TLDR
These inhibitors have great potential for treating chronic infections, especially when combined with therapeutic vaccines, and have been shown to enhance ex vivo effector T‐cell responses from patients with chronic viral, bacterial, or parasitic infection.Abstract:
The development of chronic infections and cancer is facilitated by a variety of immune subversion mechanisms, such as the production of anti-inflammatory cytokines, induction of regulatory T (Treg) cells, and expression of immune checkpoint molecules, including CTLA-4 and PD-1. CTLA-4, expressed on T cells, interacts with CD80/CD86, thereby limiting T-cell activation and leading to anergy. PD-1 is predominantly expressed on T cells and its interaction with PD-L1 and PD-L2 expressed on antigen-presenting cells (APCs) and tumors sends a negative signal to T cells, which can lead to T-cell exhaustion. Given their role in suppressing effector T-cell responses, immune checkpoints are being targeted for the treatment of cancer. Indeed, antibodies binding to CTLA-4, PD-1, or PD-L1 have shown remarkable efficacy, especially in combination therapies, for a number of cancers and have been licensed for the treatment of melanoma, nonsmall cell lung cancer, and renal and bladder cancers. Moreover, immune checkpoint inhibitors have been shown to enhance ex vivo effector T-cell responses from patients with chronic viral, bacterial, or parasitic infection, including HIV, tuberculosis, and malaria. Although the data from clinical trials in infectious diseases are still sparse, these inhibitors have great potential for treating chronic infections, especially when combined with therapeutic vaccines.read more

Regulation of the immune checkpoint PD-L1 by microRNAs
TL;DR: It is demonstrated that PD-L1 expression in human dermal lymphatic endothelial cells (HDLECs) can be induced with the treatment of pro-inflammatory cytokines IFN-y and TNF-a, and miR-155 can act in a cell type-specific manner to temporally release PD- L1 immunosuppression to regulate the balance between immune tolerance and autoimmunity.

TL;DR: Among previously untreated patients with metastatic melanoma, nivolumab alone or combined with ipilimumab resulted in significantly longer progression-free survival than ipILimumab alone, and in patients with PD-L1-negative tumors, the combination of PD-1 and CTLA-4 blockade was more effective than either agent alone.
