11. Epidemiological and Bacteriological Aspects of Spotted Fever Rickettsioses in Humans, Vectors and Mammals in Sweden
Sammanfattning : Rickettsiae are obligate intracellular gram-negative bacteria transmitted by arthropod vectors. Rickettsiae sometimes cause disease in humans, typically with high fever, headache and occasionally an eschar.In Sweden, Rickettsia helvetica, belonging to the spotted fever group, is the only tick-transmitted rickettsia found free in nature.

12. Genetic content of clinical pneumococcal isolates and its relation to disease outcome
Sammanfattning : Streptococcus pneumoniae is a Gram-positive bacterium that can cause a wide range of diseases. These include otitis media, sinusitis, pneumonia and meningitis. It can, however, also cause asymptomatic carriage thereby behaving almost like a commensal. LÄS MER
13. Regulation of cell polarity and invasion by TGF-β and BMP signaling
Sammanfattning : Transforming growth factor β (TGF-β) and bone morphogenetic protein (BMP) signaling pathways are involved in many physiological processes during embryonic and adult life. TGF-β promotes epithelial to mesenchymal transition (EMT). We identified a gene target of TGF-β signaling, encoding the salt-inducible kinase 1 (SIK1). LÄS MER
14. Akt signaling and coordinated changes in the distribution and expression of Akt-regulating phosphatases
Sammanfattning : Cancer is one of the major causes of death worldwide. The PI3K/Akt signaling pathway is up-regulated in a variety of human cancers. Akt is an important signaling molecule in cellular survival pathways. Activated Akt (pAkt) is able to induce protein synthesis pathways, and is therefore a key protein involved in growth and prevention of apoptosis. LÄS MER
15. Molecular factors influencing epithelial-mesenchymal transition in breast cancer
Sammanfattning : Epithelial-mesenchymal transition (EMT) is a developmental process defined by loss of epithelial characteristics and acquisition of mesenchymal phenotype. EMT or similar processes are also implicated in carcinoma cell invasion and the progression of breast carcinoma to metastasis. LÄS MER
