Background: The polymorphisms of the FOXP3 gene may mediate abnormalities in Tregs, leading to an imbalance in maternal-fetal immune tolerance and ultimately resulting in recurrent spontaneous abortion (RSA). This meta-analysis aims to assess the potential association between FOXP3 polymorphisms and susceptibility to RSA using five specific single nucleotide polymorphisms (SNPs).
Materials And Methods: By conducting a comprehensive search across databases such as EMBASE, PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, and CBM, we identified suitable studies for inclusion in the meta-analysis. The data extracted from these studies were subjected to analysis using Stata SE 15. To assess the degree of association, we utilized the odds ratio (OR) along with its corresponding 95% confidence intervals (CI). Five specific single nucleotide polymorphisms (SNPs) were employed in assessing the connection between FOXP3 gene polymorphisms and RSA.
Results: The meta-analysis demonstrated a significant association between several polymorphisms (rs3761548, rs2232365, rs2232368, rs2280883, and rs2294021) and susceptibility to RSA. Conversely, the FOXP3 rs5902434 polymorphism was not associated with susceptibility to RSA.
Conclusion: Our meta-analysis suggests that these genetic variations within the FOXP3 gene might play a role in the progression of RSA disease. Meanwhile, large-scale studies that consider multiple factors are needed to validate this finding.

Background: Intestinal transplantation (ITx) represents the only curative option for patients with irreversible intestinal failure. Nevertheless, its rejection rate surpasses that of other solid organ transplants due to the heightened immunological load of the gut. Regulatory T-cells (Tregs) are key players in the induction and maintenance of peripheral tolerance, suggesting their potential involvement in modulating host vs.

The helminth Trichinella spiralis, through its excretory-secretory (ES L1) products, induces immune regulatory mechanisms that modulate the host's immune response not only to itself, but also to bystander antigens, foreign or self in origin, which can result in the alleviation of inflammatory diseases. Under the influence of ES L1, dendritic cells (DCs) acquire a tolerogenic phenotype and the capacity to induce Th2 and regulatory responses. Since ES L1 products represent a complex mixture of proteins and extracellular vesicles (TsEVs) the aim of this study was to investigate the impact of TsEVs, isolated from ES L1 products, on phenotypic and functional characteristics of DCs and to elucidate whether TsEVs could reproduce the immunomodulatory effects of the complete ES L1 product.

Long-term, immunosuppression-free allograft survival has been induced in human and nonhuman primate (NHP) kidney recipients after nonmyeloablative conditioning and donor bone marrow transplantation (DBMT), resulting in transient mixed hematopoietic chimerism. However, the same strategy has consistently failed in NHP heart transplant recipients. Here, we investigated whether long-term heart allograft survival could be achieved by cotransplanting kidneys from the same donor.

Object: We aim to explore the immunomodulatory properties of T cells on different titanium nanotubes and the key immunological factors involved in this process.
Methods: Transcriptome data from GEO database of healthy people and healthy implants were used to analyze cell infiltration and factor distribution of adaptive immune using bioinformatics tools. T cells from activated rat were cultured on titanium nanotubes that were prepared by anodization with different diameters (P-0, NT15-30 nm, NT40-100 nm, NT70-200 nm).

Tertiary lymphoid structures (TLS), formerly recognized as Crohn's-like structures, serve as crucial biomarkers for evaluating the progression of colorectal cancer (CRC). Understanding their spatial distribution, cellular composition, and interactions within CRC is paramount for comprehending the immune response in the tumor microenvironment (TME). TLS are comprised of a T-cellular compartment and a B-cellular compartment, the latter encompassing follicular dendritic cells (FDCs), high endothelial venules (HEVs), and lymphatic vessels.
