Recurrent pyogenic infections caused by a novel Gln1420* mutation in the C3 gene

open access: yesFrontiers in Pediatrics, 2022
C3 is a crucial protein of the complement system. Congenital C3 deficiency is extremely rare and manifests through recurrent, severe infections and should always be considered as a differential diagnosis of recurrent pyogenic infections. We report a case

Complement and Chlamydia psittaci: Early Complement-Dependent Events Are Important for DC Migration and Protection During Mouse Lung Infection

open access: yesFrontiers in Immunology, 2021
The zoonotic intracellular bacterium Chlamydia psittaci causes life-threatening pneumonia in humans. During mouse lung infection, complement factor C3 and the anaphylatoxin C3a augment protection against C. psittaci by a so far unknown mechanism.

Assessment of the Role of C3(H2O) in the Alternative Pathway

open access: yesFrontiers in Immunology, 2020
In this study we investigate the hydrolysis of C3 to C3(H2O) and its ability to initiate activation via the alternative pathway (AP) of the complement system.

Conformational Complexity of Complement Component C3

open access: yes, 2007
The structures of native C3 and its major fragment C3c have provided a wealth of structural insights into the central protein of the complement system. The proteolytic activation steps, generating the important fragments C3b and iC3b, are thought to induce significant conformational changes in the molecule, yielding protein molecules with distinct ...
