Interleukin-10 (IL-10) is a pleiotropic cytokine with important immunoregulatory functions whose actions influence activities of many of the cell-types in the immune system. We report here identification and cloning of a gene and corresponding cDNAs encoding a novel homologue of IL-10, designated IL-19. IL-19 shares 21% amino acid identity with IL-10. The(More)
Stimulation of human blood cultures with bacterial lipopolysaccharide (LPS) shows large inter-individual variation in interleukin 10 (IL-10) secretion, which has been shown to have a genetic component of over 70%. Alleles at two microsatellite loci in the 4 kb immediately upstream of the human IL-10 transcription initiation site in 132 individuals from 56(More)
Interleukin-10 (IL-10) is a pivotal immunoregulatory cytokine, influencing many aspects of the immune response. The IL-10 gene is located on chromosome 1 at 1q31-32 and is highly polymorphic. One microsatellite and three single nucleotide polymorphisms (SNPs) have been recorded within the 1.2 kb immediately upstream of the gene, with an additional(More)
Several camptothecin derivatives containing a modified hydroxy lactone ring have been synthesized and evaluated for inhibition of topoisomerase I and cytotoxicity to mammalian cells. Each of the groups of the hydroxy lactone moiety, the carbonyl oxygen, the ring lactone oxygen, and the 20-hydroxy group, were shown to be critical for enzyme inhibition. For(More)
The pathologies of many infectious, autoimmune and malignant diseases are influenced by the profiles of cytokine production in pro-inflammatory (TH1) and anti-inflammatory (TH2) T cells. Interindividual differences in cytokine profiles appear to be due, at least in part, to allelic polymorphism within regulatory regions of cytokine gene. Many studies have(More)
Within the past few years, the focus on cytokine single nucleotide polymorphism (SNP) function and association with human diseases has increased considerably. This third supplement to the Cytokine Gene Polymorphism in Human Disease: On-line database describes the positive associations of cytokine SNPs in human diseases described in articles published from(More)
Interferon lambda-1 (IFN-lambda1/IL-29) is a member of the Type-III interferon family, which contains three ligands: IFN-lambda1, 2 and 3. These three ligands use the same unique heterodimeric receptor composed of CRF2-12 (IFN-lambda-R1/IL-28Ralpha) and CRF2-4 (IL10-R-beta) chains. Like their close relatives, the Type-I interferons, IFN-lambda1, 2 and 3,(More)
The DNA alkylation and sequence specificity of a group of natural and synthetic pyrrolo-[1,4]benzodiazepines [P(1,4)Bs] were evaluated by using an exonuclease III stop assay, and the results were compared with in vitro and in vivo biological potency and antitumor activity. The P(1,4)B antibiotics are potent antitumor agents produced by various(More)
Interleukin-10 (IL-10) is an important regulatory cytokine whose involvement extends into diverse areas of the human immune system. Recent characterization of the promoter and 5' flanking regions has demonstrated the presence of positive and negative regulatory segments in the promoter. In addition, the characterization of two dinucleotide repeat elements(More)
