2. 6. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

   Author : Eskil Johnsson; Institutionen för laboratoriemedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

   Abstract : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. READ MORE

4. 7. Novel endogenous mechanisms of complement regulation - A delicate balance

   Author : Andreas Holmér; Malmö Klinisk kemi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; short leucine rich glycoprotein; factor H; C1q; age-related macular degeneration; C4b-binding protein; prion disease; prion protein; Complement regulation; C-reactive protein;

   Abstract : In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. READ MORE

5. 8. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes

   Author : Karin Berggård; Lund Dermatologi och venereologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; antigenic variation; phagocytosis resistance; complement; C4b-binding protein C4BP ; Bordetella pertussis; Streptococcus pyogenes; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : 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. READ MORE

6. 9. Innate immunity in diabetes mellitus. Complement components C4BP and C3 promote survival of β cells under metabolic challenges

   Author : Klaudia Kulak; Malmö Proteinkemi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement System; Inflammasome; Islet Amyloid Polypeptide; Complement C3; C4b-binding protein C4BP ; Interleukin 1β; Autophagy-Related Protein 16 like 1; Diabetes mellitus; type 2;

   Abstract : The Complement system is a main effector mechanism of the innate immune system, acting to enhance clearance of pathogens, but also aids removal of biological debris from the body, including immunocomplexes, apoptotic/necrotic cells and protein aggregates. Complement regulators serve to prevent excessive inflammation and their interaction with the same materials targeted by the complement system results in ‘silent’ cleaning of wastes. READ MORE

7. 10. Interaction of Triglyceride-rich Lipoproteins with Platelets and Vitamin K-dependent Coagulation Factors

   Author : Ning Xu; Avdelningen för klinisk kemi och farmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triglycerides.; Prothrombin; Protein S; Protein C; Platelets; Phospholipids; Metabolism; Lipoproteins; Lipids; Endocytosis; Electron microscopy; Cytochemistry; Coronary heart disease; Blood coagulation factors; Arachidonic acid; Atherosclerosis; Clinical chemistry; Klinisk kemi; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

   Abstract : 1. During incubation of platelets with 3H-arachidonic acid (20:4, n-6) and 14C-cholesterol doubly labelled and colloidal gold labelled chylomicrons (CMs) and chylomicron remnants (CMRs) CMs were taken up more efficiently than CMRs. Addition of unlabelled CMs, VLDLs, LDLs and HDLs decreased the uptake of labelled CMs. READ MORE
