Chronic multisymptom illness (CMI) affects a subsection of elderly and war Veterans and is associated with systemic inflammation. Here, using a mouse model of CMI and a group of Gulf War (GW) Veterans' with CMI we show the presence of an altered host resistome. Results show that antibiotic resistance genes (ARGs) are significantly altered in the CMI group in both mice and GW Veterans when compared to control. Fecal samples from GW Veterans with persistent CMI show a significant increase of resistance to a wide class of antibiotics and exhibited an array of mobile genetic elements (MGEs) distinct from normal …

Recognition of pathogen-or-damage-associated molecular patterns is critical to inflammation. However, most pathogen-or-damage-associated molecular patterns exist within intact microbes/cells and are typically part of non-diffusible, stable macromolecules that are not optimally immunostimulatory or available for immune detection. Partial digestion of microbes/cells following phagocytosis potentially generates new diffusible pathogen-or-damage-associated molecular patterns, however, our current understanding of phagosomal biology would have these molecules sequestered and destroyed within phagolysosomes. Here, we show the controlled release of partially-digested, soluble material from phagolysosomes of macrophages through transient, iterative fusion-fission events between mature phagolysosomes and the plasma membrane, a process we term eructophagy. Eructophagy is most active …

BACKGROUND: Bacterial vaginosis might increase HIV risk by eliciting genital inflammation and epithelial barrier disruption, whereas vaginal Lactobacillus crispatus is associated with immune quiescence and HIV protection. We investigated the effect of a live biotherapeutic containing L crispatus CTV-05 (LACTIN-V) on genital immunology and key vaginal bacteria.
METHODS: This substudy included women aged 18-45 years who participated in the randomised, placebo-controlled, phase 2b trial of LACTIN-V to reduce bacterial vaginosis recurrence, conducted at four universities and hospitals in the USA. Women with negative results for sexually transmitted infection, pregnancy, and urinary tract infection were provided a 5-day course of vaginal …

The Role Of Calprotectin In T-Lymphocyte Driven Inflammation In A Mouse Model Of Psychological Trauma, Cassandra Moshfegh
Theses & Dissertations
Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder that affects nearly 45 million Americans. This mental disorder is characterized by behavioral symptoms such as learned helplessness, hyperarousal, withdrawal, and flashbacks. The deleterious effects of PTSD are far-reaching and go beyond behavioral dysfunction, as these individuals are at a three-fold higher risk of comorbid inflammatory diseases. Autonomic, metabolic, and cardiovascular diseases plague these individuals later in their lifetime, however, the mechanistic link connecting psychological trauma to this systemic peripheral immunological dysfunction remains elusive. T-lymphocyte-induced inflammation plays a significant role in all these disease pathologies. Previous work from our laboratory demonstrated …

Reno-Protective And Immune Effects Of Growth Differentiation Factor 15 In Obesity-Related Kidney Disease, Jessie T. Sullivan
Honors Thesis
According to the World Health Organization, worldwide obesity has tripled since 1975 and is still on the rise, putting people at a higher risk of some cardiovascular diseases and kidney disease. Growth differentiation factor 15 (GDF15) is a stress-responsive cytokine that has been studied recently for its role in multiple biological processes and diseases. The member of the transforming growth factor beta (TGF-b) family has been investigated as a therapeutic agent and biomarker for obesity and associated cardiovascular diseases, stroke, diabetes, osteoarthritis, cancer, and kidney disease. Studies have shown the anti-inflammation, anti-obesity, and anti-diabetic effects of GDF15, but few have …

Multisystem inflammatory syndrome in children (MIS-C) is a severe hyperinflammatory condition characterized by fever, systemic inflammation, and multiorgan dysfunction that manifests late in the course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). MIS-C generally occurs 2 to 6 weeks after SARS-CoV-2 infection. The incidence of MIS-C is unknown, although it appears to occur in less than 1 percent of children with confirmed SARS-CoV-2 infection. MIS-C has overlapping clinical features of toxic shock syndrome and Kawasaki disease, although the pathogenesis is unclear. Epidemiologists, researchers, and clinicians are struggling to describe and characterize the disease phenomenon while treating patients at the …

As the gateway to the respiratory system, the oral cavity can play an essential role in SARS-CoV-2 invasion and transmission. Besides high expression of angiotensin‐converting enzyme 2 (ACE2), the oral cavity can harbor viral particles in saliva, gingival crevicular fluid, and the periodontal pocket. Microbial and inflammatory associations closely link periodontitis and COVID-19. In this review, we summarize the possible oral manifestations of COVID‐19, its association with periodontal diseases, the plausible underlying mechanisms of microbial and inflammatory crosstalk between COVID‐19 and periodontal diseases, and mitigation protocols during periodontal treatment.

Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian Gilbert
Animal Science Undergraduate Honors Theses
Lipoteichoic acid (LTA) is component of the cell wall of Gram-positive bacteria that stimulates inflammation during bacterial infection. However, few studies have investigated the in vivo immune response to LTA, and none of the in vivo studies done have been performed in birds. For this project, the pulp (a skin-derivative) of growing feathers (GFs) of chickens were used as a test site to investigate the in vivo effects of intradermally injected LTA. In Study 1, the pulp of 12 GFs of 11-week-old Light-brown Leghorn (LBL) males were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 …

The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen
Electronic Theses and Dissertations
Early-onset colon cancer (EOCC) is a leading cause of cancer death among people younger than 50 years of age in the United States and is associated with metabolic dysfunction and obesity. Anti-inflammatory tumor-associated macrophages (TAM) and low Peroxisome Proliferator Activated Receptor Gamma (PPARγ) gene expression in colon cancer (CC) tissue promote tumor progression and decreased patient survival. Obesity-related hormones, such as leptin and adiponectin, have the potential to affect gene expression in TAM to promote CC progression and thereby link obesity and EOCC. The aim of this project was to identify target genes in human CC and to investigate the …

As the total number of people living with HIV continues to rise across the world, an effective HIV treatment is still sought after. While modern-day advanced therapies exist for mitigating much of the negative effects of HIV, the virus remains evasive and problematic in the central nervous system. Thus, even with treatment, many people living with HIV continue to suffer from a plethora of symptoms. However, a large proportion of HIV-positive patients claim to feel a reduction in those persevering symptoms after cannabis usage. This anecdotal evidence has sparked interest in the efficacy of cannabis constituents for HIV therapy. This …

Patients with mutations in HOIL1 experience a complex immune disorder including intestinal inflammation. To investigate the role of HOIL1 in regulating intestinal inflammation, we employed a mouse model of partial HOIL1 deficiency. The ileum of HOIL1-deficient mice displayed features of type 2 inflammation including tuft cell and goblet cell hyperplasia, and elevated expression of Il13, Il5 and Il25 mRNA. Inflammation persisted in the absence of T and B cells, and bone marrow chimeric mice revealed a requirement for HOIL1 expression in radiation-resistant cells to regulate inflammation. Although disruption of IL-4 receptor alpha (IL4Rα) signaling on intestinal epithelial cells ameliorated tuft …
10-Minute Ebd: Preferred Analgesia For Orthodontic Tooth Movement: Acetaminophen Or Nsaids?, Ryan N. Mcgovern
10-Minute Ebd: Preferred Analgesia For Orthodontic Tooth Movement: Acetaminophen Or Nsaids?, Ryan N. Mcgovern
The Journal of the Michigan Dental Association
This 10-Minute EBD column explores the choice between acetaminophen and NSAIDs for managing pain during orthodontic tooth movement. The author presents a scenario involving a patient's discomfort after archwire adjustment and delves into the impact of tooth movement on the periodontium. The PICO question focuses on the effectiveness of NSAIDs and acetaminophen in controlling discomfort without impeding tooth movement. The literature search reveals varying recommendations on analgesics, with some studies favoring acetaminophen. The evidence suggests that acetaminophen and short-term celecoxib are suitable choices for orthodontic analgesia. However, caution is advised in extrapolating findings from animal studies to human conditions.

Background: Low-density neutrophils (LDN) are increased in several inflammatory diseases and may also play a role in the low-grade chronic inflammation associated with obesity. Here we explored their role in obesity, determined their gene signatures, and assessed the effect of bariatric surgery. Methods: We compared the number, function, and gene expression profiles of circulating LDN in morbidly obese patients (MOP, n=27; body mass index (BMI) > 40 Kg/m2) and normal-weight controls (NWC, n=20; BMI < 25 Kg/m2) in a case-control study. Additionally, in a prospective longitudinal study, we measured changes in the frequency of LDN after bariatric surgery (n=36) and tested for associations with metabolic and inflammatory parameters. Findings: LDN and inflammatory markers were significantly increased in MOP compared to NWC. Transcriptome analysis showed increased neutrophil-related gene expression signatures associated with inflammation, neutrophil activation, and immunosuppressive function. However, LDN did not suppress T cells proliferation and produced low levels of reactive oxygen species (ROS). Circulating LDN in MOP significantly decreased after bariatric surgery in parallel with BMI, metabolic syndrome, and inflammatory markers. Interpretation: Obesity increases LDN displaying an inflammatory gene signature. Our results suggest that LDN may represent a neutrophil subset associated with chronic inflammation, a feature of obesity that has been previously associated with the appearance and progression of co-morbidities. Furthermore, bariatric surgery, as an efficient therapy for severe obesity, reduces LDN in circulation and improves several components of the metabolic syndrome supporting its recognized anti-inflammatory and beneficial metabolic effects.

There is limited evidence for the effects of diet on cardiometabolic profiles during the pubertal transition. We collected repeated measures of diet quality and cardiometabolic risk factors among Mexican youth. This analysis included 574 offspring of the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENT) birth cohort followed up to three time points. Dietary Approaches to Stop Hypertension (DASH), alternate Mediterranean Diet (aMedDiet), and Children’s Dietary Inflammatory Index (C-DIITM) scores were computed from food frequency questionnaires. Higher DASH and aMedDiet scores reflect a higher diet quality, and lower C-DII scores reflect an anti-inflammatory diet. Cardiometabolic risk factors …

International Journal of Exercise Science: Conference Proceedings
PURPOSE: Previous research has shown that different phases of the menstrual cycle may impact biometrics such as markers of stress and inflammation [e.g., cortisol (CORT), interleukin-6] as well as body composition. However, there is scarce literature regarding markers of stress and oxidative stress such as salivary a-amylase (sAA), immunoglobin-A (SIgA) and uric acid (UA), in relation to the four different menstrual phases. The purpose of this study was to examine the impact of menstrual phases on sAA, CORT, UA and SIgA. METHODS: 21 pre-menopausal women with regular menstrual cycles (n=9) oral contraceptive users (OC) and ( …

Electronic Thesis and Dissertation Repository
Kidney transplantation remains the optimal treatment option for patients with end-stage renal disease. We aim to improve organ preservation during transplantation by reducing damage from ischemia reperfusion injury (IRI) using existing clinically approved drugs. In this study, we developed and characterized an in vitro model that mimics the conditions of IRI in kidney transplant as a tool to screen and study the therapeutic effect of drugs in the context of IRI. We recapitulated several key outcomes in IRI in our model, including the induction of hypoxia, cell death, increased expression of damage markers (NGAL, HMBG-1) and pro-inflammatory cytokines in a …

Introduction: Short chain fatty acids (SCFA) are gut microbiota-derived metabolites that contribute to the gut-brain axis and may impact stroke outcomes following gut dysbiosis. We evaluated plasma SCFA concentrations against stroke severity parameters and identified SCFA-associated protein networks.
Methods: The Blood and Clot Thrombectomy Registry and Collaboration (BACTRAC), a continuously enrolling tissue bank, was used to obtain stroke samples. Arterial blood distal and proximal to the thrombus was obtained from Acute Ischemic Stroke (AIS) Patients (n=53) during thrombectomy. Patient demographics, stroke presentation and outcome parameters were reported. The SCFAs were isolated from proximal plasma via chemical derivatization UHPLC coupled tandem …

Exercise is commonly prescribed as a lifestyle treatment for chronic metabolic diseases as it functions as an insulin sensitizer, cardio-protectant, and essential lifestyle tool for effective weight maintenance. Exercise boosts the production of reactive oxygen species (ROS) and subsequent transient oxidative damage, which also upregulates counterbalancing endogenous antioxidants to protect from ROS-induced damage and inflammation. Exercise elevates heme oxygenase-1 (HO-1) and biliverdin reductase A (BVRA) expression as built-in protective mechanisms, which produce the most potent antioxidant, bilirubin. Together, these mitigate inflammation and adiposity. Moderately raising plasma bilirubin protects in two ways: (1) via its antioxidant capacity to reduce ROS and …
