Rumen-Protected Methionine Supplementation Improves Lactation, Oxidative Status, And Immune Response During A Subclinical Mastitis Challenge In Lactating Dairy Cows., Anita Paz Lopez

Electronic Theses and Dissertations

Mastitis is a significant problem in the dairy industry, posing numerous challenges for dairy farmers worldwide. Mastitis refers to the inflammation of the mammary gland, primarily caused by bacterial infections. This condition affects the health and well-being of dairy cows and has severe economic implications for farmers and overall dairy production. The prevalence of mastitis substantially threatens milk quality, productivity, and profitability, making it a top concern in the dairy industry. Preventing mastitis in cows is crucial for maintaining the herd's health and ensuring highquality milk production. Nutritional strategies have recently gained greater attention due to a direct impact on …


Immunomodulation Of Myeloid-Derived Suppressor Cells By Particulate B-Glucan In Cancer., Sabrin Husein Albeituni Dec 2015

Immunomodulation Of Myeloid-Derived Suppressor Cells By Particulate B-Glucan In Cancer., Sabrin Husein Albeituni

Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature myeloid cells that promote tumor progression. In this study, we investigated the effect of dectin-1 stimulation by yeast-derived particulate β-glucan in MDSC function and differentiation in cancer. In vivo treatment of mice bearing lewis lung carcinoma and mammary cell carcinoma with particulate β-glucan decreased tumor weight and splenomegaly, and reduced the accumulation of polymorphonuclear-MDSC (PMN-MDSC) but not monocytic-MDSC (M-MDSC) in the spleen and tumor. In addition, particulate β-glucan differentially modulated the function of different MDSC subsets; it enhanced PMN-MDSC respiratory burst and apoptosis, and induced the differentiation of M-MDSC into …
