SpletPD-1/PD-L1 interaction is thought to play a role in preventing destructive autoimmunity, especially during inflammatory conditions. The best example is in the stomach, where PD-1 expression protects the gastrin expressing G-cells from the immune system during Helicobacter pylori -provoked inflammation.

Splet27. avg. 2024 · (A) The interaction of PD-1/PD-L1 causes tumor immune tolerance. The PD-1/PD-L1 interaction stimulates the downstream signals to suppress T cell activation, resulting in tumor cell survival. (B) Breakdown of the PD-1/PD-L1 interaction reactivates T cells and related immune responses. Splet30. maj 2024 · PD-1 binds to one of its two ligands: PD-L1 (also known as B7-H1 and CD274) or PD-L2 (known as B7-DC and CD273). This interaction triggers an inhibitory signal to the activated T cells, which induces T cell apoptosis, anergy, and functional exhaustion ( Figure S1, Supplementary Materials) [ 10 ].
SpletAptamers, known as chemical antibodies, are single-stranded oligonucleotides with high affinity. In this work, we take a cell-SELEX with the engineered PD-L1-expressing cells as a target to obtain the aptamer, designated PL1, which specifically binds to PD-L1 with a Kd value of 95.73 nM, resulting in the inhibition of PD-1/PD-L1.
Splet22. avg. 2024 · If PD-L1 and PD1 interact, this will lead to hampering of the T-cell and therefore to tumor growth. Because of that, anti-PD1 or anti PD-L1 drugs have been developed to specifically block the PD-1 PD-L1 interaction, and therefore boost the host anti-tumor immune response and inhibit tumor growth.
