配合尺寸公差中心范围加工法的应用与研究

Recently , dendritic cells ( DCs ) are found to play a dual role in the immunological system . Apart from inducing immune response as antigen presenting cells ( APCs ), DCs can also induce central and peripheral tolerance .

近年来，树突状细胞（Dendriticcells，DCs）被发现在免疫系统中扮演着双重角色，除作为抗原提呈细胞（Antigenpresentingcells，APC）诱发免疫反应外，还能诱导中枢或周围性免疫耐受。

But at present , neither the central nor the peripheral tolerance strategies get great achievement because of the complicated manipulation method or unsure effects .

但目前无论是中央型还是外周型耐受均因操作复杂或效果不确定而无法奏效。
