Despite growing recognition of the role of innate immunity in MDS pathogenesis, the precise mechanisms remain unclear. In this study, we analyzed bone marrow CD34+ expression data from 183 MDS patients to investigate the impact of the Toll\u2010like receptor (TLR) pathway on disease progression. Six key innate immunity genes (\n                    <jats:italic>IRAK1<\/jats:italic>\n                    ,\n                    <jats:italic>IRAK2<\/jats:italic>\n                    ,\n                    <jats:italic>IRAK4<\/jats:italic>\n                    ,\n                    <jats:italic>MYD88<\/jats:italic>\n                    ,\n                    <jats:italic>TRAF6<\/jats:italic>\n                    , and\n                    <jats:italic>NFKB1<\/jats:italic>\n                    ) were used to define two distinct immune clusters: a hyperactive immune cluster (HIC) and a moderate immune cluster (MIC). The HIC was enriched in 155 immune\u2010related pathways and showed higher infiltration of activated natural killer cells and M1 macrophages, while the MIC exhibited increased infiltration of na\u00efve B cells and mast cells. Differential expression analysis identified 35 genes that distinguished the clusters. Validation in an independent cohort of 82 patients revealed that reduced expression of these genes correlated with markers of advanced disease, including lower hemoglobin levels, lower neutrophil counts, altered\u00a0cytogenetics, and higher bone marrow blast percentages. These findings underscore the critical role of immune dysregulation in MDS progression and highlight novel therapeutic opportunities within the innate immunity pathway for tailored interventions.\n
