Structural, Ionic, and Electronic Properties of Solid-State Phthalimide-Containing Polymers for All-Organic Batteries.

Redox-active polymers serving as the active materials in solid-state electrodes offer a promising path toward realizing all-organic batteries. While both cathodic and anodic redox-active polymers are needed, the diversity of the available anodic materials is limited. Here, we predict solid-state structural, ionic, and electronic properties of anodic, phthalimide-containing polymers using a multiscale approach that combines atomistic molecular dynamics, electronic structure calculations, and machine learning surrogate models.

PEGylation of a factor VIII-phosphatidylinositol complex: pharmacokinetics and immunogenicity in hemophilia A mice.

Hemophilia A is an X-linked bleeding disorder caused by the deficiency of factor VIII (FVIII). Exogenous FVIII is administered therapeutically, and due to a short half-life, frequent infusions are often required. Fifteen to thirty-five percent of severe hemophilia A patients develop inhibitory antibodies toward FVIII that complicate clinical management of the disease.

Phosphatidylinositol induces fluid phase formation and packing defects in phosphatidylcholine model membranes.

Liposomes consisted of phosphatidylinositol (PI) and phosphatidylcholine (PC) have been utilized as delivery vehicle for drugs and proteins. In the present work, we studied the effect of soy PI on physical properties of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) liposomes such as phase state of lipid bilayer, lipid packing and phase properties using multiple orthogonal biophysical techniques. The 6-dodecanoyl-2-dimethylamino naphthalene (Laurdan) fluorescence studies showed that presence of PI induces the formation of fluid phases in DMPC.

Downregulation of CD40 signal and induction of TGF-β by phosphatidylinositol mediates reduction in immunogenicity against recombinant human Factor VIII.

Factor VIII (FVIII) is an important coagulation cofactor and its deficiency causes Hemophilia A, a bleeding disorder. Replacement therapy using recombinant FVIII is currently the first line of therapy for Hemophilia A, but the development of neutralizing antibody is a major clinical complication for this therapy. Recently, it has been shown that FVIII associated with phosphatidylinositol (PI)-containing lipidic nanoparticles reduced development of neutralizing antibodies in Hemophilia A mice (Peng A, Straubinger RM, Balu-Iyer SV.

Immunogenicity and pharmacokinetic studies of recombinant factor VIII containing lipid cochleates.

Replacement therapy using recombinant factor VIII (rFVIII) is currently the most common therapy for hemophilia A, a bleeding disorder caused by the deficiency of FVIII. However, 15-30% of patients develop inhibitory antibodies against administered rFVIII, which complicates the therapy. Encapsulation or association of protein with lipidic structures can reduce this immune response.

Phosphatidylserine reduces immune response against human recombinant Factor VIII in Hemophilia A mice by regulation of dendritic cell function.

A major clinical complication in the treatment of Hemophilia A using exogenously administered recombinant Factor VIII (FVIII) is the development of neutralizing antibodies. It has been shown previously that FVIII complexed with phosphatidylserine (PS) reduces the development of total and neutralizing antibody titers in hemophilic mice. The effect of complexation of FVIII with PS upon dendritic cell (DC) uptake, maturation and processing, T-cell proliferation and cytokine secretion profiles was investigated.

Phosphatidylinositol containing lipidic particles reduces immunogenicity and catabolism of factor VIII in hemophilia a mice.

Factor VIII (FVIII) is an important cofactor in blood coagulation cascade. It is a multidomain protein that consists of six domains, NH2-A1-A2-B-A3-C1-C2-COOH. The deficiency or dysfunction of FVIII causes hemophilia A, a life-threatening bleeding disorder.

Effect of route of administration of human recombinant factor VIII on its immunogenicity in Hemophilia A mice.

Factor VIII is a multi-domain glycoprotein and is an essential cofactor in the blood coagulation cascade. Its deficiency or dysfunction causes Hemophilia A, a bleeding disorder. Replacement using exogenous recombinant Factor VIII (FVIII) is the first line of therapy for Hemophilia A.

Development and characterization of lipidic cochleate containing recombinant factor VIII.

Hemophilia A, a life-threatening bleeding disorder, is caused by deficiency of factor VIII (FVIII). Replacement therapy using rFVIII is the first line therapy for hemophilia A. However, 15-30% of patients develop neutralizing antibody, mainly against the C2, A3 and A2 domains.
