  • Patent number: 11173194
    Abstract: Antibodies binding to sites on the alpha-subunit of the (Na++K+)-ATPase increase cardiac contraction of both ventricular myocytes and mouse heart. In particular, antibodies binding to the RSATEEEPPNDD (SEQ ID NO: 1) or DVEDSYGQQWTYEQR (SEQ ID NO: 2) peptides (or isoforms/derivatives thereof) of the alpha-subunit of the (Na++K+)-ATPase, have been found to be highly inotropic. Both the antibodies and the peptides are important for the treatment of human heart failure and other contractile disorders.

  • Patent number: 10214583
    Abstract: Antibodies that are agonists of sodium pump (Na+/K+ ATPase; NKA) activity are provided. In particular, antibodies that specifically bind epitopes on the beta-1 (?1) subunit of NKA are disclosed. These antibodies have the ability to increase the activity of the catalytic alpha subunit of NKA upon ?1 subunit binding. Due to their activity, the antibodies also have the ability to trigger a positive inotropic effect in cardiac tissues (i.e., increase cardiac contraction). The present invention thus includes, but is not limited to, NKA ?1 subunit peptide epitopes, antibodies that specifically bind the epitopes, methods of increasing NKA activity and cardiac contraction through administration of the peptide vaccines or the antibodies, and methods of treating and/or preventing heart disease through administration of the peptides or the antibodies.
