Schistosomiasis is a Neglected Tropical Disease caused by a parasitic blood fluke. There are currently over 240 million people affected globally. Humans become infected after coming into contact with water containing the infectious stage of the parasite. Our data consists of egg counts for Schistosoma haematobium and Schistosoma mansoni collected from school-aged children in Tomefa, Ghana, a marginalized informal community, between 2014 and 2019. Our research explores whether or not reinfections and continuous infections were occurring over the six-year period. Although the government conducts periodic mass drug administration, reinfections are likely given the social and environmental conditions in the community. …

Xenopus laevis, is an excellent model organism for transgenesis and immunological research due to their large eggs and the similarities between mammalian and amphibian immune systems. MHC Class I is found on nearly all cells and educates T cells to recognize between self and non-self which is an essential immune system function. However, tadpoles don’t have detectable MHC Class I expression while adult frogs do. Despite this tadpoles are still immunocompetent; thus the role of MHC Class I in tadpoles is unknown. To investigate MHC Class I function we inactivated the corresponding gene in Xenopus laevis using CRISPR/Cas9. The …

465— Modeling Vaccine Efficacy For Tuberculosis In A Prison Population, Kaitlyn Mundackal

Tuberculosis is a highly contagious disease and is particularly problematic in confined communities such as prisons. I simulated how Tuberculosis moves through a prison population and tested how much vaccination effort is needed to control its spread. To explore this, I tested adding ever increasing numbers of randomly placed edges in a network and determined the size of the largest component. Afterwards, I removed edges in the model using two different methods, one illustrating if the edges were removed randomly and the other starting with prisoners that had the most connections, to simulate the effect of vaccination. My results show …

Increased expression of human leukocyte antigen (HLA) allows tumor cells to be more easily detected by the immune system. In previous research, epigenetic modifiers including the histone deacetylase inhibitor 3 (HDAC3), RGFP966, has been shown to decrease PD-L1 expression. PD-L1 expression inhibits T cell cytotoxicity, and decreasing it can enhance the immune response. We hope to elucidate whether or not HLA-ABC expression similarly decreases upon exposure to the HDAC3 inhibitor which would be detrimental to immune detection. Two breast cancer cell lines that express HLA-ABC are MCF-7 and MDA-MB-231. Our initial results show that HLA-ABC is expressed on the MDA-MB-231 …
