Expression of CD23, CD32, Mac-1 and other adhesion molecules in eosinophils in strongyloidiasis and HTLV-I-positive patients.

The relationship between human T-lymphotropic virus I (HTLV-I) infection and strongyloidiasis has recently become an important problem. This study compared the expression of CD23, CD32, Mac-1 and other adhesion molecules in eosinophils of patients with strongyloidiasis positive for anti-(HTLV-I) antibodies and in those negative for the antibodies. The expression of CD23, Mac-1 and intercellular adhesion molecule-1 (ICAM-1) on eosinophils of patients with strongyloidiasis was augmented in comparison with normal subjects and HTLV-I carriers. There were no significant differences, however, in the expression of CD23, CD32, Mac-1 and adhesion molecules (ICAM-1, leukocyte function-associated antigen-1 alpha (LFA-1 alpha), LFA-1 beta, very late antigen-4) on eosinophils of patients with strongyloidiasis positive for anti-HTLV-I antibodies in comparison with those negative for these antibodies.
