Activation of IRAK4 drives activation of nuclear factor kappa B (NF-κB) and so promotes cell survival, inflammation, and other aspects of the adaptive immune response. However, the IRAK4 pathway can be coopted by cancers and lead to the survival and proliferation of malignant cells. Inappropriate IRAK4 activity has been linked with the progression of myelodysplastic syndrome (MDS), other hematologic malignancies, and some solid tumors, and preclinical cancer models indicate that IRAK4 inhibition has anti-tumor effects. As such, inhibition of IRAK4 is an emerging and attractive target for tumor suppression. The growing interest in IRAK4 motivated the 1st Symposium on IRAK4 in Cancer held in October 2022 to bring together IRAK4 researchers and clinicians to discuss new insights into the biology of IRAK4 and development of IRAK4 inhibitors. Presentations and discussions at the meeting provided updates on the biology of IRAK4 and its links with mutations in the spliceosome, new outcomes from preclinical models that indicate synergy between inhibitors of IRAK4 and FLT3 and BTK inhibitors, and an update on the clinical development of the investigational IRAK4 inhibitor emavusertib, currently being assessed in ongoing phase 1/2 clinical studies in hematologic cancers and several solid tumors.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139835421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is considered an incurable disease, the enhanced understanding of this neoplasm has led to new treatments, which have improved patients’ life expectancy. Large amounts of data have been generated through different studies in the settings of clinical trials, prospective registries, and real-world cohorts, which have incorporated laboratory tests, flow cytometry, molecular markers, cytogenetics, diagnostic images, and therapy into routine clinical practice. In this review, we described how these data can be processed and analyzed using different models of artificial intelligence, aiming to improve accuracy and translate into clinical benefit, allow a substantial improvement in early diagnosis and response evaluation, speed up analyses, reduce labor-intensive process prone to operator bias, and evaluate a greater number of parameters that provide more precise information. Furthermore, we identified how artificial intelligence has allowed the development of integrated models that predict response to therapy and the probability of achieving undetectable measurable residual disease, progression-free survival, and overall survival leading to better clinical decisions, with the potential to inform on personalized therapy, which could improve patients’ outcomes. Overall, artificial intelligence has the potential to revolutionize multiple myeloma care, being necessary to validate in prospective clinical cohorts and develop models to incorporate into routine daily clinical practice.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139683340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interleukin (IL)-22 producing type 3 innate lymphoid cells (ILC3) protect epithelial tissues against chemo(radio)therapy-induced damage, suppress alloreactive T cells and mitigate acute GvHD symptoms after allogeneic HCT. Relatively high numbers of ILC before and after allogeneic HCT has been associated with significantly reduced tissue damage and less acute GvHD. While most transplantation conditioning and GvHD prophylaxis regimens are aimed at eliminating host and alloreactive donor lymphocytes, the effect of these regimens on ILC remain elusive. Here, we studied the effect of conditioning chemotherapy and immunosuppressive agents on the survival, proliferation, activation and function of human ILC3 in vitro. Tonsil-derived ILC3 were activated and incubated with agents commonly used to prevent and treat GvHD. While fludarabine, rapamycin, mycophenolic acid and prednisolone suppressed ILC3 to a similar degree as T cells, the effect of other agents, including cyclosporine A, methotrexate, imatinib, ibrutinib and ruxolitinib, was milder on ILC3 than on T cells. ILC3 are less sensitive to immunosuppressants potentially because of their expression of functionally active ATP Binding Cassette Subfamily B Member 1 (ABCB1) drug exporter proteins. This suggests less intracellular accumulation of immunosuppressive agents, which renders ILC3 resistant to these compounds. The present findings may help to develop strategies to simultaneously maintain the tissue protective properties of ILC3 and at the same time suppress alloreactive lymphocytes, which is important in the prevention and treatment of acute GvHD.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133532885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It usually contains α- and β-thalassemia, most of common mutation types of which can be detected. However, it’s inclined to miss rare thalassemia mutation types. Here, we analyzed the molecular and hematological characteristics of seven cases with rare β-thalassemia -90 (C>T) (HBB: c.-140 C>T) mutation. Five of them carried β-90 (C>T) heterozygous mutation with a β+ thalassemia trait. One case was αSEA/β-90 genotype with decreasing MCV and MCH obviously, and the other was a β+/β0 intermediate thalassemia patient with β-90/βCD17 genotype, presenting with moderate anemia. A pedigree of one case was analyzed subsequently. It was found that the proband’s maternal grandfather and mother were carriers of α3.7/β-90 double heterozygous thalassemia, who presented that MCV and MCH were decreased normally or slightly, and HbA2 was increased. The proband and his aunt were β-90 (C>T) carriers. It’s necessary to point that the MCV and MCH were much higher in carrier of α3.7/β-90 genotype compared with either αSEA/β-90 genotype or β-90 heterozygous mutation. In this study, we explore the genotypes and phenotypes of four diverse β-90、αSEA/β-90、α3.7/β-90、β-90/βCD17 thalassemia mutations, which enriches the gene profile of β-thalassemia mutation in Chinese population.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115426536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathogenesis of ITP is complex and involves dysregulation of the immune system. This review aimed to summarize the current knowledge of the cytokine profile in ITP and its potential implications for diagnosis, treatment, and prognosis. Several studies have reported that ITP patients have an altered cytokine profile from that of healthy individuals. Specifically, there is evidence of an imbalance of pro-inflammatory (interleukin (IL)-6, tumor necrosis factor (TNF)-α, interferon (IFN)-γ) and anti-inflammatory cytokines (IL-10, TGF-β). The cytokine profile in ITP appears to be heterogeneous, with different patterns observed in different subsets of patients. For example, some studies have reported a Th1-type cytokine profile, characterized by elevated levels of IFN-γ and TNF-α, while others have reported a Th2-type cytokine profile, characterized by elevated levels of IL-4 and IL-10. There is also evidence of a shift from a Th1 to a Th2 cytokine profile in some patients over time. The cytokine profile in ITP may have important implications for diagnosis, treatment, and prognosis. Targeting specific cytokines or cytokine pathways may also represent a promising therapeutic approach for ITP. Further studies are needed to better understand the heterogeneity of the cytokine profile in ITP and its potential implications for clinical management.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114785290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pain from vaso-occlusive crises (VOCs) is the most common symptom experienced by patients with SCD; thus, pain management constitutes a significant role in this patient population. We hypothesized that physicians with less favorable attitudes toward SCD patients are less likely to follow pain management guidelines. In this cross-sectional convenience sample survey, we aimed to assess the adherence of physicians in our institute to guidelines for the management of SCD pain crises and study the factors that are associated with non-adherence to these guidelines. Most surveyed physicians were early in their career and were found to adhere to the recommendations of using opioids and NSAIDs as a first-line therapy and avoiding using meperidine. On the other hand, some analgesic practices deviated from the recommendations, including less frequent assessment and reassessment of pain and response to pain medications and less frequent use of opioid patient-controlled analgesia (PCA). It is noteworthy that the frequency and severity of untreated pain in patients with SCD are associated with higher mortality, thus appropriate comprehensive care for such a vulnerable population should be prioritized and optimized. Although we did not find an association between the providers’ attitudes toward SCD patients and their pain management practices, improving these attitudes will promote the provider–patient relationship and its therapeutic outcomes. We conclude that the physicians taking care of SCD patients in our institute adhere to some of the guidelines in the field more than others. We also conclude that they have negative attitudes toward SCD patients; nevertheless, these did not affect their pain management practices.","PeriodicalId":101407,"journal":{"name":"Frontiers in hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132479623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gene therapy, on the other hand, offers a promising alternative, using cells from the patient that have been corrected ex vivo. However, due to the complexity of cells with a compromised DNA repair pathway, it has been difficult to achieve success in treating FA with gene therapy, despite advancements in the treatment of other blood disorders.

This review aims to explore the concept of COSBL and its potential as a paradigm-shifting strategy in the prevention of GVHD, in the context of the existing modalities for the prevention of GVHD and the preclinical and clinical studies on COSBL. The unique property of abatacept (CTLA4Ig) is not just limited to dampening T-cell activation. The salutary effect of abatacept on natural killer (NK) cells and Tregs alike provides a unique opportunity to dissociate T-cell-mediated GVHD from NK cell-mediated graft-versus-leukemia.
