Article Title: Enhanced Fc and complement activity of Fc‐modified avelumab boosts anti‐tumor activity but promotes NK cell fratricide
Article Snippet: The B‐cell line, Ramos, was obtained from ATCC (Manassas, VA, USA) and maintained in R10 media. .. PD‐1 + Ramos and PD‐L1 + Ramos were generated as previously described using cDNA sequences cloned into Sleeping Beauty vectors under the control of the EF‐1α promoter., A natural killer cell line (GFP‐CD16‐NK‐92) that had been transduced to express GFP and high‐affinity CD16 (V/V) was obtained from the ATCC and maintained in supplemented R10 media as described., CD16 expression by GFP‐CD16‐NK92 was routinely monitored and remained high throughout culture (Supplementary figure ). ..

Microphysiological system “NNTI-chip” models the preferential migration of natural killer (NK) cells toward different neutrophil subtypes in scenario 1. (A) Side channels A and B of the NNTI-chip housed two different human neutrophil subtypes (i.e., N1 and N2 neutrophils, N1 and N0 neutrophils, or N2 and N0 neutrophils, respectively) acting as two competitive signals, and NK cells in the central channel were allowed to migrate preferentially into either side channel A or B. Both neutrophils and NK cells were embedded in a 3D collagen hydrogel to mimic the extracellular matrix of the tumor tissue. Created with Rhino 7 and BioRender.com. (B) Representative 10X bright-field and epifluorescence images showing N1 neutrophils (orange) in side channel A, N2 neutrophils (magenta) in side channel B, and NK cells (blue) in the central channel immediately after loading of NK cells into the NNTI-chip. The three channels are separated and interconnected by PDMS microposts. Scale bar, 100 μm. (C) The workflow of a typical experiment for scenario 1. NK cell migration toward neutrophils in both side channels and NK cell motility after migration into side channels were quantified as readouts. Created with BioRender.com.

Poxin improves the anti-tumor efficacy of PD-L1-CAR-NK cells against H460 lung cancer. A. PD-L1-CAR expression levels in NK-92 cells. Abbreviations: TM = Transmembrane; Co-stim=Co-stimulatory; SD=Signaling domain. B. Cytotoxicity of CAR-NK-92 cells with or without Poxin expression against K562 and H460 cells, measured over 2 h. C. Experimental scheme for the H460 xenograft mouse model (n = 8). D. Tumor sizes were measured using digital calipers at the indicated time points. E. Representative tumor images from both groups at 28 days post-H460 inoculation. F. Tumor volumes were calculated. Error bars in panels B and D represent mean ± SEM. Mouse experiments were independently repeated twice with similar outcomes. Statistical significance was assessed using Two-way ANOVA (D) or Student's t -test (F).
