Mesenchymal ovarian cancer cells promote CD8+ T cell exhaustion through the LGALS3-LAG3 axis
Cancer cells often metastasize by undergoing an epithelial-mesenchymal transition (EMT). Although abundance of CD8 + T-cells in the tumor microenvironment correlates with improved survival, mesenchymal cancer cells acquire greater resistance to antitumor immunity in some cancers. We hypothesized the...

| Shrnutí: | Cancer cells often metastasize by undergoing an epithelial-mesenchymal transition (EMT). Although abundance of CD8
+
T-cells in the tumor microenvironment correlates with improved survival, mesenchymal cancer cells acquire greater resistance to antitumor immunity in some cancers. We hypothesized the EMT modulates the immune response to ovarian cancer. Here we show that cancer cells from infiltrated/inflamed tumors possess more mesenchymal cells, than excluded and desert tumors. We also noted high expression of
LGALS3
is associated with EMT in vivo, a finding validated with in vitro EMT models. Dissecting the cellular communications among populations in the tumor revealed that mesenchymal cancer cells in infiltrated tumors communicate through
LGALS3
to
LAG3
receptor expressed by CD8
+
T cells. We found CD8
+
T cells express high levels of
LAG3
, a marker of T cell exhaustion. The results indicate that EMT in ovarian cancer cells promotes interactions between cancer cells and T cells through the
LGALS3
-
LAG3
axis, which could increase T cell exhaustion in infiltrated tumors, dampening antitumor immunity. |
