Peripheral blood samples were collected from both groups, and isolated monocytes were subjected to transcriptome sequencing and bioinformatic analysis. The relevant genes were confirmed through quantitative polymerase chain reaction. The diagnostic value of these genes in adolescent PTB patients was analysed using receiver operating characteristic curves. Furthermore, an in vitro model was constructed by infecting THP-1 cells with the &lt;em&gt;Mycobacterium tuberculosis&lt;/em&gt; strain H37Ra to assess whether the in vitro expression levels of the identified genes were consistent with those of the genes in the peripheral blood monocytes of adolescents with PTB. The specific mechanisms were explored using methods such as lentiviral infection, flow cytometry, immunofluorescence, Western blotting, and qRT‒PCR.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The results revealed that the expression level of the &lt;em&gt;myotubularin-related protein 4&lt;/em&gt; gene (&lt;em&gt;MTMR4&lt;/em&gt;) was lower in the case group than in the control group (&lt;em&gt;P&lt;/em&gt; &lt; 0.0001; area under the curve: 0.946; 95 % confidence interval: 0.893–0.999; cut-off value: 0.844; sensitivity: 0.875; specificity: 0.969).

Multiple logistic regression and the area under the receiver operator characteristics curve (AUC) were used to evaluate the diagnostic accuracy of biomarkers, which showed significant differences between the 2 groups.

General discriminant analysis further identified Fractalkine, VEGF, GM-CSF, IL-23, and IL-1α as the top five most effective biomarkers for combinations.
