About us
PD-L1 checkpoint is operative in peripheral tissues and serves as a negative regulator of T-cells to help control local inflammatory responses and maintain self-tolerance. It is constitutively expressed on a subset of macrophages, but may be rapidly upregulated in a number of different tissue types and by tumors in response to interferon-gamma and other inflammatory mediators. https://www.bocsci.com/tag/pd-l1-3.html
