Rapid and sustained T cell-based immunotherapy against invasive fungal disease via a combined two step procedure
The paper describes a manufacturing strategy for Aspergillus-specific T cells (ATCs). A short-term expansion (STE) protocol using G-Rex devices allowed for the generation of clinically relevant numbers of functional ATCs within 12 days.

The prospect of universal coronavirus immunity: characterization of reciprocal and non-reciprocal T cell responses against SARS-CoV2 and common human coronaviruses
The study investigates T cell responses to SARS-CoV-2 and endemic coronaviruses. It describes a protocol to generate universal multi-coronavirus specific T cells (MCVSTs) by expanding PBMCs in G-Rex gas-permeable containers, yielding robust cell numbers for potential adoptive immunotherapy.

Refining chimeric antigen receptors via barcoded protein domain combination pooled screening
This paper describes a pooled screening strategy for CAR domain combinations using DNA barcoding. G-Rex plates were utilized for co-culturing transduced T cells with tumor cells during repeated antigen stimulation assays to identify CAR constructs with superior expansion and proliferation.

Improving the cytotoxic response of tumor-infiltrating lymphocytes towards advanced stage ovarian cancer with an oncolytic adenovirus expressing a human vIL-2 cytokine
The study evaluates an oncolytic adenovirus expressing vIL-2 to boost TIL therapy for ovarian cancer. Autologous TILs were expanded from patient tumor fragments using six-well G-Rex plates as part of the 'young' TILs expansion protocol.

Boosting cytotoxicity of adoptive allogeneic NK cell therapy with an oncolytic adenovirus encoding a human vIL-2 cytokine for the treatment of human ovarian cancer
This study demonstrates that an oncolytic adenovirus encoding vIL-2 enhances NK cell cytotoxicity against ovarian cancer. Patient PBMCs used for humanized mouse models were expanded and rested using 6-well G-Rex plates with TILs media.

Neoantigen-targeted CD8+ T cell responses with PD-1 blockade therapy
The study analyses neoantigen-specific T cells in melanoma patients. Isolated neoTCRs were engineered into donor T cells, which were expanded in 24-well G-Rex plates. The expanded cells were used to validate TCR specificity and cytotoxicity against autologous tumor cell lines.

Potently neutralizing human mAbs against the zoonotic pararubulavirus Sosuga virus
The study isolates neutralizing human mAbs against Sosuga virus from a survivor. Hybridoma cell lines secreting these mAbs were expanded in 6-well G-Rex plates to produce sufficient antibodies for purification and subsequent functional characterization.

Assessment of anti-CD20 antibody pre-treatment for augmentation of CAR-T cell therapy in SIV-infected rhesus macaques
This study evaluates anti-CD20 pre-treatment for enhancing SIV-specific CAR-T cell therapy in macaques. CAR-T cells were manufactured using G-Rex 6-well plates for expansion. While anti-CD20 treatment increased initial CAR-T expansion, the cells failed to persist long-term, and viral loads were not significantly affected.

Technological and Manufacturing Innovation Drive Improved Access to Engineered T Cell Therapies
The paper presents a low-cost, point-of-care CAR-T manufacturing process. It uses the Sepax C-Pro for cell processing and G-Rex devices for cell expansion. The study demonstrates that this simplified workflow produces highly functional CAR-T cells, comparable to standard methods, supporting decentralized production.

Extracellular Vesicles from Immune Cells: A Biomedical Perspective
This review explores the role of small extracellular vesicles (sEVs) derived from various immune cells. It highlights a protocol using G-Rex to produce and isolate large amounts of human NK cell-derived sEVs, demonstrating their potential for clinical application in cancer therapy.
Publications
Process engineering of natural killer cell-based immunotherapy
This review discusses the biomanufacturing of NK cell therapies, covering cell sources, expansion methods, and process control. It identifies G-Rex as a commonly used culture system for clinical-scale NK cell production due to their gas-permeable membranes, facilitating efficient cell expansion.

Activated T cell therapy targeting glioblastoma cancer stem cells
The study develops an activated T cell (ATC) therapy targeting glioblastoma cancer stem cells. It compares antigen sources, finding synthetic peptide pools most effective. T cells were co-cultured with antigen-loaded dendritic cells in G-Rex 100 containers for activation and rapid proliferation over 12 days.
