About one-third of patients with major depressive disorder (MDD) are treatment resistant. Ketamine is very effective in treatment-resistant depression, but it is associated with psychotomimetic effects. Metabotropic glutamate mGlu2 and mGlu3 receptors negatively regulate the release of glutamate and are involved in the pathogenesis of depression.
Adolore Biotherapeutics Inc. has announced that the FDA has granted orphan drug designation to the company’s Kv7-activating rdHSV-CA8* gene therapy for treatment of primary and secondary erythromelalgia.
Neuroplastogens are an emerging class of compounds that promote neuroplasticity in the brain without inducing hallucinogenic effects. Transneural Therapeutics Inc. has presented data regarding their new neuroplastogen TN-001 for treating major depressive disorder; TN-001 was assayed in vitro and in vivo.
Post-traumatic stress disorder (PTSD) is a condition with limited effective therapeutic options to date, where 5-HT2A receptor agonists show promise for enhancing cortical plasticity in the brain and aiming in the processing of trauma. Engrail Therapeutics Inc. has presented data for their 5-HT2A agonist and dopamine D2/D3 receptor antagonist neuroplastogen ENX-205 for the potential treatment of PTSD.
For decades, scientists have searched for a mechanistic link between viral infection and multiple sclerosis (MS). Insights from three studies recently published in Cell bring that connection into sharper focus. By tracing how the immune system responds to Epstein-Barr virus (EBV) – and how those responses can misfire against the brain – researchers are beginning to uncover a compelling biological explanation for MS.
Dentatorubral-pallidoluysian atrophy (DRPLA) is a lethal neurodegenerative disorder caused by pathogenic expansion of CAG repeats within the atrophin-1 (ATN1) gene. As DRPLA belongs to the broader class of repeat expansion disorders (RED) that are driven by toxic gain-of-function effects, reduction or elimination of ATN1 expression is predicted to provide therapeutic benefit.
Researchers at Iama Therapeutics Srl and Italian Institute of Technology have disclosed solute carrier family 12 member 2 (SLC12A2; NKCC1) inhibitors reported to be useful for the treatment of Down syndrome.
Neurotrimin (NTM) is a member of the IgLON family, the disruption of which has been tied to emotional learning deficits and anxiety-like behavior in animal models. A mutation in the NTM gene was found to disrupt NTM protein heterodimerization with other IgLON family members, suggesting a potential link between NTM dysfunction and neurodevelopmental and behavioral disorders.
