Expression Of Complement And Toll-Like Receptor Pathway Genes Is Associated With Malaria Severity In Mali: A Pilot Case Control Study, Rafal S. Sobota, Antoine Dara, Jessica E. Manning, Amadou Niangaly

Dartmouth Scholarship

Background: The host response to infection by Plasmodium falciparum, the parasite most often responsible for severe malaria, ranges from asymptomatic parasitaemia to death. The clinical trajectory of malaria is influenced by host genetics and parasite load, but the factors determining why some infections produce uncomplicated malaria and some proceed to severe disease remain incompletely understood.

Methods: To identify molecular markers of severe falciparum malaria, human gene expression patterns were compared between children aged 6 months to 5 years with severe and uncomplicated malaria who were enrolled in a case–control study in Bandiagara, Mali. Microarrays were used to obtain expression …

Molecular Genetics Of Ms4a6a And Alzheimer's Disease, Ryan Harpole

Lewis Honors College Capstone Collection

Increased Alzheimer’s disease (AD) risk has previously been associated with a SNP called rs610932 near the gene MS4A6A. The goal of this experiment was to quantify the expression of two MS4A6A isoforms in the brains of AD and non-AD subjects, particularly as a function of rs610932 genotype. According to an article titled “Alzheimer’s Disease Susceptibility Variants in the MS4A6A Gene are Associated with Altered Levels of MS4A6A Expression in Blood”, MS4A6A has four different isoforms that have been reported to be differentially expressed in the blood of AD subjects compared to non-AD subjects (Petroula et al., 2014). After statistically …
