人类恶液质因子是由157个氨基酸组成的单个多肽,其分子量约为17000道尔顿,属于单核素,是一种与其他淋巴因子一样的杀伤因子。恶液质因子是机体受内毒素、某些寄生虫的细胞溶解产物及病毒颗粒刺激后由巨噬细胞释放的。极低浓度的恶液质因子可提高免疫力,刺激嗜中性白细胞产生氧自由基,促进嗜中性白细胞粘附于内皮细胞表面,促使内皮细胞、单核细胞释放IL-I,增加白细胞的杀伤力。但恶液质因子大量释放时则因它对多种组织和器官均有高度的亲和性,可通过特异受体与组织、器官的细胞结合,导致脏器破坏
Human cortisol is a 157 amino acid polypeptide consisting of a single molecule with a molecular weight of about 17,000 daltons and belonging to the mononuclear hormone that is the same as other lymphokines. Cacao factor is the body by the endotoxin, some parasite cell lysate and virus particles released by the macrophages. Very low concentration of catechin can improve immunity, stimulate neutrophils to produce oxygen free radicals, and promote the adhesion of neutrophils to the endothelial cell surface, prompting endothelial cells, monocytes release of IL-I, increased leukocyte Lethality. However, when a large number of evil liquid factor is released due to its high degree of affinity for a variety of tissues and organs, through specific receptors and tissues, organs, cells, resulting in organ damage
