Chimeric antigen receptor (CAR) T cell dysfunction is a major barrier to achieving lasting remission in hematologic cancers, especially chronic lymphocytic leukemia (CLL). We have shown previously that Δ133p53α, an endogenous isoform of the human TP53 gene, decreases expression with age cells, and reconstitution Δ133p53α poorly functional cells can rescue proliferation [A.

Natural killer (NK) cells are frequently expanded for the clinic using irradiated, engineered K562 feeder expressing a core transgene set of membrane-bound (mb) IL15 and/or mbIL21 together with 41BBL. Prior comparisons mbIL15 to NK expansion lack key attributes resulting cells, including their high-dimensional phenotype, polyfunctionality, breadth and potency cytotoxicity, cellular metabolism, activity in xenograft tumor models. Moreover, despite multiple rounds stimulation, studies...
Abstract Patients with multiple myeloma (MM) treated B-cell maturation antigen (BCMA)-specific chimeric receptor (CAR) T cells usually relapse BCMA+ disease, indicative of CAR T-cell suppression. CD200 is an immune checkpoint that overexpressed on aberrant plasma (aPCs) in MM and independent negative prognostic factor for survival. However, not present cell lines, a potential limitation current preclinical models. We engineered lines to express at levels equivalent those found aPCs show...
Early expansion and long-term persistence predict efficacy of chimeric antigen receptor T cells (CARTs)
<h3>Background</h3> The success of CAR T-cell immunotherapy depends on the differentiation status and metabolic fitness product. In current CART manufacturing protocols, activation leads to irreversible differentiation. Our recent work showed that nonactivated T-cells can be generated within 24 hours, eliminating need for or <i>ex vivo</i> expansion. We assert this process retains maximal Interleukin 18 (IL-18) is a proinflammatory cytokine regulates adoptively transferred T-cells, IL-18...
Activated T cells undergo a metabolic shift to aerobic glycolysis support the energetic demands of proliferation, differentiation, and cytolytic function. Transmembrane glucose flux is facilitated by transporters (GLUT) that play vital role in cell reprogramming anti-tumour GLUT isoforms are regulated at level expression subcellular distribution. GLUTs also display preferential selectivity for carbohydrate macronutrients including glucose, galactose, fructose. GLUT5, which selectively...
