26. Multiple functions of YopN in the Yersinia pseudotuberculosis type III secretion system : from regulation to in vivo infection
Sammanfattning : The type 3 secretion systems (T3SSs) are virulence mechanisms used by various Gram-negative bacteria to overcome the host immunity. They are often target-cell contact induced and activated. Activation results in targeting of virulence effector substrates into host cells. LÄS MER
27. Interactions between Streptococcus pyogenes and the Human Immune System
Sammanfattning : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. LÄS MER
28. Commensal microbes, immune reactivity and childhood inflammatory bowel disease
Sammanfattning : Inflammatory bowel disease (IBD) is characterized by chronic and relapsing intestinal inflammation of unknown etiology, but immune activation by the commensal microbiota probably plays a major role. The two major categories of IBD are ulcerative colitis and Crohn’s disease. LÄS MER
29. Immunity & the butterfly : A functional genomic study of natural variation in immunity
Sammanfattning : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. LÄS MER
30. Functional characterization of pro-angiogenic neutrophils
Sammanfattning : The vascular system stretches throughout the body to provide oxygen, nutrition, and to remove waste products from cell metabolism. Angiogenesis, formation of new blood vessels by sprouting from pre-existing vessels, is one of the main mechanisms involved in blood vessel formation. LÄS MER
