Microglia critically shape neuronal circuit development and function, yet their region-specific properties and roles in distinct circuits of the human brain remain poorly understood. In this study, we generated region-specific brain organoids (cortical, striatal, and midbrain), each integrated with human microglia, to fill this critical gap. Single-cell RNA sequencing uncovered six distinct microglial subtypes exhibiting unique regional signatures, including a subtype highly enriched for the GABAB receptor gene within striatal organoids. To investigate the contributions of microglia to neural circuitry, we created microglia-incorporated midbrain-striatal assembloids, modeling a core circuit node for many neuropsychiatric disorders, including autism. Using chemogenetics to activate …

The Neuroprotective Effects Of Alpha-Tocopherol As An Anti-Inflammatory Agent: Mechanistic Insights And Therapeutic Challenges, Megumi H Seese, Yuanzhong Xu

The Brown Foundation: Institute of Molecular Medicine

Vitamin E (alpha-tocopherol, αToc), an antioxidant fat-soluble vitamin that prevents lipid peroxidation and modulates pro-inflammatory cytokine production, is well-known to be critical for neuroprotection. However, the underlying mechanism remains poorly understood. Accumulating evidence demonstrates that αToc influences neuroinflammatory processes. Here, we review recent research progress on the effects of αToc on neuroinflammation. Preclinical studies included in this narrative review were identified through PubMed searches using the keywords "alpha-tocopherol AND neuroinflammation or alpha-tocopherol AND brain AND inflammation". While many studies support a neuroprotective role of αToc, the magnitude and direction of its effects vary substantially depending on dosage, route of administration, …

Dermal fibrosis is a cardinal feature of systemic sclerosis (SSc) for which there are limited Systemic sclerosis (SSc) is characterized by dermal fibrosis accompanied by loss of dermal white adipose tissue (DWAT), yet the mechanisms linking adipocyte depletion to fibroblast activation remain unclear. Here we identify the transcription factor SIX1 as a central regulator coupling adipogenic repression with profibrotic signaling. SIX1 expression was increased in skin biopsies from two independent SSc cohorts and localized to fibroblast and perivascular stromal cells. In mice, ubiquitous or adipocyte-specific deletion of Six1 preserved DWAT, reduced collagen accumulation, and selectively decreased pro-fibrotic mediators. In cultured …

The arcuate nucleus of the hypothalamus plays a central role in sensing and integrating nutritional, hormonal, and neural signals that regulate feeding, energy homeostasis, growth, and reproduction, all of which show pronounced sex differences. However, the cellular mechanisms underlying these responses remain poorly understood. We performed snRNA-seq of the mediobasal hypothalamus, focusing on the arcuate nucleus, in female and male mice under different nutritional states. Analysis of 42 cell types revealed that Agrp neurons were most sensitive to nutritional changes, dopaminergic neurons showed strong sex-specific differences, and KNDy neurons were highly responsive to both sex and nutrition. Pomc neurons displayed …

Propofol In Chronic Cannabis Users: A Mechanistic Link To Cannabinoid Hyperemesis?, Jonmark I. Dolendo, Sonia Frick, Jia Q. Yang, Brad A. Haubrich

Annual Research Symposium

Purpose: Cannabinoid hyperemesis syndrome (CHS) is characterized by cyclic nausea, vomiting, and abdominal pain in chronic cannabis users, often relieved by exposure to hot water. Propofol, a widely used GABAergic anesthetic with antiemetic properties, has paradoxically been implicated in exacerbating hyperemetic episodes in some cannabis users. With the growing legalization of marijuana and social acceptance to its recreational use it is believed that this phenomenon will be more ubiquitous to clinicians. This review aims to investigate the mechanistic and clinical evidence linking propofol administration to CHS and to summarize strategies for prevention, diagnosis, and management.

Methods: PubMed and EBSCO were …

The Adolescent Vaccination Program (AVP) guides pediatric clinics on how to implement evidence-based strategies to increase HPV vaccination rates. These strategies comprise the adoption of (1) immunization champions, (2) provider assessment and feedback, (3) continuing education, and (4) prompts, (5) parent reminders, and (6) parent education. The AVP systems-based intervention has demonstrated increased HPV vaccination rates in large urban pediatric clinic networks. The purpose of this study was to assess the feasibility of using an online decision support tool, the AVP Implementation Tool (AVP-IT), to …

Anti-Apoptotic Bcl-2 Binds To All Three Ip3r Isoforms, Thereby Limiting The Ca2+-Flux Properties Of Ip3r Homo-Tetramers, Ian De Ridder, Claire Cauwelier, Larry E Wagner Ii, Jens Loncke, Vikas Arige, Irina I Serysheva, David I Yule, Geert Bultynck

Faculty, Staff and Student Publications

Anti-apoptotic B-cell lymphoma 2 (BCL-2) controls inositol 1,4,5-trisphosphate receptor (IP3R)-mediated Ca²+ signalling. As cells typically express all three IP3R isoforms in variable abundances that assemble in hetero-tetrameric channels, the specific effects of BCL-2 on each isoform remain unclear. Here, we employed a reductionist approach using HEK293 cells triple-IP3R knockout reconstituted with a single IP3R isoform to elucidate the impact of BCL-2 on Ca2+ signalling by homo-tetrameric IP3R channels. Co-immunoprecipitation experiments demonstrated that BCL-2 interacts with each IP3R isoform. Live-cell Ca²+ imaging revealed that BCL-2 overexpression suppresses Ca²+ signals evoked by any of the three IP3R isoforms. Moreover, BCL-2 overexpression impaired …

Introduction: Treatment for childhood acute lymphoblastic leukemia (ALL) can result in hepatotoxicity. Despite being a common complication of ALL therapy, mechanisms and biomarkers of treatment-associated hepatotoxicity (TAH) are not well described.

Methods: We conducted lipidomic profiling to identify plasma lipids associated with TAH in children receiving ALL therapy utilizing a nested case-control framework. TAH was defined as (1) transaminitis: ALT/AST ≥ CTCAE grade 3, and/or (2) conjugated hyperbilirubinemia: > 3.0 mg/dL during induction therapy or > 2.0 mg/dL post induction. A total of 90 patients (45 matched pairs) treated at Texas Children's Hospital between 2012 and 2021 were selected for lipidomic profiling, …

Bergmann glia (BG) are a specialized glial population essential for cerebellar development, yet their developmental timeline and molecular identity in the human cerebellum remain poorly understood. Here, we combined detailed histopathological analysis with spatial transcriptomics and single-nucleus RNA sequencing to generate a developmental atlas of human cerebellar BG. Histology revealed that BG emerge around 11 post-conception weeks (PCW), initially serving as a scaffold for Purkinje cells (PCs) migrating into the PC layer of the cerebellar cortex. Following the establishment of a multilayered PC arrangement, BG form a distinct parallel layer separated from the PCs by the lamina dissecans (LD), with …

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest malignancies, with a 5-year survival rate of just 13%. While the development and early clinical use of small molecules targeting oncogenic KRAS mutations, key drivers of PDAC, have shown promise, resistance to these targeted therapies remains a significant challenge. We recently identified Syndecan-1 (SDC1), a highly expressed heparan sulfate proteoglycan, as a critical KRAS effector protein that promotes nutrient salvage and tumor growth. Here, we report the development of a human-specific monoclonal antibody (anti-SDC1 mAb) that inhibits PDAC cell proliferation in vitro and suppresses PDAC tumor growth in vivo. Mechanistically, …

Triple-negative breast cancer (TNBC) exhibits heterogeneous treatment responses, yet molecular subtypes based on predefined biological pathways show limited prognostic value. We introduce tumor-specific total mRNA expression (TmS), a pathway-agnostic deconvolution metric derived from matched RNA/DNA sequencing, as a robust stratification tool. Analyzing 575 TNBC patients across Western and East Asian populations, TmS outperforms established subtypes in predicting chemotherapy outcomes, stratifying patients into high TmS with favorable prognosis and low TmS with poor prognosis. Stromal enrichment with immune exclusion emerges as a universal feature of chemotherapy-resistant low-TmS tumors across all cohorts. Population-specific features distinguish Asian cohorts: high-TmS tumors exhibit cell cycle-driven …

Lymphatic Pumping Failure In The Arm Precedes Dermal Backflow And Breast Cancer-Related Lymphedema, Melissa B Aldrich, Meghan E Mcwain, Simona F Shaitelman, Rian E Kuhns, John C Rasmussen, Wendy A Woodward, Sarah M Desnyder, Wenyaw Chan, Eva M Sevick-Muraca

The Brown Foundation: Institute of Molecular Medicine

Background

Breast cancer patients who undergo regional nodal irradiation therapy (RNI) following neoadjuvant chemotherapy and mastectomy or lumpectomy with axillary lymph node dissection (ALND) frequently encounter breast cancer-related lymphedema (BCRL). Early detection and treatment can significantly improve outcomes. Previously, near-infrared fluorescence lymphatic imaging (NIRF-LI) detection of dermal backflow, or retrograde lymphatic flow into initial lymphatics, was shown to precede clinical BCRL diagnosis by 8–23 months. Herein, we hypothesize that lymphatic pump failure is responsible for dermal backflow and may be a target to prevent onset of BCRL symptoms.

Methods

Arm lymphatics in 51 patients with locally advanced breast cancer were …

When Nutrition Fails: Modeling Protein Malnutrition-Driven Vulnerability In Hepatic Drug Metabolism And Inflammatory Stress, Vijitha D. Kantety, Victor Jiminez Jr.

Annual Research Symposium

Background

Protein malnutrition remains a major global health problem and frequently co-occurs with alcohol use, opioid exposure, and infectious disease, particularly in low- and middle-income settings. The liver is central to both metabolism and inflammatory regulation, yet the effects of a malnutrition-like nutrient environment on hepatic responses to combined metabolic and inflammatory insults are not well defined. Cytochrome P450 3A4 (CYP3A4), a key enzyme involved in opioid metabolism, is highly sensitive to inflammatory signaling and may be especially vulnerable under conditions of nutritional deficiency. This project aims to 1) develop an in vitro model of nutritionally competent versus amino acid–restricted …

Strspy2.0: Unlocking The Potential Of Long Reads For Forensic Dna Profiling, Courtney L Hall, Rupesh K Kesharwani, Katherine E Mcbroom Henson, Bupe Kapema, Nicole R Phillips, Fritz J Sedlazeck, Roxanne R Zascavage

Faculty, Staff and Students Publications

Forensic human identification relies on length-based differences in short tandem repeats (STRs) across autosomal and Y chromosomes, which require separate reactions and provide limited resolution. While next-generation sequencing offers greater discriminatory power, most platforms are expensive and restricted to traditional lab settings. Nanopore sequencing has the potential to change this with the real-time, portable MinION sequencer. However, forensic-specific tools that generate STR profiles compatible with established length-based databases are lacking. To address this, we developed STRspy2.0, which simultaneously profiles autosomal and Y-STRs using nanopore reads. STRspy2.0 produced accurate profiles for 54 multiplexed control libraries and 41 mock casework samples (blood, …
