examination of the most likely precursor of langerhans cells , the blood monocytes , indicated an increase of monocyte counts in type 1 diabetic patients after 6 months duration ( 344 +/- 37 cells/microliters vs 191 +/- 31 in control subjects , p less than 0.05 ) and an inverse correlation between the number of langerhans cells in skin with the number of monocytes in peripheral blood ( at onset : r = -0.73 , p less than 0.01 , after 6 months of diabetes : r = -0.61 , p less than 0.05 ) .
