TLDR
The way forward for this class of novel agents lies in the ability to understand human immune responses in the tumor microenvironment, which will provide valuable information regarding the dynamic nature of the immune response and regulation of additional pathways that will need to be targeted through combination therapies to provide survival benefit for greater numbers of patients.Abstract:
Immune checkpoint therapy, which targets regulatory pathways in T cells to enhance antitumor immune responses, has led to important clinical advances and provided a new weapon against cancer. This therapy has elicited durable clinical responses and, in a fraction of patients, long-term remissions where patients exhibit no clinical signs of cancer for many years. The way forward for this class of novel agents lies in our ability to understand human immune responses in the tumor microenvironment. This will provide valuable information regarding the dynamic nature of the immune response and regulation of additional pathways that will need to be targeted through combination therapies to provide survival benefit for greater numbers of patients.read more

PD-1 Blockade for Improving the Antitumor Efficiency of Polymer-Doxorubicin Nanoprodrug.
TL;DR: The results suggest that the therapeutic efficiency of HA-Psi-DOX nanoparticles is significantly improved when combined with checkpoint inhibitors anti-PD-1 antibody (α-PD1) due to the neutralization of immunosuppression by blocking the interaction between PD-L1 and PD-1.

TL;DR: Functionally, TNFR2+ Treg frequency was inversely correlated with interferon-gamma (IFN-γ) production by effector T cells, and was uniquely able to suppress TNFR 2+ T effectors.

IgG cooperativity – Is there allostery? Implications for antibody functions and therapeutic antibody development
TL;DR: While available research does not support the existence of antigen-induced conformational allosteric cooperativity in IgGs, there is substantial evidence for configurational allostery due to glycosylation and sequence variations.

TL;DR: Anti-PD-1 antibody produced objective responses in approximately one in four to one in five patients with non-small-cell lung cancer, melanoma, or renal-cell cancer; the adverse-event profile does not appear to preclude its use.

The blockade of immune checkpoints in cancer immunotherapy
TL;DR: Preliminary clinical findings with blockers of additional immune-checkpoint proteins, such as programmed cell death protein 1 (PD1), indicate broad and diverse opportunities to enhance antitumour immunity with the potential to produce durable clinical responses.
