CXCR1 and dengue disease: The up-regulation of CXCR1, and IL18RAP in the severe progression of dengue, coupled with associated DE-HERVs, and an additional regulatory layer with miRNA and non-LTR retroviruses suggests a complex role of these genes in intensified inflammatory response that may further exacerbate vascular leakage and immune-mediated tissue damage, underlining their roles in immune modulation, possibly contributing to the severe progression of dengue.
