Chemical Biology Approaches For Tracking And Manipulation Of Macrophage Phenotypes, Javier A. Mas Rosario
Chemical Biology Approaches For Tracking And Manipulation Of Macrophage Phenotypes, Javier A. Mas Rosario
Doctoral Dissertations
Macrophages are white blood cells of the innate immune system that have the ability to change phenotypically depending on the stimuli present in their surroundings through a process commonly referred to as polarization. Macrophage phenotypes broadly range from pro-inflammatory, anti-tumor (M1) to immune-suppressing (M2). Of particular interest to this work, breast cancer progression and metastasis rely on the presence of M2-like tumor-associated macrophages (TAMs). While many studies have shown the involvement of macrophages in tumor progression and metastasis, there remains a need to further explore these interactions and the polarization process, including tracking of macrophage subtypes. Toward this end, I …

Obesity As A Risk Factor For Covid-19, Gabriela Hermes, Mir Saleem
Obesity As A Risk Factor For Covid-19, Gabriela Hermes, Mir Saleem
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, …
The Role Of Calprotectin In T-Lymphocyte Driven Inflammation In A Mouse Model Of Psychological Trauma, Cassandra Moshfegh
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 …
Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian Gilbert
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 …
Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham
Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham
SURF Posters 2022
Schwann cells are a type of glial cell in the peripheral nervous system that produce the myelin sheath surrounding neuronal axons. This myelin insulates the neurons and promotes the rapid conduction of electrical impulses throughout the body. Schwann cells have also been found to play a critical role in neuron repair following nerve injury. During nerve injury, the myelin sheath is damaged, stimulating Schwann cells to release cytokines, or inflammatory mediators, that recruit immune cells to the site of injury so that the myelin debris can be cleared, and repair can take place.1 Then neuronal growth is facilitated by heregulin …

Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian M. Gilbert, Jossie M. Santamaria, Gisela F. Erf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Lipoteichoic acid (LTA) is a cell-wall polymer in Gram-positive bacteria that stimulates inflammation. Few studies have investigated in vivo immune response to LTA, and none of the in vivo studies have been performed in birds. For this project, the pulp (a skin derivative) of growing feathers (GF) of chickens was used to investigate the in vivo effects of intradermally injected LTA. In Study 1, GF of chickens were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 or 250 μg LTA/mL; 3 chickens/dose). Growing feathers were plucked before injection (0 h) and at 6, 24, 48, …
Effects Of Natural Products On Inflammation, Riley Ann Nadler
Effects Of Natural Products On Inflammation, Riley Ann Nadler
MSU Graduate Theses
Chronic inflammation is characterized by infiltration of inflammatory cells such as macrophages and lymphocytes into the tissue where they produce inflammatory cytokines that contribute to tissue damage. Worldwide, 3 out of 5 people die due to chronic inflammatory diseases like cardiovascular diseases, obesity, diabetes, and cancer. Since it is well-documented that diet and metabolism are key mediators of inflammation, I investigated the effects of dietary lectins on inflammatory cytokine production and the ability of sodium pyruvate, a metabolite, to decrease inflammation. In chapter 1, I examined the effect that lectins from either Triticum vulgaris (common wheat) or Phaseolus vulgaris (common …
