Compositions and methods useful for the diagnosis and treatment of heparin induced thrombocytopenia/thrombosis

The invention includes compositions, kits and methods comprising a monoclonal antibody which shares key functional properties with the polyclonal antibodies which participate in the pathogenesis of heparin induced thrombocytopenia / thrombosis (HIT / HITT) in a mammal. The monoclonal antibody of the invention preferentially binds with a PF4 / heparin complex relative to the binding of the antibody with PF4 or heparin alone. The monoclonal antibody of the invention also binds specifically with PF4 in a complex with other glycosaminoglycans besides heparin, and also activates platelets. The monoclonal antibody of the invention is useful in methods for diagnosing and treating HIT / HITT in a mammal. A humanized version of the monoclonal antibody of the invention is also included, along with a process for humanizing the monoclonal antibody of the invention.

Application of rLZ-8 in treating thrombopenia and preparation thereof

The invention provides a novel application of a recombinant ganoderma lucidum immunological regulation protein (rLZ-8) in treating thrombopenia. In the experiments of preventing and treating the thrombopenia of rats and dogs caused by cyclophosphamide, the rLZ-8 prepared from physiological saline carries out administration on an experimental animal model with lower thrombocytes, THPO and IL-6 are used as positive medicines, continuous administration is carried out, the number of the thrombocytes in blood is detected, the changes of the number of the thrombocytes before and after therapy are contrasted, and the medicine effect is analyzed. Compared with a model group, the rLZ-8 medicine group already obviously stimulates the thrombocyte proliferation of rats, Guinea pigs and dogs in the initial period (the 3rd day to the 5th day) of the administration, the difference is very obvious, the thrombocytes are recovered to a normal level in the middle period (the 7th day to the 10th day) of the administration, and the invention also obtains a very good effect in treating the thrombopenia of a Guinea pig experimental animal model caused by injecting anti-thrombocyte serum.

Application of phosphatidylserine (PS) blocking agent to preparation of medicines for treating platelet number reduction related diseases

The invention discloses application of phosphatidylserine (PS) blocking agent to preparation of medicines for treating platelet number reduction related diseases. The invention proves that PS exposurecaused by apoptotic and activated platelets promotes that the platelets are eliminated in liver through experiments for the first time. Research proves that the platelets in the body of a patient suffering from thrombocytopenia are subjected to both activation and apoptosis, and apoptosis and activation cause the PS of the platelets to be exposed, so that the platelets are swallowed by phagocyticcells in the liver. Closing of the PS or blockage of PS extroversion can inhibit the platelets from being eliminated, which indicates that the PS blocking agent can take part in the treatment processof the platelet number change related diseases and can inhibit platelet number reduction in peripheral circulation blood. Therefore, the invention discloses a mechanism for eliminating the plateletsthrough the PS extroversion; furthermore, the blocking agent for inhibiting from eliminating PS exposure dependency platelets has the potential to be developed into novel platelets protective medicines and medicines for treating thrombocytopenia, and has great scientific research and economic value.
