Background: Monocytes play an important role in immune and inflammatory diseases and monocyte subsets are\npredictors of disease in certain conditions. Expression of the chemokine receptors, CCR2 and CX3CR1 on monocyte\nsubsets relates to their function and can be used in their characterization. Our objective was to determine whether\nCD14, CD16, CCR2 and CX3CR1 on monocyte subsets are potential indicators of asthma severity.\nMethods: Blood samples were collected from Saudi Arabian patients with asthma and normal healthy individuals.\nSix-color flow-cytometry phenotypic analysis was used to identify human blood monocyte subsets, based on their\nexpression of CD14 and CD16 following CD45 gating............................
