造成免疫系统抑制的常用手段包括电离辐射和环磷酰胺、可的松等药物处理。这类处理常常伴有较为广泛而严重的副作用,且对细胞免疫和体液免疫两者均有抑制效应。为专门研究T淋巴细胞及细胞免疫反应,可采用早期人工手术摘除胸腺,但这种处理特征是造成胸腺及细胞免疫活性彻底丧失
Common means of suppressing the immune system include ionizing radiation and drug treatments such as cyclophosphamide and cortisone. This type of treatment is often accompanied by more extensive and serious side effects and has an inhibitory effect on both cellular and humoral immunity. To specifically study T lymphocytes and cellular immune responses, thymectomy may be performed using early artificial surgeries, but this treatment is characterized by the complete loss of thymus and cellular immune activity
