S309-CAR-NK cells bind the Omicron variants in vitro and reduce SARS-CoV-2 viral loads in humanized ACE2-NSG mice

This study demonstrates that S309-CAR-NK cells can bind to SARS-CoV-2 variants and reduce viral loads in humanized ACE2-NSG mice. Primary NK cell expansion and CAR-NK cell maintenance were performed using G-REX wells.

CAR-T cell expansion platforms yield distinct T cell differentiation states

This study compares CAR-T expansion in Prodigy, Xuri, G-Rex, and bags. G-Rex (500M) cultures yielded effector memory-enriched cells. Hypoxic culture in G-Rex increased the proportion of naïve/stem central memory-like cells, suggesting oxygenation is a key factor in T cell differentiation during manufacturing.

A synthetic cytotoxic T cell platform for rapidly prototyping TCR function

This study introduces the YT-rCTL/KFRET system for rapid TCR functional profiling. YT-Indy based effector cell lines were subcultured in 24-well G-Rex plates. The platform allows for the recombinant expression of TCRs and antigens to assess cytotoxic responses via a granzyme-activatable reporter.

Proteasome inhibition enhances the anti-leukemic efficacy of chimeric antigen receptor (CAR) expressing NK cells against acute myeloid leukemia

This study demonstrates that proteasome inhibitors sensitize AML cells to NK cell killing. NK cells were activated by co-culture with irradiated feeder cells in G-Rex 10 vessels. The combination of bortezomib pre-treatment and CAR-NK infusion significantly delayed tumor growth and prolonged survival in xenograft models.

IL-2-armored peptide-major histocompatibility class I bispecific antibodies redirect antiviral effector memory CD8+ T cells to induce potent anti-cancer cytotoxic activity with limited cytokine release

This study presents IL-2-armored GPS molecules that selectively expand and redirect CMV-specific CD8+ T cells. Expansion assays were conducted in 6-well and 24-well G-REX plates. The approach induced potent cytotoxicity against cancer cells with a reduced cytokine release profile compared to conventional TCEs.

Placental circulating T cells: a novel, allogeneic CAR- T cell platform with preserved T- cell stemness, more favorable cytokine profile, and durable efficacy compared to adult PBMC- derived CAR- T

This study identifies placental circulating T cells as a superior source for allogeneic CAR-T therapy. T cells were activated and expanded in G-Rex plates. The resulting CAR-T cells retained stemness markers, exhibited a favorable cytokine profile, and demonstrated durable in vivo efficacy against lymphoma.

Optimisation of a primary human CAR-NK cell manufacturing pipeline

This study optimizes CAR-NK manufacturing using primary NK cells. Expansion was performed in 48-well G-Rex plates using irradiated feeder cells. Adult PB-NK cells showed superior yield and cytotoxicity. The protocol achieved high transduction efficiency and scalable expansion suitable for clinical use.

Generating universal anti-CD19 CAR T cells with a defined memory phenotype by CRISPR/ Cas9 editing and safety evaluation of the transcriptome

This study presents a method to generate universal CAR-T cells with a defined memory phenotype by editing TRAC and B2M genes. Cells were cultured in G-Rex 24-well plates. The safety of the editing was confirmed via CRISPRroots analysis, and the cells showed effective anti-tumor activity in vitro.

Perspectives for the Use of Umbilical Cord Blood in Transplantation and Beyond: Initiatives for an Advanced and Sustainable Public Banking Program in Greece

This report describes the operation of Greek public UCB banks. It highlights initiatives to reuse non-transplantable units for cell therapy. Specifically, it details the expansion of immunomagnetically selected CD34+ cells in G-Rex to differentiate into dendritic cells for generating leukemia-specific T cells.

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.
