Wang G, Warrington NM, Evans DM. Partitioning genetic effects on birthweight at classical human leukocyte antigen loci into maternal and fetal components, using structural equation modelling. Int J Epidemiol 2024; 53:dyad142.

Abstract
BACKGROUND Single nucleotide polymorphisms in the human leukocyte antigen (HLA) region in both maternal and fetal genomes have been robustly associated with birthweight (BW) in previous genetic association studies. However, no study to date has partitioned the association between BW and classical HLA alleles into maternal and fetal components. METHODS We used structural equation modelling (SEM) to estimate the maternal and fetal effects of classical HLA alleles on BW. Our SEM leverages the data structure of the UK Biobank (UKB), which includes ∼270 000 participants' own BW and/or the BW of their firstborn child. RESULTS We show via simulation that our model yields asymptotically unbiased estimates of the maternal and fetal allelic effects on BW and appropriate type I error rates, in contrast to simple regression models. Asymptotic power calculations show that we have sufficient power to detect moderate-sized maternal or fetal allelic effects of common HLA alleles on BW in the UKB. Applying our SEM to imputed classical HLA alleles and own and offspring BW from the UKB replicated the previously reported association at the HLA-C locus and revealed strong evidence for maternal (HLA-A*03:01, B*35:01, B*39:06, P <0.001) and fetal allelic effects (HLA-B*39:06, P <0.001) of non-HLA-C alleles on BW. CONCLUSIONS Our model yields asymptotically unbiased estimates, appropriate type I error rates and appreciable power to estimate maternal and fetal effects on BW. These novel allelic associations between BW and classical HLA alleles provide insight into the immunogenetics of fetal growth in utero.

Abstract
BACKGROUND The offspring of parents with Anxiety Disorders (AD) are at high risk for different types of psychopathology, including AD. However, little is known about how parental anxiety during pregnancy and/or the postnatal period might result in alterations in behavior or neurodevelopmental changes in offspring. To examine the effect of parental AD on offspring behavior and neurodevelopment, we conducted a systematic review. METHODS Following PRISMA guidelines, we searched the Web of Science, PubMed, and PsycINFO databases. RESULTS Forty-seven articles met the inclusion criteria for the systematic review. Prenatal maternal anxiety is related to negative temperament, increased attention to fearful vocalizations, decreased alertness, and impaired psychomotor and cognitive development in early and middle childhood. AD during the postnatal period is associated with greater negative temperament, internalizing symptoms, and anxiety symptoms in early childhood, middle childhood, and adolescence. CONCLUSION Our review is the first to demonstrate that prenatal and postnatal AD symptoms impact offspring. Future research should explore the mediating and moderating factors leading to the development of psychopathology in the offspring of parents with AD.

Abstract
Introduction HLA-G plays a central role in immune tolerance at the maternal-fetal interface. The HLA-G gene is characterized by low allelic polymorphism and restricted tissue expression compared with classical HLA genes. HLA-G polymorphism is associated with HLA-G expression and linked to pregnancy complications. However, the association of parental HLA-G polymorphisms with soluble HLA-G (sHLA-G) expression and their roles in recurrent implantation failure (RIF) is unclear. The study aims to systematically review the association of HLA-G polymorphisms with RIF, the association of sHLA-G expression with RIF, and the association of HLA-G polymorphisms with sHLA-G expressions in patients attending in-vitro fertilization (IVF) treatment. Methods Studies that evaluated the association of HLA-G polymorphisms with RIF, the association between sHLA-G expression with RIF, and the association between HLA-G polymorphisms with sHLA-G expressions in patients attending IVF treatment were included. Meta-analysis was performed by random-effect models. Sensitivity analysis was performed by excluding one study each time. Subgroup analysis was performed based on ethnicity. Results HLA-G 14bp ins variant is associated with a lower expression of sHLA-G in seminal or blood plasma of couples attending IVF treatment. The maternal HLA-G*010101 and paternal HLA-G*010102 alleles are associated with RIF risk compared to other alleles. However, single maternal HLA-G 14bp ins/del polymorphism, HLA-G -725 C>G/T polymorphism, or circulating sHLA-G concentration was not significantly associated with RIF in the general population. HLA-G 14bp ins/ins homozygous genotype or ins variant was associated with a higher risk of RIF in the Caucasian population. Discussion Specific HLA-G alleles or HLA-G polymorphisms are associated with sHLA-G expression in couples attending IVF treatment. Several HLA-G polymorphisms may be related to RIF, considering different ethnic backgrounds. A combined genetic effect should be considered in future studies to confirm the association of HLA-G polymorphisms and sHLA-G expressions in relation to RIF.

Abstract
The involvement of the immune system in pregnancy is a controversial subject. The functions of T helper (Th) 1 and Th2 cells have been proposed, that Th1 cytokines promoting allograft rejection may impair pregnancy, whereas Th2-type cytokines suppressing Th1 responses improve allograft tolerance and hence embryonic survival. Maternal-fetal tolerance begins in the uterus; therefore, optimal adaptation to the fetus is the result of a complex interference. The invasion of extravillous trophoblast cells (EVTs) into the decidua and the inner third of the myometrium is essential for a healthy pregnancy. The mechanisms that influence trophoblast invasion are unknown; however, cytokines from uterine natural killer (uNK) cells, NKT cells, macrophages, and T cells appear to be involved. All these cells are major sources of interferon gamma (IFN-γ). Recent studies have shown that IFN-γ can inhibit EVT invasion via a mechanism dependent on an increase in EVT apoptosis and a decrease in matrix metalloproteinases (MMPs). Regarding controversies in this context, this study aimed to comprehensively review the role of IFN-γ and IFN-γ-producing cells in EVT invasion, successful pregnancy, and preeclampsia.

Abstract
During pregnancy, maternal immune system has to balance tightly between protection against pathogens and tolerance towards a semi-allogeneic organism. Dysfunction of this immune adaptation can lead to severe complications such as pregnancy loss, preeclampsia or fetal growth restriction. In the present study we analyzed the impact of the murine MHC class Ib molecule Qa-2 on pregnancy outcome in vivo. We demonstrate that lack of Qa-2 led to intrauterine growth restriction and increased abortion rates especially in late pregnancy accompanied by a disturbed trophoblast invasion and altered spiral artery remodeling as well as protein aggregation in trophoblast cells indicating a preeclampsia-like phenotype. Furthermore, lack of Qa-2 caused imbalanced immunological adaptation to pregnancy with altered immune cell and especially T-cell homeostasis, reduced Treg numbers and decreased accumulation and functional activation of myeloid-derived suppressor cells. Lastly, we show that application of sHLA-G reduced abortion rates in Qa-2 deficient mice by inducing MDSC. Our results highlight the importance of an interaction between HLA-G and MDSC for pregnancy success and the therapeutic potential of HLA-G for treatment of immunological pregnancy complications.

[PMID: 34685432 PMCID: PMC8537334 DOI: 10.3390/life11101061] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/18/2021] [Accepted: 10/05/2021] [Indexed: 12/13/2022] Open
Abstract
Introduction: Immune homeostasis of the intrauterine cavity is vital for pregnancy maintenance. At term or preterm, fetal and maternal tissue inflammation contributes to the onset of labor. Though multiple immune-modulating molecules are known, human leukocyte antigen (HLA)-G is unique to gestational tissues and contributes to maternal–fetal immune tolerance. Several reports on HLA-G’s role exist; however, ambiguity exists regarding its functional contributions during pregnancy and parturition. To fill these knowledge gaps, a systematic review (SR) of the literature was conducted to better understand the expression, localization, function, and regulation of HLA-G during pregnancy and parturition. Methods: A SR of the literature on HLA-G expression and function reported in reproductive tissues during pregnancy, published between 1976–2020 in English, using three electronic databases (SCOPE, Medline, and ClinicalTrials.gov) was conducted. The selection of studies, data extraction, and quality assessment were performed in duplicate by two independent reviewers. Manuscripts were separated into three categories: (1) expression and localization of HLA-G, (2) regulators of HLA-G, and (3) the mechanistic roles of HAL-G. Data were extracted, analyzed, and summarized. Results: The literature search yielded 2554 citations, 117 of which were selected for full-text evaluation, and 115 were included for the final review based on our inclusion/exclusion criteria. HLA-G expression and function were mostly studied in placental tissue and/or cells and peripheral blood immune cells, while only 13% of the studies reported data on amniotic fluid/cord blood and fetal membranes. Measurements of soluble and membranous HLA-G were determined mostly by RNA-based methods and protein by immunostaining, Western blot, or flow cytometric analyses. HLA-G was reported to regulate inflammation and inhibit immune-cell-mediated cytotoxicity and trophoblast invasion. Clinically, downregulation of HLA-G is reported to be associated with poor placentation in preeclampsia and immune cell infiltration during ascending infection. Conclusions: This SR identified several reports supporting the hypothesized role of immune regulation in gestational tissues during pregnancy. A lack of rigor and reproducibility in the experimental approaches and models in several reports make it difficult to fully elucidate the mechanisms of action of HLA-G in immune tolerance during pregnancy.

HLA-DRB1 polymorphism in recurrent pregnancy loss: New evidence for an association to HLA-DRB1*07. J Reprod Immunol 2021; 145:103308. [PMID: 33725525 DOI: 10.1016/j.jri.2021.103308] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 01/15/2021] [Accepted: 03/03/2021] [Indexed: 11/28/2022]
Abstract
Many cases of recurrent pregnancy loss (RPL) defined as ≥3 consecutive pregnancy losses are suggested to be caused by an aberrant maternal immune response against the fetus or trophoblast. Human leukocyte antigen (HLA)-DRB1 and -DQB1 polymorphisms are associated with most autoimmune disorders and studies of HLA-DBB1 polymorphism in RPL patients are thus relevant. In previous studies, the HLA-DRB1*03 allele was found with increased prevalence in RPL patients. We wanted to clarify whether HLA-DRB1 alleles indeed were associated with RPL among women of Caucasian descent. A total of 1078 women with unexplained RPL and 2066 bone marrow donors were HLA-DRB1-typed and subsets were also HLA-DQB1 typed. All patients were initially HLA-DRB1-typed by DNA-based low-resolution techniques and subsets of patients and all controls were typed by high-resolution techniques. Among patients, the HLA-DRB1*07 allele frequency was significantly increased compared with controls; OR 1.29 (95 % CI 1.09-1.52), p < 0.0025; after correction for multiple comparisons pc = 0.031. The HLA-DRB1*07/*07 genotype was highly increased in patients with RPL compared with controls: OR 2.27 (1.31-3.93), p = 0.0027. The frequency of the HLA-DRB1*07 phenotype in RPL patients had increased significantly (p = 0.002) in three studies from our group published 1994-2021. The allele frequency of HLA-DRB1*03 was not increased in RPL patients compared with controls; OR 0.96 (0.83-1.12). In conclusion, the previous association between HLA-DRB1*03 and RPL could not be confirmed in our study whereas an association to HLA-DRB1*07 was detected for the first time. Since the latter association is a new finding, it should be confirmed in future studies.

Abstract
STUDY QUESTION Does the genotype of the surrogate mother modulate the body composition and immunity of her offspring? SUMMARY ANSWER C57BL/6J (B6) progenies carried by immunodeficient NOD SCID (NS) mothers had increased adaptive but decreased innate, immune responsiveness in comparison with the same genotype offspring carried by immunocompetent mothers, B6 and BALB/c (C); the B6 progenies carried by the same genotype mothers also showed higher body fat than the others. WHAT IS KNOWN ALREADY Differences in the major histocompatibility complex (MHC) genes between mother and foetus is considered as an important factor in prenatal embryo development, whereas the impact of such dissimilarity on the phenotype of the mature progeny is unclear. STUDY DESIGN, SIZE, DURATION Transplantation of two-cell mouse embryos into recipient females of the different MHC (H2) genotypes was used as an approach to simulate three variants of the immunogenic mother-foetus interaction: (i) bidirectional immunogenic dialogue between B6 (H2b haplotype) embryos and C (H2d haplotype) surrogate mother; (ii) one-way immunogenic interaction between B6 embryos and immunodeficient NS (H2g7 haplotype) surrogate mother and (iii) reduced immunogenetic dialogue between embryos and surrogate mother of the same H2b haplotype resulting in only a maternal response to HY antigens of male foetuses. Delivered by Caesarean section, pups were fostered by lactating B6 females and weighed after weaning (n = 171). Body mass and composition and innate and adaptive immunity were assessed in selected progeny groups at 9-11 weeks of age. PARTICIPANTS/MATERIALS, SETTING, METHODS The study was performed on the specific pathogen-free mouse, inbred strains C57BL/6J, NOD SCID and BALB/c. Plasma progesterone in pregnant females was measured by enzyme-linked immunosorbent assay (ELISA). Body composition was determined by magnetic resonance spectroscopy using a low-field NMR spectrometer (EchoMRI, USA). To assess peritoneal macrophage responses (innate immunity) to anthrax, lactate dehydrogenase (LDH) and interleukin-1 (IL-1β) were measured in a culture medium 24 h after the addition of both anthrax-lethal factor and anthrax-protective antigen. To assess adaptive immunity, 9-10 males in experimental groups were infected with Helicobacter hepaticus. Faeces collected 2 and 4 weeks after infection was used for quantitative assessment of the H. hepaticus DNA by real-time polymerase chain reaction. IgA, interferon (IFN-γ), tumour necrosis factor (TNFα), interleukin-17 (IL-17) and interleukin-10 (IL-10) in colon tissue and IgG in serum were determined in samples collected 4 weeks after gavage with H. hepaticus using ELISA. For statistical analyses, ANCOVA, post hoc least significant difference (LSD) test, Student's t-test, Spearman rank correlations and χ2 test were performed. P-value <0.05 was considered as a statistically significant difference. MAIN RESULTS AND THE ROLE OF CHANCE ANCOVA with litter size and age as covariates revealed significant effects of the surrogate mother genotype on body mass and percent of fat in their adult progeny (F2149 = 15.60, P < 0.001 and F2149 = 5.02, P = 0.007, respectively). Adult B6 mice carried by B6 surrogate mothers were characterized by a higher percentage of body fat in comparison with offspring that were carried by NS and C females. In comparison with the male offspring carried by the B6 and C mothers, male B6 progenies carried by immunodeficient NS mothers had a higher humoral immune response (serum IgG) against oral infection with H. hepaticus, but lower in vitro macrophage IL-1β reaction to the anthrax. Four weeks after the infection of offspring, concentrations of serum IgG and colon IL-10 correlated positively with maternal progesterone on Day 4 after embryo transfer and negatively with DNA of H. hepaticus. One-way ANOVA confirmed a statistically significant impact of surrogate mother genotype on adaptive (IgG) and innate (IL-1β) immunity (F2.26 = 26.39, P < 0.001 and F2.27 = 5.89, P = 0.008, respectively). LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION The main limitation of our study is the number of combinations of mother and foetus interactions, in particular, transfer of only one embryo genotype was used. Also, it is a descriptive study, which requires further analysis of the epigenetic mechanisms of the observed phenotypic effects of surrogate mother genotype. WIDER IMPLICATIONS OF THE FINDINGS Our experimental data demonstrate that the transfer of inbred embryos to surrogate mothers of the different genotypes is a prospective experimental model for the study of epigenetic effects of the immunogenetic interactions between mother and foetus. The experimental approach tested in our study will be in demand for the development of criteria for choosing surrogate mothers. In particular, immunocompetence of the surrogate mother along with genetic distance of her MHC alleles to the transferred embryos have a significant impact on offspring development.

Abstract
Pregnancy is a unique immunological situation in which a fetus-bearing paternal histocompatibility antigens can survive in a maternal environment without apparent rejection. To face this challenge, cells of the uterine immune system show characteristic changes in absolute number and composition during pregnancy. Particularly relevant to this process are uterine natural killer (uNK) cells and their cell surface receptors, killer immunoglobulin-like receptors (KIRs). The main purpose of this review is to outline the current body of knowledge on the involvement of KIRs in the complications of pregnancy. Implantation depends on the invasion of embryonic trophoblast cells into maternal uterine tissue and remodeling of the uterine spiral arterioles, which is essential for placental perfusion and successful pregnancy. The proper interaction between maternal KIRs and their ligands human leukocyte antigen (HLA) class I molecules, expressed by the extravillous trophoblast cells, is crucial in this process. KIRs are a complex family that includes both activator and inhibitory receptors. The activation profile is genetically determined in each individual and leads to diverse levels of functionality for NK and T cells on engagement with specific HLA class I molecules. An association between different KIR alleles and HLA molecules has been reported in pregnancy complications, supporting the idea of a relevant role of these receptors in successful pregnancy.

Abstract
The HLA class Ib genes, HLA-E, HLA-F, and HLA-G, were discovered long after the classical HLA class Ia genes. The elucidation of their functions had a modest beginning. However, their basic functions and involvement in pathophysiology and a range of diseases are now emerging. Although results from a range of studies support the functional roles for the HLA class Ib molecules in adult life, especially HLA-G and HLA-F have most intensively been, and were also primarily, studied in relation to reproduction and pregnancy. The expression of HLA class Ib proteins at the feto-maternal interface in the placenta seems to be important for the maternal acceptance of the semi-allogenic fetus. In contrast to the functions of HLA class Ia, HLA-G possesses immune-modulatory and tolerogenic functions. Here, we review an accumulating amount of data describing the functions of HLA class Ib molecules in relation to fertility, reproduction, and pregnancy, and a possible role for these molecules in certain pregnancy complications, such as implantation failure, recurrent spontaneous abortions, and pre-eclampsia. The results from different kinds of studies point toward a role for HLA class Ib, especially HLA-G, throughout the reproductive cycle from conception to the birth weight of the child.
