T cell-based therapies hold immense promise, but their production remains time-consuming and technically complex. Here, we present a protocol that streamlines the activation and lentiviral transduction of primary human T cells with artificial receptors. We describe steps for T cell isolation, lentivirus production, and the simultaneous activation/transduction of T cells. By eliminating magnetic T cell activation beads, sequential steps, and lengthy spinoculation, this protocol significantly enhances efficiency, scalability, and accessibility for research and therapeutic applications.

When investigating cellular responses to viral infections, there is a need to quantitatively distinguish between dying cells, infected cells, and cells that are both infected and dying. Here, we present a protocol to simultaneously detect porcine reproductive and respiratory syndrome virus (PRRSV) infection and cell death using a flow cytometry double-staining approach. We describe steps for cell seeding, infection, and collection; staining dead cells; sample fixation; and cell permeabilization.

The study aimed to evaluate the safety and efficacy of simultaneous integrated dose reduction intensity-modulated radiotherapy (SIR-IMRT) in patients with locally advanced non-small-cell lung cancer (LA-NSCLC). In the SIR-IMRT conhort, the prescribed irradiation dose was 60 Gray (Gy) for the planning gross tumor volume (PGTV) and 54 Gy for the planning target volume (PTV), while in the conventional intensity-modulated radiotherapy (C-IMRT) cohort, it was 60 Gy for both PGTV and PTV. The SIR-IMRT group demonstrated better overall survival (OS) than the C-IMRT group, with a median OS of 37.

Here, we present a protocol to perform a time-kill assay (TKA) to quantify bacterial burden at multiple time points using colony-forming units and most probable number readouts simultaneously. We describe steps for preparing inoculum, experimental conditions, and sampling bacterial counts. We then detail procedures for quantification and analysis.

Recent advances in molecular and cell biology and imaging have unprecedentedly enabled multiscale structure-functional studies of entire metabolic pathways from atomic to micrometer resolution and the visualization of macromolecular complexes , especially if these molecules are expressed with appropriately engineered and easily detectable tags. However, genome editing in eukaryotic cells is challenging when generating stable cell lines loaded with large DNA cargoes. To address this limitation, here, we have conceived biGMamAct, a system that allows the straightforward assembly of a multitude of genetic modules and their subsequent integration in the genome at the locus with high efficacy, through standardized cloning steps.
