Abstract
PROBLEM Pro-inflammatory phenomena drive preterm delivery (PTD). Hydrogen sulfide is a gasotransmitter with anti-inflammatory properties produced through the activity of the enzyme cystathionine-γ-lyase (CSE), and its impact was studied in models of normal delivery and PTD in mice. METHOD OF STUDY Female CSE+/+ and CSE-/- mice were mated with male CSE+/+ mice; mating was done with drinking water unsupplemented and supplemented with cysteine. The pregnancy rate was monitored. PTD was induced by the intraperitoneal injection of bacterial lipopolysaccharide (LPS) on day 14.5 of pregnancy. Mice were sacrificed for tissue collection and splenocyte isolation after 6 and 12 h. Isolated splenocytes were stimulated for the production of tumor necrosis factor-alpha (TNFα), interleukin (IL)-10 and interferon-gamma (IFNγ); TNFα and vascular endothelial growth factor (VEGF) were measured in the fetuses and the placenta. RESULTS The successful pregnancy rate was lower in CSE-/- mice and it was restored with cysteine supplementation. CSE deficiency was associated with higher tissue concentrations of TNFα in the fetuses, attenuated IL-10 responses and higher IFNγ production from splenocytes. CSE deficiency was not associated with PTD. Following PTD induction, CSE-/- mice did not show attenuated IL-10 responses but the production of TNFα and IFNγ was lowered over-time; placental VEGF was also increased over-time. CONCLUSIONS CSE deficiency has an unfavorable impact on pregnancy. H2 S deficiency through CSE does not drive PTD but mediates pro-inflammatory phenomena in fetuses.

Abstract
PROBLEM Pro-inflammatory responses of pathogen recognition receptors (PRR) are implicated in preterm delivery (PTD). Dectin-2 is one PRR recognizing unselective carbohydrate structures; its participation in PTD has never been studied before. METHOD OF STUDY In an experimental model, PTD was induced in female pregnant wild-type (WT) mice and mice with homologous deficiency for dectin-2 by the intraperitoneal injection of bacterial lipopolysaccharide (LPS) on day 14 of pregnancy. Time to delivery and fetal mortality were recorded. Challenged mice were killed for tissue collection and splenocyte isolation 6 hours later. Concentrations of tumour necrosis factor-alpha (TNFα), interleukin (IL)-1α, and IL-1β were measured. RESULTS Delivery was induced significantly earlier in WT than dectin-2-/- mice; however, fetal mortality was higher among dectin-2-/- mice. Candida albicans challenge could not lead to these changes. Sacrifice experiments showed that LPS challenge led to significant increase of TNFα, IL-1α, and IL-1β in maternal tissues of WT; this was further enhanced for TNFα and IL-1β in dectin-2-/- mice. Pre-treatment with the prostaglandin inhibitor diclofenac delayed time to delivery of WT mice, but not of dectin2-/- mice. TNFα stimulation of splenocytes of dectin2-/- mice was enhanced with the addition of anti-TLR4 and decreased in the presence of lipid A. CONCLUSIONS Dectin-2 delays LPS-induced PTD by enhancing the production of pro-inflammatory cytokines.

Abstract
To investigate the impact of carriage of single nucleotide polymorphisms (SNPs) of the Toll-like receptor-4 (TLR4) and of autophagy-related gene 16-like-1 (ATG16L1) in preterm delivery (PTD).A prospective cohort of 145 pregnant women was studied. Women were prospectively followed-up until delivery. Genotyping for rs4986790 (Asp299Gly transition) and rs4986791 (Thr399Ile transition) of TLR4 and for rs2241880 of ATG16L1 was done by PCR-restriction fragment length polymorphism. The primary study endpoint was the impact of carriage of minor alleles of TLR4 on early PTD before gestational week 32. Associations with human chorionic gonadotrophin (hCG) were also analyzed. Peripheral blood mononuclear cells were isolated from 15 healthy women and stimulated for cytokine production.No difference in clinical characteristics was observed between women delivering full term and preterm. The frequency of early PTD was 25% among women carrying minor alleles of TLR4 and 6.8% among women carrying major alleles (P: .032). Odds ratios for PTD were 3.85 among women carrying the GG genotype of rs2241880 and major alleles of TLR4 and 0.26 among carriers of GG genotype and minor alleles of TLR4 (P: .030). The co-presence of GG genotype of rs2241880 and hCG above 70 U/L was an independent variable for PTD. Stimulated production of interleukin-6 was greater among women with GG genotypes of rs2241880.Minor alleles of SNPs of TLR4 predispose to early PTD. The GG genotype of rs2241880 of ATG16L1 is associated with PTD when hCG is supra-elevated.

Early changes of the heat-shock protein 60 to 70 ratio as prediction of miscarriage in pregnancy. Am J Reprod Immunol 2019; 81:e13087.

Abstract
PROBLEM To study the balance of circulating heat shock protein (HSP)60 and HSP70 in pre-term delivery. METHOD OF STUDY A two-stage approach was used. At first stage, we run retrospective analysis of prospective collected clinical data, and at a second stage, we studied an animal model of pre-term delivery (PTD). Blood samples were collected for prenatal screening in 3629 women. Samples from 23 women with miscarriage before gestational week 21 and 53 well-matched comparators for age, body mass index, parity, and previous miscarriage with full-term pregnancy were depicted. Women with risk factors were excluded. HSP60 and HSP70 were measured by an enzyme immunosorbent assay. PTD was induced after injection of low dose of bacterial lipopolysaccharide; mice were killed for the measurement of HSP60 and HSP70 in blood and tissues. The study endpoint was the association of the HSP60 to HSP70 ratio to miscarriage. RESULTS A ratio >6 could distinguish between women who will miscarry from women with term pregnancies with sensitivity 60%, specificity 81.8%, positive predictive value 81.8%, and negative predictive value 60% (OR: 6.750, P = 0.025). Mice of the LPS-group PTD had this ratio significantly increased in maternal serum, placentas, and embryos compared to the sham-operation group. Gene expression of hsp60/70 remained in tissues unaltered. CONCLUSION A HSP60/HSP70 ratio equal to or more than 6 until gestational week 12 is accompanied with great likelihood for miscarriage. A similar ratio applies in an animal model of PTD induced by low-dose LPS.

Abstract
Dexamethasone (Dex) is an effective glucocorticoid in treating inflammation and preventing rejection reaction. However, the side effects limit its clinical application. To improve its druggable profile, the conjugates of RGD-peptide-modified Dex were presented and their enhanced anti-inflammation activity, minimized osteoporotic action, and nanoscaled assembly were explored. (RGD stands for Arg-Gly-Asp. Standard single letter biochemical abbreviations for amino acids have been used throughout this paper.) In respect of the rejection reaction, the survival time of the implanted myocardium of the mice treated with 1.43 µmol/kg/d of the conjugates for 15 consecutive days was significantly longer than that of the mice treated with 2.5 µmol/kg/d of Dex, and the conjugates, but not Dex, exhibited no toxic action. At a single dose of 14.3 µmol/kg (100 times minimal effective dose, 0.143 µmol/kg), the conjugates induced no liver, kidney, or systemic toxicity. At the dose of 1.43 µmol/kg, the conjugates, but not Dex, prolonged the bleeding time of the mice, and inhibited the thrombosis of the rats. In water and rat plasma, the conjugates formed nanoparticles of 14-250 and 101-166 nm in diameter, respectively. Since the nanoparticles of ~100 nm in size cannot be entrapped by macrophages in the circulation, RGDF-Dex would particularly be worthy of development, since its nanoparticle diameter is 101 nm.

Abstract
The design of 3D constructs with adequate properties to instruct and guide cells both in vitro and in vivo is one of the major focuses of tissue engineering. Successful tissue regeneration depends on the favorable crosstalk between the supporting structure, the cells and the host tissue so that a balanced matrix production and degradation are achieved. Herein, the major occurring events and players in normal and regenerative tissue are overviewed. These have been inspiring the selection or synthesis of instructive cues to include into the 3D constructs. We further highlight the importance of a multiscale perception of the range of features that can be included on the biomimetic structures. Lastly, we focus on the current and developing tissue-engineering approaches for the preparation of such 3D constructs: top-down, bottom-up and integrative. Bottom-up and integrative approaches present a higher potential for the design of tissue engineering devices with multiscale features and higher biochemical control than top-down strategies, and are the main focus of this review.
