Abstract：
:Cytokines have been suggested to be involved in the cross talk between the immune and the nervous systems, under normal and pathological conditions. For example, the cytokine interleukin-2 was suggested to be involved in response to CNS trauma and spontaneous regeneration. Here, we examined whether mammalian CNS has an intrinsic potential to produce interleukin-2 and, if so, what its cellular origin is. mRNA sequences encoding for interleukin-2 were detected in brains of humans and rodents. Northern blot analysis revealed the presence of several interleukin-2 transcripts of different sizes in the brain, all recognized by lymphocyte-derived interleukin-2 cDNA probes. One of the transcripts, a high molecular weight form of approximately 5 kb, appeared to be unique to the brain. Reverse transcription and amplification by PCR of human fetal brain mRNA revealed one cDNA product that, upon sequence analysis, showed a high degree of homology with the human lymphocyte-derived interleukin-2 coding sequence. To identify the possible cellular source of the interleukin-2 transcripts within the mammalian brain, we similarly analyzed mRNA of rat brain cells in culture. Northern blot analysis revealed that astrocytes contain transcripts that hybridize with interleukin-2 cDNA probe. These findings point to the astrocytes as a possible source of brain interleukin-2.
