Abstract
Systems and methods for purification and concentration of autologous alpha-2 macroglobulin (A2M) from whole blood and or recombinant A2M are provided. Also provided are methods of treating wounds with A2M. Methods for utilizing A2M in combination with other treatments (e.g., platelets and other growth factors) are provided in addition to combinations with exogenous drugs or carriers. Also provided is a method of producing recombinant A2M wild type or variants thereof where the bait region was modified to enhance the inhibition characteristics of A2M and/or to prolong the half-life of the protein for treating wounds.
Claims19
A method for the treatment or prophylaxis of a chronic wound in a mammalian subject, comprising topically applying to the chronic wound an effective amount of a composition comprising a recombinant alpha-2-macroglobulin polypeptide (A2M) comprising a non-natural bait region that replaces a wild-type A2M bait region.
A wound dressing comprising an effective amount of a composition for the treatment or prophylaxis of a chronic wound in a mammalian subject, wherein the composition comprises a recombinant alpha-2-macroglobulin polypeptide (A2M) comprising a non-natural bait region that replaces a wild-type A2M bait region.
