Adjuvant activity of type I interferons

bchm, 2008
AbstractType I interferons (IFNs) produced primarily by plasmacytoid dendritic cells (pDCs) as part of the innate immune response to infectious agents induce the maturation of myeloid DCs and enhance antigen presentation. Type I IFNs also enhance apoptosis of virus-infected cells, stimulate cross priming and enhanced presentation of viral peptides ...

A type I IFN-dependent DNA damage response regulates the genetic program and inflammasome activation in macrophages [PDF]

, 2017
Macrophages produce genotoxic agents, such as reactive oxygen and nitrogen species, that kill invading pathogens. Here we show that these agents activate the DNA damage response (DDR) kinases ATM and DNA-PKcs through the generation of double stranded ...

Type I interferon response drives neuroinflammation and synapse loss in Alzheimer disease.

Journal of Clinical Investigation, 2020
Type I interferon (IFN) is a key cytokine that curbs viral infection and cell malignancy. Previously, we have demonstrated a potent IFN immunogenicity of nucleic acid (NA)-containing amyloid fibrils in the periphery.

TREX1, a predator for treating MSI‐H tumors?

Molecular Oncology, EarlyView.
Immunotherapy benefits many patients; yet, some with MSI‐H tumors remain unresponsive despite their high immunogenicity. Xu et al. reveal that TREX1 enables immune evasion by degrading cytosolic DNA and suppressing cGAS–STING–IFN‐I signaling. TREX1 loss restores DNA sensing, increases CD8+ T and NK cell infiltration, and boosts antitumor immunity ...

Peripheral inflammation is associated with remote global gene expression changes in the brain [PDF]

, 2014
Background: Although the central nervous system (CNS) was once considered an immunologically privileged site, in recent years it has become increasingly evident that cross talk between the immune system and the CNS does occur. As a result, patients with

Dysregulation of type I interferon responses in COVID-19

Nature reviews. Immunology, 2020
Infection with SARS-CoV-2 can lead to excessive production of pro-inflammatory cytokines, but the production of type I interferons, which are key antiviral mediators, is reportedly blunted.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

STING-Mediated IFI16 Degradation Negatively Controls Type I Interferon Production

Cell Reports, 2019
Summary: γ-interferon-inducible protein-16 (IFI16), a key DNA sensor, triggers downstream STING-dependent type I interferon (IFN-I) production and antiviral immunity.

An unbiased genetic screen reveals the polygenic nature of the influenza virus anti-interferon response. [PDF]

, 2014
Influenza A viruses counteract the cellular innate immune response at several steps, including blocking RIG I-dependent activation of interferon (IFN) transcription, interferon (IFN)-dependent upregulation of IFN-stimulated genes (ISGs), and the activity

Combining antibody conjugates with cytotoxic and immune‐stimulating payloads maximizes anti‐cancer activity

Molecular Oncology, EarlyView.
Methods to improve antibody–drug conjugate (ADC) treatment durability in cancer therapy are needed. We utilized ADCs and immune‐stimulating antibody conjugates (ISACs), which are made from two non‐competitive antibodies, to enhance the entry of toxic payloads into cancer cells and deliver immunostimulatory agents into immune cells.
