Chimeric CTLA4-CD28-CD3z T Cells Potentiate Antitumor Activity against CD80/CD86–Positive B Cell Malignancies

CTLA4-chimeric antigen receptor T cells were found to accumulate in tumors and are toxic to myeloid-derived suppressor cells without signs of severe GVHD and CRS in preclinical models.

ADCK1 Activates the β-Catenin/TCF Signaling Pathway to Promote the Growth and Migration of Colon Cancer Cells

Researchers found an increase in ADCK1 (AarF domain-containing kinase 1) expression in clinical specimens of colon cancer and animal models. Downregulation of ADCK1 expression inhibited the colony formation and infiltration of cancer cells, in vivo tumorigenesis, migration, and organoid formation.

Phase II-Like Murine Trial Identifies Synergy between Dexamethasone and Dasatinib in T-Cell Acute Lymphoblastic Leukemia

Scientists performed an shRNA screen in vitro and in vivo in T-cell acute lymphoblastic leukemia cell lines and patient derived xenograft samples to identify vulnerabilities in the pTCR/TCR pathway and identified a critical role for the kinase LCK in cell proliferation.

Combining Ibrutinib and Checkpoint Blockade Improves CD8+ T-Cell Function and Control of Chronic Lymphocytic Leukemia in Em-TCL1 Mice

By using the Eµ-TCL1 adoptive transfer mouse model of chronic lymphocytic leukemia, scientists observed that ibrutinib effectively controled leukemia development, but also resulted in significantly lower numbers of CD8+ effector T-cells, with lower expression of activation markers, as well as impaired proliferation and effector function.

Outcome of Haploidentical versus Matched Sibling Donors in Hematopoietic Stem Cell Transplantation for Adult Patients with Acute Lymphoblastic Leukemia: A Study from the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation

Investigators retrospectively analyzed adult patients with acute lymphoblastic leukemia who underwent their first allogeneic stem cell transplantation in first or second complete remission between 2012 and 2018, either from a T cell replete Haplo or matched sibling donor donor.

Autophagy-Mediated Activation of Mucosal-Associated Invariant T Cells Driven by Mesenchymal Stem Cell-Derived IL-15

Investigators found that MSCs did not influence the proliferation of mucosal-associated invariant (TMAIT) cells but strikingly induced an activated phenotype with an increased expression of CD69, TNF-α, IFN-γ, and granzyme B.
