Despite their discovery over a century ago, significant questions remain about the development of anti-ABO antibodies and the structural features of ABO antigens that cause hemolytic transfusion reactions. Anti-ABO antibodies develop naturally during the first few months of life, in contrast to other red blood cell (RBC) alloantibodies which form after allogeneic RBC exposure. Anti-ABO antibodies are the most common immune barrier to transfusion and transplantation, but the factors driving their formation are incompletely understood. Some studies suggest that microbes that express glycans similar in structure to the blood group antigens could play a role in anti-blood group antibody formation. While the role of these microbes in clinically relevant anti-blood group antibody formation remains to be defined, the presence of these microbes raises questions about how blood group-positive individuals protect themselves against blood group molecular mimicry. Recent studies suggest that galectins can bind and kill microbes that mimic blood group antigens, suggesting a unique host defense mechanism against microbial molecular mimicry. However, new models are needed to fully define the impact of microbes, galectins, or other factors on the development of clinically relevant naturally occurring anti-blood group antibodies.</div></div>","PeriodicalId":49546,"journal":{"name":"Seminars in Immunology","volume":null,"pages":null},"PeriodicalIF":7.4,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This coordinated process requires the synchronized action of a broad range of cell surface associated proteins and soluble mediators, including growth factors, cytokines and lectins. Collectively, these mediators control cellular communication, signalling, commitment, proliferation, survival and differentiation. Here we discuss the role of galectins – an evolutionarily conserved family of glycan-binding proteins – in the establishment and dynamic remodelling of hematopoietic niches. We focus on the contribution of galectins to B and T lymphocyte development and selection, as well as studies highlighting the role of these proteins in myelopoiesis, with particular emphasis on erythropoiesis and megakaryopoiesis. Finally, we also highlight recent findings suggesting the role of galectin-1, a prototype member of this protein family, as a key pathogenic factor and therapeutic target in myelofibrosis. Through extracellular or intracellular mechanisms, galectins can influence the fate and function of distinct hematopoietic progenitors and fine-tune the final repertoire of blood cells, with critical implications in a wide range of physiologically vital processes including innate and adaptive immunity, immune tolerance programs, tissue repair, regeneration, angiogenesis, inflammation, coagulation and oxygen delivery. Additionally, positive or negative regulation of galectin-driven circuits may contribute to a broad range of blood cell disorders.</div></div>","PeriodicalId":49546,"journal":{"name":"Seminars in Immunology","volume":null,"pages":null},"PeriodicalIF":7.4,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the formation of the immune system initiates before birth in a sterile environment, an emerging body of literature indicates that the neonatal immune system is influenced by a first wave of external stimuli that includes signals from the maternal microbiota. A second wave of stimulus begins after birth and must be tightly regulated during the neonatal period when colonization of the host occurs concomitantly with the maturation of the immune system, requiring a fine adjustment between establishing tolerance towards the commensal microbiota and preserving inflammatory responses against pathogenic invaders. Besides integrating cues from commensal microbes, the neonatal immune system must also regulate responses triggered by other environmental signals, such as dietary antigens, which become more complex with the introduction of solid food during the weaning period. This “window of opportunity” in early life is thought to be crucial for the proper development of the immune system, setting the tone of subsequent immune responses in adulthood and modulating the risk of developing chronic and metabolic inflammatory diseases. Here we review the importance of host-microbiota interactions for the development and maturation of the immune system, particularly in the early-life period, highlighting the known mechanisms involved in such communication. This discussion is focused on recent data demonstrating microbiota-mediated education of innate immune cells and its role in the development of lymphoid tissues.</p></div>","PeriodicalId":49546,"journal":{"name":"Seminars in Immunology","volume":null,"pages":null},"PeriodicalIF":7.8,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S104453232400023X/pdfft?md5=d018d4af0ce3c913e6674c37e433dcb9&pid=1-s2.0-S104453232400023X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141090243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
