This study integrates necroptosis-related gene expression with immune landscape analysis using the GSE33000 dataset, then applies consensus clustering to group samples into two necroptosis clusters with distinct immune signatures and pathway enrichments. Key genes are derived through weighted gene co-expression network analysis, intersected with Alzheimer’s disease-relevant genes, and used to compare four machine learning classification strategies. Extreme gradient boosting yields the most reliable diagnostic performance, supported by nomogram, calibration, decision curve analysis, and external validation, highlighting five informative variables linked to Alzheimer’s pathological features.","TYPE Original Research PUBLISHED 20 September 2023 DOI 10.3389/fnagi.2023.1249682  \nOPEN ACCESS  \nEDITED BY  \nVijaykumar Muley,  \nNational Autonomous University of Mexico, Mexico  \nREVIEWED BY  \nHan She,  \nArmy Medical University, China Jinchao Hou,  \nWashington University in St. Louis, United States  \n*CORRESPONDENCE  \nYulin Yuan  \n [yuanyulin202301@163.com](yuanyulin202301@163.com)[ ](yuanyulin202301@163.com)Lichuan Lai  \n [michaellailichuan@163.com](michaellailichuan@163.com)  \n†These authors have contributed equally to this work  \nRECEIVED 29 June 2023  \nACCEPTED 30 August 2023  \nPUBLISHED 20 September 2023  \nCITATION  \nWei H, Wu C, Yuan Y and Lai L (2023)  \nUncovering the Achilles heel of genetic heterogeneity: machine learning-based classification and immunological properties of necroptosis clusters in Alzheimer’s disease.

Necroptosis is a common type of programmed cell death that has been shown to be activated in AD.  \nMethods: In this study, we first investigated the expression profiles of necroptosisrelated genes (NRGs) and the immune landscape of AD based on GSE33000 dataset. Next, the AD samples in the GSE33000 dataset were extracted and subjected to consensus clustering based upon the differentially expressed NRGs. Key genes associated with necroptosis clusters were identified using Weighted Gene Co-Expression Network Analysis (WGCNA) algorithm, and then intersected with the key gene related to AD. Finally, we developed a diagnostic model for AD by comparing four different machine learning approaches. The discrimination performance and clinical relevance of the diagnostic model were assessed using various evaluation metrics, including the nomogram, calibration plot, decision curve analysis (DCA), and independent validation datasets.  \nResults: Aberrant expression patterns of NRGs and specific immune landscape were identified in the AD samples. Consensus clustering revealed that patients in the GSE33000 dataset could be classified into two necroptosis clusters, each with distinct immune landscapes and enriched pathways. The Extreme Gradient Boosting (XGB) was found to be the most optimal diagnostic model for the AD based on the predictive ability and reliability of the models constructed by four machine learning approaches. The five most important variables, including ACAA2, BHLHB4, CACNA2D3, NRN1, and TAC1, were used to construct a fivegene diagnostic model. The constructed nomogram, calibration plot, DCA, and external independent validation datasets exhibited outstanding diagnostic performance for AD and were closely related with the pathologic hallmarks of AD.  \nConclusion: This work presents a novel diagn","cbCaid2qIIdTMJwL","https://ap.wps.com/l/cbCaid2qIIdTMJwL","pdf",13460689,1,15,"English","en",105,"# Introduction\n# Methods\n## Data and gene
