TLDR
The generation of antitumor CD8+ T cell responses requires type I interferon responsiveness in host antigen-presenting cells and the response is dominated by T-cells that secrete polypeptide A into the T cells of the immune system.Abstract:
Despite lack of tumor control in many models, spontaneous T cell priming occurs frequently in response to a growing tumor. However, the innate immune mechanisms that promote natural antitumor T cell responses are undefined. In human metastatic melanoma, there was a correlation between a type I interferon (IFN) transcriptional profile and T cell markers in metastatic tumor tissue. In mice, IFN-β was produced by CD11c+ cells after tumor implantation, and tumor-induced T cell priming was defective in mice lacking IFN-α/βR or Stat1. IFN signaling was required in the hematopoietic compartment at the level of host antigen-presenting cells, and selectively for intratumoral accumulation of CD8α+ dendritic cells, which were demonstrated to be essential using Batf3−/− mice. Thus, host type I IFNs are critical for the innate immune recognition of a growing tumor through signaling on CD8α+ DCs.read more

TL;DR: Two broad categories of tumor escape based on cellular and molecular characteristics of the tumor microenvironment are suggested, which appear to resist immune attack through immune system exclusion or ignorance and may require distinct immunotherapeutic interventions for maximal therapeutic effect.

How cells respond to interferons
TL;DR: The Janus kinases and signal transducers and activators of transcription, and many of the interferon-induced proteins, play important alternative roles in cells, raising interesting questions as to how the responses to the interFERons intersect with more general aspects of cellular physiology and how the specificity of cytokine responses is maintained.

TL;DR: The methodology for inducing dendritic cell growth that was recently described for mouse blood now has been modified to MHC class II- negative precursors in marrow, and this feature should prove useful for future molecular and clinical studies of this otherwise trace cell type.

Release of chromatin protein HMGB1 by necrotic cells triggers inflammation
TL;DR: It is reported that Hmgb1-/- necrotic cells have a greatly reduced ability to promote inflammation, which proves that the release of HMGB1 can signal the demise of a cell to its neighbours, and cells undergoing apoptosis are programmed to withhold the signal that is broadcast by cells that have been damaged or killed by trauma.
