Deciphering human cell type enriched transcriptomes across tissue types and the functional study of the endothelial enriched protein KANK3
(Doctoral thesis; Doktorgradsavhandling, 2023-11-13)The identification of cell type-specific genes and their modification under certain conditions is essential for our understanding of the human body. Such knowledge also allows us to study the function of uncharacterised genes in the correct cell type. Single-cell RNA sequencing (scRNAseq) can be used to profile different cell types, but cell removal and processing can introduce artifacts. In the ... -
Temperature-dependent effects of phosphodiesterase inhibitors for cardiovascular support in hypothermic patients - Effects on cellular elimination of cAMP and cGMP
(Doctoral thesis; Doktorgradsavhandling, 2023-11-10)Hypothermia-induced cardiac dysfunction (HCD), commonly seen during rewarming, is one of the feared complications of accidental hypothermia.
