Unprecedented levels of media coverage have helped draw in new fans; 62 countries held TV rights to broadcast the tournament compared with 37 in ; dozens of members of the British media have been in France, far more than were in Canada four years ago. The interest now is above and beyond what we've ever seen.

Who knows how much those numbers would have grown had England made it to the final, or even won their first tournament? It may feel like a missed opportunity in that regard, but with the Olympics and Euros on the horizon the international game looks as if will be in good health. Translating that to the domestic game is the big challenge, but the Football Association says it has been planning for this moment. There was a wave coming and we knew we had to be ready. The problem in the past is that once the euphoria of a major tournament has died down, people return to their normal habits and almost forget that women's football exists on a domestic level.

In , after England finished third, there was an initial bounce in domestic attendances, helped by a summer league that resumed a few weeks after the World Cup. But there is now a wait until the Women's Super League winter season starts in September, by which time the Premier League campaign will have started, occupying the attention of many of the journalists who were out in France. Yet for lots of reasons, women's football is already starting from a better place than four years ago. Despite West Ham skipper Gilly Flaherty saying she still has to buy her own boots, there has never been more money in the game.

Major brands signed up players before the World Cup and even though the team did not fulfil their pledge to win the tournament, there is hope from agents that their clients' interest in the Lionesses will continue. In addition, the WSL is now fully professional and news that the Premier League has moved a step closer to taking over the running of it only adds to the optimism. From an international perspective, the FA has also learned lessons from , when England did not play a home game until a European Championship qualifier almost five months later.

This time, in addition to a friendly game against Germany at Wembley in November, for which more than 30, tickets have already been sold, there are plans for another homecoming game in October. That will increase the amount of people that come to watch. One of the biggest concerns at the FA is about making sure of reaching its lofty attendance targets as part of its four-year 'Gameplan for Growth' strategy. While a visible World Cup campaign will have helped that cause, reaching an average of 2, fans per game in the WSL by looks ambitious.

Women or Men — Who Has a Higher Risk of Heart Attack?

The top-flight average for last season was , which is an improvement on the previous year but down on a peak of 1, achieved in the summer season of A winter switch two years ago saw crowds dip at most clubs bar the top three - Manchester City, Chelsea and Arsenal. For a sport which traditionally attracts families, cold nights at out-of-town stadiums do not help, while clashes with Premier League fixtures present an additional challenge. The FA says its attendance target is "big" but is now planning to make "big games bigger" as a way of increasing the average attendance at domestic games and is planning "double headers" with men's games next season.

Following on from huge attendances in other European women's leagues, talks are also taking place about hosting some of the opening Women's Super League games on 7 September at Premier League grounds. The Etihad Stadium would be an ideal venue for the first Manchester derby in women's professional football, especially as the opening fixtures fall in a men's international window. Patient donors and controls are labelled on the gel. Positive controls used were expression vectors containing the coding regions of each steroid receptor, respectively.

Negative control was the no template control dH 2 0. Cropped images of stained agarose gels are shown here, while the cropping is explained, and full-length images are shown in Supplementary Fig. All data sets had all data time points. Luciferase readings were normalized to cell viability MTT values.

Donor numbers varied for each cytokine due to some donor samples falling below detection limits. Relative fold change in expression was determined by setting vehicle control to 1. For the gating strategy see Supplementary Fig. We show for the first time that physiologically relevant concentrations of MPA have direct effects on cervical explant tissue ex vivo , to significantly increase R5-tropic, but not X4-tropic HIV-1 replication. However, it should be noted that the concentration of MPA and NET in genital tract tissue is unknown and may or may not differ substantially from that measured in serum.

It would be ideal to perform these studies with transmission-founder clinical isolates, but other reports have shown that these do not readily replicate detectably in ex vivo tissue models Several in vivo mechanisms would not be detected in our non-polarized ex vivo model, such as changes in FGT barrier integrity and permeability. Indeed data from mouse and clinical models show that MPA increases the permeability of the genital barrier 15 and increases HIV-1 transcytosis in primary genital epithelial cells The ex vivo explant model also has some other limitations 83 , but several biological repeats and using fresh tissue still enable meaningful significant results 84 , Nevertheless, the advantages of the ex vivo model are that direct effects on the FGT relevant to HIV- 1 acquisition and replication using the same known concentrations of specific progestins compared to vehicle can be investigated in parallel in the same donor sample, unlike for clinical studies, which also involve indirect effects and multiple confounding behavioural factors such as condom usage.

Other mechanisms whereby contraceptives may affect HIV-1 acquisition in the FGT include changes in soluble mediators of inflammation and innate immunity Several clinical studies show a correlation between increased FGT inflammation and increased HIV-1 acquisition 86 , Expression of these and other select mediators are regulated directly by MPA in genital tract primary or cell line models ex vivo , both in a pro- and an anti-inflammatory manner, at physiologically relevant concentrations, but not by NET, where investigated 31 , 32 , 41 , 91 , The results of our add-back experiments in the TZM-bl indicator cell line suggest that MPA increases R5 HIV-1 replication without a requirement for detectable changes in levels of select soluble secreted mediators from the explant tissue.

Nevertheless, our findings do not exclude a role for changes in other soluble mediators not investigated, nor the possibility that significant small effects undetectable by the power of our study do occur with the mediators investigated, or that longer exposure to progestins may reveal significant changes. This is consistent with our data showing that MPA increased R5-tropic and not X4-tropic viral replication in ectocervical explant tissue.

Others, however, did not detect any change in CCR5 expression levels on T cells in cervicovaginal lavages CVL 17 , or mucosa cells isolated from cytobrush samples from women on DMPA-IM 88 , possibly due to differences in the intrinsic factors of sample populations, methodology or differences in cells between lavage, cytobrushes and tissue. Differences in cell populations between studies may indicate that cells have undergone different degrees of change in surface marker expression, general immune activation, induction of hypoxia or apoptosis 82 , , or induction of wound repair upon mechanical stress due to the harvesting procedures used to generate single cells for flow cytometry analysis and may not accurately reflect prior cell populations.

Alternatively, differences may be due to intrinsic donor population differences. Future experiments using markers for these different cell types could be used to address these questions but are beyond the scope of the present study. However, it should be noted that FGT and systemic HIV-1 target cells are different, although some similarities exist 13 , Alternatively, or in addition there may be an increase in HIV-1 replication in monocytes However, some such reported antagonists are not commercially available.

Further experiments would be required to definitively establish the roles of the GR and PR in these responses in tissue. Our findings suggest that MPA could increase HIV-1 acquisition by the above mechanism once the virus has crossed the epithelial barrier, in the absence of factors such as hypoestrogenism and changes in the microbiome and soluble mediators. However, our data do not exclude a contributing role for any of these or other mechanisms.

Furthermore, our data do not exclude the possibility that the MPA but not NET responses require the presence of other signalling molecules, such as IL-2, present in the media. Indeed, it is likely that MPA, acting alone or together with other signalling pathways, exerts effects on multiple genes and physiological processes relevant to several mechanisms involved in HIV-1 acquisition, given the ubiquitous expression of the GR. While it is unclear and difficult to establish what the impact of the MPA-induced increased HIV-1 replication in the ex vivo model would be on HIV-1 acquisition in vivo , this study does suggest at least one mechanism whereby the impact may be different for MPA compared to NET.
