The primary and secondary immune responses to sheep erythrocytes (SRBC) have been characterized in the tortoise Mauremys caspica in terms of circulating antibodies and PFC response in two different seasons: summer and autumn. Primary immunization is followed by the appearance of both 2ME-sensitive antibodies and splenic PFCs in autumn but not in summer. During the secondary response, 2ME-resistant antibodies were found in both seasons, but the number of PFCs was significantly reduced during summer. The results are discussed from the perspective of the role played by glucocorticosteroids in the seasonal variations affecting reptilian immunoreactivity.
已在陆龟(埃及陆龟)中,就两个不同季节(夏季和秋季)循环抗体和PFC反应方面,对绵羊红细胞(SRBC)的初次和二次免疫反应进行了表征。初次免疫后,秋季出现了对2-巯基乙醇敏感的抗体和脾脏PFC,但夏季未出现。在二次反应期间,两个季节均发现了对2-巯基乙醇耐药的抗体,但夏季PFC的数量显著减少。从糖皮质激素在影响爬行动物免疫反应性的季节性变化中所起作用的角度对结果进行了讨论。
