1. Stability of bacterial DNA in relation to microbial detection in teeth
Sammanfattning : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. LÄS MER
2. The release of histone proteins from cells via extracellular vesicles
Sammanfattning : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. LÄS MER
3. Inflammatogenic properties of endogenous DNA
Sammanfattning : Bacterial DNA and CpG-containing oligodeoxynucleotides (ODNs) induce host inflammatory responses as a result of their content of unmethylated ¡§CpG motifs¡¨. Since the CpG motifs in the mitochondrial (mt) genome are in this respect similar to bacterial DNA, in that they are non-methylated, we investigated whether mtDNA also displays inflammatogenic potential.

4. The Impact of Tryptase and Epigenetic Mechanisms on Mast Cells
Sammanfattning : Mast cells have a large influence on multiple immune-mediated responses, including allergic conditions, and they have been implicated in various diseases such as arthritis and cancer. Mastocytosis is characterized by abnormal mast cell proliferation induced by mutations in KIT, the stem cell factor (SCF) receptor. LÄS MER
5. Imaging and Spectroscopic Mapping of Blood Cell Activity : Nanoparticles and Neutrophil Extracellular Traps
Sammanfattning : Imaging and visualization of cell activity when exposed to nanomaterial are of main importance, when investigating biological response to a wide range of biomaterials from medical implants to smart nanoprobes. The ability to provide molecular and chemical information with spatial resolution in the region of sub-µm leads to increased insight and understanding of these biological challenges. LÄS MER
