1. Antigenic variation in relapsing fever Borrelia
Sammanfattning : The spirochete Borrelia hermsii avoids the immune response of its mammalian host through multiphasic antigenic variation. Serotype specificity is determined by Variable major proteins (Vmp), in the outer membrane. LÄS MER
2. Streptococcal M protein and human C4BP
Sammanfattning : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. LÄS MER
3. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes
Sammanfattning : Many microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. LÄS MER
4. Antigenic variation in Plasmodium falciparum : understanding the RIFIN protein family
Sammanfattning : RIFIN proteins are variable surface antigens, which have a central role in the survival and virulence of the malaria parasite Plasmodium falciparum. Antigenic variation is a mean for these parasites to avoid clearance by the host s immune system. However, this is often a secondary function to the main role of these proteins. LÄS MER
5. Comparative Cell Biology in Diplomonads
Sammanfattning : The diplomonads are a diverse group of eukaryotic flagellates found in microaerophilic and anaerobic environments. The most studied diplomonad is the intestinal parasite Giardia intestinalis, which infects a variety of mammals and cause diarrheal disease. LÄS MER
