The gut–brain axis represents a dynamic two-way signaling network whose dysregulation has been implicated in a wide range of neurogastrointestinal disorders. In this context, extracellular vesicles (EVs) have emerged as critical mediators of intercellular signaling and as promising non-invasive biomarkers. Derived from host and microbial cells, EVs carry bioactive cargo—including proteins, lipids, nucleic acids, and metabolites—that reflect the physiological or pathological state of their cells of origin. Their ability to cross biological barriers, such as the blood–brain barrier, underscores their potential for diagnosing and monitoring gut–brain axis dysfunctions. In this mini-review, we integrate microbial and brain-derived EVs within the framework …

Isg15 Dysregulates Endoplasmic Reticulum-Mitochondrial Contacts And Calcium Homeostasis In Ataxia Telangiectasia, Oygul Mirzalieva, Ryan E. Reed, Arthur L. Haas, Meredith A. Juncker, Patrick Logarbo, Jennifer M. Klein, David Worthylake, Shyamal D. Desai

School of Graduate Studies Faculty Publications

Dysregulation of endoplasmic reticulum and mitochondrial (ER:Mit) contacts and mitochondrial calcium (mitCa2+) homeostasis are found in several neurodegenerative disorders, including Ataxia Telangiectasia (A-T). However, the cellular basis of these defects remains unclear. Previously, we demonstrated that the aberrantly elevated Interferon-Stimulated Gene 15 (ISG15) pathway inhibits protein polyubiquitylation, its dependent protein turnover, and mitophagy pathways in A-T. Literature indicates that silencing of mitochondrial ubiquitin ligase 1 (MUL1) stabilizes mitofusin2 (MFN2) and attenuates mitCa2+ uptake from ER to Mit (mitCa2+influx) in primary neurons. We have replicated these findings in apparently healthy fibroblasts. We hypothesized that elevated ISG15 may inhibit ubiquitin-dependent MUL1-mediated degradation …


Osteoprogenitor Cells From Non-Regenerative Bone Show Greater Resistance To Cellular Stress Than Those From Regenerative Bone, Joshua Broussard, Sylvia Culpepper, Tyrel Long, Alexander J. Trostle, Robert J. Tower, Mimi C. Sammarco, Jennifer Simkin Dec 2025

Osteoprogenitor Cells From Non-Regenerative Bone Show Greater Resistance To Cellular Stress Than Those From Regenerative Bone, Joshua Broussard, Sylvia Culpepper, Tyrel Long, Alexander J. Trostle, Robert J. Tower, Mimi C. Sammarco, Jennifer Simkin

School of Medicine Faculty Publications

INTRODUCTION: Bone regeneration following injury depends on osteoprogenitor cells derived predominantly from the periosteum. Incomplete regeneration has been attributed to both cell-extrinsic factors (e.g., environment, inflammation, mechanical instability) and cell-intrinsic factors (e.g., impaired proliferation or differentiation of stem cells). In the digit amputation mouse model, amputation through the third phalanx (P3) supports complete regeneration, while amputation through the second phalanx (P2) results in callus formation and scarring. Periosteal cells are known to be the major contributing cell source for repair and regeneration. Yet the healing outcomes of P2 and P3 amputations are significantly different. This study tests whether P2 and …

School of Dentistry Faculty Publications

Trained immunity is a long-term functional reprogramming of innate cells that allows for the formation of immune memory akin to adaptive responses, but with a more rapid nonspecific response. We recently identified an anti-inflammatory trained immunity response, termed trained tolerogenic immunity (TTI), induced by low virulence Candida dubliniensis, that protects against acute lethal polymicrobial sepsis via myeloid-derived suppressor cells (MDSCs). Trained immunity and MDSCs arise following hematopoietic stem and progenitor cell (HSPC) expansion in the bone marrow. Here, we show that C. dubliniensis induces inoculum-dependent protection and HSPC expansion, whereas depletion of HSPCs following C. dubliniensis immunization abrogates protection. We …

School of Graduate Studies Faculty Publications

Dopamine (DA) midbrain neurons are involved in a wide array of key brain functions including movement control and reward-based learning. They are also critical for major brain disorders such as Parkinson's disease or schizophrenia. DA neurons projecting to distinct striatal territories are diverse with regard to their molecular makeup and cellular physiology, which are likely to contribute to the observed differences in temporal DA dynamics. Among these regions, the dorsolateral striatum (DLS) displays the fastest DA dynamics, which might control the moment-to-moment vigor and variability of voluntary movements. However, the underlying mechanisms for these DLS-specific fast DA fluctuations are unresolved. …

During development, brain regions follow encoded growth trajectories. Compared to classical brain growth charts, high-definition growth charts could quantify regional volumetric growth and constituent cell types, improving our understanding of typical and pathological brain development. Here, we create high-resolution 3D atlases of the early postnatal mouse brain, using Allen CCFv3 anatomical labels, at postnatal days (P) 4, 6, 8, 10, 12, and 14, and determine the volumetric growth of different brain regions. We utilize 11 different cell type-specific transgenic animals to validate and refine anatomical labels. Moreover, we reveal region-specific density changes in γ-aminobutyric acid-producing (GABAergic) neurons, cortical layer-specific cell …

Acetaminophen (ApAP) toxicity arises from the reactive intermediate N-acetyl-p-benzoquinone imine (NAPQI), a degradation product known to cause significant liver damage and kidney injury. This toxicity is a major concern associated with the widespread use of ApAP, a commonly used nonsteroidal anti-inflammatory drug. To address this important issue, a series of novel nonopioid analgesic candidates with reduced toxicity have been recently reported. However, the molecular and atomic-level mechanisms underlying their decreased toxicity remain largely unexplored. In this study, computational analyses is performed to investigate the dynamic behavior, physicochemical properties, and ligand-receptor interactions of these new chemical entities (NCEs). The findings provide …

Extracellular matrix (ECM) components are key regulators in breast cancer progression, as ECM remodeling is essential for breast cancer cells to invade into surrounding tissue. This process is characterized by the alignment of fibrillar collagens, breakdown of basement membrane components, and increased interstitial collagen stiffness. In patients with obesity, pre-existing ECM changes, including excessive collagen deposition and heightened matrix stiffness, mimic alterations detected in breast cancer. Given that obesity is a predictor of poor prognosis and resistance to treatment in breast cancer, it is crucial to understand how ECM conditioned by obesity affects disease outcomes.

Fiber’s effect on our gut microbes has been studied extensively, while knowledge of the effect of protein is sparse. Colonic putrefaction of dietary protein is known to produce several potentially detrimental compounds. This randomized controlled trial (RCT) uses a pre- and post-study design to investigate the effect of consuming higher levels of dietary protein on the gut microbiota and the metabolites it produces. Here, we describe our virtual recruitment efforts and RCT protocol. Potential participants lived throughout the contiguous US. Several recruitment methods were employed, of which email reached the largest group of people (approximately 9,100) and generated a 0.3% …
