Score: 4/10 | Pathways: NLRP3, VDAC1, mTOR-lysosomal, clinical-phenotype, other

The paper touches on NLRP3 inflammasome activation, mitochondrial dysfunction, and bile acid dysregulation in a hepatic context that is tangentially relevant to the family's hepatology phenotype (cholecystectomy clustering, hepatic steatosis) and the NLRP3/mitochondrial damage streams in the disease mechanism, but the focus is on drug-induced hepatotoxicity from atorvastatin rather than any intrinsic innate immune or SAMHD1-related pathway.

Neutrophil extracellular traps in atherothrombosis (from Cardiology/vascular biology)
Ming Xue; Xin Li; Songhai Li; Jing Yang — Chinese Bulletin of Life Sciences 2026
Score: 4/10 | Pathways: cGAS-STING, NLRP3, VDAC1, POLG-mtDNA, urate-NLRP3, other

The paper touches several core pathways (NLRP3 inflammasome, cGAS-STING via mtDNA release, mitochondrial dysfunction) as drivers of NETosis in atherosclerosis, which are mechanistically relevant to the SAMHD1 interferonopathy framework, but the primary subject is NETs in cardiovascular disease and there is no direct connection to SAMHD1, haploinsufficiency, or the specific family phenotype.

Regulated cell death: a multidimensional regulatory network in the pathogenesis of renal fibrosis. (from Nephrology)
Li Wen; Zhou Liang; Zhang Jinji; Sun Jingying; Feng Qing — 2026
Score: 3/10 | Pathways: NLRP3, mTOR-lysosomal, other

This review covers pyroptosis/NLRP3 and autophagy in renal fibrosis context, which are mechanistically relevant pathways in the disease model, but the organ focus (kidney fibrosis) and disease context (renal pathology) are not part of the family phenotype profile, making the connection largely tangential.

ASS1 Promotes Atherosclerotic Inflammation Through the NLRP3/IL-33/ST2 Axis in Ox-LDL–Induced Foam Cells (from Cardiology/Vascular Biology)
Shaoyu Wu; Feihuang Han; Z. Qiao; S. Yuan; Xiaohui Bian — Frontiers in Bioscience-Landmark 2026
Score: 3/10 | Pathways: NLRP3, other

The paper examines NLRP3 inflammasome activation in foam cells via ASS1/STAT3/IL-33, which shares the NLRP3 node with the SAMHD1 disease mechanism, but the upstream driver (ox-LDL/argininosuccinate metabolism in atherosclerosis) is entirely distinct from the dGTP/urate/mtDNA-driven NLRP3 activation in SAMHD1 haploinsufficiency, with no mechanistic overlap in cGAS-STING, VDAC1, ISG15, or mitochondrial dNTP pathways.

Oxidative Stress and Inflammatory Pathways in Male Infertility: Molecular Mechanisms and Therapeutic Strategies (from andrology/reproductive medicine)
R. Zhankina; N. Tanideh; A. Botabayeva; U. Zhanbyrbekuly — West Kazakhstan Biomedicine Journal 2026
Score: 3/10 | Pathways: NLRP3, other

The paper discusses NLRP3 inflammasome activation and mitochondrial ROS in a reproductive context, which shares surface mechanistic overlap with the NLRP3 and mitochondrial dysfunction arms of the SAMHD1 pathomechanism, but the connection is entirely tangential — it does not address SAMHD1, cGAS-STING, interferonopathy, dNTP pool dysregulation, or any of the core molecular players, and male infertility is not a documented family phenotype.

Precision Neurodegeneration: Integrating Molecular Mechanisms, Biomarkers, and Targeted Therapeutics. (from Neurology/neurodegeneration)
Guizhen Lyu; Dongbing Li — CNS & neurological disorders drug targets 2026
Score: 3/10 | Pathways: NLRP3, ISG15-mitophagy, mTOR-lysosomal

While the paper mentions NLRP3 inflammasome and PINK1-Parkin mitophagy as therapeutic nodes in neurodegeneration, these are discussed in the generic context of Alzheimer's/Parkinson's disease without any mechanistic connection to SAMHD1, interferonopathy, cGAS-STING, or the dNTP pool dysregulation central to the disease profile.

The IFIT3 Protein of Porcine Induces Interferon Signaling and Inhibits the Early Gene Expression of African Swine Fever Virus (from veterinary virology)
Wen-Li Wang; Deng-Wu Han; Xing Yang; Xijuan Shi; Yesheng Shen — Viruses 2026
Score: 3/10 | Pathways: JAK-STAT, ISG15-mitophagy, other

This paper characterizes porcine IFIT3 (ISG60) as an antiviral ISG acting through STAT1/TBK1/IRF3 and JAK-STAT signaling, touching on ISG15 and IRF3 which are nodes in the disease mechanism, but the work is focused on ASFV restriction in swine macrophages with no direct relevance to SAMHD1, human interferonopathy, mitochondrial dysfunction, or the family's clinical phenotypes.

Abstract C043: Novel insights into the immunoregulatory role of radiation activated club cells in non-small cell lung cancer (from Radiation oncology / lung cancer immunology)
Aakanksha R Kapoor; Arshdeep Singh; Bharati Swami; Yongfeng He; Vivek Mittal — Cancer Immunology Research 2026
Score: 3/10 | Pathways: JAK-STAT, ISG15-mitophagy, other

While the paper documents radiation-induced Type I interferon/ISG15/STAT1 upregulation in lung club cells — pathways central to the SAMHD1 interferonopathy mechanism — the context is entirely radiation-oncology/NSCLC tumor microenvironment with no connection to SAMHD1, dNTPase biology, mitochondrial dysfunction, or the family's clinical phenotype.

Nucleotide metabolism reprogramming in obesity-associated cardiovascular inflammation: a new perspective (from Cardiology/Immunometabolism)
Taoming Qian; Mei Zhang; Yuhan Liu; Donghao Guo; Juan Jin — Frontiers in Immunology 2026
Score: 9/10 | Pathways: dNTPase, NLRP3, POLG-mtDNA, urate-NLRP3, treatment-target, clinical-phenotype, other

This paper directly models the SAMHD1-inhibition → cytosolic dNTP accumulation → mitochondrial dNTP import (SLC25/PNC transporters) → mtDNA oxidation → NLRP3 hyperactivation axis that is the PURPLE stream of the disease mechanism, proposes therapeutic nodes at SLC25 inhibition and SAMHD1-preserving kinase modulation, and validates the mechanistic framework in a cardiovascular/macrophage context highly relevant to the family's cardiac and inflammatory phenotypes.

Nickel exposure promotes aortic dissection progression by binding to VDAC1 and activating the cGAS-STING pathway in vascular smooth muscle cells. (from Cardiology/Vascular Surgery)
Xiao Zhihao; Jin Jing; Long Xiangxing; Zhu Xu; Jiao Jian — 2026
Score: 8/10 | Pathways: cGAS-STING, VDAC1, NLRP3, treatment-target, other

This paper directly demonstrates the VDAC1 oligomerization → mtDNA leakage → cGAS-STING activation axis in a cardiovascular cell type, mechanistically validating the BLUE stream of the SAMHD1 haploinsufficiency model, and identifies VBIT-12 (closely related to VBIT-4, a key treatment target in this disease) as an inhibitor of this pathway, providing direct mechanistic and therapeutic relevance.

SETD2 Deficiency Drives Mitochondrial DNA Leakage and Creates a Druggable Dependency on BCL-XL in Clear Cell Renal Cell Carcinoma. (from Oncology (clear cell renal cell carcinoma / tumor suppressor biology))
Uprety Anusha; Judd Chandler; Villella Emily D; Keller Rebecca; Wagner Ryan — 2026
Score: 7/10 | Pathways: cGAS-STING, VDAC1, BIK-cancer, POLG-mtDNA, treatment-target

This paper directly demonstrates the mechanistic link between cytoplasmic mtDNA leakage → cGAS-STING activation → IRF3 → apoptotic priming via BH3-only proteins (NOXA/MCL-1/BCL-xL), which parallels the BLUE and RED streams of the SAMHD1 A565T mechanism (VDAC1 macropore → mtDNA escape → cGAS-STING → IRF3), and also engages the BIK-cancer axis relevant to the family's solid tumor phenotypes, while introducing BCL-xL as a druggable synthetic lethal node downstream of chronic innate immune mtDNA sensing.

ATP-Responsive Bimetallic Metal-Organic Frameworks Amplify Oxidative Stress in the Tumor Microenvironment for Synergistic Chemo-Immunotherapy. (from Oncology/Nanomedicine)
Li You; Zhang Wenxin; Xu Zitao; Ma Shixin; Xiong Yufei — 2026
Score: 5/10 | Pathways: cGAS-STING, VDAC1, POLG-mtDNA, other

This paper mechanistically demonstrates that Zn2+-induced mitochondrial dysfunction causes mtDNA leakage into the cytosol, activating cGAS-STING signaling—a core pathway in the SAMHD1 haploinsufficiency mechanism (BLUE stream via VDAC1 macropore → cytosolic mtDNA → cGAS → STING → IFN-I), but the context is entirely tumor-focused nanomedicine with no connection to SAMHD1, interferonopathy, or the family phenotype.

GE11/RGD Dual-Ligand Copper Nanoassemblies Synchronize Cuproptosis and Photothermal Therapy for Targeted Cervical Cancer Ablation. (from Oncology/nanomedicine)
Yang Nan; Liu Lu; Ding Lu; Chen Zhen; Su Tianyuan — 2026
Score: 4/10 | Pathways: cGAS-STING, POLG-mtDNA, other

The paper demonstrates that mtDNA leakage from mitochondrial collapse activates the cGAS-STING-IRF3 pathway as an anti-tumor mechanism, which is mechanistically relevant to the BLUE stream of the disease model, but in the context of copper-induced cuproptosis in cervical cancer with no connection to SAMHD1, interferonopathy, or the family phenotype.
