Ion channel function of polycystin‐2/polycystin‐1 heteromer revealed by structure‐guided mutagenesis

open access: yesFEBS Letters, EarlyView.
Mutations in polycystin‐1 (PC1) or polycystin‐2 (PC2) cause autosomal‐dominant polycystic kidney disease (ADPKD). We generated a novel gain‐of‐function PC2/PC1 heteromeric ion channel by mutating pore‐blocking residues. Moreover, we demonstrated that PC2 will preferentially assemble with PC1 to form heteromeric complexes when PC1 is co‐expressed ...

PolySialic Acid Nanoparticles Actuate Complement-Factor-H-Mediated Inhibition of the Alternative Complement Pathway: A Safer Potential Therapy for Age-Related Macular Degeneration

open access: yesPharmaceuticals
The alternative pathway of the complement system is implicated in the etiology of age-related macular degeneration (AMD). Complement depletion with pegcetacoplan and avacincaptad pegol are FDA-approved treatments for geographic atrophy in AMD that, while

A Comparison of the Pathway Tools Software with the Reactome Software [PDF]

open access: yesarXiv, 2020
This document compares SRI's Pathway Tools (PTools) software with the Reactome software. Both software systems serve the pathway bioinformatics area, including representation and analysis of metabolic pathways and signaling pathways. The comparison covers pathway bioinformatics capabilities, but does not cover other major facets of Pathway Tools that ...

The Group Structure of Pivot and Loop Complementation on Graphs and Set Systems [PDF]

open access: yesEuropean Journal of Combinatorics, v. 32, 1353-1367, 2011, 2009
We study the interplay between principal pivot transform (pivot) and loop complementation for graphs. This is done by generalizing loop complementation (in addition to pivot) to set systems. We show that the operations together, when restricted to single vertices, form the permutation group S_3.

Activation of the alternative complement pathway by Trichomonas vaginalis [PDF]

open access: yesInfection and Immunity, 1981
The mechanism underlying the lysis of Trichomonas vaginalis by normal human or guinea pig serum was investigated. The involvement of the complement system was demonstrated by the failure of human serum deficient in C3 or C8 to mediate parasite killing and by the ablation of lytic activity observed when fresh sera were heated at 56 degrees C or treated ...

Anti-factor B autoantibody in dense deposit disease [PDF]

open access: yes, 2010
Dense deposit disease (DDD), also known as membranoproliferative glomerulonephritis type II, is a rare kidney disorder that is associated with dysregulation of the alternative pathway of complement.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Small-molecule factor D inhibitors selectively block the alternative pathway of complement in paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome

open access: yesHaematologica, 2017
Paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome are diseases of excess activation of the alternative pathway of complement that are treated with eculizumab, a humanized monoclonal antibody against the terminal complement ...

Activation of the Alternative Complement Pathway by Fonsecaea pedrosoi

open access: yesJournal of Investigative Dermatology, 1984
Human sera were examined for evidence of complement activation by Fonsecaea pedrosoi. The serum that had been incubated with F. pedrosoi showed immunoelectrophoretic C3 conversion and generation of C5a, as measured by radioimmunoassay. C3 conversion and C5a generation did not occur in serum chelated with EDTA, or in serum heated to 56 degrees C for 30 ...

Activation of the alternative complement pathway by Naegleria fowleri [PDF]

open access: yesInfection and Immunity, 1980
Naegleria fowleri amoebae were lysed by adult fresh human serum, and their multiplication was inhibited in culture medium supplemented with 10% fresh human serum. Heat inactivation (56 degrees C, 30 min) of serum abrogated these lytic and inhibitory effects.
