Tumor necrosis factor alpha (TNF alpha) and lymphotoxin (TNF beta) are cytokines with numerous similar immunoregulatory effects. In pulmonary fibrosis, TNF alpha/beta appears to play a critical role in the regulation of the fibroproliferative response. The human TNF alpha/beta genes are located between the HLA-B and the HLA-DR region. In man 5.5 kb and 10.5 kb of TNF alpha/beta restriction fragment length polymorphic (RFLP) bands have recently been identified by means of enzyme NcoI. TNF alpha/beta production is reported to be correlated to the NcoI RFLP. In some collagen diseases, a decreasing frequency of the 10.5 kb band is reported. The two allele NcoI RFLP of the TNF alpha region, yielding bands of 5.5 kb and 10.5 kb, was investigated in normal Japanese subjects and patients with IIP. The frequency of these bands was not different between normal subjects and patients with IIP. However, in female patients, the frequency of the 5.5 kb band was significantly increased compared with those in the male patients and normal subjects. The increase of this band may have some relation to the pathogenesis of idiopathic interstitial pneumonia.

The relative levels of selected cytokine, interleukin-2 receptor, class II DR and DQ RNAs, and maedi visna virus (MVV) RNA were measured by reverse-transcriptase polymerase chain reaction (RT-PCR) in the lungs of sheep with natural maedi visna virus infection (n = 8) and a group of age/sex/breed-matched MVV seronegative sheep (n = 4). These animals were divided into two groups, irrespective of serostatus, according to the severity of lymphocytic interstitial pneumonia. The severity of lung lesions was determined by clinical sign, lung weight, and lesion sore in the lungs measured by three pathologic parameters. Sheep with lung lesions showed hyperelevated levels of granulocyte-macrophage colony-stimulating factor upregulated gamma-interferon, interleukin 2 receptor, and interleukins 1 beta, 4, and 10 mRNAs. Class II mRNAs were found not to be elevated in the lungs of sheep with lung lesions. Tumor necrosis factor alpha and transforming growth factor beta 1 mRNA levels were similar in all sheep lungs studied. We discuss the major roles played by granulocyte-macrophage colony-stimulating factor and type 2 cytokines in the pathogenesis of this disease and the possible stimulation of the production of these cytokines by viral surface glycoproteins.
