Functional Impact Of Ethyl-Β-D-Glucuronide On Mycobacterium Tuberculosis Stimulated Lung Macrophages, Charles Inaku

Biotechnology Theses

Chronic alcohol abuse has been shown to alter immune defense mechanisms in humans and mice which makes the host susceptible to infections, including Mycobacterium tuberculosis (Mtb) infection. However, limited information is available on the mechanisms involved in alcohol-mediated host immune system dysfunction.

In this study, we determined the effects of ethyl-β-d-glucuronide (EtG), an alcohol-derived metabolite, on immune response of mice lung macrophages. We measured cytokine and chemokine production by gamma-irradiated mtb (γ-mtb) stimulated mice lung macrophages in the presence or absence of EtG. We also determined the effect of EtG on the metabolic state of γ-mtb stimulated mice lung macrophages. …

Micro-Rna Analysis Of Extracellular Vesicles Secreted By Alveolar Macrophages And Epithelial Cells In Response To Cadmium, Anisha Bhakta

Biotechnology Theses

Inhalation of cadmium (Cd) has been an environmental health concern with the increase in industrial activities and smoking. Cd exposure is known to affect several organs such as lungs, kidneys, and liver. In this study, we wanted to understand if Cd inhalation exposure can affect the lungs and other organs in the body. Exosomes are extracellular vesicles secreted by all living cells and are known to carry toxicants between organs. We investigated whether Cd exposure could affect exosome biogenesis and their composition. Cd exposure did not affect the viability of A549, a lung epithelial cell line and macrophages derived from …
