Abstract

Rett syndrome (RTT) is a neurodevelopmental disorder primarily caused by mutations in the X chromosome-linked gene Methyl-CpG Binding Protein 2 (MECP2). Restoring MeCP2 expression after disease onset in a mouse model of RTT reverses phenotypes, providing hope for development of treatments for RTT. Translatable biomarkers of improvement and treatment responses have the potential to accelerate both preclinical and clinical evaluation of targeted therapies in RTT. Studies in people with and mouse models of RTT have identified neurophysiological features, such as auditory event-related potentials, that correlate with disease severity, suggesting that they could be useful as biomarkers of disease improvement or early treatment response. We recently demonstrated that treatment of RTT mice with a positive allosteric modulator (PAM) of muscarinic acetylcholine subtype 1 receptor (M1) improved phenotypes, suggesting that modulation of M1 activity is a potential therapy in RTT. To evaluate whether neurophysiological features could be useful biomarkers to assess the effects of M1 PAM treatment, we acutely administered the M1 PAM VU0486846 (VU846) at doses of 1, 3, 10 and 30 ​mg/kg in wildtype and RTT mice. This resulted in an inverted U-shaped dose response with maximal improvement of AEP features at 3 ​mg/kg but with no marked effect on basal EEG power or epileptiform discharges in RTT mice and no significant changes in wildtype mice. These findings suggest that M1 potentiation can improve neural circuit synchrony to auditory stimuli in RTT mice and that neurophysiological features have potential as pharmacodynamic or treatment-responsive biomarkers for preclinical and clinical evaluation of putative therapies in RTT.

Abstract

Abstract: Accumulating evidence shows a causative role for the bone marrow (BM) in the genesis and progression of pulmonary hypertension (PH). Engraftment of BM hematopoietic stem cells from PH patients to mice reproduces the cardiopulmonary pathology of PH. However, it is unknown whether healthy BM can prevent the development of right heart disease. Caveolin-1–deficient (CAV-1 KO) mice develop cardiopulmonary disease with manifestations resembling PH, including elevated right ventricular (RV) systolic pressure (RVSP), RV hypertrophy, and pulmonary endothelial proliferative disease. Here, we hypothesize that engraftment of healthy BM to CAV-1 KO mice will prevent pulmonary vascular remodeling and development of the cardiopulmonary disease. CAV-1 KO mice and wild-type (WT) mice underwent transplantation with WT or CAV-1 KO BM. Hematopoietic differentiation was analyzed by flow cytometry. Pulmonary endothelial remodeling was quantified by CD31 image analysis. RVSP and RV cardiomyocyte area or Fulton's index were used to analyze RV hypertrophy. Maladaptive RV hypertrophy was determined by quantification of RV fibrosis. Transplantation of CAV-1 KO BM into healthy recipient WT mice led to elevation of RVSP, RV hypertrophy, and pulmonary endothelial remodeling. Reconstitution of CAV-1 KO with WT BM prevented spontaneous development of PH, including elevation of RVSP and maladaptive RV hypertrophy, but not pulmonary endothelial remodeling. Healthy BM has a protective role in the right ventricle independent of pulmonary vascular disease.
