Breast cancer-derived exosomes transmit lncRNA SNHG16 to induce CD73+γδ1 Treg cells

Plasmid construction and siRNA silencing A full-length 2435 bp sequence was cloned into the pCR3.1 vector to

construct the SNHG16 overexpression vector. The sequences of SNHG16-specifific siRNAs were as follows: SNHG16-homo-349, 5′GCCUCUGCUGCUAAUUGUUTT-3′; SNHG16-homo-867, 5′-CCAAGGAGGGACUGUUUAATT-3′ and SNHG16-homo-2004, 5′-CCCAGUGUUGACUCACCAATT-3′. The miR-16–5p mimics, inhibitor and negative

controls were purchased from GenePharma (SupplementaryTable S3).

To manipulate the expression of miR-16–5p in Vδ1 T cells, Vδ1T cells were sorted from peripheral blood and seeded into six-wellplates at 1 × 106 cells/well with 1 ml of medium supplementedwith 10% FBS, 10 μg/ml CD3, 10 μg/ml CD28 and 40 U/mL IL-2.Then, transfection reagent (INVI DNA RNA Transfection Reagent,Invigentech, USA) and miR-16–5p mimics/NC/inhibitor/inhibitor NC (20 μm) were incubated with the cells for 48 h, after which the cells were collected for further experiments.

but not Vδ2+ T cells were revealed to comprise the majority of TILs in all three BC molecular subtypes when gated on CD3 (p < 0.01, Fig. 1b, c). In addition, immunoflfluorescence of frozen sections further confifirmed the dominant distribution of Vδ1+T cells in BC (Fig. 1d). 

To further identify the function of breast cancer-infifiltrating γδ1T cells, BC cell lines (MCF-7, T-47D, MDA-MB-231 and MDA-MB-468) were co-cultured with freshly isolated Vδ1+ T cells frombreast tumour tissue (E:T ratios: 1:1, 5:1 and 10:1). Upon plotting the cell growth curve, the data show that γδ1 T cells did not exert
