Potential mechanisms involved on how systemic IgG antibodies specific to vascular endothelial growth factor (VEGF) and induced by active immunotherapy decrease platelet derived free-VEGF

Platelets, 2022
CIGB-247 is a vascular endothelial growth factor (VEGF)-based active immunotherapy and it is currently under investigation for cancer treatment. This specific active immunotherapy encompasses two vaccine candidates that use a human VEGF variant molecule ...

Augmentation of Staphylococcal α-Toxin Signaling by the Epidermal Platelet-Activating Factor Receptor [PDF]

, 2003
Staphylococcal α-toxin is a cytolytic toxin secreted by many strains of Staphylococcus aureus that has proinflammatory and cytotoxic effects on human keratinocytes. α-toxin exerts its effects by forming a transmembrane pore that behaves like an ionophore

RGS4 inhibits platelet-activating factor receptor phosphorylation and cellular responses

, 2001
To define the role of regulators of G-protein signaling (RGS) in chemoattractant-mediated responses, RGS4 and the receptors for platelet-activating factor (PAFR), formylated peptides (FR), or interleukin-8 (CXCR1) were stably coexpressed in a rat ...

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Lipooligosaccharide Ligands from Respiratory Bacterial Pathogens Enhance Cellular Uptake of Nanoparticles

KONA Powder and Particle Journal, 2023
Several bacterial pathogens contain membrane ligands that facilitate their binding and internalization into human tissues. In this study, lipooligosaccharides (LOS) from the respiratory pathogen non-typeable Haemophilus influenzae (NTHi) were isolated ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
