摘要
Immunohistochemical analysis of the expression of proapoptotic protein P53 and proliferation protein Ki-67 in human pineal gland showed that in people over 60 years pinealocyte proliferation is virtually absent. Moreover, pinealocyte apoptosis is more pronounced in elderly, whereas in senile and long-living individuals its intensity decreases.
