A Predictive Disease Risk Model for Ankylosing Spondylitis: Based on Integrated Bioinformatic Analysis and Identification of Potential Biomarkers Most Related to Immunity

Figure 6

Analysis of the correlations of significantly expressed genes with immune cells and immunological functions. The darker the red colour is, the higher the value and the stronger the positive correlation were, and vice versa, the lighter the red colour is, the weaker the positive correlation was. In contrast, the darker the purple colour is, the higher the value and the stronger the negative correlation were, and vice versa, the lighter the purple colour is, the weaker the negative correlation was. NK cells and T cell coinhibition were strongly correlated with the significantly expressed genes. CD8⁺ T cells and Th1 cells were strongly correlated with the significantly expressed genes.
