免疫应答是通过T、B淋巴细胞和巨噬细胞之间的复杂协同作用实现的。细胞之间的信息传递,一方面通过细胞之间的直接接触,另一方面是由细胞释放的可溶性因子介导的。最近发现可溶性因子中的白细胞间介素(Interleukin,IL)参与淋巴细胞的分裂、增殖、分化和成熟,引起人们的关注,认为它是支配淋巴细胞增殖、分化的细胞相互作用的因子。现在已知IL有三种:巨噬细胞产 The immune response is through complex synergy between T, B lymphocytes and macrophages. Information transmission between cells, on the one hand through direct contact between cells, on the other hand is mediated by soluble factors released by cells. Recently, it has been found that Interleukin (IL), a soluble factor, is involved in the division, proliferation, differentiation and maturation of lymphocytes, and is attracting attention as a factor that controls the cell-cell interactions of lymphocyte proliferation and differentiation. There are now three known ILs: macrophage production
