Project description:The goals of this study were to determine differential gene expression between Achromobacter xylosoxidans clinical isolate Ax 7 in a synthetic artificial sputum media compared to a rich media control (LB).
Project description:Porcine alveolar macrophages (PAMs) play an important role in innate immunity. Streptococcus suis serotype 2 is a pathogen responsible for several diseases in both pigs and humans. We used microarrays to study the transcriptome of PAMs infected with SS2.
Project description:The outbreak-causing monkeypox virus of 2022 (2022 MPXV) is classified as a clade IIb strain and phylogenetically distinct from prior endemic MPXV strains (clades I or IIa), suggesting that its virological properties may also differ. Here, we used human keratinocytes and induced pluripotent stem cell-derived colon organoids to examine the efficiency of viral growth in these cells and the MPXV infection-mediated host responses. MPXV replication was much more productive in keratinocytes than in colon organoids. We observed that MPXV infections, regardless of strain, caused cellular dysfunction and mitochondrial damage in keratinocytes. Notably, a significant increase in the expression of hypoxia-related genes was observed specifically in 2022 MPXV-infected keratinocytes. Our comparison of virological features between 2022 MPXV and prior endemic MPXV strains revealed signaling pathways potentially involved with the cellular damages caused by MPXV infections and highlights host vulnerabilities that could be utilized as protective therapeutic strategies against human mpox in the future.
