You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["RNA", "CellLine", "Protein", "DNA", "CellType"].

Please return the output as a JSON object of the format: {"DNA" : ["TAL1", ...], "RNA": ["mRNAs", ...], "CellLine": ["T cells", ...], "CellType": ["monocytes", ...], "Protein": ["IL-2", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

The NF kappa B independent cis-acting sequences in HIV-1 LTR responsive to T-cell activation. The rate of transcription initiation directed by the long terminal repeat (LTR) of HIV-1 increases in response to mitogenic stimuli of T cells. Here we show that the response of the HIV-1 LTR may be governed by two independent sequences located 5' to the site of transcription initiation sequences that bind either NFAT-1 or NF kappa B. The rate of LTR-directed gene expression increased in response to treatment with either a phorbol ester or tumor necrosis factor alpha if either the NFAT-1 or NF kappa B binding sites were deleted, but failed to respond to these mitogenic stimuli if both sequences were absent. The HIV-1 mutant virus containing both NF kappa B and NFAT-1 deletion was able to replicate although at a much decreased growth rate, while the deletion of NFAT-1 alone increased the viral growth rate in Jurkat cells. Neither deletion of NF kappa B nor deletion of NFAT-1 decreased activation of viral replication by phorbol ester.
