Provided are chimeric Protein C-Factor VII proteins comprising a Gla domain from Protein C (PC), an EGF-1 domain from PC, an EGF-2 domain from Factor VII (FVII), and a protease domain from FVII.

An isolated peptide of up to 6 amino acids comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR is disclosed. Also disclosed is an isolated peptide comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR, wherein the peptide comprises a modification in at least one amino acid. Also disclosed is a molecule comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR attached to a heterologous moiety. Pharmaceutical compositions and methods of treatment are also disclosed.

Materials and methods of in vivo possessing of target proteins in plants by co-expressing with proprotein processing enzyme, human Furin, are provided. A method of expressing highly soluble and functional active human Furin in plants also is provided.

Methods for treating and/or preventing choroidal neovascularization (CNV) or retinal leakage associated with CNV are disclosed, comprising the use of activated protein C (APC) and/or an APC variant. A disclosed method may be applied in the treatment or prevention of ocular diseases, disorders or conditions that are caused directly by CVN, feature development of CNV as a secondary stage or a complication thereof, and/or feature CNV as a synchronous or asynchronous sequela thereof. An exemplary disease treatable by a disclosed method is neovascular age-related macular degeneration (nAMD).

This disclosure provides materials and methods for treating or preventing graft-versus-host-disease (GVHD) using protein C or activated protein C or a signaling-selective variant or mutant thereof.

The present disclosure relates to cells, tissues, organs, and/or animals having one or more modified genes for enhanced xenograft survival and/or tolerance. In addition, the present disclosure relates to methods of making and using the cells, tissues, organs, and/or animals having one or more of the modified genes.

The invention provides a polypeptide or a partial polypeptide thereof, containing an amino acid sequence represented by the formula:

A.sub.1A.sub.2A.sub.3(I)

wherein A.sub.1 is an amino acid sequence comprising an amino acid sequence of a light chain of protein C or a homologue thereof, A.sub.2 is an amino acid sequence constituting a self-cleaving site, and A.sub.3 is an amino acid sequence comprising an amino acid sequence of a heavy chain of protein C or a homologue thereof, wherein a dimeric protein or partial protein thereof consisting of fragments on the N-terminal side and C-terminal side of the cleavage site of A.sub.2, has protein C activity. The polypeptide or partial polypeptide thereof makes it possible to 1) produce activated protein C as a recombinant preparation, and 2) link same to effective gene therapy for protein C deficiency.

The present disclosure relates to cells, tissues, organs, and/or animals having one or more modified genes for enhanced xenograft survival and/or tolerance. In addition, the present disclosure relates to methods of making and using the cells, tissues, organs, and/or animals having one or more of the modified genes.
