Treatment Of Obsessive-Compulsive Disorder Via Mental Health Technology, Erika S Trent, Nisha Jagannathan, Eric A Storch

Faculty, Staff and Students Publications

Obsessive-compulsive disorder (OCD) is a debilitating neuropsychiatric disorder that remains chronic unless intervened with evidence-based intervention. Cognitive behavioral therapy (CBT) with exposure and response prevention is the gold-standard psychological intervention for OCD, but many individuals do not receive this intervention due to barriers to accessing treatment. Mental health technology tools such as telehealth, computerized programs, internet-delivered CBT, and mobile applications have been adopted to expand the accessibility of CBT. An up-to-date summary of the evidence base of technology-mediated formats of CBT for OCD treatment is provided. Clinical benefits offered by such approaches, current limitations, and future research directions are discussed.

Over the past 15 years, genetic studies of psychiatric disorders have provided important insight into the contribution of both common variants of small effect, as well as rare exonic and copy number variants with large effect sizes. Genome-wide association studies (GWAS) allow us to understand the intricate polygenicity characteristic of many psychiatric disorders. However, a considerable proportion of single nucleotide polymorphisms (SNPs) implicated in these disorders localize to the non-coding regions of the genome. Unraveling the molecular mechanisms that underlie the etiology of psychiatric illnesses requires integration using functional genomics approaches. Functional genomics methods are critical for developing a mechanistic …

Gene expression changes likely mediate the impact of Alzheimer's disease (AD) neuropathology on cognition, but there are challenges to resolve the proximal causal pathways from postmortem brain transcriptome profiles which lack temporal resolution and are further confounded by mixed pathologies. Here, we functionally dissect 30 AD-associated human brain gene co-expression modules using fruit fly (Drosophila melanogaster) models. Integrating longitudinal RNA-sequencing and behavioral phenotyping, we interrogated the consequences of amyloid beta (Aβ) plaques, tau neurofibrillary tangles, and aging, highlighting hundreds of conserved, differentially expressed genes. To pinpoint causal modules and drivers, we manipulated 344 prioritized targets in vivo, identifying 141 modifiers …

BACKGROUND:

Identifying genetic variants conferring resilience to Alzheimer’s disease and related dementia (ADRD) may hold promise for developing therapeutics.

OBJECTIVE:

To determine genetic associations with being dementia-free at age 85 (DF85).

METHODS:

We examined genetic associations, using whole genome sequencing data, with DF85 in three Trans-Omics for Precision Medicine cohorts and the Alzheimer’s Disease Sequencing Project Phenotype Harmonization Consortium. We tested common variants individually and aggregation of rare (MAF≤1%) coding and non-coding variants in DF85 participants (n=3,657) against individuals who were not DF85 (n=20,010). We verified associations using a stricter control set who developed dementia before age 85 (n=5,552).

RESULTS: …

Structural Determinants Of Ligand Response Specificity In The Mast Cell Activating Gpcr, Mrgprx2, Abiodun Adefola R Adeosun, Melina A Agosto, Olivier Lichtarge, Theodore G Wensel

Faculty, Staff and Students Publications

The mast cell-specific G-protein-coupled receptor (GPCR) MRGPRX2 (Mas-Related G Protein-coupled Receptor X2) has roles in itch and pain, and it mediates clinically relevant allergy-like responses to a diverse assortment of drugs. The varied responses of individuals to MRGPRX2 agonists, leading to drug hypersensitivity reactions in some cases, suggests the presence of consequential variants in the population. However, genetic associations with drug responses are poorly understood. We used heterologously-expressed MRGPRX2 to investigate the effect of 18 naturally occurring non-synonymous single nucleotide polymorphisms on activation by representative compounds from several classes, including neuropeptides, opioid agonists, antibiotics, neuromuscular blocking agents, and polycationic aromatic …

The Hippo pathway effector YAP promotes spontaneous proliferation of Müller glia (MG), suggesting that bypassing Hippo signaling and activating YAP could enhance retinal regeneration. However, whether proliferative adult MGs retain meaningful neurogenic competence remains unclear. Here, using viral delivery of a Hippo-resistant YAP variant to wild-type adult MGs, we achieved transient YAP activation in adult MGs, inducing proliferation followed by cell-cycle withdrawal and differentiation. Intersectional genetic lineage tracing and EdU labeling, combined with transcriptomic analyses, revealed that YAP-activated MGs predominantly regenerate MGs, whereas only a subset gives rise to bipolar cell-like neurons. These results indicate that proliferative MGs acquire a …

Consciousness is a fundamental component of cognition1, but the degree to which higher-order pattern recognition relies on it remains disputed2,3. Here we demonstrate the persistence of oddball discrimination, semantic processing and online prediction in individuals under general-anaesthesia-induced loss of consciousness4,5. Using high-density Neuropixels microelectrodes6 to record both single-unit and local-field-potential neural activity in the human hippocampus while playing a series of tones to anaesthetized patients, we found that hippocampal neurons and local oscillations retained some detection of oddball tones. This effect size grew over the course of the experiment …

Chronic lung allograft dysfunction (CLAD) limits long-term lung graft survival, yet its specific gene expression profiles remain unclear. We performed comprehensive spatial transcriptomic analyses of human lungs from CLAD patients, non-CLAD transplant recipients, and non-transplanted controls. In CLAD, AP-1 target genes, including JUNB and FOS, were significantly upregulated in both the epithelium and endothelium, whereas anti-fibrotic genes such as A2M and surfactant proteins (SFTPA1,2) were upregulated in non-CLAD. The lymphocyte population in CLAD was predominantly composed of T cells, with elevated JAK3-IL7R signaling. TNF and IL-17 signaling pathways were commonly activated in both the epithelium and endothelium, with JUNB and …

Steroid Receptor Coactivators In Immunity – From Function To Emerging Translational Opportunities, Yosef Gilad, David M Lonard

Faculty, Staff and Students Publications

Steroid Receptor Coactivators (SRCs) comprise a family of three paralogous proteins. As transcriptional coactivators SRCs are essential for enabling the full transcriptional output of nuclear receptors (NRs). They regulate the transcriptional activity of nearly all NRs as well as a wide range of non-NR transcription factors. The central role of SRCs in gene regulation is reflected in their broad impact on major physiological and pathological processes, such as development, reproduction, metabolism, immunity and cancer. Although the major impact of SRCs on human health and disease established them as attractive therapeutic targets, their effective pharmacological targeting remained a challenge for nearly …

Generation And Characterization Of Twist1 Acetyl-Mimic And Acetyl-Deficient Mouse Models, Mary Elmeniawi, Xiaobin Yu, Samuel Wen, Gunjan A Bhatia, Lan Liao, Jianming Xu, Walid D Fakhouri

Faculty, Staff and Students Publications

TWIST1 encodes a highly conserved basic helix–loop–helix transcription factor essential for embryonic development from Drosophila to humans. TWIST1 activity is regulated by post‐translational modifications, including phosphorylation during development and cancer metastasis. Recent cancer studies identified acetylation of lysines K73 and K76 as a novel regulatory modification that shifts TWIST1 from a repressive to an activating state during epithelial‐to‐mesenchymal transition (EMT). However, the developmental and in vivo functions of TWIST1 acetylation remain unknown. To investigate the physiological role, we generated the first acetyl‐deficient Twist1 K73,76R K73,76R and acetyl‐mimic Twist1 K73,76Q K73,76Q mouse models using CRISPR/Cas9‐mediated genome editing. Targeted sequencing confirmed substitutions, …

Neural oscillations play a critical role in shaping neuronal firing patterns. While phase-locked neuronal firing ("phase tuning") has been extensively studied in animal models and human invasive recordings, much less is known about whether neurons show preferential firing at specific oscillatory frequencies, termed frequency tuning. Here, we employ human intracranial recordings across several brain regions including hippocampus, entorhinal cortex, anterior and posterior cingulate cortex, and orbitofrontal cortex to test the hypothesis that neurons exhibit frequency-specific firing. We analyzed 357 single units recorded simultaneously with local field potentials in 19 neurosurgical patients during awake resting. We estimated the instantaneous frequency of …

Anterior Cutaneous Nerve Entrapment Syndrome From Glucagon-Like Peptide-1 Receptor Agonist Injection, Neha Singh, Elisa Chaparro, Jordan Michael Shapiro, Emanuel Narcis Husu

Faculty, Staff and Students Publications

Anterior cutaneous nerve entrapment syndrome (ACNES) is an underdiagnosed cause of abdominal pain. We report the first documented ACNES case following subcutaneous administration of glucagon-like peptide-1 receptor agonist. A 44-year-old man developed focal, neuropathic abdominal pain coinciding with initiation of tirzepatide injections. Clinical examination confirmed ACNES diagnosis, and pain improved after relocating injections away from the abdomen and initiating multimodal pharmacotherapy. This case emphasizes the need to consider ACNES in patients endorsing focal abdominal pain with concurrent use of glucagon-like peptide-1 therapy and highlights injection site modification as a simple, effective management strategy while exercising self-restraint with respect to workup.
