The present disclosure relates to methods and compositions for the treatment of a mammalian subject suffering from lupus the method comprising, administering to said subject a therapeutically effective amount of an orthogonal CAR-T cell directed against a B-cell antigen in combination with an engineered orthogonal IL2 ligand that selectively activates orthogonal CAR T cell expressing an engineered orthogonal CD122 receptor. In some embodiments, the lupus is systemic lupus erythramatosis (SLE). In some embodiments, the lupus is lupus nephritis. In some embodiments the subject suffering from lupus is also suffering from cytopenia. In some embodiments the methods are practiced in the absence of prior lymphodepletion of the subject.

The invention discloses a wolfberry-astragalus compound polysaccharide with an anti-myelosuppression effect as well as a preparation method and application of the wolfberry-astragalus compound polysaccharide. The wolfberry-astragalus compound polysaccharide is prepared by adopting a process of separately extracting wolfberry polysaccharide and astragalus polysaccharide and then mixing, the total sugar content is 70-80%, the uronic acid content is 10-14%, and the wolfberry-astragalus compound polysaccharide has specific molecular weight distribution and monosaccharide composition characteristics. Animal experiment results show that the wolfberry and astragalus compound polysaccharide can significantly improve peripheral hemopenia of myelosuppression mice induced by cyclophosphamide, promote recovery of the number of leukocytes, lymphocytes, monocytes and neutrophils, and effectively reverse weight loss caused by chemotherapeutic drugs. The wolfberry-astragalus compound polysaccharide provided by the invention is high in safety and remarkable in anti-myelosuppression effect, and can be used for preparing medicines or functional preparations for improving myelosuppression related diseases.

Methods and compositions containing a phorbol ester or a derivative of a phorbol ester in combination with G-CSF or in combination with EPO, are provided for the treatment of cytopenia in mammalian subjects. The compositions and methods also reduce the duration of cytopenia such as neutropenia, thrombocytopenia, and / or anemia.

This invention discloses a traditional Chinese medicine composition for treating neutropenia and / or T-cell cytopenia, its preparation method, and its application. The composition mainly consists of Astragalus membranaceus, Angelica sinensis, ginseng / Codonopsis pilosula, Ganoderma lucidum, Lycium barbarum, and Glycyrrhiza uralensis in a specific ratio. It has a dual effect of increasing neutrophil count and promoting thymic development and T-cell function (enhancing T-cell function). Through multiple pathways, including stimulating hematopoietic progenitor cell proliferation and differentiation, improving the thymic microenvironment, and activating innate and adaptive immunity, it effectively improves the state of reduced immune cells and enhances the body's anti-infection ability.

The invention features methods of treating a transfusion dependent subject having myelofibrosis, a cytopenia associated with myelofibrosis, such as anemia, thrombocytopenia, or neutropenia, or receiving treatment with a cytopenia-associated myelofibrosis treatment by administering to the subject an activin receptor type II (ActRII) signaling inhibitor, optionally in combination with a cytopenia- associated myelofibrosis treatment. The ActRII signaling inhibitor may be an antibody that binds to an ActRII ligand, an ActRII antibody, or an ActRII ligand trap.

There is provided a method of treating an immune cytopenia in a subject in need thereof, the method comprising administering a therapeutically effective amount of a compound of formula (I) wherein R1, R2, R3 and R4 are as defined herein.
