Published: April 2018

Innate lymphocytes play critical roles in maintaining tissue homeostasis and integrity of the host at steady state and during pathogenic insults. The successive identification of new innate lymphocyte subsets has revealed an incredible diversity within the family. While this heterogeneous population can be grouped based on their cytotoxic potential into exclusively cytokine-producing helpers and cytolytic killers, the exact developmental relationships between the subsets are not fully understood. The former group is enriched at mucosal surfaces, whereas innate lymphocytes with cytotoxic potential can be identified in a wider array of tissues, including tumors. Although their cytotoxicity suggests an antitumor role, the nature of tumor-elicited innate lymphocyte responses has only begun to be investigated, and the identities of participating subsets still remain contentious. In this review, we provide a brief overview of innate lymphocyte biology, review the current knowledge on their ontogeny, and discuss their roles in tumor immunosurveillance. .

Volume-regulated anion channels (VRACs) are heteromeric complexes formed by proteins of the leucine-rich repeat-containing 8 (LRRC8) family. LRRC8A (also known as SWELL1) is the core subunit required for VRAC function, and it must combine with one or more of the other paralogues (i.e.

The lung tumor microenvironment (TME) or stroma is a dynamic space of numerous cells and their released molecules. This complicated web regulates tumor progression and resistance to different modalities. Lung cancer cells in conjunction with their stroma liberate a wide range of factors that dampen antitumor attacks by innate immunity cells like natural killer (NK) cells and also adaptive responses by effector T cells.

The underlying mechanisms used by the intestinal microbiota to shape disease outcomes of the host are poorly understood. Here, we show that the gut commensal protozoan, Tritrichomonas musculis (T.mu), remotely shapes the lung immune landscape to facilitate perivascular shielding of the airways by eosinophils.

Viral mimicry driven by endogenous double-stranded RNA (dsRNA) stimulates innate and adaptive immune responses. However, the mechanisms that regulate dsRNA-forming transcripts during cancer therapy remain unclear. Here, we demonstrate that dsRNA is significantly accumulated in cancer cells following pharmacologic induction of micronuclei, stimulating mitochondrial antiviral signaling (MAVS)-mediated dsRNA sensing in conjunction with the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway.
