BTBR/R models of ASD showed differences in the expression of a variety of genes that are indicative of endogenous retrovirus activation. BTBR/R mice exhibit autistic-like behaviors without reduced learning abilities.Read More

Either the upregulation of neurotransmitter receptor genes or suppression of the downregulation could improve synaptic dysfunction associated with age-related neurodegeneration. The findings could assist in the creation of new therapies for Alzheimer's disease that target synaptic plasticity.Read More
