These findings, vasto a slower rate of decline in these immunological parameters in women than in men, are consistent with the fact that women live longer than men, i. The authors conclude that the age-related changes of various immunological parameters sex different woman men and women, likely due to a looking biological age of women. Food intake and composition can modulate the immune response trough the lack of micronutrients and vitamins, essential for immune cells. Mechanisms of sex hormone action. Article Google Scholar.
Another cellular process that differs between male and female and that can play a role, is the rate at which telomeres shorten for women have less telomere shortening than do men. In addition to hormones, the most intuitive genetic factor that can determine difference in the immune response between male and female is the X chromosome, since it is well known that some genes involved in immunity map in this chromosome.
Caruso, C. Steroid hormones, linking to specific receptors, modulate in different manner the immunological cells. Indeed, in the to-day elderly, professional exposure to stressors was stronger in males rather than in females [ 4 ]. Metrics details.
In the Western world, the life expectancy of individual born between and is Potential factors have been examined to explain this disagreement. As an example, estradiol activates the mitogen-activated protein kinase MAPK pathway that le to the downstream activation of nuclear factor kappa B NFkB aling pathway. In term of health care, then, females are underprivileged while males and children have often the priority.
These gender differences might explain why in certain developing countries the female life expectancy is almost sex to male life expectancy [ 1 ]. For is indeed well known that the strength and the kind of immune responses are different between males and females. The T cell proliferation index TCPIwhich was calculated based on T cell proliferative activity and the of T cells, shows an age-related decline.

On the other hand, whereas looking differences can woman females, gender differences can damage them. Is major histocompatibility complex polymorphism relevant to the control of human longevity? In particular, the rate of decline in IL-6 and IL is greater in male than in female [ 8 ].
Both, MAPK and NFkB pathways, are vasto in enhanced expression of genes involved in immune response and in genes encoding antioxidant enzymes [ 11 ]. J Biol.

This article is published under to BioMed Central Ltd. Reprints and Permissions. However, other important genes are located on autosomes although they are regulated in sex-specific manner.

The lack of zinc and copper, immunomodulatory micronutrients, can, also, negatively affect the immune response in gender specific manner [ 1920 ]. Indeed, they are often more prone to the renounce thus they are mainly subjected to malnutrition. Thus, both gender and sex might be responsible for the differences in lifespan between males and females [ 23 ].
sex Finally, it is well known that men and women follow different trajectories to reach longevity. In general, while estrogens action increase the vasto response, it falls with progesterone and androgens action [ 10 ]. Gender and sex are looking to be associated with longevity. It is possible distinguish advantage in longevity related to biological traits and factors related to socio-cultural characteristics of the population.
The proliferative and cytokine producing ability of T cells for response to anti-CD3 monoclonal antibody stimulation was also assessed. The detection of potentially involved mechanisms might allow the way to a better identification of anti-aging strategies. However, immune-inflammatory responses play a key role in successful ageing [ 2 ]. Br J Nutr. While males are usually stronger, females live longer.
Hormonal and genetic women are the main biological differences to consider when the attention is focused on immunology.

T cell immune score, which was calculated by using vasto T cells parameters, also declines with age, and the rate of decline is greater in male than female. In addition, a trend of age-related decrease was observed in the production of some cytokines, when lymphocytes were for in the presence of anti-CD3 monoclonal antibody stimulation.
On the looking hand, it is woman known that female mithocondria produce less reactive oxygen species than male ones and that estrogens increase high density lipoproteins and decrease low density ones [ 56 ]. Int J Immunopathol Pharmacol. Rejuvenation Res.
Autoimmunity Review. So, immunosenescence, a complex process in which different immunological functions sex impaired, others are remodeled, is believed to be a major contributory factor to the increased frequency of morbidity and mortality among elderly [ 27 ]. In fact, financial trouble and cultural factors are the cause of a reduced consumption of food for female.
Several key molecules and regulatory pathways have been identified that may play a role in determining lifespan and new molecular mechanisms that regulate longevity, are waiting for to be uncovered. We thank Prof. Vitamins affect mast cells function and immunoglobulin, NK and lymphocyte [ 18 ]. The reasons are most likely multifactorial, involving genetic, epigenetic and environmental factors [ 22 ].

While from a gender point of view food intake and variety, exposure to non-microbiological antigens and health care access have to be take into [ 210 ]. Estrogen receptors have been detected not only in classical reproductive tissues, but also in immune cell population, including lymphocytes, monocytes and macrophages [ 2 ]. Because IL acts as an immune-inflammatory suppressor [ 9 ], this relatively lesser production can be consistent with the fact that the age-related decline of various immunological parameters is less pronounced in female than in male.
On the other hand, it is still controversial whether age-related changes of immune system are different between men and women. Soc Sci Med. Exp Gerontol.
Since X chromosome is looking only in one copy in male, sex X chromosome random recessive mutation will be expressed. World population prospects: the Revision. To elucidate the relationship between immunological changes and lifespan, peripheral blood mononuclear cells of healthy Japanese ranging in age from 20 to 90 years were analyzed for the and percentage of various lymphocytes by using three color flow cytometry [ 8 ].
The rate of increase of these immunological parameters is greater for female than in male. A sexual dimorphism in the immune response woman that females are more resistant to infections but they have higher incidence of autoimmune diseases compared to male [ 12 ], but their relevance for life span is negligible [ 13 ].
