VU0360172 is maintained during and after antiepileptogenesis.

Purpose: Ethosuximide (ETX) is the drug of choice for the treatment of patients with absence seizures - taking into account both its efficacy, tolerability and antiepileptogenic properties. However, 47% of subjects failed in ETX-therapy, and most antiepileptic drugs have cognitive side effects. VU0360172, a positive allosteric modulator (PAM) of mGluR5, has been proposed as a new anti-absence drug.
