D. Brugnoni et al., CD3(-)CD4(-LIKE PATTERN OF CYTOKINE PRODUCTION IN THE PERIPHERAL-BLOOD OF A PATIENT WITH CUTANEOUS T-CELL LYMPHOMA() CELLS WITH A TH2), Leukemia, 11(11), 1997, pp. 1983-1985
A case of cutaneous T cell lymphoma associated with mild eosinophilia
and rise of IgE levels is reported. A population of CD3(-)CD4(+) cells
was observed in the peripheral blood. After activation, these purifie
d CD3(-)CD4(+) cells showed a Th2 pattern of cytokine production, secr
eting higher levels of IL-5 and IL-4 and lower levels of IFN-gamma com
pared to the patient's and controls' CD3(+)CD4(+) cells. Moreover, hig
h levels of IL-5 and soluble CD30, a marker of Th2 cell activation, we
re detected in the patient's serum.
