    • This invention provides pharmaceutical compositions and methods for controlling and modifying Natural Killer (NK) cell and T cell functions by manipulation of "mast cell function-associated antigen", or "MAFA", polypeptide-mediated cell signaling. The invention provides pharmaceutical compositions and methods using an agent that specifically binds to an MAFA ligand on a target cell and prevents or inhibits NK- or T cell-expressed cell surface MAFA from binding to the MAFA ligand on the target cell. Preventing or inhibiting an NK- or a T cell-expressed cell surface MAFA from binding to the MAFA ligand on the target cell prevents or inhibits the cell surface MAFA from generating an inhibitory signal to the NK or the T cell. The invention also provides pharmaceutical compositions and methods using an agent that specifically binds to an NK- or a T cell-expressed cell surface MAFA and prevents or inhibits the NK- or T cell-expressed cell surface MAFA from binding to a MAFA ligand or generating an inhibitory signal to the NK or the T cell. The invention also provides pharmaceutical compositions and methods using an agent that specifically binds to an NK- or a T cell-expressed cell surface MAFA and inhibits an NK cell or T cell activity.
    • 本发明提供了通过操纵“肥大细胞功能相关抗原”或“MAFA”,多肽介导的细胞信号传导来控制和修饰天然杀伤(NK)细胞和T细胞功能的药物组合物和方法。 本发明提供药物组合物和方法,其使用特异性结合靶细胞上的MAFA配体并阻止或抑制NK细胞或T细胞表达的细胞表面MAFA与靶细胞上的MAFA配体结合的试剂。 预防或抑制NK细胞或T细胞表达的细胞表面MAFA与靶细胞上的MAFA配体的结合阻止或抑制细胞表面MAFA向NK细胞或T细胞产生抑制性信号。 本发明还提供了药物组合物和方法,其使用特异性结合NK-或T细胞表达的细胞表面MAFA并阻止或抑制NK-或T细胞表达的细胞表面MAFA与MAFA配体结合或产生 对NK或T细胞的抑制信号。 本发明还提供了使用特异性结合NK-或T细胞表达的细胞表面MAFA并抑制NK细胞或T细胞活性的药剂的药物组合物和方法。
