    This patent relates to a system for the production of recombinant 
AAV vectors for gene therapy. More particularly, the patent relates to 
an AAV vector system which utilizes an inducible system for the 
production of high titer virus. The first vector contains a 5' and 3' 
AAV ITR flanking the heterologous gene of interest to be delivered. The 
second vector contains an inducible origin of replication and the AAV 
rep and cap proteins. This second vector provides a means for 
increasing the amount of AAV structural proteins available for the 
production of infectious AAV particles. In the presence of the inducing 
agent these two vector are able to produce high titer of infectious AAV 
particles which can be used to deliver the heterologous gene of 
interest.

    A novel method has been developed for transferring immunity against 
specific types of tumors from a bone marrow donor to a recipient. 
Although there have been major advances in studying the biology of B-
cell and leukemia cancers in recent years, progress in the treatment of 
such diseases has been modest since the treatment of alkylating agents 
more than 30 years ago. An approach using intensive, high-dose 
chemoradiotherapy combined with bone marrow transplantation (to help 
improve tolerance of bone marrow cells to intense therapy) is presently 
being explored by several groups of investigators. However, although 
this type of therapy has improved initial responsive rates, the vast 
majority of patients (90 percent) eventually relapse.
    The current invention provides a method of improving a 
transplantation of hematopoietic cells from a donor to a recipient to 
treat a hematopoietic cell tumor in the recipient comprising immunizing 
the donor's hematopoietic cells with an antigen specific for the 
recipient's hematopoietic cell tumor, and transplanting the donor's 
immunized hematopoietic cells to the recipient. This method offers a 
novel means for conferring immunity against, and thereby treating, B-
cell and leukemia cancers as well as other types of cancers.

A Murine Melanoma Transduced with CCR7 as a Model of Enhanced 
Metastasis to Lymph Nodes

    The current invention embodies a B16 murine melanoma cell line 
which has been stably transduced with the gene for CCR7, a gene which 
promotes the migration of activated dendritic cells into lymphatic 
vessels. This transduced cell line has been shown to metastasize much 
more efficiently to lymph nodes than non-transduced cells. While the 
spontaneous rate of metastasis to lymph nodes is quite low for non-
transduced B16 cells, the inventor has found 200--1400 times more 
melanoma-specific mRNA in the lymph nodes of mice which have been 
injected with the CCR7-expressing melanoma cells. As melanoma in humans 
first metastasizes by invading the lymphatics and migrating to the 
draining lymph nodes, the transduced B16 cell line embodied in this 
invention appears to represent a

valuable model system for identification and testing of agents to be 
used in prevention or reduction of melanoma metastasis via a lymphatic 
route. The cell line is available for licensing via Biological 
Materials License Agreements.
