Geometric parameters that affect the behavior of logic-gated CAR T cells
This study examines Tmod blocker function targeting non-HLA antigens, finding that blocker efficacy depends on antigen height. Primary human T cells were transduced with Tmod constructs and grown in G-Rex plates. The findings established geometric design principles to optimize Tmod selectivity and sensitivity.

Therapeutic Effects of Aβ-Specific Regulatory T Cells in Alzheimer’s Disease: A Study in 5xFAD Mice
This study investigates the therapeutic effects of Aβ-specific Tregs in Alzheimer's disease mice. Purified CD4+CD25+ Tregs were expanded in G-Rex 24-well plates with CD3/28 MACSiBead particles and IL-2. Adoptive transfer improved cognitive function and reduced Aβ and pTAU accumulation in the hippocampus.

Stem cell memory EBV- specific T cells control EBV tumor growth and persist in vivo
This study developed a protocol to expand EBV-specific TSCM-enriched T cells using IL-4, IL-7, and TWS-119. PBMCs were cultured in G-Rex 24-well or 6-well plates. The resulting cells demonstrated superior tumor infiltration, in vivo proliferation, and persistence compared to conventional protocols.

PM21-particle stimulation augmented with cytokines enhances NK cell expansion and confers memory-like characteristics with enhanced survival
This study combined PM21-particles with IL-12/15/18 (CAP) to expand NK cells. CAP-NK cells showed superior expansion in G-Rex 24, G-Rex 6M, and G-Rex 100M. The resulting cells exhibited memory-like properties, enhanced metabolic fitness, and improved in vivo persistence compared to PM21 alone.

NOT gated T cells that selectively target EGFR and other widely expressed tumor antigens
This study describes Tmod cell therapy using a NOT gate to target widely expressed antigens like EGFR while sparing normal cells via an HLA-A*02 blocker. Primary T cells were transduced with CAR or Tmod lentivirus and cultured in G-Rex plates (G-Rex 10 for in vivo studies) to generate effector cells.

Good manufacturing practice-grade generation of CD19 and CD123-specific CAR-T cells using piggyBac transposon and allogeneic feeder cells in patients diagnosed with B-cell non-Hodgkin lymphoma and acute myeloid leukemia
This study presents a GMP protocol for non-viral CAR-T production using piggyBac transposons. Expansion was performed in G-Rex 24 plates (low scale) and G-Rex 10/100 bottles (large scale) with irradiated allogeneic feeders. The feeder improved yield in lymphopenic patients without affecting VCN or phenotype.

IL2 Targeted to CD8+ T Cells Promotes Robust Effector T-cell Responses and Potent Antitumor Immunity
This study describes AB248, a CD8 cis-targeted IL2 that selectively activates CD8+ T cells. B7H3 CAR-T cells were generated by stimulating T cells and transducing them in a 24-well G-Rex plate. The combination of CAR-T and CD8-targeted IL2 resulted in potent antitumor activity and complete tumor rejection in mice.

Assessing a single-cell multi-omic analytic platform to characterize ex vivo-engineered T-cell therapy products
This study utilized the Tapestri platform to characterize CRISPR-Cas9 engineered CD8+ T cells targeting TRAC and TRBC loci. Activated T cells were nucleofected and cultured in 24-well G-Rex plates for 7 days. The analysis quantified on-target edits, off-target events, and translocations with single-cell granularity.

Human platelet lysate enhances in vivo activity of CAR-Vδ2 T cells by reducing cellular senescence and apoptosis
This study compares FBS and human platelet lysate (HPL) for expanding CAR-Vδ2 T cells. Cells expanded in G-Rex with HPL showed greater expansion and in vivo anti-tumor activity. HPL reduction of cellular senescence and apoptosis pathways contributed to improved persistence compared to FBS.

Toll-like receptor 4 signaling activation domains promote CAR T cell function against solid tumors
This study investigated incorporating TLR4 signaling domains into CD19 CARs to improve efficacy against solid tumors. Primary T cells were transduced with CAR lentiviral vectors and expanded for 7-10 days in G-Rex six-well plates. The modified CAR-Ts exhibited enhanced cytotoxicity and cytokine secretion.

Non-viral approaches in CAR-NK cell engineering: connecting natural killer cell biology and gene delivery
This review explores non-viral genetic modification methods for NK cells to produce off-the-shelf CAR-NK therapies. It highlights manufacturing strategies, noting that K562mbIL12-41BBL feeder cells facilitate large-scale expansion of peripheral blood NK cells in gas-permeable static cell culture (G-REX).

Discovery and preclinical development of a therapeutically active nanobody-based chimeric antigen receptor targeting human CD22
This study details the development of a CD22-targeted nanobody-based CAR-T therapy. Primary human T cells were transduced with CD22sdCAR lentivirus and expanded in G-Rex 10M. The 1ug36-sdCAR candidate demonstrated significant in vivo therapeutic activity and favorable tissue specificity in xenograft models.
