Perinatal Tetrahydrocannabinol Compromises Maternal Care and Increases Litter Attrition in the Long-Evans Rat.

The marijuana legalization trend in the U.S. will likely lead to increased use by younger adults during gestation and postpartum.

Transferrin Receptor Is Necessary for Proper Oligodendrocyte Iron Homeostasis and Development.

To test the hypothesis that the transferrin (Tf) cycle has unique importance for oligodendrocyte development and function, we disrupted the expression of the Tf receptor (Tfr) gene in oligodendrocyte progenitor cells (OPCs) on mice of either sex using the system. This ablation results in the elimination of iron incorporation via the Tf cycle but leaves other Tf functions intact. Mice lacking Tfr, specifically in NG2 or Sox10-positive OPCs, developed a hypomyelination phenotype.

Lanthionine Ketimine Ethyl Ester Accelerates Remyelination in a Mouse Model of Multiple Sclerosis.

Although over 20 disease modifying therapies are approved to treat Multiple Sclerosis (MS), these do not increase remyelination of demyelinated axons or mitigate axon damage. Previous studies showed that lanthionine ketenamine ethyl ester (LKE) reduces clinical signs in the experimental autoimmune encephalomyelitis (EAE) mouse model of MS and increased maturation of oligodendrocyte (OL) progenitor cells (OPCs) . In the current study, we used the cuprizone (CPZ) demyelination model of MS to test if LKE could increase remyelination.
