 AB    We have generated several transgenic mouse strains carrying a human
       immunodeficiency virus 1 (HIV-1) NEF/3' long terminal repeat (LTR)
       transgene under control of a T cell-specific promoter-enhancer element,
       showing a depletion of CD4+ T cells in the thymus and periphery. The
       immunological functions of the line with the most dramatic changes in
       lymphocyte populations, B6/338L, were analyzed in greater detail. The
       presence of the transgene in the heterozygous animal is associated with
       a dominant severe immunodeficiency. Older animals develop
       lymph-adenopathy and splenomegaly. CD4+CD8+ and CD4+CD8- single positive
       thymocytes already are depleted in these mice at the earliest stages in
       ontogeny, and peripheral T cells are reduced in frequency and present
       cell surface marker expression, which is characteristic for memory and
       activated T cells. The immunological response of B6/338L mice to several
       viral infections is also greatly impaired. Thus, the HIV-1 NEF/3' LTR as
       transgene in T cells can cause immunodeficiency and disease with
       striking similarities to a known retrovirus-induced immunodeficiency
       called murine AIDS (H. C. Morse III, S. K. Chattopadhyay, M. Makino, T.
       N. Frederickson, A. W. Hugin, and J. W. Hartley. 1992. AIDS. 6:607).
