Recombinant Fibrinogen C Domain Containing 1 (rFibcd1) proteins and methods for using the same in the treatment of muscle atrophy are provided as are vectors, host cells, pharmaceutical compositions and modified RNA molecules encoding the rFibcd1 proteins.

The present invention relates to compositions comprising fibrinogen gamma prime variants for use in the treatment or prevention of an infection and methods of administering the composition. The fibrinogen gamma prime variants in the composition comprise at least one fibrinogen gamma prime polypeptide chain. The compositions for use according to the invention may also comprise other fibrinogen variants. Compositions comprising fibrinogen gamma prime variants according to the invention improve survival time after infection up to more than 200 percent compared to WT fibrinogen. They may be used both therapeutically and prophylactically.

The invention is directed to biological response modifiers (BRM) which may contain one or more compounds, and to methods for enhancement of an immune system with BRMs of the invention including augmenting a specific immune response either prophylactically or for treatment, as an adjuvant or vaccine when coupled with a pathogenic antigen, and for boosting an immune system generally. The invention is also directed to the reduction of an unrestrained or improper inflammatory response and/or an immune response such as to treat or prevent autoimmune diseases and disorders, and associated symptoms. Further, the invention is directed to the manufacture of BRM compounds comprising isolated serum from a mammal, and subjecting that serum to tangential flow chromatography and molecular weight cut-off dialysis to obtain one or more purified BRM compounds suitable for administration to a patient in need.
