The expression of TCR-gamma delta/CD3 complex in neoplastic gamma delta T-cell.

We describe that the neoplastic gammadelta T-cells from patients with hepatosplenic gammadelta T-cell lymphoma have a lower expression of TCR-gammadelta/CD3 complex compared to their normal or reactive counterparts. Interestingly, with the use of an appropriate antibody association, this feature is easily and rapidly observed on flow cytometry graphics.
