英文摘要
Anemia, granulocytopenia, lymphopenia, and thrombocytopenia are
common in HIV infection thought their pathogenesis is not well
understood. Bone marrow hypoproliferation (ineffective hematopoiesis)
is likely to be a main contributor to the etiology of these
hematologic aberrations, and may be due to stem cell infection, or
stromal cell infection with loss of a satisfactory microenvironment to
support bone marrow growth. This growth is a complex process
requiring primary and secondary colony stimulating factors, nutrients,
and cell:cell contact. In addition, toxic, inhibitory, and immune
factors must not be present if optimal hematopoiesis is expected. In
studies of SIV infected rhesus macaques, we have described peripheral
blood cytopenias, stage-related CFU-GM and BFU-E hypoproliferation,
and absence of infection in CD34+ progenitors, partial restoration of
CFU growth with high doses of IL-3 and GM-CSF, and the presence of an
inhibitor of rhesus bone marrow secr eted by H IV-infected H9 cells.
These data show the similarity of SIV-infected monkeys to HIV-infected
humans, suggest that ineffective hematopoiesis, with cytokinetic and
possibly inhibitory abnormalities, is a factor and support the use of
this model for studying the effects of cytokine administration. We
propose a comprehensive study of the hematologic and virologic
consequences of exogenous cytokine administration in rhesus macaques
experimentally infected with SIV. We will study effects of
exogenously administered cytokines on hematopoietic compartment
expansion, sites of cellular infection, and viral replication and
burden following cytokine administration. We will utilize compartment
specific cytokines, tested in monkeys infected with a lymphocyte or a
monocyte predominant SIV strain. It is expected that, through these
aims, the positive effects of cytokines in SIV-infected macaques can
be demonstrated, any untoward effects of cytokines on viral
replication can be elucidated, and a m odel can be characterized for
future cytokine, bone marrow transportation, and gene therapy
experiments. The studies in this project represent multidisciplinary
collaboration among investigators with expertise in hematopoietic,
immunologic, and virologic aspects of SIV infection and cytokine use
in animal models. FUNDING NHLBI / R01HL55176-04 $277,927 8/01/95 -
