Tribochemistry as an Alternative Synthesis Pathway [PDF]

open access: yesLubricants, 2020
While reactions driven by mechanical force or stress can be labeled mechanochemical, those specifically occurring at a sliding interface inherit the name tribochemical, which stems from the study of friction and wear: tribology. Increased perception of tribochemical reactions has been gained through technological advancement, and the development of new

An alternative cytokinin biosynthesis pathway [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
Studies of de novo cytokinin biosynthesis in isopentenyltransferase ( ipt )-transformed Arabidopsis thaliana , involving in vivo deuterium labeling and mass spectrometry, showed that the biosynthetic rate of zeatinriboside-5′-monophosphate was

Soluble collectin-12 mediates C3-independent docking of properdin that activates the alternative pathway of complement

open access: yeseLife, 2020
Properdin stabilizes the alternative C3 convertase (C3bBb), whereas its role as pattern-recognition molecule mediating complement activation is disputed for decades.

Multiple Pathways in NaCl Homogeneous Crystal Nucleation [PDF]

open access: yes, 2021
NaCl crystal nucleation from metastable solutions has long been considered to occur according to a single-step mechanism. Recent experimental observations suggest that NaCl crystals emerge from disordered intermediates which is seemingly at odds with this established view. Here, we performed biased and unbiased molecular dynamics simulations to analyse

Properdin inhibition ameliorates hepatic ischemia/reperfusion injury without interfering with liver regeneration in mice

open access: yesFrontiers in Immunology, 2023
Hepatic ischemia/reperfusion injury (IRI) often causes serious complications in liver surgeries, including transplantation. Complement activation seems to be involved in hepatic IRI; however, no complement-targeted intervention has been clinically ...

Unbinding of Retinoic Acid from its Receptor Studied by Steered Molecular Dynamics [PDF]

open access: yesBiophysical Journal 76, 188 (1999), 1999
Retinoic acid receptor (RAR) is a ligand-dependent transcription factor that regulates the expression of genes involved in cell growth, differentiation, and development. Binding of the retinoic acid hormone to RAR is accompanied by conformational changes in the protein which induce transactivation or transrepression of the target genes.

The dual nature of TDC – bridging dendritic and T cells in immunity

open access: yesFEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

In vaccinated individuals serum bactericidal activity against B meningococci is abrogated by C5 inhibition but not by inhibition of the alternative complement pathway

open access: yesFrontiers in Immunology, 2023
IntroductionSeveral diseases caused by the dysregulation of complement activation can be treated with inhibitors of the complement components C5 and/or C3.

Alternate pathways of cerebroside catabolism [PDF]

open access: yesLipids, 1973
AbstractA search was made for new degradative pathways for glucosyl and galactosyl ceramides in an effort to explain the failure of these lipids to accumulate in the brains of children with Krabbe's or Gaucher's disease. Using various buffers and incubation conditions, we tested brain homogenates from 12 day old rats with the stearate‐labeled and ...

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

open access: yesFEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
