Discussion In this section, we discuss the mechanisms responsible for lymphomagenesis in the various inborn errors of immunity and provide an overview of the treatment. Defects in Immune Responses That Predispose to Lymphomagenesis in PIDDs The complex immune mechanisms and their interplay that predisposes to neoplastic transformation of B or T cells and development of lymphomas in PIDD patients has not been fully elucidated. However, it is expected that the etiology in most cases is multifactorial and related to a dynamic regulation of immune response and environmental triggers (Figure 3). An underlying intrinsic susce...

In this study, the immunohistochemistry results demonstrated that DEPDC1 was high-expressed in breast cancer tissues compared with the paired adjacent normal breast tissues, and its tendency at protein level was consistent with mRNA level from TCGA data. Moreover, DEPDC1 mRNA level revealed the strongest association with poor prognosis and development in breast cancer. In vitro assays showed that DEPDC1 overexpression resulted in significant promotion of proliferation by regulating cell cycle in MCF-7 cells, whilst an opposite effect was found in the MDA-MB-231 cells with DEPDC1 deletion. Notably, further investigation ind...

Conclusions: CAR T cell therapies have demonstrated the clinical benefits of harnessing our body's own defenses to combat tumor cells. Similar research is being conducted on lesser known modifications and gene-modified immune cells, which we highlight in this review. Introduction Chimeric antigen receptors and engineered T cell receptors (based on previously identified high affinity T cell receptors) function by redirecting T cells to a predefined tumor-specific (or tumor-associated) target. Most of these modifications use retroviral or lentiviral vectors to integrate the construct, and most of the receptors ...

In conclusion, the high structural diversity of these compounds pinpoints the significant range of inhibition strategies that can be conceived to target the class I methyltransferases. Although the structural details of the various members of this family are unique, the success stories of drug design for several enzymes belonging to this family portends the likely achievement of discovering potent and selective inhibitors of METTL3/METTL14. Author Contributions AF and AP wrote the manuscript. ZI revised and edited manuscript and prepared figures. Funding This work was supported by Associazione Italiana Ricerca sul Canc...

A T cell receptor (TCR) recognizing melanoma-associated antigen-A (MAGE-A3/A6) is currently used in clinical trials involving adoptive transfer of TCR-transduced T cells for patients with metastatic cancer. To be eligible for this TCR immunotherapy, tumor specimens from patients must show homogeneous expression of MAGE-A3 and/or MAGE-A6. Currently-available antibodies recognize additional members of the MAGE-A family and/or are cross-reactive because they were raised by epitopes shared among the MAGE-A family members.MAGE-A3 and MAGE-A6 are members of the MAGE-A family of twelve homologous proteins. The MAGE-A proteins are...

Selinexor (KPT-330) is a selective inhibitor of nuclear export (SINE) which specifically targets XPO1 (Exportin 1)-mediated nuclear export, leading to increased nuclear retention of major tumor suppressor proteins and inducing selective apoptosis in cancer cells. Several phase I and II clinical trials demonstrate evidence of anti-cancer activity of Selinexor in solid tumors (i.e metastatic prostate cancer (PMID: 29487219), advanced refractory bone or soft tissue sarcoma (PMID: 27458288) and non-small cell lung cancer (PMID: 28647672); as well as, hematological malignancies, including non-Hodgkin lymphoma (PMID: 28468797), ...

Objective: To investigate the clinical features of 2nd hematological malignancies post to the initial cancer treatment.METHODS: A retrospective study was performed to analyze the available clinical data of 116 patients diagnosed with 2nd hematologic malignancies after treatment of various malignant tumors from June 1998 to June 2018 at Sun Yat-sen University cancer center.RESULTS: The characteristics of the 116 patients diagnosed with 2nd hematological cancer post to initial cancer treatment were indicated as following: 62 males and 54 females. The primary tumor category was grouped as (according to ICD-10 International Di...

Conclusions. APAVAC is a simple method for AV with high clinical impact in very bad situations. It could be used in combination with other therapy and for residual disease control. Further clinical studies are planned in solid C as well as in HM.DisclosuresRouquet: URODELIA: Employment. Frayssinet: URODELIA: Employment.
