一、外源性干扰素的局限性和内源性干扰素干扰素(IFN)为一类蛋白质,系宿主细胞通过病毒等或其他人工合成的诱生剂的诱导而产生有抑制病毒增殖的作用。产生 IFN 的细胞主要为网状内皮细胞、白细胞和淋巴细胞,其他细胞也可产生。体外实验证明,IFN 具有提高巨噬细胞、天然杀伤细胞(NK 细胞),以及抗体依赖性(ADCC)细胞毒活力的效应。但外源性 IFN 在 First, the limitations of exogenous interferon and endogenous interferon (IFN) as a class of proteins, the Department of host cells through the virus or other synthetic inducer induced inhibition of the proliferation of the virus . IFN-producing cells are mainly reticuloendothelial cells, leukocytes and lymphocytes, other cells can also be produced. In vitro experiments have shown that IFN has the effect of increasing the cytotoxic activity of macrophages, natural killer cells (NK cells), and antibody-dependent (ADCC). But exogenous IFN in
