(exbio.cz)
The captured basophils were activated using an anti-FceRI antibody and the basophil identification marker CD203c and the activation marker CD63 were detected using fluorescence microscopy. (kth.se)
Basophils did not upregulate CD63 after passage through a microfluidic chip, but there was a slight but significant activation after crosslinking of CD203c, which is the surface marker used for basophil-specific capture in miBAT, giving one potential factor for the background activation. (kth.se)
IgE-dependent (anti-IgE) basophil degranulation after crosslinking of adhesion molecules, to mimic adhesion before transmigration into tissue, showed a significant decrease in CD63-expression compared to anti-IgE activation, which indicate a regulatory function. (kth.se)
Cytokine stimulation followed by IgE-independent (fMLP) basophil degranulation on the other hand showed a significantly increased CD63-expression compared to non-primed fMLP activation. (kth.se)
In conclusion, we have developed a novel microfluidic-based technique (miBAT) able to detect basophil activation (CD63-expression) using allergens in allergic patients. (kth.se)
