免疫应作抗原物质进入机体,激发免疫系统发生一系列反应以排除该抗原的过程称免疫应答。其中主要反应是免疫细胞识别抗原而活化、增殖、分化,以致产生免疫效应。根据效应机理的不同,分为体液免疫和细胞免疫。免疫细胞所有参与免疫应答或与免疫应答有关的细胞通称免疫细胞。包括造血干细胞、淋巴细胞、单核吞噬细胞系统和粒细胞等。体液免疫体液(血浆、淋巴、组织液等)中所含的抗体(B细胞产生的)的特异性免疫。这种抗体可游离在体液中,也可与细胞结合。细胞免疫T淋巴细胞参与的并且与出生时胸腺
Immune antigens should be entered into the body, stimulate the immune system to a series of reactions to rule out the antigen process called immune response. The main reaction is that the immune cells recognize the antigen and activate, proliferate and differentiate so as to produce the immune effect. According to the different mechanism of action, divided into humoral and cellular immunity. All immune cells involved in the immune response or with the immune response-related cells known as immune cells. Including hematopoietic stem cells, lymphocytes, mononuclear phagocyte systems and granulocytes. Antibody (B cell-derived) specific immunity contained in humoral immune body fluid (plasma, lymph, tissue fluid, etc.). This antibody can be free in the body fluid can also be combined with the cells. Cellular immune T lymphocytes are involved and with the thymus at birth
