Alcohol use disorder (AUD) causes executive dysfunction, leading to reduced treatment adherence, worse clinical outcomes, and relapse. Current medications do not address these symptoms. Targeting the neuroimmune interleukin-1 (IL-1) system has potential, but its mechanistic role in prefrontal cortex (PFC) dysfunction is unclear. Here we investigated how chronic alcohol consumption shifts IL-1 regulation of the rodent and non-human primate PFC. We found that alcohol drinking decreased reference memory and shifted the search strategy in mice of both sexes, and this deficit correlated with altered IL-1 receptor accessory protein (IL-1RAcP) mRNA levels in the medial PFC (mPFC) of male mice. Notably, …

Role Of Na⁺/K⁺-Atpase And Sodium–Calcium Exchanger In Digitoxin-Induced Cytotoxicity In Triple Negative Breast Cancer Cells, Alyson Sotomayor Quispe, Marilyn Odom Phd

SPARK Symposium Presentations

Triple Negative Breast Cancer (TNBC) is characterized by the absence of estrogen, progesterone, and HER2 receptors, limiting targeted treatment options. Digitoxin, a drug used to treat heart failure and atrial fibrillation through Na⁺/K⁺-ATPase inhibition, has demonstrated anticancer effects in TNBC cells, including apoptosis via the NF-κB pathway. This study investigates whether the Na⁺/K⁺-ATPase and sodium–calcium exchanger contribute to the mechanism of action of digitoxin in TNBC cells. We hypothesize that these transporters mediate digitoxin-induced cytotoxic effects. To test this, MDA-MB-468 cells were treated with digitoxin, and protein localization and expression were analyzed using immunofluorescence and Western blot. Digitoxin treatment resulted …

Γδ T Cells At The Interface Of Innate And Adaptive Immunity In Cancer, Arnau Solé Casaramona, Martin F Bachmann, Eva Sevick-Muraca, Mona O Mohsen

The Brown Foundation: Institute of Molecular Medicine

γδ T cells are unconventional lymphocytes that bridge innate and adaptive immunity by combining recognition of stress-induced ligands independently of classical major histocompatibility complex molecules with the capacity to undergo clonal expansion and long-term adaptation. Their unusual ability to detect malignant transformation using semi-invariant T-cell receptors, butyrophilin recognition and natural killer-like receptors positions them as powerful effector cells in tumors that evade classical immune escape mechanisms. Furthermore, distinct γδ subsets have distinct phenotyping and specific tissue-residencies, which could be leveraged to modulate immunological responses. We evaluate engineered therapies and different experimental platforms for studying γδ T cell biology. We conclude …

COVID-19 patients readily present with severe epithelial damage, such as tissue ulceration and erosion, along with disrupted tissue repair, in multiple organs. The mucous membranes of the lung alveoli [1, 2], gastrointestinal tract [3, 4], nasal [5] and oral cavity [6, 7] are the primary targets of the SARS-CoV-2 virus. The infected epithelium triggers a dysregulated immune response that further damages tissues and organs [8, 9–10]. Increasing evidence suggests that the SARS-CoV-2 virus can cause direct damage to epithelial cells and fibroblasts [11, 12–13]. Here, we report that the mucosa epithelia of COVID-19 patients can undergo cellular dedifferentiation before any …

Making Sense Of The Body: Cognitive Science, Disability, And Embodiment, Cheyne L. Joslin

USF Tampa Graduate Theses and Dissertations

The purpose of this project is to analyze different methodological approaches in the philosophy of cognitive science, with the goal of determining their usefulness for explaining and understanding bodily awareness and skill-acquisition over time. The examples of skill-acquisition are limited to motor control, impaired by various kinds of disability—but then acquired over time, via technological or rehabilitative means. These phenomena of motor learning are then viewed through the lens of two competing theoretical approaches in cognitive science: neuromechanical cognitive science, and radical enactivist cognitive science.

The strengths of the neuromechanical framework are found in its historical pedigree, and in the …
