The Impact of Menopause on Immune Senescence
نویسندگان
چکیده
Several lines of evidence suggest that ovarian steroids modulate immune function in women. Women are at higher risk of autoimmune disease than men; generate more robust humoral responses to vaccination than men; and plasma cytokine levels and the immune response to certain vaccines change throughout the menstrual cycle. Aging is accompanied by a decline in immunity referred to as “immune senescence” that significantly contributes to increased morbidity and mortality in the elderly. Aging is also associated with menopause, one of the most dramatic age-related physiological changes in women. Given the strong evidence for sex differences in immune function between pre-menopausal adult women and men, it has been suggested that the loss of ovarian steroids associated with menopause might contribute to decreased immune function in post-menopausal women. However, we do not yet fully understand the interplay between ovarian and immune senescence. In this article, we review studies that have investigated the impact of menopause and hormone therapy on changes in immune function.

Is There any Mean to Postpone The Menopausal Ovarian Senescence?
The ovarian reserve (OR) gradually decreases throughout the female fertile life. This continuous depletion in OR is irreversible. This occurs through a programmed cell death known apoptosis. Some factors hasten such depletion such as chemo- and radiotherapy. Others have been investigated in trials to preserve the OR including gonadotropins, cytokines, growth hormones, nitric oxide and reorganiz...
متن کاملImpact of Estrogen Therapy on Lymphocyte Homeostasis and the Response to Seasonal Influenza Vaccine in Post-Menopausal Women
It is widely recognized that changes in levels of ovarian steroids modulate severity of autoimmune disease and immune function in young adult women. These observations suggest that the loss of ovarian steroids associated with menopause could affect the age-related decline in immune function, known as immune senescence. Therefore, in this study, we determined the impact of menopause and estrogen...
متن کاملImpact of Exogenous Spermine Application on the Vase Life of Cut Rose Flowers ‘Dolce Vita’
Senescence is an integral part of the normal developmental cycle of plants and can be traced in cell, tissue and organ level. This work was focused on the efficiency of post-harvest treatment with the free polyamine spermine (Spm) to extend the vase life of cut rose flowers as an anti-senescence compound. Spm treatment was applied at the rates of 0, 1, 2 and 4 mM. Some morphological, biochemica...
متن کاملAutoimmune diseases and reproductive aging.
As the population ages, more individuals with autoimmune diseases are experiencing reproductive senescence. Understanding the impact of menopause and age-related androgen decline on disease onset and course, as well as the potential for hormonal interventions, is critically important. In men, lupus erythematosis (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS) are associated with l...
