Objective
2
To observe the expression of T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) in tumor tissue and peripheral blood CD8
+
T cells in patients with triple-negative breast cancer(TNBC),and to explore the effect of tiragolumab on the function of CD8
+
T cells in the peripheral blood of these patients.
Methods
2
The expression of TIGIT in tumor tissue of patients with TNBC was analyzed using The Cancer Genome Atlas(TCGA) database and immunohistochemical staining. Flow cytometry was employed to assess the co-expression of TIGIT and programmed death-1 (PD-1) in peripheral blood CD8
+
T cells,as well as their cytokine secretion. A co-culture model of CD8
+
T cells and TNBC cell lines,HCC-1
937 and MDA-MB-231,was established. The effect of tiragolumab on the anti-tumor activity of CD8
+
T cells in patients with TNBC was investigated using flow cytometry and confocal fluorescence imaging.
Results
2
The expression of TIGIT in tumor tissue and peripheral blood CD8
+
T cells of patients with TNBC was significantly increased(
P
<
0.05). Compared with the healthy control group,the TNBC group showed a significantly larger number of TIGIT
+
PD-1
+
CD8
+
T cells in the peripheral blood and significantly reduced secretion of interferon gamma (IFN-γ),tumor necrosis factor-α(TNF-α),and ginkgolide B(GB) by CD8
+
T cells;specifically,TIGIT
+
CD8
+
T cells demonstrated significantly reduced secretion compared with TIGIT
-
CD8
+
T cells(
P
<
0.05). Following treatment with tiragolumab,TIGIT
+
CD8
+
T cells exhibited increased secretion of IFN-γ and TNF-α(
P
<
0.05). In the co-culture model,tiragolumab restored the apoptosis-inducing ability of CD8
+
T cells in patients with TNBC,and this ability was further enhanced when it was combined with envafolimab.
Conclusion
2
Tiragolumab restores the tumor-killing function of CD8
+
T cells by improving their immunosuppression. The combination of tiragolumab with envafolimab can further enhance its anti-tumor effect.
