Pathogenic immune response to therapeutic factor VIII: exacerbated response or failed induction of tolerance?

open access: yesHaematologica, 2019
Therapeutic factor VIII is highly immunogenic. Despite intensive research in the last decades, the reasons why 5-30% of patients with hemophilia A (of all severities) develop inhibitory anti-factor VIII antibodies (inhibitors) following replacement ...

Recombinant porcine factor VIII: Lessons from the past and place in the management of hemophilia A with inhibitors in 2021

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2021
The most serious complication of factor VIII (FVIII) replacement therapy is the occurrence of anti‐FVIII alloantibodies that can strongly reduce or abolish the effect of human FVIII products.

The inactivation of factor VIII in vitro [PDF]

open access: yes, 1972
When normal citrated plasma is stored at 37° C and pH 7.8 the factor VIII activity drops to about 50% of its initial value during the first 8-12 h. In the following 4 days practically no further drop in activity is found.

Extrahepatic sources of factor VIII potentially contribute to the coagulation cascade correcting the bleeding phenotype of mice with hemophilia A

open access: yesHaematologica, 2015
A large fraction of factor VIII in blood originates from liver sinusoidal endothelial cells although extrahepatic sources also contribute to plasma factor VIII levels.

Where Are the Baryons? III: Non-Equilibrium Effects and Observables [PDF]

open access: yesAstrophys.J.650:573-591,2006, 2005
Numerical simulations of the intergalactic medium have shown that at the present epoch a significant fraction (40-50%) of the baryonic component should be found in the (T~10^6K) Warm-Hot Intergalactic Medium (WHIM) - with several recent observational lines of evidence indicating the validity of the prediction.

Self-ionizing galactic winds [PDF]

open access: yes, 2022
We present hydrodynamical simulations of galactic winds from star-forming galaxies including non-equilibrium ionization and frequency-dependent radiative transfer, processes that have remained largely unaccounted for in galactic wind studies. We consider radiation from massive stars, the metagalactic UV/X-ray background, and the self-radiation of the ...

Attempted spleen transplant in classical hemophilia [PDF]

open access: yes, 1969
Recent evidence has indicated that the spleen may be partly responsible for synthesis or storage of antihemophilic factor (factor VIII) in dogs (8) and in man (2). Transplantation of the spleen into dogs with congenital deficiency of factor VIII has been

Factor VIII/V C-domain swaps reveal discrete C-domain roles in factor VIII function and intracellular trafficking

open access: yesHaematologica, 2017
Factor VIII C-domains are believed to have specific functions in cofactor activity and in interactions with von Willebrand factor. We have previously shown that factor VIII is co-targeted with von Willebrand factor to the Weibel-Palade bodies in blood ...

The 1.7 Å X-ray crystal structure of the porcine factor VIII C2 domain and binding analysis to anti-human C2 domain antibodies and phospholipid surfaces. [PDF]

open access: yesPLoS ONE, 2015
The factor VIII C2 domain is essential for binding to activated platelet surfaces as well as the cofactor activity of factor VIII in blood coagulation. Inhibitory antibodies against the C2 domain commonly develop following factor VIII replacement therapy

Importance of factor-IX-dependent prothrombinase formation - the Josso Pathway,- in clotting plasma [PDF]

open access: yes, 1989
We report a study on the importance of factor IX activation in thromboplastin-dependent coagulation in plasma. Diluted, CaCl2-containing thromboplastin solutions at constant phospholipid concentration were used to trigger the coagulation in plasma from ...
