我们建议继续研究T细胞淋巴瘤的生物学,
AKR小鼠。 总体目标是更好地了解
病毒和细胞的相互作用发生在这种小鼠品系,
产生胸腺淋巴瘤。 该计划是建立在过去的观察,
这个实验室和其他实验室,并提出了三个创新的方法。
首先,我们已经证明了骨髓中的前淋巴瘤细胞。 这些
细胞不能自主生长,但它们会变成淋巴瘤细胞
在它们迁移到胸腺后。 我们将研究这些基因的表型
细胞 将尝试在体外培养它们。 将确定
如果体外感染克隆的AKR淋巴瘤病毒可以导致

英文摘要
We propose to continue our studies of the biology of the T cell lymphoma in
AKR mice. The overall aim is to develop a better understanding of the
viral and cellular interactions which take place in this mouse strain to
produce thymic lymphoma. The program is built on past observations from
this and other laboratories and proposes three innovative approaches.
First, we have demonstrated prelymphoma cells in the bone marrow. These
cells are not capable of autonomous growth but they become lymphoma cells
after they migrate to the thymus. We will study the phenotype of these
cells. Attempts will be made to grow them in vitro. It will be determined
if in vitro infection with cloned AKR lymphomagenic viruses can result in
the expression of prelymphoma cells. A second part of this proposal will
be to study the in vivo spread of lyphomagenic viruses in the tissues of
'virus free' strains of mice (CBA/H and NFS). Certain cloned isolates of
the AKR viruses which are lymphoma-accelerating for the AKR strain induce
thymic lymphoma in these two strains while others do not, thus, making a
comparison of the organ (tissue) expression of these viruses of interest.
In the third part of the proposal, we will study lymphoma cell lines for
their sensitivity or resistance to corticosteroids. Steroid sensitive and
resistant clones have been isolated from a parent AKR lymphoma cell line.
The resistant cell line containing normal numbers of hormone receptors
appears to result from an in vitro differentiation of the hormone sensitive
cells. We wish to determine if resistant cells lines can be derived after
in vivo inoculation of the sensitive lines and to study the in vivo growth
properties of these lines. These two cell lines will also be used for a
new experimental approach to molecularly clone the genes for steroid
induced lysis which vary in their expression at different stages of T cell
differentiation.
