Fig. 8From: Immune infiltration landscape and immune-marker molecular typing of pulmonary fibrosis with pulmonary hypertensionScreening of hub genes related to immune cell infiltration. A The protein–protein interaction network constructed using the genes from the green module in the STRING database. The greater the redness of the point, the larger the size, indicating that the node has more genes. B Identification of the key genes of the green module. The hub gene is indicated by the red box. C Intersection of hub genes identified from the green module and key nodes in PPI network to produce a single set of 5 critical genes associated with immune cell infiltration in APHBack to article page
