Abstract
Endometriosis is a debilitating gynecological disease defined as the presence of endometrium-like epithelium and/or stroma outside the uterine cavity. The most commonly affected sites are the pelvic peritoneum, ovaries, uterosacral ligaments, and the rectovaginal septum. The aberrant tissue responds to hormonal stimulation, undergoing cyclical growth and shedding similar to appropriately located endometrial tissue in the uterus. Common symptoms of endometriosis are painful periods and ovulation, severe pelvic cramping, heavy bleeding, pain during sex, urination and bowel pain, bleeding, and pain between periods. Numerous theories have been proposed to explain the pathogenesis of endometriosis. Sampson's theory of retrograde menstruation is considered to be the most accepted. This theory assumes that endometriosis occurs due to the retrograde flow of endometrial cells through the fallopian tubes during menstruation. However, it has been shown that this process takes place in 90% of women, while endometriosis is diagnosed in only 10% of them. This means that there must be a mechanism that blocks the immune system from removing endometrial cells and interferes with its function, leading to implantation of the ectopic endometrium and the formation of lesions. In this review, we consider the contribution of components of the Major Histocompatibility Complex (MHC)-I-mediated antigen-processing pathway, such as the ERAP, TAP, LMP, LNPEP, and tapasin, to the susceptibility, onset, and severity of endometriosis. These elements can induce significant changes in MHC-I-bound peptidomes that may influence the response of immune cells to ectopic endometrial cells.

Abstract
Endoplasmic reticulum aminopeptidase 2 (ERAP2) is a proteolytic enzyme involved in adaptive immunity. The ERAP2 gene is highly polymorphic and encodes haplotypes that confer resistance against lethal infectious diseases, but also increase the risk for autoimmune disorders. Identifying how ERAP2 influences susceptibility to these traits requires an understanding of the selective pressures that shaped and maintained allelic variation throughout human evolution. Our review discusses the genetic regulation of haplotypes and diversity in naturally occurring ERAP2 allotypes in the global population. We outline how these ERAP2 haplotypes evolved during human history and highlight the presence of Neanderthal DNA sequences in ERAP2 of modern humans. Recent evidence suggests that human adaptation during the last ~10,000 years and historic pandemics left a significant mark on the ERAP2 gene that determines susceptibility to infectious and inflammatory diseases today.

Abstract
Spondyloarthritis (SpA) is a multifactorial chronic inflammatory disease affecting the axial skeleton (axSpA) and/or peripheral joints (p-SpA) and entheses. The disease's pathogenesis depends on genetic, immunological, mechanical, and environmental factors. Endoplasmic reticulum aminopeptidase 1 (ERAP1) is a multifunctional enzyme that shapes the peptide repertoire presented by major histocompatibility complex (MHC) class I molecules. Genome-wide association studies (GWAS) have identified different single nucleotide polymorphisms (SNPs) in ERAP1 that are associated with several autoimmune diseases, including axSpA. Therefore, a deeper understanding of the ERAP1 role in axSpA could make it a potential therapeutic target for this disease and offer greater insight into its impact on the immune system. Here, we review the biological functions and structure of ERAP1, discuss ERAP1 polymorphisms and their association with axSpA, highlight the interaction between ERAP1 and human leukocyte antigen (HLA)-B27, and review the association between ERAP1 SNPs and axSpA clinical parameters.

Abstract
The human leukocyte antigen (HLA)-B*27 family of alleles is strongly associated with ankylosing spondylitis (AS), a chronic inflammatory disorder affecting the axial and peripheral joints, yet some HLA-B*27 variants not associated with AS have been shown. Since no major differences in the ligandome of associated compared to not-associated alleles have emerged, a plausible hypothesis is that the quantity rather than the quality of the presented epitopes makes the difference. In addition, the Endoplasmic Reticulum AminoPeptidases (ERAPs) 1 and 2, playing a crucial role in shaping the HLA class I epitopes, act as strong AS susceptibility factors, suggesting that an altered peptidome might be responsible for the activation of pathogenic CD8+ T cells. In this context, we have previously singled out a B*27:05-restricted CD8+ T cell response against pEBNA3A (RPPIFIRRL), an EBV peptide lacking the B*27 classic binding motif. Here, we show that a specific ERAP1/2 haplotype negatively correlates with such response in B*27:05 subjects. Moreover, we prove that the B*27:05 allele successfully presents peptides with the same suboptimal N-terminal RP motif, including the self-peptide, pDYNEIN (RPPIFGDFL). Overall, this study underscores the cooperation between the HLA-B*27 and ERAP1/2 allelic variants in defining CD8+ T cell reactivity to suboptimal viral and self-B*27 peptides and prompts further investigation of the B*27:05 peptidome composition.

Abstract
Antigen (Ag)-trimming aminopeptidases belong to the oxytocinase subfamily of M1 metallopeptidases. In humans, this subfamily contains the endoplasmic reticulum aminopeptidases 1 and 2 (ERAP1 and 2) and the insulin-responsive aminopeptidase (IRAP, synonym oxytocinase), an endosomal enzyme. The ability of these enzymes to trim antigenic precursors and to generate major histocompatibility class-I ligands has been demonstrated extensively for ERAP1, less for ERAP2, which is absent in rodents, and exclusively in the context of cross-presentation for IRAP. During 20 years of research on these aminopeptidases, their enzymatic function has been very well characterized and their genetic association with autoimmune diseases, cancers, and infections is well established. The mechanisms by which these proteins are associated to human diseases are not always clear. This review discusses the Ag-trimming-independent functions of the oxytocinase subfamily of M1 aminopeptidases and the new questions raised by recent publications on IRAP and ERAP2.

Abstract
In 1938, Corneille Heymans received the Nobel Prize in physiology for discovering that oxygen sensing in the aortic arch and carotid sinus was mediated by the nervous system. The genetics of this process remained unclear until 1991 when Gregg Semenza while studying erythropoietin, came upon hypoxia-inducible factor 1, for which he obtained the Nobel Prize in 2019. The same year, Yingming Zhao found protein lactylation, a posttranslational modification that can alter the function of hypoxia-inducible factor 1, the master regulator of cellular senescence, a pathology implicated in both post-traumatic stress disorder (PTSD) and cardiovascular disease (CVD). The genetic correlation between PTSD and CVD has been demonstrated by many studies, of which the most recent one utilizes large-scale genetics to estimate the risk factors for these conditions. This study focuses on the role of hypertension and dysfunctional interleukin 7 in PTSD and CVD, the former caused by stress-induced sympathetic arousal and elevated angiotensin II, while the latter links stress to premature endothelial cell senescence and early vascular aging. This review summarizes the recent developments and highlights several novel PTSD and CVD pharmacological targets. They include lactylation of histone and non-histone proteins, along with the related biomolecular actors such as hypoxia-inducible factor 1α, erythropoietin, acid-sensing ion channels, basigin, and Interleukin 7, as well as strategies to delay premature cellular senescence by telomere lengthening and resetting the epigenetic clock.

Abstract
Type 1 diabetes mellitus (T1D) is a multifactorial organ specific autoimmune disease which originates from the destruction of insulin-producing beta cells within the pancreatic islets by autoreactive CD8+ T lymphocytes. The autoimmune responses are raised against autoantigenic peptides presented in the context of the Major Histocompatibility Complex (MHC) class I molecules. Peptides are generated in the cytoplasm of the beta cell by degradation through the proteasome activity and other proteases. Proteolytic intermediate protein fragments are then vehicled into the endoplasmic reticulum (ER) by transporters associated with antigen processing TAP1 and TAP2. In the ER, Endoplasmic Reticulum Aminopeptidase 1 (ERAP1) and 2 (ERAP2) shape the intermediate proteins to produce the optimal peptide size for loading into the MHC class I molecules. Subsequently complexes are shuttled to the cell surface for antigen presentation. Genome Wide Association Studies (GWAS) have identified different SNPs of ERAP1 associated to several autoimmune diseases and in particular the T1D-related ERAP1 SNP rs30187 encoding for K528R ERAP1. An association between the ER stress and the increased exposure of beta cells to the immune system has been hypothesized to further contribute to the etiopathogenesis. In particular in a recent study by Thomaidou et al. 2020 (doi: https://doi.org/10.2337/db19-0984) the posttranscriptional regulation of ERAP1 is shown to shaping the recognition of the preproinsulin (PPI) signal peptide by cytotoxic T lymphocytes. In the light of foregoing ERAP1 inhibitors could potentially prevent the activation of epitope-specific autoimmune-promoting T cells and their cytokine production; further regulating ERAP1 expression at posttranscriptional level under stress conditions of the beta cells could help to reverse autoimmune process through limiting epitope-presentation to autoreactive T cells. In this article we provide a perspective on the role of ERAP1 as implicated in the pathogenesis of insulin-dependent diabetes mellitus by reviewing studies reported in literature and discussing our own experimental evidence.
