Fluorescent labeled monoclonal antibodies (mAbs) against CD36 are routinely used as monocyte, erythroid, or platelet markers in clinical cytometry. CD36 has recently been proposed by various authors as a valuable marker helping to enumerate leukocyte's subpopulations by flow cytometry. However, it is known that binding of CD36 may induce platelet activation and formation of platelet's rosettes on leukocytes, resulting in false expression of platelet markers on white blood cells. To study this phenomenon, we have combined classical flow cytometry and a new quantitative flow imaging technique with the ImageStream(®) analyzer. We show that CD36 ligation induces activation of platelets with CD62 expression and their adhesion on leukocytes due to CD62 and CD162 interactions. Preincubation of whole blood samples with either anti-CD62 or anti-CD162 antibodies could prevent formation of these rosettes. Our approach also emphasizes the fact that immunomorphological analysis of cell events with ImageStream technology is a useful tool to validate the specificity of marker's labeling or to elucidate incoherent results obtained with classical flow cytometry. We thus propose to prevent false platelet labeling on leukocytes by preincubation with either anti-CD62 or anti-CD162 antibodies when using CD36 mAbs.
