Abstract
The circulating T lymphocytes of a female child with recurrent opportunistic infections were normal in number and phenotype but exhibited poor proliferation and decreased synthesis of the T-cell growth factor interleukin (IL) 2 in response to mitogens. Recombinant IL-2 fully restored the proliferative responses of her T cells, suggesting that her poor immune function was related to IL-2 deficiency. Northern blot analysis of total cellular RNA from the patient's T cells revealed markedly decreased levels of IL-2 mRNA of normal size. In addition, mRNA levels of other lymphokines selectively expressed by T cells, which include IL-3, IL-4, and IL-5, were either severely depressed or absent. The levels of interferon gamma mRNA were moderately decreased, while those of granulocyte-macrophage colony stimulating factor, a lymphokine the production of which is not restricted to T cells, were unaffected. The decreased level of lymphokine mRNA in the patient's T lymphocytes was not from enhanced catabolism but resulted from a diminution in the transcription rate of the affected lymphokine genes. Normal transduction via the T-cell receptor/CD3 complex of biochemical signals necessary for the initiation of lymphokine gene transcription indicated that the defect was distal to the membrane signal-transducing apparatus. The defect is hypothesized to involve a T-cell-specific trans-acting regulatory factor required for transcription of the affected lymphokine genes.
