Figure Lengend Snippet: Impact of chemotherapy on percentage of ( A ) cytotoxic NK cells of lymphocytes and NK-cell-specific activating receptors. ( B – E ) 5 × 10 6 PBMCs were treated for 24 h under cell culture conditions with either carboplatin (2 µg/mL, open circles), cisplatin (1 µg/mL, open triangles), etoposide (0.5 µg/mL, open squares), vincristine (0.05 µg/mL, open diamonds), or the cyclophosphamide metabolite (4-HPC, 1 µg/mL, open hexagons). After 72 h of culturing, cells were analyzed for NKp30, NKp44, NKp46, NKG2D, and CD226 expression, using flow cytometry. ( A ) Relative number of cytotoxic NK cells (CD3 − , CD56 dim ) in lymphocytes. ( B – E ) Geometric mean fluorescence intensity (gMFI) of respective activating receptor of cytotoxic NK cells after chemotherapy. Data represent at least four biological replicates. Means and SEM are indicated as black lines and error bars, respectively. For statistical analysis, repeated measures ANOVA with appropriate post hoc test was used; * p < 0.05 vs., ** p < 0.01 versus untreated control (medium).

Article Snippet: Incubation with the following antibodies in a total volume of 100 μL was conducted for 20 min at RT: CD3-VioGreen (REA613, 1:200), CD56-APC-Vio770 (REA196, 1:200), CD226-VioBlue (REA1040, 1:50); CD335 (NKp46)-Vio Bright B515 (REA808, 1:50), CD337 (NKp30)-PE (REA823, 1:75), CD336 (NKp44)-APC (REA1163, 1:75), and CD314 (NKG2D)-PE-Vio 770 (REA1228, 1:75), all from Miltenyi Biotec.

Article Title: Using peptide-exchange systems to interrogate peptide-specific KIR binding to HLA Class I

doi: 10.64898/2026.03.03.708729

Figure Lengend Snippet: (A) Display of ULBP1 and CD155 on CombiCells detected by mAbs and NKG2D-Fc, and DNAM-1-Fc, respectively. (B&C) KIR2DL1+ and KIR2DL1-NK-cell degranulation (CD107a upregulation) in response to ULBP1, CD155, and HLA-C*05:01 displayed on CombiCells. (C) Three types of HLA-C*05:01 were tested, all containing P2 (IIDKSGSTV); wild-type, open and dipeptide exchanged. Data from three independent experiments with NK cells from separate donors are shown.

Article Snippet: For binding assays, APC-conjugated Fc fusion protein (NKG2D-Fc (R&D Systems, Cat. No: 1299-NK) or DNAM-1-Fc (R&D Systems, Cat. No: # 666-DN) or KIR-Fc (R&D Systems, KIR2DL1-Fc (Cat. No: 1844-KR-050), KIR2DL3-Fc (Cat. No: 2014-KR-050), KIR2DS4-Fc (Cat. No: 1847-KR-050) (3.6 μg mL -1 ) was added at 25 μL per well and incubated for 30 min at 4 °C in the dark.
