Electrostatic Steering Accelerates C3d:CR2 Association. [PDF]

open access: yes, 2016
Electrostatic effects are ubiquitous in protein interactions and are found to be pervasive in the complement system as well. The interaction between complement fragment C3d and complement receptor 2 (CR2) has evolved to become a link between innate and ...

Alternative Pathway of Complement in Sickle Cell Disease [PDF]

open access: yesPediatric Research, 1977
Thirty-one patients, 10 months to 20 years of age, were studied. A complement abnormality was not identified in sera from patients with sickle cell disease (SCD) by the methods employed in the present study. Concentrations of C3, factor B, total hemolytic activity (CH50), properdin, and C3b inactivator were similar in sera from patients and control ...

Germline mutations in the alternative pathway of complement predispose to HELLP syndrome.

open access: yesJCI Insight, 2018
BACKGROUND HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome is a severe variant of hypertensive disorders of pregnancy affecting approximately 1% of all pregnancies, and has significant maternal and fetal morbidity.

Novel and unscrutinized immune entities of the zebrafish gut

open access: yesFEBS Letters, EarlyView.
Understudied cells of the zebrafish immune system include bona fide immune cells and epithelial (‐derived) cells with immune functions. Research focusing on zebrafish cells which demonstrate similarities to mammalian immune cell counterparts may help us understand the pathologies in which they are implicated. Currently available and advanced tools make

Complement C3 variant and the risk of age-related macular degeneration [PDF]

open access: yes, 2007
Background: Age-related macular degeneration is the most common cause of blindness in Western populations. Susceptibility is influenced by age and by genetic and environmental factors.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

A C3(H20) recycling pathway is a component of the intracellular complement system [PDF]

open access: yes, 2017
An intracellular complement system (ICS) has recently been described in immune and nonimmune human cells. This system can be activated in a convertase-independent manner from intracellular stores of the complement component C3. The source of these stores

Ischemia and reperfusion injury in kidney transplantation : relevant mechanisms in injury and repair [PDF]

open access: yes, 2020
Ischemia and reperfusion injury (IRI) is a complex pathophysiological phenomenon, inevitable in kidney transplantation and one of the most important mechanisms for non- or delayed function immediately after transplantation.

Methylprednisolone inhibits the alternative and amplification pathways of complement [PDF]

open access: yesInfection and Immunity, 1982
Methylprednisolone sodium succinate limited the ability of zymosan or lipopolysaccharide to activate complement in normal serum by the alternative amplification pathways. Methylprednisolone limited B consumption in a reaction mixture which contained purified C3b, D, and B, indicating that soluble steroid directly inhibited the amplification pathway ...
