Abstract
Multiple epidemiologic studies have revealed that gender is considered one of the important factors in the frequency and severity of certain infectious diseases, in which estrogens may play a vital role. There is growing evidence that estrogens as female sex hormone can modulate multiple biological functions outside of the reproductive system, such as in brain and cardiovascular system. However, it is largely unknown about the roles and mechanisms of estrogens/estrogen receptors in immune health and infection disease. Thence, by reading a lot of literature, we summarized the regulatory mechanisms of estrogens/estrogen receptors in immune cells and their roles in certain infectious diseases with gender differences. Therefore, estrogens may have therapeutic potentials to prevent and treat these infectious diseases, which needs further clinical investigation.

Abstract
Abstract
Estrogens affect the development, maturation, and function of multiple organ systems, including the immune system. One of the main targets of estrogens in the immune system is the thymus, which undergoes atrophy and phenotypic alterations when exposed to elevated levels of estrogen. To determine how estrogens influence the thymus and affect T cell development, estrogen receptor α (ERα) knockout (ERKO) mice were examined. ERKO mice have significantly smaller thymi than their wild-type (WT) littermates. Construction of ER radiation bone marrow chimeras indicated that the smaller thymi were due to a lack of ERα in radiation-resistant tissues rather than hemopoietic elements. ERKO mice were also susceptible to estradiol-induced thymic atrophy, but the extent of their atrophy was less than what was seen in WT mice. The estradiol-treated ERKO mice failed, however, to manifest alterations in their thymic CD4/CD8 phenotypes compared with WT mice. Therefore, ERα is essential in nonhemopoietic cells to obtain a full-sized thymus, and ERα also mediates some of the response of the thymus to elevated estrogen levels. Finally, these results suggest that in addition to ERα, another receptor pathway is involved in estradiol-induced thymic atrophy.

Abstract
Abstract
We examined the expression of the H4 T cell activation marker in thymic T cell subpopulations and found that TCR-αβ+ CD4+ thymic T cells are segregated into three subpopulations based upon H4 levels. Thymic T cells with either no or low H4 expression differentiate via the mainstream differentiation pathway in the thymus. H4int thymic T cells, which express a skewed Vβ repertoire of Vβ2, -7, and -8 in their TCRs, show the phenotype of NKT cells: CD44high, Ly6Chigh, NK1.1+, and TCR-αβlow. H4high thymic T cells also show a skewed Vβ repertoire, Vβ2, -7, and -8, and predominantly express an invariant Vα14-Jα281+ α-chain in their TCRs but constitute a distinct population in that they are CD44int, Ly6C−, NK1.1−, and TCR-αβhigh. Thus, invariant Vα14+ thymic T cells consist of ordinary NKT cells and a new type of T cell population. Vβ7+ and Vβ8.1+ invariant Vα14+ thymic T cells are present in DBA/2 mice, which carry mammary tumor virus-7-encoded superantigens, in comparable levels to those in BALB/c mice. Furthermore, Vβ7+ invariant Vα14+ thymic T cells in DBA/2 mice are in the immunologically responsive state, and Yersinia pseudotuberculosis-derived mitogen-induced Vβ7+ invariant Vα14+ thymic T cell blasts from DBA/2 and BALB/c mice exhibited equally enhanced responses upon restimulation with Y. pseudotuberculosis-derived mitogen. Thus, invariant Vα14+ thymic T cells that escape negative selection in DBA/2 mice contain T cells as functionally mature as those in BALB/c mice.

Abstract
Abstract
Glucocorticoid hormones modulate T cell maturation in vivo. While low levels of hormones are required for appropriate T cell development, high levels of glucocorticoid hormones target immature developing thymocytes for cell death during systemic stress. In this report, we propose a molecular mechanism for the induction of apoptosis in CD4+CD8+ double-positive thymocytes by dexamethasone in vivo. Dexamethasone injection induced the expression of IκBα and IκBβ in thymocytes and down-regulated NF-κB DNA binding activated by intrathymic signals. Down-regulation of NF-κB DNA binding preceded cell death, suggesting that NF-κB may be important for the survival of immature thymocytes. In addition, ex vivo treatment of thymocyte single-cell suspension with dexamethasone accelerated p65/RelA down-regulation and cell death. Conversely, NF-κB induction diminished dexamethasone-induced death. Expression of the c-myc proto-oncogene, a NF-κB target, was also reduced in thymocytes of dexamethasone-treated animals, and ectopic transgenic expression of c-myc in mice provided partial rescue of double-positive thymocytes from dexamethasone mediated cell death. These observations suggest that viability of CD4+CD8+ thymocytes may be maintained by an NF-κB/c-myc-dependent pathway in vivo.
