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:

SRC-related proto-oncogenes and transcription factors in primary human T cells: modulation by cyclosporin A and FK506. Activation of T lymphocytes induces transcription of genes encoding for lymphokines. Interleukin-2 (IL-2) gene expression is controlled transcriptionally by the cooperative activity of specific trans-activating factors that bind to the IL-2 enhancer. Cyclosporin A (CsA) and FK506 inhibit the production of IL-2 in T lymphocytes at the level of gene transcription. A member of the src gene family, the lymphocyte-specific protein tyrosine kinase, p56lck, has been implicated in IL-2 production. CsA was found not to inhibit lck gene expression, nor the activity of the lck gene product. However, CsA and FK506 inhibit the appearance of DNA binding activity of factors that bind to the NF-AT and AP-1 sites in the IL-2 enhancer. Since the induction of NF-AT and AP-1 is induced by the same stimuli that stimulate IL-2 production, these results indicate that the immunosuppressant action of CsA and FK506 is exerted at the level of these trans-activating factors.
