Virus-specific T cells for adenovirus infection after stem cell transplantation are highly effective and class II HLA restricted
This phase 1/2 trial evaluated virus-specific T cells (VSTs) for adenovirus infection post-transplant. VSTs were manufactured using G-Rex 10-M devices for 11-12 days. The therapy was highly effective (81% response rate), and efficacy correlated with Class II HLA restriction.

Virus Induced Lymphocytes (VIL) as a novel viral antigen‑specific T cell therapy for COVID‑19 and potential future pandemics
The authors developed Virus Induced Lymphocytes (VIL) for COVID-19 using artificial APCs (VIPR particles). G-Rex plates were used to facilitate rapid expansion (7 days) of SARS-CoV-2 specific T cells. The resulting VILs showed a polyfunctional cytokine profile and effector memory phenotype.

Immunogenic chemotherapy enhances recruitment of CAR-T cells to lung tumors and improves anti-tumor efficacy when combined with checkpoint blockade
This study used a KPROR1 lung cancer model to show that immunogenic chemotherapy (Ox/Cy) enhances ROR1 CAR-T cell infiltration. Clinical human ROR1 CAR-T cells were expanded in G-Rex. The combination of Ox/Cy, CAR-T, and anti-PD-L1 improved survival.

Oncolytic adeno-immunotherapy modulates the immune system enabling CAR T-cells to cure pancreatic tumors
The study combines oncolytic adenovirus (CAdTrio) with HER2-CAR T cells to treat pancreatic cancer. NK cells, expanded in G-Rex devices with feeder cells, were also used in experiments. The combination therapy modulated the tumor microenvironment and improved CAR-T infiltration and efficacy.

CARAMBA: a first-in-human clinical trial with SLAMF7 CAR-T cells prepared by virus-free Sleeping Beauty gene transfer to treat multiple myeloma
This paper outlines the CARAMBA clinical trial for SLAMF7 CAR-T cells generated via Sleeping Beauty transposon. The GMP manufacturing process utilizes G-Rex culture for the expansion of CAR-T cells over 12 days. This is the first clinical trial using advanced Sleeping Beauty technology.

Re-examination of MAGE-A3 as a T-cell Therapeutic Target
The authors investigate MAGE-A3 as a therapeutic target, proposing EPS8L2 as the source of prior TCR-T neurotoxicity. They developed MAGE-A3-directed CARs and TCRs, expanding transduced primary T cells in G-Rex plates. The CARs showed improved selectivity against the off-target peptide.

Deleting DNMT3A in CAR T cells prevents exhaustion and enhances antitumor activity
Knockout of DNMT3A in CAR-T cells prevents exhaustion and enhances antitumor activity. G-Rex-6M culture plates were used for the expansion of gene-edited CAR-T cells. The modified cells retained a stem-like epigenetic program and showed superior tumor control in vivo.

Preclinical Evaluation of 89Zr-Df-IAB22M2C PET as an Imaging Biomarker for the Development of the GUCY2C-CD3 Bispecific PF-07062119 as a T Cell Engaging Therapy
This study evaluates 89Zr-Df-IAB22M2C PET imaging to track CD8+ T cells in a colorectal cancer model treated with a GUCY2C-CD3 bispecific antibody. G-Rex devices were used to expand human T cells prior to adoptive transfer. The tracer effectively monitored dose-dependent T cell infiltration.

RNA-Seq Analysis Reveals CCR5 as a Key Target for CRISPR Gene Editing to Regulate In Vivo NK Cell Trafficking
RNA-seq revealed that ex vivo expansion alters chemokine receptor expression in NK cells, notably upregulating CCR5. G-Rex were used to expand NK cells with feeder cells. CRISPR-mediated CCR5 disruption reduced liver trafficking and increased NK cell presence in circulation in mice.

Microfluidic transfection of mRNA into human primary lymphocytes and hematopoietic stem and progenitor cells using ultra‑fast physical deformations
The study presents a microfluidic device (VECT) for mRNA delivery into primary T cells, NK cells, and HSPCs. G-Rex plates were used for the culture of NK cells during the expansion phase. The method achieved high transfection efficiency and viability without compromising cell function.

Non-transplantable cord blood units as a source for adoptive immunotherapy of leukaemia and a paradigm of circular economy in medicine
This study repurposes non-transplantable umbilical cord blood units to generate myeloid dendritic cells (DCs) and bivalent-leukemia-specific T cells. G-Rex were used to expand DCs from CD34+ cells, facilitating scalable production. The generated T cells showed specificity against WT1 and PRAME.

“Cerberus” T Cells: A Glucocorticoid-Resistant, Multi-Pathogen Specific T Cell Product to Fight Infections in Severely Immunocompromised Patients
The authors generated "Cerberus" T cells (Cb-STs) targeting multiple viruses and Aspergillus fumigatus, with CRISPR/Cas9-mediated glucocorticoid receptor disruption. G-Rex10 devices were used for the culture and expansion of these multi-pathogen specific T cells. Cb-STs maintained function in the presence of dexamethasone.
