1. 31. Regulation of B cell motility and adhesion in health and disease

   Författare :Lisa Westerberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :B cells; Migration; Adhesion; WASP; immune deficiency;

   Sammanfattning : Migration and adhesion of lymphocytes are crucial to induce an efficient immune response. These activities rely on cytoskeletal dynamics, mediated by assembly of actin and microtubuli monomers leading to changes in cell shape and signaling. LÄS MER

3. 32. Bacterial interaction with the fibrinolytic system and extracellular matrix

   Författare :Thomas Herrman Eberhard; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :plasminogen; extracellular matrix; basement membrane; virulence factors; fibronectin; vitronectin; collagen; Haemophilus influenzae Neisseria meningitidis Streptococcus pneumoniae;

   Sammanfattning : Bacterial infection of host organisms is a state of complex interaction between the parasite and the host. Two critical steps in the infectious process are: Adhesion to the epithelial surfaces and penetration of tissue barriers to gain entrance to tissues and into the circulation. These two steps have been the subjects of this thesis. LÄS MER

4. 33. Regulation of internalization and replication of intracellular bacterial pathogens

   Författare :Eugénie Bassères; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The capacity of intracellular bacteria to cause disease depends on their ability to invade and replicate within eukaryotic host cells. These characteristics also allow preferential invasion and replication by facultative anaerobic bacteria in solid tumours, which can be exploited to design delivery vectors for cancer therapy.

5. 34. Cell adhesion molecules during odontogenesis and tooth-related diseases

   Författare :Robert Heymann; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cell adhesion molecules play essential roles in the development and disease of tooth and oral structures, as well as in the maintenance of adult tissue structure/function. It has been shown that different types of cell adhesion molecules (CAMs) play an important part in craniofacial development when ectomesenchymal cells migrate from the neural list to the primitive oral cavity, giving rise to the palatal processes and tooth germs.

7. 35. Host responses and bacterial virulence factors in Neisseria infections

   Författare :Linda Johansson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Neisseria; CD46; LPS; antimicrobial peptide.;

   Sammanfattning : Neisseria meningitidis and Neisseria gonorrhoeae are human specific pathogens. N. meningitidis is a major cause of meningitis and sepsis, whilst N. gonorrhoeae causes many millions of cases of gonorrhea in the world every year. LÄS MER
