Gender-Related Immune-Inflammatory Factors, Age-Related Diseases, and Longevity

Abstract

This review discusses the role of estrogens as pro- or antiinflammatory players in immune-inflammatory responses. In particular, their role in Alzheimer’s disease (AD), an example of immune-inflammatory disease, is discussed briefly. AD is a progressive neurodegenerative disease, which in Western societies accounts for the majority of cases of clinical senile dementia. However, sexual dimorphism of diseases may also depend on factors independent of sex hormones (i.e., a gender effect), as demonstrated by our data on differential longevity in females and males. In fact, differences in mortality between men and women are not only a question of sex that refers to biological differences, but rather a question of ‘‘socially constructed sex,’’ a question of gender (i.e., the characteristics that a society or culture delineates as masculine or feminine). In gender medicine, we conclude that it is important to consider the role played both by hormones, customs, and educational levels regarding the different propensity of males and females to fall ill. So, in programming antiaging strategies, we have also to take these aspects into account
