Classical and alternate complement factor overexpression in non-obese weight matched women with polycystic ovary syndrome does not correlate with vitamin D

Frontiers in Endocrinology, 2022
IntroductionWomen with polycystic ovary syndrome (PCOS) exhibit complement factor expression changes that may be obesity-driven rather than an intrinsic facet of PCOS; furthermore, complement changes have been associated with vitamin D deficiency, a ...

Loss of very-long O-antigen chains optimizes capsule-mediated immune evasion by Salmonella enterica serovar Typhi. [PDF]

, 2013
UnlabelledExpression of capsular polysaccharides is a variable trait often associated with more-virulent forms of a bacterial species. For example, typhoid fever is caused by the capsulated Salmonella enterica serovar Typhi, while nontyphoidal Salmonella

Current Status of Kidney Xenotransplantation in Basic Research

Organ Medicine, EarlyView.
Kidney xenotransplantation is a potential solution to the organ shortage for end‐stage kidney disease. This review systematically elaborates on the application advances of donor pig gene editing technologies, the molecular mechanisms and regulatory strategies of xenogeneic immune rejection, and the optimization approaches of immune compatibility ...

The Murine Factor H-Related Protein FHR-B Promotes Complement Activation

Frontiers in Immunology, 2017
Factor H-related (FHR) proteins consist of varying number of complement control protein domains that display various degrees of sequence identity to respective domains of the alternative pathway complement inhibitor factor H (FH). While such FHR proteins

Human factor H-related protein 2 (CFHR2) regulates complement activation. [PDF]

PLoS ONE, 2013
Mutations and deletions within the human CFHR gene cluster on chromosome 1 are associated with diseases, such as dense deposit disease, CFHR nephropathy or age-related macular degeneration. Resulting mutant CFHR proteins can affect complement regulation.

CipA mediates complement resistance of Acinetobacter baumannii by formation of a factor I-dependent quadripartite assemblage

Frontiers in Immunology, 2022
Multidrug-resistant Acinetobacter baumannii is known to be one of the leading pathogens that cause severe nosocomial infections. To overcome eradication by the innate immune system during infection, A.

Estimation of interdomain flexibility of N-terminus of factor H using residual dipolar couplings [PDF]

, 2011
Characterization of segmental flexibility is needed to understand the biological mechanisms of the very large category of functionally diverse proteins, exemplified by the regulators of complement activation, that consist of numerous compact modules or ...

Restoration by purified C3b inactivator of complement-mediated function in vivo in a patient with C3b inactivator deficiency. [PDF]

Journal of Clinical Investigation, 1975
In a patient with lifelong increased susceptibility to infection and multiple abnormalities in complement-mediated functions, the infusion of normal plasma had been seen to produce a prolonged partial correction of serum abnormalities. It was subsequently shown that the patient was genetically deficient in the C3b inactivator and that immunochemical ...

Bone Marrow Pathology in Cold Agglutinin‐Mediated Autoimmune Hemolytic Anemia: A Study of 56 Cases

European Journal of Haematology, EarlyView.
ABSTRACT Cold agglutinin disease (CAD) is a rare form of autoimmune hemolytic anemia (AIHA). CAD occurs in the context of a small clonal B‐cell lymphoproliferation restricted to blood and/or bone marrow (BM), without overt or extramedullary lymphoma. The WHO‐HAEM5 introduced a description of the CAD‐associated lymphoproliferative disorder (CAD‐LPD) in ...
