Abstract
Viral infections during pregnancy are a considerable cause of adverse outcomes and birth defects, and the underlying mechanisms are poorly understood. Among those, cytomegalovirus (CMV) infection stands out as the most common intrauterine infection in humans, putatively causing early pregnancy loss. We employed murine CMV as a model to study the consequences of viral infection on pregnancy outcome and fertility maintenance. Even though pregnant mice successfully controlled CMV infection, we observed highly selective, strong infection of corpus luteum (CL) cells in their ovaries. High infection densities indicated complete failure of immune control in CL cells, resulting in progesterone insufficiency and pregnancy loss. An abundance of gap junctions, absence of vasculature, strong type I interferon (IFN) responses, and interaction of innate immune cells fully protected the ovarian follicles from viral infection. Our work provides fundamental insights into the effect of CMV infection on pregnancy loss and mechanisms protecting fertility.

Abstract
Evidence shows coronavirus disease 2019 (COVID-19)-induced symptom severity and mortality is more frequent in men than in women, suggesting sex steroids may play a protective role. Female reproductive steroids, estrogen and progesterone, and its metabolite allopregnanolone, are anti-inflammatory, reshape competence of immune cells, stimulate antibody production, and promote proliferation and repair of respiratory epithelial cells, suggesting they may protect against COVID-19 symptoms.

Abstract
Severe outcomes and death from the novel coronavirus disease 2019 (COVID-19) appear to be characterized by an exaggerated immune response with hypercytokinemia leading to inflammatory infiltration of the lungs and acute respiratory distress syndrome. Risk of severe COVID-19 outcomes is consistently lower in women than men worldwide, suggesting that female biological sex is instrumental in protection. This mini-review discusses the immunomodulatory and anti-inflammatory actions of high physiological concentrations of the steroids 17β-estradiol (E2) and progesterone (P4). We review how E2 and P4 favor a state of decreased innate immune inflammatory response while enhancing immune tolerance and antibody production. We discuss how the combination of E2 and P4 may improve the immune dysregulation that leads to the COVID-19 cytokine storm. It is intended to stimulate novel consideration of the biological forces that are protective in women compared to men, and to therapeutically harness these factors to mitigate COVID-19 morbidity and mortality.

Abstract
This paper describes the reliable determination of progesterone (P4) in undiluted saliva making use of a disposable amperometric immunosensors implemented on low-cost and portable device/potentiostat constructed with commercial-off-the-shelf (COTS) components. The immunosensor allows the fast (45 min), selective and sensitive determination (5 pg mL-1 LOD) of P4 using amperometry in stirred solutions. The immunosensor was coupled to the COTS-based potentiostat and amperometry was made into drops of quiescent solutions. No significant differences were apparent between the analytical performance achieved with the immunosensor for P4 using both a conventional and the COST-based potentiostats. The practical applicability of the immunosensor coupled with the COTS-based potentiostat was demonstrated by determining the endogenous P4 content in different undiluted saliva samples with highly variable endogenous contents of the target hormone. The obtained results were in good agreement with those provided by the conventional ELISA methodology and with the contents reported in the literature for samples with similar characteristics. This validated the combined device for the reliable and minimally invasive determination of the target hormone involving a very simple protocol and taking only 45 min.

Abstract
This review aims to provide a brief historical overview of the feto-maternal immunological relationship, which profoundly influences the outcome of pregnancy. The initial question posed in the 1950s by Medawar [Symp Soc Exp Biol. 1953; 7: 320-338] was based on the assumption that the maternal immune system recognizes the fetus as an allograft. Indeed, based on the association between HLA-matching and spontaneous miscarriage, it became obvious that immunological recognition of pregnancy is required for a successful gestation. The restricted expression of polymorphic HLA antigens on the trophoblast, together with the presence of nonpolymorphic MHC products, excludes recognition by both T and NK cells of trophoblast-presented antigens; however, γδ T cells, which constitute the majority of decidual T cells, are likely candidates. Indeed, a high number of activated, progesterone receptor-expressing γδ T cells are present in the peripheral blood of healthy pregnant women and, in the presence of progesterone, these cells secrete an immunomodulatory protein called progesterone-induced blocking factor (PIBF). As early as in the peri-implantation period, the embryo communicates with the maternal immune system via PIBF containing extracellular vesicles. PIBF contributes to the dominance of Th2-type reactivity which characterizes normal pregnancy by inducing increased production of Th2 cytokines. The high expression of this molecule in the decidua might be one of the reasons for the low cytotoxic activity of decidual NK cells.

Abstract
A 33-year-old woman presented with recurring pruritic, erythematous papules around the mouth and on the hands, of 1.5 years' duration. These flares typically began several days before her menstrual cycle and persisted for approximately 1 week. Physical examination revealed urticarial plaques on the neck. Due to the nature of the eruption, which corresponded with her menstrual cycle, a diagnosis of autoimmune progesterone urticaria was considered and workup pursued.

Abstract
The in vitro expansion is detrimental to therapeutic applications of amniotic epithelial cells (AEC), an emerging source of fetal stem cells. This study provides molecular evidences of progesterone (P4) role in preventing epithelial-mesenchymal transition (EMT) in ovine AEC (oAEC). oAEC amplified under standard conditions spontaneously acquired mesenchymal properties through the up-regulation of EMT-transcription factors. P4 supplementation prevented phenotype shift by inhibiting the EMT-inducing mechanism such as the autocrine production of TGF-β and the activation of intracellular-related signaling. The effect of P4 still persisted for one passage after steroid removal from culture as well as steroid supplementation promptly reversed mesenchymal phenotype in oAEC which have experienced EMT during amplification. Furthermore, P4 promoted an acute up-regulation of pluripotent genes whereas enhanced basal and LPS-induced oAEC anti-inflammatory response with an increase in anti-inflammatory and a decrease in pro-inflammatory cytokines expression. Altogether, these results indicate that P4 supplementation is crucial to preserve epithelial phenotype and to enhance biological properties in expanded oAEC. Therefore, an innovative cultural approach is proposed in order to improve therapeutic potential of this promising source of epithelial stem cells.

Abstract
Avidin is well known for its high affinity to biotin and has been found in many egg-laying vertebrate species. However, little is known about avidin in invertebrate species to date. Here we clearly showed the presence of two avidin genes, Bjavidin1 and Bjavidin2, in the amphioxus Branchiostoma japonicum, the first ones in non-vertebrate animals. We also showed that the expression of both Bjavidin1 and Bjavidin2 were inducible by progesterone, LTA and LPS. Moreover, we demonstrated for the first time that in addition to biotin-binding, the recombinant proteins rBjAVIDIN1 and rBjAVIDIN2 were not only able to interact with Gram-positive and negative bacteria as well as their conserved surface components LTA and LPS but also to enhance phagocytosis of bacteria by macrophages, suggesting that BjAVIDIN1 and BjAVIDIN2 both function as pattern recognition receptors and opsonins. It is thus clear that avidin may play a dual role in biotin-binding and immune response.

Abstract
The specific factors which regulate differentiation and maturation of dendritic cells in bovine pregnancy remain unclear. We evaluated the influence of physiologically relevant in vitro treatments of progesterone (PG) and estradiol (E2) observed in late pregnancy on the differentiation and maturation of CD14+ monocyte-derived dendritic cell (moDC) from non-pregnant, lactating dairy cows (n=7). We found that moDC differentiated in the presence of both E2 and PG had impaired E. coli-induced phenotypic maturation, specifically a significant reduction in CD80 and MHC II expression. Contrary to our previous work characterizing moDC from late gestating dairy cattle, we did not observe an increase in CD14 expression relative to the untreated control; this increase was only observed in the current data in the dexamethasone-treated moDC. The moDC treated with a combination of both E2 and PG had significantly greater upregulation of anti-inflammatory cytokine IL-10 relative to the untreated control, but TNFα production was not suppressed; only dexamethasone-treated moDC showed abrogated TNFα production. These data suggest moDC may be regulated by E2 and PG to hinder phenotypic maturation and regulate inflammatory responses. Pregnancy-associated hormone profiles appear to be involved in the generation of maternal immune tolerance in pregnancy. These hormone-facilitated changes to moDC in pregnancy may also impede optimal immune responses to both invading pathogens and routine vaccinations administered in late gestation through limited antigen presentation and increased anti-inflammatory cytokine production. These results provide insight into maternal immune modulation and elucidate potential immune changes necessary to facilitate bovine pregnancy.

Abstract
Sex hormones seem to play an important role as modulators of the autoimmune disease onset/perpetuation. Generally, steroid hormones are implicated in the immune response, with estrogens as enhancers at least of the humoral immunity and androgens and progesterone (and glucocorticoids) as natural immunosuppressors. Synovial fluid levels (SF) of proinflammatory estrogens relative to androgens are significantly elevated in both male and female rheumatoid arthritis (RA) patients, as compared to controls, which is most probably due to increase of local enzymatic aromatase activity. Serum levels of estrogens have been found altered in RA patients, particularly estradiol in man. Thus, available steroid prehormones are rapidly converted to proinflammatory estrogens in the synovial tissue in the presence of inflammatory cytokines (i.e., TNFa, IL-1, IL-6). The increased estrogen concentrations observed in RA SF of both sexes are characterized mainly by the hydroxylated forms, in particular, 16a-hydroxyestrone, showing a mitogenic tumor growth stimulating role. Altered serum hydroxylated estrogens have been found also in serum of systemic lupus erythematosus (SLE) patients. As a matter of fact, our recent studies indicate that 17-b estradiol (E2) clearly enhanced the expression of markers of cell growth and proliferation, whereas testosterone (T) induced an increase of markers indicating DNA damage and apoptosis. In particular, our data further shows that the enhancing role of estrogens on immune/inflammatory response is exerted by activating the NFkB complex pathway. In conclusion, locally increased estrogens (i.e., synovial tissue in RA or skin in SLE) might exert activating effects on cell proliferation, including macrophages and fibroblasts, suggesting new roles for estrogens in autoimmunity.

Abstract
During pubertal development, an animal's response to stress changes and sexual differentiation of the brain and behavior continue. We discovered that particular stressors, such as shipping from suppliers or an immune challenge with lipopolysaccharide, during the prolonged pubertal period of female mice result in long-term changes in behavioral responsiveness of the brain to estradiol assessed in adulthood. All behaviors influenced by estradiol and/or progesterone that we have studied are compromised by a stressor during pubertal development. Depending on the behavior, immune challenge or shipping from suppliers during pubertal development decreases, eliminates, or even reverses the effects of estradiol. Shipping during this period causes changes in the number of estrogen receptor-immunoreactive cells in key brain areas suggesting one cellular mechanism for this remodeling of the brain's response to hormones. We suggest that particular adverse experiences in girls may cause long-term alterations in the brain's response to estradiol and/or progesterone via activation of the immune system. This in turn could lead to an alteration in any aspect of mental health that is influenced by estradiol.

Abstract
In the recent years according to WHO, genital chlamydia is the mos't common sexually transmitted infection. Chlamydia Trachomatis is an intracellular parasite which target are the tubular epithelial cells of the urethra, endocervix, endometrium, endosalpinx, conjunctiva, synovial lining of the joints, Glisson's capsule of the liver Our study, as well as some international researches, shows that in the cases of genital chlamydia there are changes in the ovarian hormones (estradiol and progesterone), their impact on the immune system and their importance for the development and the complications of the infection with Chlamydia trachomatis. The physiological level of the steroid hormones in its turn contributes for the normalization of the local immunity and reduces the possibility of recurrences.

Abstract
Neuroinflammation in the central nervous system is triggered by toxic stimuli or degenerative events, orchestrates the interplay of brain-intrinsic immune cells and neighboring neural cells, and sequentially allows leukocyte extravasation from the periphery into the brain parenchyma. During the inflammatory cascade, immune-competent cells become activated and secrete a plethora of cytokines and chemokines which form a local inflammatory signaling network important for warding off harmful stimuli to the host but are likewise necessary to preserve damaged brain tissue. Inflammatory responses are initiated by extra- and intra-cellular pathogen and danger-associated receptors. These signals are processed by multi-protein complexes termed inflammasomes which trigger the production of biologically active interleukins-1 and 18 after the cleavage of caspase-1. Estrogens and progesterone are neuroprotective and anti-inflammatory in diverse disease models of the brain in particular under acute inflammatory conditions such as stroke and traumatic brain injury. Both steroids are able to attenuate pro-inflammatory cytokine activity. Recent literature and our own studies provide convincing evidence that the anti-inflammatory potency of these steroids result from a complex interaction with the inflammasome activation and their up-stream regulatory network of miRNAs in brain-intrinsic innate immune cells. This article examines steroid-inflammasome interactions in the brain during brain injury and illuminates the importance of regulation initial upstream events during neuroinflammation. This article is part of a Special Issue entitled 'Steroid Perspectives'.

Abstract
Similarities between the pathologic progression of cancer and the physiologic process of placentation (eg, proliferation, invasion, and local/systemic tolerance) have been recognized for many years. Sex hormones such as human chorionic gonadotropin, estrogens, progesterone, and others contribute to induction of immunologic tolerance at the beginning of gestation. Sex hormones have been shown to play contributory roles in the growth of cancers such as breast cancer, prostrate cancer, endometrial cancer, and ovarian cancer, but their involvement as putative mediators of the immunologic escape of cancer is still being elucidated. Herein, we compare the emerging mechanism by which sex hormones modulate systemic immunity in pregnancy and their potentially similar role in cancer. To do this, we conducted a PubMed search using combinations of the following keywords: "immune regulation," "sex hormones," "pregnancy," "melanoma," and "cancer." We did not limit our search to specific publication dates. Mimicking the maternal immune response to pregnancy, especially in late gestation, might aid in design of better therapies to reconstitute endogenous antitumor immunity and improve survival.

Abstract
During early pregnancy, the human uterus undergoes profound tissue remodeling characterized by leukocyte invasion and production of proinflammatory cytokines, followed by tissue repair and tolerance maintenance induction. Vasoactive intestinal peptide (VIP) is produced by trophoblast cells and modulates the maternal immune response toward a tolerogenic profile. Here, we evaluated the contribution of the VIP/VPAC to endometrial renewal, inducing decidualization and the recruitment of induced regulatory T cells (iTregs) that accompany the implantation period. For that purpose, we used an in vitro model of decidualization with a human endometrial stromal cell line (HESC) stimulated with progesterone (P4) and lipopolysaccharide (LPS) simulating the inflammatory response during implantation and human iTregs (CD4(+)CD25(+)FOXP3(+)) differentiated from naïve T cells obtained from peripheral blood mononuclear cells of fertile women. We observed that VIP and its receptor VPAC1 are constitutively expressed in HESCs and that P4 increased VIP expression. Moreover, in HESC VIP induced expression of RANTES (CCL5), one of the main chemokines involved in T cell recruitment, and this effect is enhanced by the presence of P4 and LPS. Finally, assays of the migration of iTregs toward conditioned media from HESCs revealed that endogenous VIP production induced by P4 and LPS and RANTES production were involved, as anti-RANTES neutralizing Ab or VIP antagonist prevented their migration. We conclude that VIP may have an active role in the decidualization process, thus contributing to recruitment of iTregs toward endometrial stromal cells by increasing RANTES expression in a P4-dependent manner.

Abstract
This study explores the role of ovarian hormones in the phenotypic shaping of peripheral T-cell pool over the reproductive lifespan of rats. For this purpose, 2-month-old prepubertally ovariectomised (Ox) rats, showing oestrogen and progesterone deficiency, and 11-month-old Ox rats, exhibiting only progesterone deficiency, were examined for thymus output, and cellularity and composition of major TCRαβ+ peripheral blood lymphocyte (PBL) and splenocyte subsets. Although ovariectomy increased thymic output in both 2- and 11-month-old rats, the count of both CD4+ and CD8+ PBLs and splenocytes increased only in the former. In the blood and spleen of 11-month-old Ox rats only the count of CD8+ cells increased. Although ovariectomy affected the total CD4+ count in none of the examined compartments from the 11-month-old rats, it increased CD4+FoxP3+ PBL and splenocyte relative proportions over those in the age-matched controls. The age-related differences in the cellularity and the major subset composition in Ox rats were linked to the differences in the ovarian steroid hormone levels registered in 2- and 11-month-old rats. The administration of progesterone to Ox rats during the seven days before the sacrificing confirmed contribution of this hormone deficiency to the ovariectomy-induced changes in the TCRαβ+ PBL and splenocyte pool from 11-month-old rats. The expansion of the CD8+ splenocyte subset in the 11-month-old Ox rats reflected increases in cellularity of memory and, particularly, naïve cells. This was due to greater thymic output of CD8+ cells and homeostatic proliferation than apoptosis in 11-month-old Ox rats when compared with age-matched sham-Ox control rats. The homeostatic changes within CD8+ splenocyte pool from 11-month-old Ox rats, most likely, reflected the enhanced splenic IL-7 and TGF-β mRNA expression. Overall, in adult female rats, circulating oestrogen and progesterone provide maintenance of T-cell counts, a diversity of T-cell repertoire, and the main T-cell subset composition in the periphery. Progesterone deficiency affects mainly the CD8+ lymphocyte compartment through increasing thymic CD8+ cell export and upsetting homeostatic regulation within the CD8+ splenocyte pool. These alterations were reversible through progesterone supplementation.

Abstract
Steroid hormones, such as progesterone, are able to modify immunity and influence disease outcome. Dendritic cells (DCs) drive potent immune responses, express receptors for steroid hormones, and may be a primary target of steroid hormone actions during infection of the genital tract, including uterine tissue. Here, we report that progesterone limited DC-associated activation marker expression and inhibited cytokine secretion by uterine DCs, which was associated with changes in signal transducer and activator of transcription 1 (STAT1) activity. We also found that DCs from mice at stages with higher progesterone concentrations (diestrus, metaestrus) were more sensitive to progesterone than those in stages with lower progesterone concentrations (proestrus, estrus), both in vitro and in vivo. This difference correlated with the levels of progesterone receptor expressed by DCs. These data suggest that progesterone regulates DC function and could contribute to the susceptibility of females to uterine and other genital tract infections at selected time periods throughout the life cycle.

Abstract
Bacterial infection shortly after mating interferes with establishment of pregnancy. Injection of peptidoglycan-polysaccharide (PG-PS), a component of gram-positive bacteria, into sheep on day 5 after mating reduces pregnancy rate. Experiments were designed to evaluate the acute-phase response (APR) in ewes to injection of PG-PS on day 5 after mating (day 0). Catheters were inserted into the jugular and posterior vena cava on day 4. On day 5, ewes were challenged with saline or 30 microg/kg body weight (BW) PG-PS (Exp 1) or 60 microg/kg BW PG-PS (Exp 2). Blood samples were collected every 15 min for 6 h (Exp 1) and every 15 min for 2 h, hourly for 12 h, and at 24, 36, and 48 h (Exp 2). Body temperature and clinical signs of infection were monitored in Exp 2. Plasma was assayed for concentrations of a pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-alpha); 2 APR proteins, serum amyloid A (SAA) and haptoglobin (Hp); and progesterone (P(4)). Ewes injected with 60 microg/kg BW PG-PS exhibited fever, vaginal discharge, loss of appetite, and lethargy. After challenge with either 30 microg/kg or 60 microg/kg BW PG-PS, TNF-alpha increased in the posterior vena cava. Concentrations of SAA and Hp in the jugular increased after challenge with 60 microg/kg BW PG-PS. Only half (5/10) of the ewes treated with 60 microg/kg BW PG-PS had ultrasonically visible embryos, and none of them had functional corpora lutea (CL) (<1 ng/mL of P(4)) on day 21. On the other hand, 8/9 (88.9%) control ewes had visible embryos and all had functional CL on day 21. Using logistic regression, pregnancy on day 21 was predicted to depend on concentrations of TNF-alpha and Hp on day 5 and concentration of P(4) on day 14. In summary, injection of PG-PS on day 5 after mating resulted in fever; increased concentrations of TNF-alpha, Hp, and SAA on the day of and the day after the PG-PS challenge; and decreased concentrations of P(4) on days 14 and 21. These factors were related to failure to establish pregnancy.

Abstract
The aim of the present experiments was to demonstrate the release of insulin-like growth factor-I (IGF-I) by human granulosa cells, and to examine the role of growth hormone (GH), oxytocin, steroids and cAMP-dependent intracellular mechanism in its control. A significant accumulation of IGF-I in a serum-supplemented medium in which the human granulosa cells were cultured for 4 days was observed. The concentration of IGF-I in the medium was particularly high at 3 and 4 days of culture. The addition of GH (1-10,000 ng/ml) to the medium increased IGF-I secretion by the cells. A higher GH dose (100,000 ng/ml) was inhibitory. Oxytocin stimulated IGF-I release at doses of 10-10,000 ng/ml. Dibutyryl-cAMP, isobutyl-methyl-xanthine (inhibitor of cAMP catabolism) or forskolin (stimulator of cAMP production) inhibited IGF-I output at these doses. Additions of progesterone (1-1,000 ng/ml) did not affect IGF-I release, whilst adrostenedione and estradiol were stimulatory at doses of 1, 10, 100, 1,000 ng/ml and 10, 100 and 1,000 ng/ml respectively. Testosterone inhibited IGF-I at a dose of 1,000 ng/ml but not at lower doses (1, 10 or 100 ng/ml). Blockade of estradiol (but not of testosterone) in the medium by specific antisera (1 or 10%) significantly reduced IGF-I output. The same effect was observed with an antiserum to progesterone when added at 0.1%, whilst higher doses (1 or 10%) stimulated IGF-I secretion. The present observations demonstrate the involvement of peptide, steroid hormones and cAMP in the regulation of IGF-I secretion by luteinized human granulosa cells. In particular, both GH and oxytocin are stimulators of IGF-I release. Estradiol and androstenedione, but not testosterone, may also be stimulators of IGF-I output. The involvement of progesterone in this process can also not be excluded. A cAMP-dependent intracellular mechanism appears to play an inhibitory role in the regulation of IGF-I secretion by luteinized human granulosa cells.

Abstract
We report the case of a 39-year-old Hungarian woman who cyclically experienced painful, erythematous, patchy skin lesions on her face and chest. Because of her irregular menses and hysterectomy performed later on to manage endometriosis, it was difficult to link her symptoms to the menstrual cycle. But on the basis of the cyclic nature of the rash and the previous negative results - acne vulgaris, psoriasis, atopic dermatitis, lichen planus, systemic lupus erythematosus and infections were ruled out - autoimmune progesterone dermatitis was suspected. As progesterone is not available in aqueous solution for intradermal allergen test in Hungary, we performed progesterone provocation vaginally. The patient developed the usual skin lesions to vaginal progesterone exposure, which confirmed the diagnosis. The patient became symptom free to gonadotropine-analogue treatment and remained so even after the cessation of the therapy after 6 months. To our knowledge, this is the first case in the medical literature, in which autoimmune progesterone dermatitis was proved by vaginal progesterone provocation.

Abstract
To develop a reliable approach to pregnancy diagnosis in sables based on noninvasive methods of hormonal status assessment, the concentrations of immunoreactive compounds (IRC) binding with antibodies to progesterone have been measured in the feces of females at different stages of the reproductive cycle. The results show that this concentration is higher in truly pregnant than in mated but nonreproducing females. An increase in the IRC concentration relative to its individual baseline level may be regarded as a reliable indication of true pregnancy.

Abstract
Progesterone induced dermatitis is a rare disorder. It typically occurs in females due to an autoimmune phenomenon to endogenous progesterone production, but can also be caused by exogenous intake of a synthetic progestin. Here in, we present a case of autoimmune progesterone anaphylaxis (AIPA) observed in an adolescent female. The patient is an 18-year-old Caucasian female with no significant past medical history and no prior exogenous hormone use, who presented to her primary care physician complaining of cyclic skin eruptions with dyspnea, cough and respiratory distress. She noted that her symptoms occurred monthly, just prior to her menses. An intradermal skin test using 0.1 cml of progesterone was performed. The patient developed a 15 mm wheal after 15 minutes, confirming the diagnosis of AIPA. The patient was started on a continuous regimen of an oral conjugated estrogen (0.625 mg). The skin eruptions and respiratory symptoms have not returned since the initiation of this therapy. Autoimmune progesterone dermatitis manifests via the occurrence of cyclic skin eruptions. Women with the disorder commonly present with dermatologic lesions in the luteal phase of the menstrual cycle, if there are any other organ involvement in addition to skin (e.g. lung, GI) the reaction should be called as autoimmune progesterone anaphylaxis. Diagnosis of AIPA is confirmed by performing a skin allergen test using progesterone.

Abstract
Any pruritus occurring in pregnant women may represent a sensorial manifestation unrelated to pregnancy, but it may represent the consequence of a pregnancy-specific dermatosis. This latter group encompass pruritus gravidarum with or without intrahepatic cholestasis, pemphigoid gestationis, polymorphic eruption of pregnancy, prurigo gestationis, acute folliculitis of pregnancy, impetigo herpetiformis and the progesterone auto-immune dermatitis. Fetal risk of morbidity is recognized for pruritus gravidarum with intrahepatic cholestasis, pemphigoid gestationis and impetigo herpetiformis.

Abstract
We evaluated the role of estradiol and progesterone in allergic lung inflammation. Rats were ovariectomized (Ovx) and, 7 days later, were sensitized with ovalbumin (OA) and challenged after 2 wk with inhaled OA; experiments were performed 1 day thereafter. Ovx-allergic rats showed reduced cell recruitment into the bronchoalveolar lavage (BAL) fluid relative to sham-Ovx allergic rats, as was observed in intact allergic rats treated with ICI-182,780. Estradiol increased the number of cells in the BAL of Ovx-allergic rats, whereas progesterone induced an additional reduction. Cells of BAL and bone marrow (BM) of Ovx-allergic rats released elevated amounts of IL-10 and reduced IL-1beta and TNF-alpha. BM cells of Ovx-allergic rats released increased amounts of IL-10 and lower amounts of IL-4. Estradiol treatment of Ovx-allergic rats decreased the release of IL-10 but increased that of IL-4 by BM cells. Estradiol also caused an increased release of IL-1beta and TNF-alpha by BAL cells. Progesterone significantly increased the release of IL-10, IL-1beta, and TNF-alpha by BAL cells and augmented that of IL-4 by BM cells. Degranulation of bronchial mast cells from Ovx rats was reduced after in vitro challenge, an effect reverted by estradiol but not by progesterone. We suggest that the serum estradiol-to-progesterone ratio might drive cellular recruitment, modulating the pulmonary allergy and profile of release of anti-inflammatory or inflammatory cytokines. The existence of such dual hormonal effects suggests that the hormone therapy of asthmatic postmenopausal women and of those suffering of premenstrual asthma should take into account the possibility of worsening the pulmonary conditions.

Abstract
The development of a simultaneous multianalyte immunoassay for the detection of progesterone and human chorionic gonadotropin (hCG) in serum is described. In this simultaneous multianalyte assay, two different enzymes, viz. horse radish peroxidase (HRP) and alkaline phosphatase (ALP), were used as markers. To the simultaneous immobilized progesterone and hCG antibody microwells, 50 microL of different concentrations of combined standards or serum samples was added in duplicate and then 100 microL of combined conjugate reagent, composed of 17-alpha-OH-P-ALP and hCG-biotin was added to all the wells and incubated for 1h at 37 degrees C. After incubation, the contents of the wells were decanted and washed thoroughly with running tap water. After washing, 100 microL alkaline phosphatase substrate along with streptavidin-horseradish peroxidase was added to all the wells and incubated for 0.5 h at 37 degrees C. After incubation, the developed color was measured at 405 nm. The absorbency at this stage provides the result for the progesterone assay. The contents of the wells were decanted and washed. In the next step, 100 microL of tetramethylbenzidene/H2O2 reagent was added to all the wells. After 15 min of incubation, 100 microL of 0.5 M H2SO4 was added to all the wells and the color was read at 450 nm. The absorbency at this stage provides the result for the hCG assay. Sensitivity of the progesterone and hCG assays were 0.118 ng/ml and 0.124 IU/ml respectively. Intra- and inter assay percentage coefficients of variation ranged from 1.8 to 7.1 and 9.1 to 11.5 for progesterone and from 2.1 to 10.4 and 7.2 to 11.3 for hCG. There was good correlation between the discrete and the simultaneous assays. For progesterone assay, R2 was 0.99 and for hCG R2 was also 0.99. The developed dual assay for progesterone and hCG may be useful for the diagnosis of abnormal pregnancies such as miscarriages and ectopic pregnancies.

Abstract
Little is known about concurrent expression of cervical cytokines and their regulation by sex hormones during primary or recurrent chlamydial infections in humans. Cytokine (interleukin-1beta [IL-1beta], IL-6, IL-10, interferon-gamma [IFN-gamma], and tumor necrosis factor-alpha [TNF-alpha]) concentrations in cervical washes and serum samples, along with levels of beta-estradiol and progesterone in women with primary or recurrent chlamydial infections and healthy controls, were measured by ELISA. Women with recurrent infections had significantly higher levels of IFN-gamma in cervical washes than did women with primary infections. Significant negative correlation was found between IL-1beta and progesterone levels during recurrent infections. Beta-estradiol levels in women with primary infections showed significant negative correlations with cervical concentrations of IL-10, IL-1beta, and IL-6. Our study suggests that Chlamydia trachomatis infection in the female genital tract may be regulated by both the synergistic actions of the cytokines and the sex hormones beta-estradiol and progesterone.

Abstract
PROBLEM Several studies indicate that RANTES (regulated on activation, normal T cell expressed and secreted) is able to downregulate T-cell responses which suggest it might be relevant for fetal tolerance induction. However, the role of RANTES in pregnancy had not been established. Here we investigate RANTES regulation during early pregnancy and potential failures leading to losses of pregnancies. METHOD OF STUDY RANTES and progesterone levels were determined in sera and feto-placental units from high resorption rate CBA/JxDBA/2 pregnant females and compared with CBA/JxBALB/c normal pregnant mice. RANTES in vitro modulation was also studied in nulliparous, primiparous and multiparous CBA/J and BALB/c cells in response to paternal alloantigen and progesterone stimulation. RESULTS Nulliparous CBA/J females were quantitatively deficient in RANTES sera levels, whereas pregnancies with male BALB/c or DBA/2 increased its production. However, feto-placental units from CBA/J females are high producers of progesterone and RANTES. CONCLUSION These data suggest that the beneficial effect of RANTES on feto-maternal interface requires an optimal concentration range and might be modulated by progesterone, hence exacerbated placental expression could be associated with high resorption rate.

Abstract
The crystal structures of the Fab' fragment of the anti-progesterone monoclonal antibody DB3 and its complexes with steroid haptens have shown that the D-JH junctional residue TrpH100 is a key contributor to binding site interactions with ligands. The indole group of TrpH100 also undergoes a significant conformational change between the bound and unliganded states, effectively opening and closing the combining site pocket. In order to explore the effect of substitutions at this position on steroid recognition, we have carried out mutagenesis on a construct encoding a three-domain single-chain fragment (VH/K) of DB3 expressed in Escherichia coli. TrpH100 was replaced by 13 different amino acids or deleted, and the functional and antigenic properties of the mutated fragments were analyzed. Most substitutions, including small, hydrophobic, hydrophilic, neutral, and negatively charged side chains, were reduced or abolished binding to free progesterone, although binding to progesterone-BSA was partially retained. The reduction in antigen binding was paralleled by alteration of the idiotype associated with the DB3 combining site. In contrast, the replacement of TrpH100 by Arg produced a mutant that retained wild-type antibody affinity and idiotype, but with altered specificity. Significant changes in this mutant included increased relative affinities of 10(4)-fold for progesterone-3-carboxymethyloxime and 10-fold for aetiocholanolone. Our results demonstrate an essential role for the junctional residue H100 in determining steroid-binding specificity and combining site idiotype and show that these properties can be changed by a single amino acid substitution at this position.

Abstract
Progesterone in saliva was monitored using a new method called magnetic particle-based immuno supported liquid membrane assay (m-ISLMA) in a sequential injection (SI) setup, allowing automatic sample cleanup, analyte enrichment, and detection in a single analysis unit. Progesterone (Ag) diffuses from a continuous flowing sample - the donor - into a supported organic liquid membrane (SLM), based on analyte partitioning (solubility) between the aqueous donor and the organic phase. The Ag is re-extracted from the SLM into a second stagnant aqueous acceptor, containing antibodies (Ab) immobilized on magnetic beads, held at the bottom of the acceptor by a magnet. Due to the formation of strong Ag-Ab-bead complexes and a large excess of Ab-beads, the Ag is accumulated and selectively enriched in the acceptor. The extracted progesterone was quantified by injecting into the acceptor a horseradish peroxidase (HRP) labeled analyte tracer, the substrate (luminol, H(2)O(2), and p-iodophenol), and finally detection of the generated chemiluminescence by a photomultiplier tube. After optimization of experimental parameters (e.g., sample flow rate, extraction time, type of organic solvent and antibody-bead concentration in the acceptor), a detection limit of 8.50+/-0.17 fgL(-1) and a dynamic range between 35 fgL(-1) and 10 pgL(-1) was reached. The progesterone level of saliva for three subjects (women in different period of ovarian cycle) was investigated, and the corresponding progesterone concentrations detected with m-ISLMA coincided well with the expected values.

Abstract
BACKGROUND Estrogen and progesterone have been associated in women with symptoms that include asthma, migraine, dermatitis and pain. OBJECTIVE We suggest a connection between symptoms associated with hormone changes to a hormone antibody response. METHODS For IgG, IgM and IgE antibodies to progesterone, blood samples were obtained from 288 healthy control subjects by a commercial lab in California. Blood from 270 patients in Texas with changes in symptoms associated with menstrual cycles was examined. For IgE antibodies to both progesterone and estrogen, blood samples were obtained from an additional 32 healthy control subjects who had no symptoms related to menses and from 98 patients with symptoms associated with menstrual cycles. The symptoms were asthma, migraines and joint pain. RESULTS At 2 S.D. above the mean values of control subjects, a significant number of patients show high levels of IgG, IgM and IgE antibodies to progesterone and estrogen. CONCLUSIONS This paper describes evidence of antibodies to the hormones estrogen and progesterone. Progesterone, estrogen and their metabolites, after binding to human tissue proteins, such as albumin or globulin, may act as antigens and promote Type 2 helper cell development, thereby regulating antibody synthesis and allergy. This leads to the possibility of treating a wide variety of disorders by determining hormone allergy and initiating desensitization. Two obvious applications for determination and treatment of hormone allergies are pre-menstrual asthma and menstrual migraines.

Abstract
BACKGROUND Progesterone-induced dermatitis is a rare disorder. It typically occurs in females due to an autoimmune phenomenon to endogenous progesterone production, but can also be caused by exogenous intake of a synthetic progestin. Here, we present a case of autoimmune progesterone dermatitis (AIPD) seen in an adolescent female. CASE The patient is a 15-year-old Caucasian female with no significant past medical history and no prior exogenous hormone use, who presented to her primary care physician complaining of cyclic skin eruptions. She noted that her dermatologic symptoms occurred monthly, just prior to her menses. An intradermal skin test using 0.1 cc of progesterone was performed. The patient immediately developed a wheal, confirming the diagnosis of AIPD. The patient was begun on a continuous regimen of an oral contraceptive pill with 30 micrograms of ethinyl estradiol and 0.15 mg of levonorgestrel. The skin eruptions have not returned since the initiation of this therapy. CONCLUSION Autoimmune progesterone dermatitis manifests via the occurrence of cyclic skin eruptions. Women with the disorder commonly present with dermatologic lesions in the luteal phase of the menstrual cycle. Diagnosis of AIPD is confirmed by performing a skin allergen test using progesterone. Due to its rarity, AIPD should be considered a diagnosis of exclusion. In cases believed to be due to an endogenous production of progesterone, several methods of therapy have been attempted. The ultimate goal of therapy is the suppression of ovulation, which will prevent endogenous hormone production as progesterone is only produced in ovulatory cycles. Currently, the first-line choice of therapy is a combination oral contraceptive. If this treatment is ineffective, patients have been treated with danazol, gonadotropin releasing hormone analogs, tamoxifen, and oophorectomy with varying success.

Abstract
Autoimmune progesterone dermatitis is a rare clinical condition in which patients display hypersensitivity to endogenous progesterone. It manifests as a cyclical cutaneous eruption that flares during the luteal phase of the menstrual cycle, when progesterone levels peak, and resolves partially or completely a few days after menses. Its cutaneous manifestations are variable and include urticaria, eczematous eruptions, vesiculopustular eruptions, fixed drug eruptions, stomatitis, erythema multiforme, and anaphylaxis. Autoimmune progesterone dermatitis has been diagnosed previously with intradermal skin testing or intramuscular progesterone challenge. Treatment of progesterone hypersensitivity generally consists of ovulation inhibition with pharmaceutical agents or oophorectomy; other therapies (eg, thalidomide) have also been used with success. We report a case of cyclical erythema multiforme (EM) induced by hypersensitivity to endogenous progesterone in a patient with a history of past oral contraceptive use. After herpes simplex virus was ruled out as an etiologic factor, a diagnosis of progesterone hypersensitivity was confirmed with intradermal skin testing. Results of subsequent patch testing with various progesterone derivatives were negative. The EM outbreaks were suppressed temporarily by continuous administration of Loestrin (ethinyl estradiol plus norethindrone), which also increased the responsiveness of the outbreaks to prednisone tapers.

Abstract
Progesterone given after traumatic brain injury (TBI) has been shown to reduce the initial cytotoxic surge of inflammatory factors. We used Western blot techniques to analyze how progesterone might affect three inflammation-related factors common to TBI: complement factor C3 (C3), glial fibrillary acidic protein (GFAP), and nuclear factor kappa beta (NFkappaB). One hour after bilateral injury to the medial frontal cortex, adult male rats were given injections of progesterone (16 mg/kg) for 2 days. Brains were harvested 48 h post-TBI, proteins were extracted from samples, each of which contained tissue from both the contused and peri-contused areas, then measured by Western blot densitometry. Complete C3, GFAP, and NFkappaB p65 were increased in all injured animals. However, in animals given progesterone post-TBI, NFkappaB p65 and the inflammatory metabolites of C3 (9 kDa and 75 kDa) were decreased in comparison to vehicle-treated animals. Measures of NFkappaB p50 showed no change after injury or progesterone treatment, and progesterone did not alter the expression of GFAP. The therapeutic benefit of post-TBI progesterone administration may be due to its salutary effect on inflammatory proteins known to increase immune cell invasion and cerebral edema.

Abstract
The objective of the study was to develop and validate a simple, reliable, and highly sensitive radioimmunoassay (RIA) for progesterone determination in mithun (Bos frontalis) plasma. The RIA was carried out in 20 microL unextracted mithun plasma. The progesterone standards ranging from 2 to 500pg/20 microL/tube were prepared in charcoal-treated hormone-free plasma. The sensitivity of the RIA procedure was 2 pg progesterone/20 microL/tube, which corresponds to 0.1 ng/mL; the 50 percent relative binding sensitivity was seen at 32pg/20 microL/tube. Plasma volumes for the RIA, viz. 10 and 20 microL, did not influence the shape of standard curve, even though a slight drop in the counts was seen with higher plasma volumes. For the biological validation of the assay, three cyclic, three in early pregnancy, and two in late pregnancy mithuns were used. Blood samples collected at weekly intervals for 42 days, from all animals, were assayed for plasma progesterone. The peak level of progesterone was registered at day 14 (day 21 of sampling) of the estrous cycle and the lowest at estrus; the progesterone concentrations increased and decreased gradually as sampling time advanced, in early and late pregnancy, respectively, which confirm the biological validation of the RIA. The RIA avoids the troublesome and laborious plasma extraction procedures. In conclusion, the RIA developed for progesterone determination in mithun blood plasma is sufficiently reliable, simple, and sensitive enough to estimate progesterone in all physiological variations in mithun.

Abstract
An electrochemical biosensor for progesterone in cow's milk was developed and used in a competitive immunoassay by Hart et al. (1977, Studies towards a disposable screenprinted amperometric biosensor for progesterone, Biosens. Bioelectron. 12, 1113-1121). The sensor was fabricated by depositing anti-progesterone monoclonal antibody (mAb) onto screen-printed carbon electrodes (SPCEs) which were coated with rabbit anti-sheep IgG (rIgG). This sensor was operated following the steps of competitive binding between sample and conjugate (alkaline-phosphatase-labelled progesterone) for the immobilised mAb sites and measurements of an amperometric signal in the presence of p-nitrophenylphosphate using either colorimetric assays or cyclic voltammetry. The hook effect of the progesterone biosensor was found in the concentration range of milk progesterone between 0 and 5 ng/ml when the sensor was fabricated using a loading of 25 ng rIgG per electrode of a diameter of 3 mm and a 1/50 dilution of mAb. A computer model has been developed in this study to simulate the operation of this progesterone biosensor with consideration of the fabrication processes. This paper presents the results of validating the computer model and the model has predicted the hook effect as observed in tests. The model thus reveals that the hook effect is determined by the total number of binding sites available and the rates of labelled and unlabelled progesterone diffusing towards the sensor surface and the binding rates.

Abstract
The aim of this work was to investigate the role of progesterone during Taenia crassiceps cysticercosis, and the immunological mechanisms involved in its effects, by relating progesterone treatment to whole parasite counts, to host humoral and cellular immune response, to the presence or absence of nuclear receptors to sex steroids in splenocytes, and to serum sex steroid levels in infected mice of both genders. Progesterone treatment increased parasite loads two-fold in females and three-fold in males compared with control mice. The expression of the Th2 cytokine profile (IL-4, IL-6 and IL-10) was markedly increased in infected mice of both genders, while progesterone treatment returned this expression to basal levels. However, the Th1 cytokine profile (IFN-gamma and TNF-alpha) was not affected by infection, whilst progesterone treatment increased the expression of both cytokines two-fold compared to uninfected, infected and placebo-treated mice. Testosterone serum levels decreased in infected male mice by 95%, and treatment with progesterone did not affect them. In females, no change in testosterone levels was observed. Progesterone levels increased three-fold only in progesterone-treated infected mice of both sexes, while estradiol levels in female and male progesterone-treated infected mice increased two-fold compared to infected control mice. The infection markedly induced the expression of progesterone receptor (PR) isoforms A and B in splenocytes of infected mice of both genders (five-fold). Metabolism of progesterone to estradiol was demonstrated by the use of the anti-estrogen tamoxifen, which reduced parasite loads 100% in infected mice of both sexes treated with progesterone. These results suggest that progesterone, possibly through its metabolism to estradiol, affects establishment, growth and reproduction of the helminth parasite T. crassiceps.

Abstract
In ribosome display, proteins are linked to their encoding genetic material as protein-ribosome-mRNA complexes. The technology has been applied to the isolation of antibodies and other proteins from large PCR-derived libraries. Here we demonstrate the specificity of eukaryotic ribosome complexes and investigate recovery and display procedures using a single chain version of the anti-progesterone monoclonal antibody DB3. Complexes are formed by deletion of the 3' stop codon in a coupled rabbit reticulocyte system. Using inhibition with different steroid probes, we show that the fine specificity of the combining site expressed as a nascent protein is closely similar to the native monoclonal, indicating correct folding and function while bound to the ribosome. We have demonstrated that the 3' end of the mRNA is blocked by the stalled ribosome and unavailable to primers. Moreover, we show that an in situ RT-PCR recovery procedure, carried out on intact complexes, is more efficient than ribosome disruption and isolation of mRNA followed by RT-PCR. We also explore the Mg(2+) and DTT concentrations and time required for efficient production of complexes. Our findings confirm the effectiveness of the eukaryotic ribosome display system and define conditions for efficient selection of single chain antibodies.

Abstract
Successful pregnancy outcome requires balanced networking of the immune and endocrine system. In addition, numerous sophisticated adaptive mechanisms promote invasion of fetal tissue and facilitate tolerance. This highly sensitive and vulnerable environment may be challenged from either the maternal or the fetal site. In this overview we collect evidence of a functional role of neurotrophins, predominately nerve growth factor (NGF), in pregnancy maintenance. We demonstrate several pathways through which NGF may be involved in maintaining pregnancy and/or--if exaggerated--inducing pregnancy failure. Due to the pleiotropism of NGF, we hypothesize that NGF is mandatory for the success of pregnancy, e.g. via inhibition of paternal MHC II molecule expression on trophoblast cells. This is supported by published evidence on progesterone, the hormone of pregnancy, which maintains local levels of NGF. On the other hand, if levels of NGF are upregulated in response to environmental challenges, e.g. stress, this may result in a threat to pregnancy maintenance due to a skew towards proinflammatory cytokines and increased apoptotic cell death. Hence, we strongly suggest that NGF constitutes a functional link between the nervous, endocrine and immune system translating environmental or endocrine signals during pregnancy into an immunological answer.

Abstract
The biological effects of progesterone are mediated by a 34-kDa protein named the progesterone-induced blocking factor (PIBF). PIBF, synthesized by lymphocytes of healthy pregnant women in the presence of progesterone, inhibits arachidonic acid release as well as NK activity, and modifies the cytokine balance. Within the cell the full-length PIBF is associated with the centrosome, while secretion of shorter forms is induced by activation of the cell. PIBF induces nuclear translocation of STAT6 as well as PKC phosphorylation and exerts a negative effect on STAT4 phosphorylation. The concentration of PIBF in pregnancy urine is related to the positive or negative outcome of pregnancy; furthermore, premature pregnancy termination is predictable by lower than normal pregnancy PIBF values. In vivo data suggest the biological importance of the above findings. Treatment of pregnant Balb/c mice with the antiprogesterone RU 486 results in an increased resorption rate, which is associated with the inability of spleen cells to produce PIBF. High resorption rates induced by progesterone receptor block as well as those due to high NK activity are corrected by simultaneous PIBF treatment.

Abstract
One of the most interesting functions of the placenta is the regulation of the maternal immune response such that the fetal semi-allograft is tolerated during pregnancy. Trophoblasts are presumed to be essential to this phenomenon because they lie at the maternal-fetal interface, where they are in direct contact with cells of the maternal immune system. Trophoblasts do not express classic major histocompatibility complex (MHC) class II molecules. Surprisingly, cytotrophoblasts express more HLA-G, a MHC class Ib molecule, as they invade the uterus. Progesterone plays an important role in postovulatory regulation of the menstrual cycle. If fertilization occurs, progesterone supports implantation of the ovum and maintains the pregnancy. Progesterone has been named the 'hormone of pregnancy', because in preparing the endometrium for embryo implantation and facilitating endometrial development, it is critical to the very survival of a pregnancy. In addition, this key hormone inhibits the rejection of T cell-mediated tissue and also decreases myometrial activity and sensitivity throughout pregnancy. The cellular actions of progesterone are mediated through intracellular progesterone receptors (PRs), which are well studied gene regulators, not express classic major histocompatibility complex. The more used paradigm is relative to the alteration of relationship TH1/TH2, but the complexity of the respective distributions of cytokines at the materno-fetal interface, strongly suggest that, as useful as it certainly was for a while, the Th1/Th2 paradigm must now be considered as an oversimplification. Rather, the existing data point to sequential windows and are suggestive of a system where an extreme complexity is allied to very precise timing and tuning. They also suggest that the materno-fetal relationship is not simply maternal tolerance of a foreign tissue, but a series of intricate mutual cytokine interactions governing selective immune regulation and also control of the adhesion and vascularization processes during this dialogue. However, as shifting the immune response toward the Th2 pattern (IL-4, IL-5, IL-6) may benefit the fetus, whereas development of proinflammatory Th1 cells (secreting IL-2, IFN g, TNF a) may be harmful. Now we are working to open comprise the precise behaviour of NK populations, with the hope of obtaining a diagnostic test of the condition of abortion from 'immunological causes'.

Abstract
Antiestradiol antibody 57-2 binds 17beta-estradiol (E2) with moderately high affinity (K(a) = 5 x 10(8) M(-1)). The structurally related natural estrogens estrone and estriol as well synthetic 17-deoxy-estradiol and 17alpha-estradiol are bound to the antibody with 3.7-4.9 kcal mol(-1) lower binding free energies than E2. Free energy perturbation (FEP) simulations and the molecular mechanics-Poisson-Boltzmann surface area (MM-PBSA) method were applied to investigate the factors responsible for the relatively low cross-reactivity of the antibody with these four steroids, differing from E2 by the substituents of the steroid D-ring. In addition, computational alanine scanning of the binding site residues was carried out with the MM-PBSA method. Both the FEP and MM-PBSA methods reproduced the experimental relative affinities of the five steroids in good agreement with experiment. On the basis of FEP simulations, the number of hydrogen bonds formed between the antibody and steroids, which varied from 0 to 3 in the steroids studied, determined directly the magnitude of the steroid-antibody interaction free energies. One hydrogen bond was calculated to contribute about 3 kcal mol(-1) to the interaction energy. Because the relative binding free energies of estrone (two antibody-steroid hydrogen bonds), estriol (three hydrogen bonds), 17-deoxy-estradiol (no hydrogen bonds), and 17alpha-estradiol (two hydrogen bonds) are close to each other and clearly lower than that of E2 (three hydrogen bonds), the water-steroid interactions lost upon binding to the antibody make an important contribution to the binding free energies. The MM-PBSA calculations showed that the binding of steroids to the antiestradiol antibody is driven by van der Waals interactions, whereas specificity is solely due to electrostatic interactions. In addition, binding of steroids to the antiestradiol antibody 57-2 was compared to the binding to the antiprogesterone antibody DB3 and antitestosterone antibody 3-C4F5, studied earlier with the MM-PBSA method.

Abstract
Women are conferred with greater immunologic and survival benefits compared to men. Female sex steroids contribute to this sexual dimorphism. Furthermore, during human pregnancy when female sex hormones are elevated, neutrophil apoptosis is delayed. This study examines the specific effects of estradiol and progesterone on neutrophil apoptosis and function in healthy adult men and women. We also examined the contribution of these hormones to the persistence and resolution of an inflammatory response. Spontaneous apoptosis was significantly decreased in women compared with men. Physiologic doses of estradiol and progesterone caused a further delay in spontaneous apoptosis in both men and women but did not diminish Fas antibody-induced apoptosis. The delay in apoptosis was mediated at the level of the mitochondria with decreased release of cytochrome c, which may alter caspase cleavage and activity. There were no associated alterations in neutrophil CD11b, but production of reactive oxygen intermediates (ROIs) in women was increased. Thus, female sex hormones mediate delayed neutrophil apoptosis in both sexes and enhance female intracellular production of ROIs. Modulating hormonal responses may be an effective therapeutic tool in combating inflammatory diseases.
