A case of remittent C1-inhibitor deficiency

, 2015
C1-inhibitor is a serine protease inhibitor (serpin) controlling complement and kinin/contactsystem activation. Mutations in C1-inhibitor gene almost consistently result in reduced C1-inhibitor functional level in plasma causing hereditary angioedema, a ...

Complement C1-inhibitor expression in Alzheimer's disease

, 1998
In situ and in vitro studies suggest that activation of locally produced complement factors may act as a mediator between amyloid deposits and neurodegenerative changes seen in Alzheimer's disease (AD).

Modification‐Selective Inhibition of Succinate Dehydrogenase a Enables Tumor‐Restricted Mitochondrial Modulation

Advanced Science, EarlyView.
This work identifies acetylation‐dependent SDHA homeostasis as a determinant of tumor‐specific metabolic vulnerability. Guided by this mechanism, a modification‐selective inhibitor, ZPI‐3, selectively targets non‐acetylated SDHA, achieving tumor‐restricted SDH inhibition and effective bladder cancer control. Differential responses in clinical specimens

Proteomic results indicate inhibition of complement cascades is one of the mechanisms underlying the protective effects of Tongxinluo against myocardial infarction

Frontiers in Pharmacology
ObjectiveTongxinluo (TXL), a traditional Chinese medicine, has demonstrated cardioprotective effects in acute myocardial infarction (AMI), yet its impact on myocardial protein profiles remains largely unexplored.

Conserved Surface-Exposed K/R-X-K/R Motifs and Net Positive Charge on Poxvirus Complement Control Proteins Serve as Putative Heparin Binding Sites and Contribute to Inhibition of Molecular Interactions with Human Endothelial Cells: a Novel Mechanism for Evasion of Host Defense [PDF]

, 2000
Vaccinia virus complement control protein (VCP) has been shown to possess the ability to inhibit both classical and alternative complement pathway activation.

Properdin and factor H: Opposing players on the alternative complement pathway "see-saw" [PDF]

, 2013
This article has been made available through the Brunel Open Access Publishing Fund.Properdin and factor H are two key regulatory proteins having opposite functions in the alternative complement pathway.

F‐Type Pyocin Versus Phage λ Tail: Conserved Hub, Divergent Fibers

Advanced Science, EarlyView.
Near‐atomic cryo‐EM structures of a Gram‐negative F‐type pyocin reveal a conserved tail tip architecture shared with bacteriophage λ together with a previously unrecognized side‐fiber attachment mode. These findings provide new insight into tailocin assembly and host recognition and establish a structural framework for engineering precision ...

Anti-GD1a antibodies activate complement and calpain to injure distal motor nodes of Ranvier in mice [PDF]

, 2010
The motor axonal variant of Guillain-Barré syndrome is associated with anti-GD1a immunoglobulin antibodies, which are believed to be the pathogenic factor. In previous studies we have demonstrated the motor terminal to be a vulnerable site.

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Complement Activation During Ischemia/Reperfusion Injury Induces Pericyte-to-Myofibroblast Transdifferentiation Regulating Peritubular Capillary Lumen Reduction Through pERK Signaling

Frontiers in Immunology, 2018
Pericytes are one of the principal sources of scar-forming myofibroblasts in chronic kidneys disease. However, the modulation of pericyte-to-myofibroblast transdifferentiation (PMT) in the early phases of acute kidney injury is poorly understood.
