Social Interactions And Spatial Structure Drive Community Assembly Of Bacterial Biofilm, Matthew C. Bond
Social Interactions And Spatial Structure Drive Community Assembly Of Bacterial Biofilm, Matthew C. Bond
Dartmouth College Ph.D Dissertations
Despite the critical nature which microbial communities play in the natural world and human civilization, the breadth of understanding remains shallow. Challenged by scale, high variability between environments, and extensive diversity, microbial ecologists strive to understand connections between a community’s structure and function, as well as the ecological and evolutionary mechanisms underlying observed natural patterning of communities. Biofilms are the predominate mode of growth for microbial communities—characterized by cellular attachment to a surface via a self-produced matrix and heterogeneous structure, often resulting in a primary growth front along the biofilm surface due to differential access to bulk nutrients (cite). This …

The Immune Modulation On Innate Immunity, From Pathogen Recognition To Fungal Clearance., Ko-Wei Liu

The human lung is not sterile but a complex environment with various microorganisms. Besides commensals in the lung, hundreds to thousands of individual microbiomes enter the lung every day but without causing the symptom. Host innate immunity plays an important role in maintaining homeostasis of the lung environment and as the first defense line against pathogens. Aspergillus fumigatus (A. fumigatus) is a saprophytic filamentous fungus that can cause human disease in immune compromised patients. However, with functional innate immunity, immune cells can quickly recognize pathogen associated molecular patterns (PAMPs) from A. fumigatus through pattern recognition receptors (PRRs). The activation of …

Response And Molecular Control Of Cd8 T Cells During Infection And Cancer, Nicholas K. Preiss Dr.
Dartmouth College Ph.D Dissertations
CD8 T cells are potent immune effector cells capable of vast clonal expansion and clearance of infected or cancerous cells. After control of the pathogenic insult, CD8 T cells develop into quiescent, long-lived memory populations that are poised to mediate rapid protection upon reencounter with cognate antigen. These properties make control of CD8 T cell responses a highly desirable outcome of vaccine strategies and immunotherapy. Therefore, understanding how the effector function and memory differentiation of CD8 T cells are controlled at a molecular level is of great importance. In the context of infection with gammaherpesviruses (γHV), which form a latent …
