Significantly higher frequency of R/R genotype of FCGR2A p.R131H was observed in DEN cases with thrombocytopenia (TP) while the G/G genotype of CCL2 c.-2518 A > G was observed only in DEN cases with TP (p < 0.005).
This study was aimed at evaluating the expression of the CC-chemokines MIP-1α/CCL3 and MCP-1/CCL2 in peripheral blood leukocytes using an ex vivo model resembling dengue infection in vivo, in subjects with a well characterized dengue immune background, due to the exceptional Cuban epidemiological situation in dengue.
