Fig. 1: Overview of immune checkpoint inhibitor targets in cancer immunotherapy.

This schematic illustrates various immune checkpoint inhibitors (ICIs) and their respective targets within the tumor microenvironment. ICIs include various anti-CTLA-4, anti-PD-1 targeting PD-1 receptors, and anti-PD-L1 antibodies. Magrolimab is depicted targeting CD47 to prevent the ‘don’t eat me’ signal on cancer cells, while TIGIT inhibitors interact with TIGIT receptors on T cells. Other ICIs, such as Enoblituzumab and Orlotamab, are shown to target unspecified antigens, Relatlimab binds LAG3 on T cells, and Cobolimab targets TIM3. The figure underscores the complex interplay between the immune system and cancer cells and highlights the multiplicity of potential therapeutic targets for ICIs.
