C. Coutton et Jc. Chermann, IN-VITRO STUDY OF SERASPENIDE ON HIV-INDUCED INHIBITION OF GRANULOPOIESIS, European journal of haematology, 59(3), 1997, pp. 184-189
Soluble(s) factor(s) produced by HIV-infected cells have been implicat
ed in bone marrow dysfunction observed in AIDS patients. We have shown
previously that infected macrophage but not CBMC-derived conditioned
medium inhibited the differentiation of purified CD34(+) cells. sugges
ting that accessory cells play a crucial role in granulopoiesis inhibi
tion induced indirectly by HIV. In order to prevent this inhibition we
tested the potential protective effect of Seraspenide, a reversible i
nhibitor of hematopoietic progenitors. We showed that 20 h pretreatmen
t of mononuclear cells with Seraspenide at 10(-10) mol/l prevents CFU-
GM inhibition induced by HIV-infected cell-derived conditioned medium.
