    Abstract

    Chemokines represent central players of the innate and adaptive immunity and are involved in the regulation of inflammatory events occurring during infectious complications or during graft vs. host disease (GvHD). Patients after allogeneic stem cell transplantation (alloSCT) are at a high risk for the development of acute GvHD or to suffer from fungal infections. Susceptibility to fungal infections and the course of GvHD can be genetically influenced by single nucleotide polymorphisms (SNPs), which regulate expression or biological activity of chemokines, and therefore have an impact on the outcome of invasive aspergillosis and GvHD. High lightened studies of abetting factors for GvHD revealed SNPs in TNFA, IL-6, IL-10, INF-γ, CCL2, CCL5 (RANTES), IL-1Ra, IL-23R, IL-7Ralpha, IL-10RB, and CCR9 genes as prevalent considerable. Furthermore, additional SNPs were described to be significantly associated with fungal infections (Aspergillus fumigatus, Candida albicans), including markers in CCL3, CCL4, CCL20, CXCL2, CXCL8, CXCL10, CCR1, and CCR2. This review summarizes the current knowledge about the growing number of genetic markers in chemokine genes and their relevance for patients after alloSCT.
