This paper describes how lentils (Lens culinaris species) can positively affect health by reducing inflammation, providing antioxidants, and displaying antimicrobial properties. Lentils are rich in proteins, essential amino acids, minerals, and fibers, making them a valuable source of nutrition, particularly in low and middle-income countries. Lentils have many health benefits, including positive effects on diabetes management, support for cardiovascular health, and antioxidative properties. The antioxidative properties of lentils, attributed to their phenolic content, and their ability to inhibit inflammation-related enzymes are also discussed. We discuss the potential of lentils as a dietary tool in promoting immunity, reducing disease burdens, …

In the field of psychiatry, biological markers are rarely, if ever, used in the diagnosis of mental health disorders. Clinicians rely primarily on patient histories and behavioral symptoms to identify specific psychopathologies, which makes diagnosis highly subjective. Moreover, therapies for mental health disorders are aimed specifically at attenuating behavioral manifestations, which overlooks the pathophysiological indices of the disease. This is highly evident in posttraumatic stress disorder (PTSD) where inflammation and immune system perturbations are becoming increasingly described. Further, patients with PTSD possess significantly elevated risks of developing comorbid inflammatory diseases such as autoimmune and cardiovascular diseases, which are likely linked …

Background: Homoeopathic medicines are used extensively for the treatment of many human diseases and are shown to affect immune cell functions. However, our understanding of the immunomodulatory effects of such medicines and associated mechanisms of action remains limited. Objectives: The present study aims to investigate the immunomodulatory effects of Arsenic album, Rhus toxicodendron, Hepar sulphuris and Bryonia alba on lipopolysaccharide (LPS) induced peripheral blood neutrophils and monocytes. Materials and Methods: In this work, neutrophils and monocytes were treated with different homoeopathic dilutions of 30C potency separately, followed by stimulation with the LPS, to examine the immunomodulatory effects of these …
Erk Required For Lipopolysaccharide-Induced Tlr4 Internalization In Macrophages, Sara M. Reyna, Phoebe Fang-Mei Chang
Erk Required For Lipopolysaccharide-Induced Tlr4 Internalization In Macrophages, Sara M. Reyna, Phoebe Fang-Mei Chang
Research Symposium
Background: Insulin resistance is associated with low circulating levels of lipopolysaccharide (LPS). Binding of LPS to Toll like receptor 4 (TLR4) leads to the internalization and trafficking of TLR4 resulting in activation of downstream signaling pathways. TLR4 internalization in macrophages leads to the activation of pro-inflammatory signaling pathways and production of factors linked to the development of insulin resistance. The extracellular signal-regulated kinase 1 and 2 (ERK1 and 2) are activated downstream of TLR4 and are associated with insulin resistance. We hypothesized that ERK1 and ERK2 regulate TLR4 internalization in macrophages when exposed to LPS.
Methods: We examined whether inhibition …

Effects Of Interleukin-22 (Il-22) On Necroptosis, Inflammatory Responses, And Metabolism Of Mycobacterium Tuberculosis Stimulated Type 2 Diabetes Mellitus Mouse Macrophages, Bismark Owusu-Afriyie
Biotechnology Theses
Mycobacterium tuberculosis (Mtb) infects one-third of the world’s population and causes nearly 1.3 million deaths per year. Limited information is available about the immune responses during Mtb infection in type 2 diabetic hosts. Our laboratory developed an experimentally induced type 2 diabetes (T2DM) model in wild-type C57BL/6 mice and found that IL-22 and type 3 innate lymphoid cells (ILC3s) reduce inflammation and mortality of Mtb-infected T2DM mice. Our laboratory also found that Mtb-infected alveolar macrophages (AMs) from T2DM mice undergo necroptosis compared to Mtb-infected AMs of non-T2DM mice. In the current study, we determined whether …

Esophageal squamous cell carcinoma (ESCC) is a deadly disease with few prevention or treatment options. ESCC development in humans and rodents is associated with Zn deficiency (ZD), inflammation, and overexpression of oncogenic microRNAs: miR-31 and miR-21. In a ZD-promoted ESCC rat model with upregulation of these miRs, systemic antimiR-31 suppresses the miR-31-EGLN3/STK40-NF-κB-controlled inflammatory pathway and ESCC. In this model, systemic delivery of Zn-regulated antimiR-31, followed by antimiR-21, restored expression of tumor-suppressor proteins targeted by these specific miRs: STK40/EGLN3 (miR-31), PDCD4 (miR-21), suppressing inflammation, promoting apoptosis, and inhibiting ESCC development. Moreover, ESCC-bearing Zn-deficient (ZD) rats receiving Zn medication showed a 47% …

Immunomodulatory Effects Of Resolvin D2 In A Model Of Infection, Prem Yugandhar Kadiyam Sundarasivarao
Graduate School of Biomedical Sciences Theses and Dissertations
Dysregulated hyperinflammatory host immune response to underlying bacterial infections is a characteristic of sepsis. In sepsis, bacteria often trigger abnormal hyperinflammatory responses which can cause multiple organ failure and if sustained can lead to an immunosuppressive phase where the host is susceptible to secondary infections caused by opportunistic bacteria like Pseudomonas aeruginosa (P. aeruginosa). In our studies, we used a 2-hit model of cecal ligation and puncture (CLP) followed by P. aeruginosa secondary lung infection to investigate cellular and molecular mechanisms in the beneficial action of resolvin D2 (RvD2). Resolvins of the D-series are a group of fatty acids known …

Background
Posttraumatic stress disorder (PTSD) is a mental health condition triggered by exposure to traumatic events in an individual’s life. Patients with PTSD are also at a higher risk for comorbidities. However, it is not well understood how PTSD affects human health and/or promotes the risk for comorbidities. Nevertheless, patients with PTSD harbor a proinflammatory milieu and dysbiotic gut microbiota. Gut barrier integrity helps to maintain normal gut homeostasis and its dysregulation promotes gut dysbiosis and inflammation.
Methods
We used a mouse model of repeated social defeat stress (RSDS), a preclinical model of PTSD. Behavioral studies, metagenomics analysis of the …
Effects Of High-Speed Training On Messenger Rna Expression In Two-Year-Old Thoroughbred Racehorses, Mackenzie Grace Johnson
Effects Of High-Speed Training On Messenger Rna Expression In Two-Year-Old Thoroughbred Racehorses, Mackenzie Grace Johnson
Theses and Dissertations--Veterinary Science
Accumulating high-speed exercise has been identified as a significant risk factor for catastrophic injuries in racing Thoroughbreds. Injuries, regardless of severity, are a main cause of withdrawal from the racing industry, raising animal welfare concerns and resulting in significant economic losses. While most of the current literature focuses on catastrophic injuries incurred during racing rather than training, the present study aims to help fill this gap as well as discuss the associated risk factors. The evaluation of messenger RNA (mRNA) expression changes provides an efficient and straightforward approach to identifying horses at risk for catastrophic injury. While alternative injury risk …

INTRODUCTION: Inflammatory processes help protect the body from potential threats such as bacterial or viral invasions. However, when such inflammatory processes become chronically engaged, synaptic impairments and neuronal cell death may occur. In particular, persistently high levels of C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α) have been linked to deficits in cognition and several psychiatric disorders. Higher-order cognitive processes such as fluid intelligence (Gf) are thought to be particularly vulnerable to persistent inflammation. Herein, we investigated the relationship between elevated CRP and TNF-α and the neural oscillatory dynamics serving Gf.
METHODS: Seventy adults between the ages of 20-66 years …

In addition to hemostasis and thrombosis, blood platelets are involved in various processes such as inflammation, infection, immunobiology, cancer metastasis, wound repair and angiogenesis. Platelets' hemostatic and non-hemostatic functions are mediated by the expression of various membrane receptors and the release of proteins, ions and other mediators. Therefore, specific activities of platelets responsible for the non-hemostatic disease are to be inhibited while leaving the platelet's hemostatic function unaffected. Platelets' anti-aggregatory property has been used as a primary criterion for antiplatelet drugs/bioactives; however, their non-hemostatic activities are not well known. This review describes the hemostatic and non-hemostatic function of human blood …

Population ageing is a great achievement of humanity, but it also represents a challenge that the Western world is currently facing, as ageing is associated with increased susceptibility to age-related inflammatory diseases. Therefore, it is necessary to fully understand the mechanisms of healthy ageing to prevent the harmful aspects of ageing. The study of long living ndividuals (LLIs) is a great model for trying to achieve this goal. Accordingly, the oxy-inflammatory status of Sicilian LLIs was reviewed in the present paper. Based on the reported data, anti-inflammatory and anti-oxidative stress strategies have been discussed, useful for delaying or avoiding the …

Mako: NSU Undergraduate Student Journal
The coronavirus pandemic has presented a wide range of challenges for healthcare systems in the world. COVID-19 has infected millions of people, with approximately 90% of the population showing mild or no symptoms. The disease has some risk factors that increase its severity, such as obesity, age, diabetes, cardiovascular diseases, suppressed immune system, and pulmonary disorders. Obese individuals have higher chances of having symptomatic COVID-19 infection with excessive rates of hospitalization and ICU admission. Understanding the mechanisms defining the link between COVID-19 and obesity is necessary to develop preventive measures and therapeutic interventions for people with obesity. Patients with obesity …
Serpin-Derived Novel Peptide For The Treatment Against Hiv-Induced Inflammation In The Central Nervous System, Yemmy Soler
Serpin-Derived Novel Peptide For The Treatment Against Hiv-Induced Inflammation In The Central Nervous System, Yemmy Soler
FIU Electronic Theses and Dissertations
In the brain, HIV predominantly infects microglia/macrophages and astrocytes to a lesser extent. These cells form virus reservoirs with low levels of infection that are very hard to eradicate. Even though the use of cART increases survival rate in HIV patients, the virus persists as a chronic condition. cART is not able to effectively cross the BBB, control HIV replication, or attenuate inflammation in brain reservoirs. Therefore, the virus still causes neuronal dysfunction, pain-related pathology, and ultimately HAND. In this study, we decided to test the hypothesis that a serpin-derived small peptide, SP16, can serve as an anti-viral, anti-inflammatory, pro-survival, …

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 Effects Of Neuronal Growth Factors On Lps-Activated Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Angela Asirvatham Ph.D.
Student Research Poster Presentations 2022
Schwann cells (SCs) are the principal support cells of neurons in the peripheral nervous system, that both myelinate axons for the rapid conduction of electrical impulses as well as assist in axonal repair during nerve injury. During nerve injury, SCs secrete tumor necrosis factor alpha (TNF-α)1,5,6 and other proinflammatory mediators1,6, attracting macrophages to the site of injury to induce inflammation and clear myelin debris.1,6 Once the debris is cleared, the neuron stimulates SC proliferation by secreting neuronal mitogens, such as heregulin3,4, and an unknown factor that activates the cAMP pathway3, an important …

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn Henry, Peyton Kimmel, Angela Asirvatham
Student Research Poster Presentations 2022
During peripheral nerve injury, the myelin surrounding the neuronal axons is damaged, initiating an inflammatory response to remove myelin debris. Once myelin debris is cleared, Schwann cells acquire a proliferating phenotype which allows them to grow and divide so that remyelination can occur. The neuron stimulates Schwann cell division by secreting growth factors, like heregulin, and an unknown growth factor that activates the cAMP pathway. Although the role of cAMP in axonal regeneration is well-known, not much has been explored about its function in Schwann cells during nerve injury and inflammation. To simulate an inflammatory environment, the S16 Schwann cell …

The nuclear receptor PPARα is associated with reducing adiposity, especially in the liver, where it transactivates genes for β-oxidation. Contrarily, the function of PPARα in extrahepatic tissues is less known. Therefore, we established the first adipose-specific PPARα knockout (PparaFatKO) mice to determine the signaling position of PPARα in adipose tissue expansion that occurs during the development of obesity. To assess the function of PPARα in adiposity, female and male mice were placed on a high-fat diet (HFD) or normal chow for 30 weeks. Only the male PparaFatKO animals had significantly more adiposity in the inguinal white …

Autosomal dominant polycystic kidney disease (PKD) is a hereditary disorder affecting multiple organs, including the heart. PKD has been associated with many cardiac abnormalities including the arrhythmogenic remodeling in clinical evaluations. In our current study, we hypothesized that Pkd2 gene mutation results in structural and functional defects in the myocardium. The structural and functional changes of Pkd2 mutant hearts were analyzed in the myocardial-specific Pkd2 knockout (KO) mouse. We further assessed a potential role of TGF-b1 signaling in the pathology of Pkd2-KO hearts. Hearts from age-matched 6-month-old MyH6•Pkd2wt/wt (control or wild-type) and MyH6 …

Nowadays, the incidence of obesity is a global challenge and it is estimated that the total number of overweight and obese adults will increase up to 1.35 billion by 2030. Evidence obtained from clinical and experimental studies shows that obesity may be associated with cognitive performance and executive function impairments. Considering various evidence for the poor episodic memory tasks and verbal learning as well as the destruction of cortical gray matter in the obese individuals, here, we collected some causal pathways for contribution of inflammation, oxidative stress, insulin resistance, and hypertension in the development of brain disorders in obesity.

Anti-viral monoclonal antibody (mAb) treatments may provide immediate but short-term immunity from coronavirus disease 2019 (COVID-19) in high-risk populations, such as people with diabetes and the elderly; however, data on their efficacy in these populations are limited. We demonstrate that prophylactic mAb treatment blocks viral replication in both the upper and lower respiratory tracts in aged, type 2 diabetic rhesus macaques. mAb infusion dramatically curtails severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-mediated stimulation of interferon-induced chemokines and T cell activation, significantly reducing development of interstitial pneumonia. Furthermore, mAb infusion significantly dampens the greater than 3-fold increase in SARS-CoV-2-induced effector CD4 …
Does Epa Cause A Decrease In Inflammation Of Bend.3 Cells Through Ffar4?, Clay J. Weidenhamer
Does Epa Cause A Decrease In Inflammation Of Bend.3 Cells Through Ffar4?, Clay J. Weidenhamer
Masters Theses
Atherosclerosis is an inflammatory disease initiated by low and oscillatory shear stress on the endothelium. The inflammatory process recruits leukocytes to the vessel wall by expression of the adhesion molecule VCAM-1. Activation of the NF-κB inflammatory signaling pathway is responsible for the increase in VCM-1 expression. Omega 3 FAs, such as EPA, reduce the risk of atherosclerosis by decreasing this inflammatory response. The pathway by which omega 3 FAs is proposed to inhibit inflammation includes activating FFAR4 to decrease NF-κB activation thereby reducing expression of adhesion molecules. We hypothesized that treatment of endothelial cells with 30 μM EPA would decrease …

BACKGROUND: Activation of intravesical protease activated receptor 4 (PAR4) leads to release of urothelial macrophage migration inhibitory factor (MIF). MIF then binds to urothelial MIF receptors to release urothelial high mobility group box-1 (HMGB1) and elicit bladder hyperalgesia. Since MIF binds to multiple receptors, we investigated the contribution of individual urothelial MIF receptors to PAR4-induced HMGB1 release in vivo and in vitro and bladder pain in vivo.
METHODOLOGY/PRINCIPAL FINDINGS: We tested the effect of intravesical pre-treatment with individual MIF or MIF receptor (CD74, CXCR4, CXCR2) antagonists on PAR4-induced HMGB1 release in vivo (female C57/BL6 mice) and in vitro (primary …

β cells may participate and contribute to their own demise during Type 1 diabetes (T1D). Here we report a role of their expression of Tet2 in regulating immune killing. Tet2 is induced in murine and human β cells with inflammation but its expression is reduced in surviving β cells. Tet2-KO mice that receive WT bone marrow transplants develop insulitis but not diabetes and islet infiltrates do not eliminate β cells even though immune cells from the mice can transfer diabetes to NOD/scid recipients.

Dissertations & Theses (Open Access)
Inflammation is a major risk factor for pancreatic ductal adenocarcinoma. When occurring in the context of pancreatitis, mutations of KRAS accelerate tumor development. We discovered that long after its complete resolution, a transient inflammatory event primes pancreatic epithelial cells to subsequent transformation by oncogenic KRAS. Upon recovery from acute inflammation, epithelial cells of the pancreas display an enduring adaptive response associated with sustained transcriptional and epigenetic reprogramming. Such adaptation enables the prompt reactivation of acinar-to-ductal metaplasia (ADM) upon subsequent inflammatory events, thus efficiently limiting tissue damage via rapid decrease of zymogen production. We propose that since activating mutations of KRAS …
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
MSU Graduate Theses
Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …
