Chemical Biology Approaches For Tracking And Manipulation Of Macrophage Phenotypes, Javier A. Mas Rosario Oct 2022

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 …

The Role Of Calprotectin In T-Lymphocyte Driven Inflammation In A Mouse Model Of Psychological Trauma, Cassandra Moshfegh May 2022

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 May 2022

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 …


Effects Of Natural Products On Inflammation, Riley Ann Nadler Jan 2022

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 …
