Project description:Generation of single cell and single nuclei transcriptomic data of post-mortem tissues from a Malawi cohort. We aim to explore differences in the immune response between Covid-19, Non-Covid19 LRTD (lower respiratory tract disease) and no-LTRD at the single cell level from lung, nasal and blood. Autopsies were conducted through minimally invasive autopsy using needle-biopsy. Samples were then processed with a 10X Chromium in Blantyre, Malawi. Some samples were run individually and others pooled. Pooled samples were split using single nucleotide polymorphisms or through hashtag oligonucelotides. Data processing and analysis was performed in R using the Seurat package.

Project description:Transcriptome profiling of pyrethroid resistant field populations of Anopheles funestus from Malawi and Mozambique compared to a susceptible lab strain FANG
Project description:Transcription profiling of permethrin resistant field mosquito samples of Anopheles funestus from three Southern African populations (Mozambique, Malawi and Zambia) compared to a susceptible lab strain FANG
Project description:<p>Esophageal squamous cell carcinoma (ESCC) occurs as much as 20x more frequently in sub-Saharan Africa than Western countries. Through the UNC-Malawi project collaboration we obtained whole-exome matched tumor/normal and RNA sequencing of 59 ESCC from Malawi between 2011-2012. DNA analysis revealed similar mutations as other cohorts, while RNA analysis revealed three distinct subtypes. Mutational signature analysis revealed a pattern of mutation not previously reported in other cohorts or more broadly. Taken together this suggests the high prevalence of ESCC in the region is secondary to an as yet identified mutagen. </p>
Project description:We use the continuously replacing dentition of Lake Malawi cichlid fishes to understand de-novo tooth replacement in adult vertebrates. In this system, each tooth is replaced in a one-for-one fashion every ~50 days. Here, we explore the source of epithelial stem cells for tooth replacement.
