Activation of β1 integrins and caveolin-1 by TF/FVIIa promotes IGF-1R signaling and cell survival.

The tissue factor/coagulation factor VIIa (TF/FVIIa) complex induces transactivation of the IGF-1 receptor (IGF-1R) in a number of different cell types. The mechanism is largely unknown. The transactivation leads to protection from apoptosis and nuclear translocation of the IGF-1R.

Adipocytes express tissue factor and FVII and are procoagulant in a TF/FVIIa-dependent manner.

Tissue factor (TF) combined with its ligand FVII initiates blood coagulation and intracellular signaling. Obese and type 2 diabetic subjects have increased TF expression in their adipose tissue and an increased risk for thrombotic complications. Here we address the role of TF/FVII on adipocyte functions.

Cationization increases brain distribution of an amyloid-beta protofibril selective F(ab') fragment.

Antibodies and fragments thereof are, because of high selectivity for their targets, considered as potential therapeutics and biomarkers for several neurological disorders. However, due to their large molecular size, antibodies/fragments do not easily penetrate into the brain. The aim of the present study was to improve the brain distribution via adsorptive-mediated transcytosis of an amyloid-beta (Aβ) protofibril selective F(ab') fragment (F(ab')-h158).

Tissue factor/factor VIIa signalling promotes cytokine-induced beta cell death and impairs glucose-stimulated insulin secretion from human pancreatic islets.

Aims/hypothesis: Patients diagnosed with type 1 or type 2 diabetes have elevated levels of coagulation factor VIIa (FVIIa) and its receptor tissue factor (TF) in their bloodstream. This may affect the fate of the beta cells. We aimed to study the effects of TF/FVIIa signalling on cytokine-induced beta cell death and islet function in vitro.

Prevalence trends of the new variant of Chlamydia trachomatis in four counties of Sweden in 2007-2011.

A new variant of Chlamydia trachomatis (nvCT) was discovered in Sweden in 2006, and it could not be detected by diagnostic systems from Abbott and Roche, whereas the third system used, from Becton Dickinson (BD), detects nvCT. We analyzed 3648 samples from 2 counties that used Roche and 2 counties that used BD methods from 2007 to 2011. After implementation of a Roche method that detects nvCT, its proportion has decreased and converged in the 4 counties but are still at different levels in Roche and BD counties.
