ABCC1 transporter exports the immunostimulatory cyclic dinucleotide cGAMP

JH Maltbaek, S Cambier, JM Snyder, DB Stetson - Immunity, 2022 - cell.com
The DNA sensor cyclic GMP-AMP synthase (cGAS) is important for antiviral and anti-tumor
immunity. cGAS generates cyclic GMP-AMP (cGAMP), a diffusible cyclic dinucleotide that …

Human DNA-PK activates a STING-independent DNA sensing pathway

K Burleigh, JH Maltbaek, S Cambier, R Green… - Science …, 2020 - science.org
Detection of intracellular DNA by the cGAS-STING pathway activates a type I interferon-mediated
innate immune response that protects from virus infection. Whether there are additional …

PD-1/PD-L1 blockade enhances T-cell activity and antitumor efficacy of imatinib in gastrointestinal stromal tumors

…, MJ Beckman, BD Medina, JH Maltbaek… - Clinical Cancer …, 2017 - AACR
Purpose: Tyrosine kinase inhibitors are effective in gastrointestinal stromal tumors (GISTs)
but often are of transient benefit as resistance commonly develops. Immunotherapy, …

Macrophages and CD8+ T Cells Mediate the Antitumor Efficacy of Combined CD40 Ligation and Imatinib Therapy in Gastrointestinal Stromal Tumors

…, JK Loo, J Santamaria-Barria, JH Maltbaek… - Cancer immunology …, 2018 - AACR
Tyrosine kinase inhibition of gastrointestinal stromal tumors (GIST) is effective but typically
culminates in resistance and is rarely curative. Immunotherapy has potential application to …

Wnt/β-catenin signaling contributes to tumor malignancy and is targetable in gastrointestinal stromal tumor

…, F Rossi, MH Crawley, JK Loo, JH Maltbaek… - Molecular cancer …, 2017 - AACR
Gastrointestinal stromal tumor (GIST) is the most common type of sarcoma and usually harbors
either a KIT or PDGFRA mutation. However, the molecular basis for tumor malignancy is …

Oncogenic kinase inhibition limits Batf3-dependent dendritic cell development and antitumor immunity

…, MJ Cavnar, JK Loo, NJ Param, JH Maltbaek… - Journal of Experimental …, 2019 - rupress.org
Gastrointestinal stromal tumor (GIST) is driven by an activating mutation in the KIT proto-oncogene.
Using a mouse model of GIST and human specimens, we show that intratumoral …

The V654A second-site KIT mutation increases tumor oncogenesis and STAT activation in a mouse model of gastrointestinal stromal tumor

…, AM Seifert, BD Medina, NJ Param, JH Maltbaek… - Oncogene, 2020 - nature.com
Gastrointestinal stromal tumor (GIST) is the most common human sarcoma and arises in the
gastrointestinal tract. Most GISTs are caused by activating mutations in the KIT receptor …

[HTML][HTML] Csf1r or Mer inhibition delays liver regeneration via suppression of Kupffer cells

…, MH Crawley, BL Green, JK Loo, JH Maltbaek… - PloS one, 2019 - journals.plos.org
Introduction Murine Kupffer cells (KCs) comprise CD11b hi and F4/80 hi subsets. Tissue-resident
macrophages are known to express the tyrosine kinase receptors colony-stimulating …

ABCC1/MRP1 exports cGAMP and modulates cGAS-dependent immunity

JH Maltbaek, JM Snyder, DB Stetson - bioRxiv, 2021 - biorxiv.org
The DNA sensor cyclic GMP-AMP synthase (cGAS) is important for antiviral and anti-tumor
immunity. cGAS generates cyclic GMP-AMP (cGAMP), a diffusible cyclic dinucleotide that …
