Welcome to the final JITC digest of 2021. This past year has
not been without its challenges, but the immunotherapy field has also
seen tremendous advancement. Checkpoint inhibitors are moving into the
standard of care for an ever increasing number of tumor types as well as
in earlier stages of disease and the number of approved CAR T cell
products has more than doubled in the past year alone.
The journal has also progressed by leaps and bounds this year, and the more than three-point bump in JITC’s
impact factor in 2021 reflects the high quality of research found in
every issue. As the journal continues to grow and excel, I am excited to
announce that James L. Gulley MD, PhD, FACP, has been appointed to the
role of Deputy Editor-in-Chief. Be sure to read this month’s special
feature for a biography of JITC’s new second-in-command and the extensive experience he brings to the role.
For the final digest of the year, we are highlighting four exemplary
original research articles that offer innovative approaches for
modulation of the tumor microenvironment.
Intratumoral immunotherapy is the focus of Yu-Chao Zhu and colleagues and Maite Alvarez et al. The first group demonstrate feasibility of intratumoral administration of an attenuated strain of the protozoan parasite Toxoplasma gondii
leading to tumor rejection and immune memory. The second manuscript
shows synergistic activity of a poly I:C derivative and a STING agonist
even when injected into separate lesions.
New mechanistic insight into mechanisms of immune evasion are also
offered. Inhibition of dipeptidyl peptidase is identified as a strategy
to enhance efficacy of anti-PD-1 against the immunologically cold tumor
pancreatic ductal adenocarcinoma by Allison A. Fitzgerald et al.
A new soluble immune checkpoint, chitinase 3-like-1, is revealed as an
inhibitor of natural killer (NK) cell antibody-dependent cellular
cytotoxicity by Abbass Darwich and colleagues.
