Human complement regulators C4b-binding protein and C1 esterase inhibitor interact with a novel outer surface protein of Borrelia recurrentis. [PDF]

PLoS Neglected Tropical Diseases, 2010
The spirochete Borrelia recurrentis is the causal agent of louse-borne relapsing fever and is transmitted to humans by the infected body louse Pediculus humanus. We have recently demonstrated that the B.

SARS-CoV-2 Spike- and Nucleoprotein-Specific Antibodies Induced After Vaccination or Infection Promote Classical Complement Activation

Frontiers in Immunology, 2022
Antibodies specific for the spike glycoprotein (S) and nucleocapsid (N) SARS-CoV-2 proteins are typically present during severe COVID-19, and induced to S after vaccination.

Defining Targets for Complement Components C4b and C3b on the Pathogenic Neisseriae [PDF]

Infection and Immunity, 2008
ABSTRACTComplement is a key arm of the innate immune defenses against the pathogenic neisseriae. We previously identified lipooligosaccharide onNeisseria meningitidisas an acceptor for complement C4b. Little is known about other neisserial targets for complement proteins C3 and C4, which covalently attach to bacterial surfaces and initiate opsonization

Complement activation and protein adsorption by carbon nanotubes [PDF]

, 2006
As a first step to validate the use of carbon nanotubes as novel vaccine or drug delivery devices, their interaction with a part of the human immune system, complement, has been explored.

Complement System Part I – Molecular Mechanisms of Activation and Regulation [PDF]

, 2015
Complement is a complex innate immune surveillance system, playing a key role in defense against pathogens and in host homeostasis. The complement system is initiated by conformational changes in recognition molecular complexes upon sensing danger ...

The effects of tidal volume size and driving pressure levels on pulmonary complement activation: an observational study in critically ill patients

Intensive Care Medicine Experimental, 2020
Background Mechanical ventilation can induce or even worsen lung injury, at least in part via overdistension caused by too large volumes or too high pressures.
