Release of Highly-Sulphated Glycosaminoglycans and Histamine from Human Basophils

A new assay for highly-sulphated glycosaminoglycans (GAGs) has been applied to the study of allergen &lt;i&gt;(Dermatophagoides pteronyssinus)&lt;/i&gt;-induced release of GAG from human basophils. Highly-sulphated GAG, which was not heparin, was found only in basophil-containing cellular fractions of whole blood. Its release, like that of histamine, was Ca&lt;sup&gt;++&lt;/sup&gt;-dependent. However, allergen-induced release of GAG from the basophils of atopic individuals exhibited a different time-course and dose-response from that of histamine, and may occur at least in part by a different mechanism.</jats:p

Circulating Basophil Counts in Atopic Individuals

Absolute numbers of circulating basophils were measured in 55 atopic and 35 non-atopic individuals, using a flow cytometer for automated cell counting. They were significantly elevated in the atopic group (p &lt; 0.001), but the total leucocyte count was not significantly different between the two groups. Eosinophil counts, which correlated with the number of basophils for both populations, were also significantly raised in the atopic group (p &lt; 0.001). Individual variation in absolute basophil counts was not detected in sequential samples taken at daily intervals over 5 days, in 5 atopies and 4 non-atopies. In addition, no significant variation was detected in 6 atopies and 5 non-atopies over a period of up to 20 months.</jats:p
