Such adjustments are thought to inhibit genital tract immune defences, resulting in decreased cell-mediated responses and immunosurveillance [13]. Whilst the principal web-site of responsiveness to seminal fluid is believed to become the ectocervix in females, [14] maternal responses to semen exposure have been greatest characterised in murine models, where coitus stimulates a classic inflammatory cascade-like uterine response [11]. This benefits in chronologically coordinated endometrial epithelial and stromal responses geared to assistance implantation [7], coordinate immune effector cell recruitment towards the luminal epithelium/decidua, and enable the establishment of pregnancy, each by minimising cell-mediated immunity and modulating abortifacient interferon (IFN)-gamma production [157]. In mice, coitus has also been shown to induce systemic adjustments in cytokine profiles, like decreases in serum IFN-gamma and interleukin (IL)12 (p70), as well as increases in keratinocyte-derived chemokine (KC) and granulocyte-colony stimulating element (G-CSF) [18]. In spite of the crucial role played by these agents, experimental and observational endeavours have remained largely on person cytokines. Nevertheless, cytokines are recognised as operating as networks, exhibiting synergy, antagonism and functional redundancy such that their functional effects must be viewed as within the context of their putative interactions with other mediators in governing their very own concentrations. This degree of manage is vital in ensuring an proper post-coital response, but their functional interactions stay ill-defined. By way of instance, perturbations in seminal plasma IL-1beta, IL-4, IL-8, IL-10 and IFN-gamma profiles have already been correlated with infertility in males, but their interrelationships remain to be described [19, 20]. There is a paucity of data relating towards the extent to which these seminal cytokines profiles are conserved across species, if at all. While mouse and rat cytokines display greater biological cross-reactivity and functional homology than evolutionarily distant species [21], little is identified regarding the potential functional interrelationships between these mediators inside the in vivo setting. This study consequently aimed (i) to characterise physiological cytokine profiles in rat seminal fluid and to compare it to that previously determined in mice and (ii) to apply Bayesian modelling approaches to establish achievable hierarchical/functional interrelationships across cytokines in both species.Components and methods Sample collectionThis study was carried out in strict accordance with the Animals (Scientific Procedures) Act, 1986 (ASPA) and was approved by The University of Leeds. Sexually mature male Wistar rats (body mass 350g; n = 20) had been supply.
