Migration Of Myeloid-Derived Suppressor Cells To Tumor And Tumor-Draining Lymph Node In A Murine Model Of Breast Cancer, Vyara Matson

Theses and Dissertations

Myeloid-derived suppressor cells (MDSC) consist of two major subsets, monocytic MDSC (M-MDSC) and polymorphonuclear MDSC (PMN-MDSC), both of which expand in cancer and suppress the activation of naïve T cells in the tumor-draining lymph node (TDLN) and the function of effector T cells in the tumor microenvironment. Thus, the ability of MDSC to enter the TDLN and the tumor is likely to be critical for suppression of the anti-tumor immune response. L-selectin mediates the homing of circulating naïve lymphocytes to lymph nodes and the migration of conventional myeloid cells, such as neutrophils and monocytes, to sites of inflammation, but its …

The Effects Of 830nm Light On Inflammation In Retinitis Pigmentosa, Krystal Marie Bach

Theses and Dissertations

Purpose: Retinitis Pigmentosa (RP) is an inherited retinal degenerative disease and the most common cause of blindness in developed countries, affecting approximately 1 in 4,000 people. RP is characterized by photoreceptor cell death and recent studies suggest that chronic inflammation may play a key role in the pathogenesis of RP. Currently, there are no known treatments or preventive measures to delay or halt the loss of photoreceptor cells. Photobiomodulation (PBM) by light in the far-red or near-infrared (NIR) range of the light spectrum has been documented to help promote cell survival and reduce inflammation in several disease states. Recent studies …

The Mechanism Of Suppression By A Protective Peptide In A Mouse Model Of Multiple Sclerosis, Alaa Mansour Almatrook

Theses and Dissertations

Multiple Sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS). MS is characterized by an immune response directed against myelin sheath. This immune response results in demyelination, which leads to the clinical symptoms of MS. It is accepted that MS is mediated by T helper 1/ T helper 17 immune responses. However, the role of B cells and antibodies (Abs) are still under debate. The primary animal model for MS is the experimental autoimmune encephalomyelitis (EAE) that is induced by immunizing animals with one of the myelin components. We previously showed that immunizing mice with the …

Impaired T Lymphocyte Responses In Older Macaques: Possible Implications For Lentiviral Disease Progression, Sopitsuda Bunnag

Theses and Dissertations

Lentiviral infections of humans and rhesus macaques result in acquired immunodeficiency almost invariably. Yet the duration between the initial infection and the onset of generalized failure of the immune system varies between subjects, in both organisms. Furthermore, acquiring the infection at an older age tends to accelerate disease progression, but mechanisms underlying the latter phenomenon have not been elucidated. It is widely accepted that the events that take place during the very early stages of infection play a critical role in determining disease progression. During this brief period, a fierce competition between viral virulence mechanisms and host immune defenses takes …

Effects Of 670 Nm And 830 Nm Light On The Immune Response To Borrelia Burgdorferi, Felice Chen

Lyme arthritis is a debilitating joint disorder that arises from Lyme disease, which is a result of infection by the spirochete Borrelia burgdorferi. Antibiotics are the traditional treatment for Lyme disease, but chronic arthritis may persist in some patients despite antibiotic treatment. Therefore, other forms of treatment for Lyme arthritis are needed. Photobiomodulation (PBM) using red or near-infrared light, with wavelengths between 630 …
