Clinical and translational medicine

Lopez-Sanz L, Bernal S, Jimenez-Castilla L, Prieto I, La Manna S, Gomez-Lopez S, Blanco-Colio LM, Egido J, Martin-Ventura JL, Gomez-Guerrero C.
PMID: 34323424
Clin Transl Med. 2021 Jul;11(7):e463. doi: 10.1002/ctm2.463.

BACKGROUND: Abdominal aortic aneurysm (AAA), a degenerative vascular pathology characterized by permanent dilation of the aorta, is considered a chronic inflammatory disease involving innate/adaptive immunity. However, the functional role of antibody-dependent immune response against antigens present in the damaged...

Drug metabolism and disposition: the biological fate of chemicals

Pike A, Jones B, Markandu R, O'Neill D.
PMID: 34135088
Drug Metab Dispos. 2021 Sep;49(9):736-742. doi: 10.1124/dmd.121.000409. Epub 2021 Jun 16.

Inconsistencies in pharmacokinetic parameters between individual animals in preclinical studies are a common occurrence. Often such differences between animals are simply accepted as experimental variability rather than as indications of specific differences in animal phenotype that could lead to...

Temporal Roles of Platelet and Coagulation Pathways in Collagen- and Tissue Factor-Induced Thrombus Formation.

International journal of molecular sciences

Navarro S, Stegner D, Nieswandt B, Heemskerk JWM, Kuijpers MJE.
PMID: 35008781
Int J Mol Sci. 2021 Dec 29;23(1). doi: 10.3390/ijms23010358.

In hemostasis and thrombosis, the complex process of thrombus formation involves different molecular pathways of platelet and coagulation activation. These pathways are considered as operating together at the same time, but this has not been investigated. The objective of...

Naturally occurring anti-band 3 antibodies in clearance of senescent and oxidatively stressed human red blood cells.

Transfusion medicine and hemotherapy : offizielles Organ der Deutschen Gesellschaft fur Transfusionsmedizin und Immunhamatologie

Lutz HU.

Transfus Med Hemother. 2012 Oct;39(5):321-7. doi: 10.1159/000342171. Epub 2012 Aug 27.

SUMMARY: Naturally occurring anti-band 3 antibodies (anti-band 3 NAbs) are directed against the 55-kDa chymotryptic fragment of the anion transport protein (band 3) of red blood cells (RBCs). They bind to senescent and oxidatively stressed RBCs and induce their...

Britanin Suppresses IgE/Ag-Induced Mast Cell Activation by Inhibiting the Syk Pathway.

Biomolecules & therapeutics

Lu Y, Li X, Park YN, Kwon O, Piao D, Chang YC, Kim CH, Lee E, Son JK, Chang HW.
PMID: 25009699
Biomol Ther (Seoul). 2014 May;22(3):193-9. doi: 10.4062/biomolther.2014.038.

The aim of this study was to determine whether britanin, isolated from the flowers of Inula japonica (Inulae Flos), modulates the generation of allergic inflammatory mediators in activated mast cells. To understand the biological activity of britanin, the authors...

FcγRIIIB stimulation promotes β1 integrin activation in human neutrophils.

Journal of leukocyte biology

Ortiz-Stern A, Rosales C.
PMID: 29350792
J Leukoc Biol. 2005 May;77(5):787-799. doi: 10.1189/jlb.0504310.

The molecular stimuli involved in receptor-induced integrin activation are still poorly defined. We have investigated the role of receptors for the Fc portion of immunoglobulin G molecules (FcγR) on activation of integrins in human neutrophils. Cross-linking of FcγRIIA induced...

Acquired platelet GPVI receptor dysfunction in critically ill patients with sepsis.

Blood

Weiss LJ, Manukjan G, Pflug A, Winter N, Weigel M, Nagler N, Kredel M, Lâm TT, Nieswandt B, Weismann D, Schulze H.
PMID: 33827131
Blood. 2021 Jun 03;137(22):3105-3115. doi: 10.1182/blood.2020009774.

Glycoprotein VI (GPVI), the platelet immunoreceptor tyrosine activating motif (ITAM) receptor for collagen, plays a striking role on vascular integrity in animal models of inflammation and sepsis. Understanding ITAM-receptor signaling defects in humans suffering from sepsis may improve our...

Obinutuzumab-mediated high-affinity ligation of FcγRIIIA/CD16 primes NK cells for IFNγ production.

Oncoimmunology

Capuano C, Pighi C, Molfetta R, Paolini R, Battella S, Palmieri G, Giannini G, Belardinilli F, Santoni A, Galandrini R.
PMID: 28405525
Oncoimmunology. 2017 Feb 10;6(3):e1290037. doi: 10.1080/2162402X.2017.1290037. eCollection 2017.

Natural killer (NK) cell-mediated antibody-dependent cellular cytotoxicity (ADCC), based on the recognition of IgG-opsonized targets by the low-affinity receptor for IgG FcγRIIIA/CD16, represents one of the main mechanisms by which therapeutic antibodies (mAbs) mediate their antitumor effects. Besides ADCC,...

The monocyte Fcγ receptors FcγRI/γ and FcγRIIA differ in their interaction with Syk and with Src-related tyrosine kinases.

Journal of leukocyte biology

Huang ZY, Hunter S, Kim MK, Chien P, Worth RG, Indik ZK, Schreiber AD.
PMID: 29350785
J Leukoc Biol. 2004 Aug;76(2):491-499. doi: 10.1189/jlb.1103562.

There are important differences in signaling between the Fc receptor for immunoglobulin G (IgG) FcγRIIA, which uses the Ig tyrosine-activating motif (ITAM) within its own cytoplasmic domain, and FcγRI, which transmits signals by means of an ITAM located within...

Inhibition of SYK kinase does not confer a pro-proliferative or pro-invasive phenotype in breast epithelium or breast cancer cells.

Oncotarget

Lamb DJ, Rust A, Rudisch A, Glüxam T, Harrer N, Machat H, Christ I, Colbatzky F, Wernitznig A, Osswald A, Sommergruber W.

Oncotarget. 2020 Apr 07;11(14):1257-1272. doi: 10.18632/oncotarget.27545. eCollection 2020 Apr 07.

SYK has been reported to possess both tumour promotor and repressor activities and deletion has been linked to a pro-proliferative / pro-invasive phenotype in breast tumours. It is unclear whether this is a consequence of protein deletion or loss...

Inhibition of SYK and cSrc kinases can protect bone and cartilage in preclinical models of osteoarthritis and rheumatoid arthritis.

Scientific reports

Novikov FN, Panova MV, Titov IY, Stroylov VS, Stroganov OV, Chilov GG.
