Chimeric antigen receptor T (CAR-T) cell therapy has become an attractive approach for treating hematological malignancies. However, the accessibility of this is limited by factors such as complex manufacturing process, capacity facilities and requirement highly skilled workforce manual steps CAR-T production. To minimize processes, field shifting towards closed automated systems, including analytical tools that offer intermittent monitoring cells in Therefore, label-free technologies...
Abstract Live microbial contamination poses high risks to cell and gene therapies, threatening manufacturing processes patient safety. Rapid, sensitive detection of live microbes in complex environments, such as CAR‐T cultures, remains an urgent need. Here, innovative sample‐to‐result workflow is introduced using digital loop‐mediated isothermal amplification (dLAMP), enhanced by Electrostatic Microfiltration (EM)‐based enrichment, for rapid sterility testing. By rationally designing primers...
IRF-7 mediates robust production of type I IFN via MyD88 the TLR9 pathway in plasmacytoid dendritic cells (pDCs). Previous vitro studies using bone marrow-derived lacking either Irf7 or Irf3 have demonstrated that only IRF-3 is required for IFN-β TLR4 pathway. Here, we show essential both induction and IL-1β responses mice. Mice were defective IL-1β, an IFN-β-induced pro-inflammatory cytokine, after LPS challenge. response to was impaired IRF-7-deficient macrophages, but not cells. Unlike...
In keeping with the rule of "form follows function", morphological aspects a cell can reflect its role. Here, it is shown that cellular granularity lymphocyte, represented by intrinsic side scatter (SSC), potent indicator state and function. The lymphocyte increases from naïve to terminal effector state. High-throughput cell-sorting yields SSC
Cytokines, crucial in immune modulation, impact disease progression when their secretion is dysregulated. Existing methods for profiling cytokine suffer from time-consuming and labor-intensive processes often fail to capture the dynamic nature of responses. Here, iSECRETE, an integrated platform that enables synchronous cell activation, wash-free, target-responsive protein detection single-cell IFN-γ analysis within 30 min at room temperature presented. By incorporating a DNA proximity assay...
Abstract While adoptive cell therapies have revolutionized cancer immunotherapy, current autologous chimeric antigen receptor (CAR) T manufacturing face challenges in scaling to meet patient demands. CAR production still largely rely on fed-batch, manual, open processes that lack environmental monitoring and control, whereas most perfusion-based, automated, closed-system bioreactors currently suffer from large footprints working volumes, thus hindering process development scaling-out. Here,...
Assuring that cell therapy products are safe before releasing them for use in patients is critical. Currently, compendial sterility testing bacteria and fungi can take 7-14 days. The goal of this work was to develop a rapid untargeted approach the sensitive detection microbial contaminants at low abundance from volume samples during manufacturing process therapies. We developed long-read sequencing methodology using Oxford Nanopore Technologies MinION platform with 16S 18S amplicon detect...

Severe mosquito bite allergy (SMBA) is a manifestation of chronic active Epstein-Barr virus (CAEBV) infection defined by necrotic ulceration the stings. CAEBV with SMBA has high mortality rate as most patients eventually develop fulminant and refractory hemophagocytic lymphohistiocytosis (HLH). However, how self-resolving escalates to systemic lethal HLH remains unclear. Through comprehensive immune profiling patient her healthy monozygotic twin, we found that both twins were seropositive...
