    • Methods of inhibiting release of a proinflammatory cytokine from a macrophage are provided. The methods comprise treating the macrophage with a cholinergic agonist in an amount sufficient to decrease the amount of the proinflammatory cytokine that is released from the macrophage, wherein the cholinergic agonist is selective for an α7 nicotinic receptor. Methods for inhibiting an inflammatory cytokine cascade in a patient are also provided. The methods comprise treating the patient with a cholinergic agonist in an amount sufficient to inhibit the inflammatory cytokine cascade, wherein the cholinergic agonist is selective for an α7 nicotinic receptor. Methods for determining whether a compound is a cholinergic agonist reactive with an α7 nicotinic receptor are also provided. The methods comprise determining whether the compound inhibits release of a proinflammatory cytokine from a mammalian cell. Additionally, methods for determining whether a compound is a cholinergic antagonist reactive with an α7 nicotinic receptor are provided. These methods comprise determining whether the compound reduces the ability of a cholinergic agonist to inhibit the release of a proinflammatory cytokine from a mammalian cell. Oligonucleotides or mimetics capable of inhibiting attenuation of lipopolysaccharide-induced TNF release from a mammalian macrophage upon exposure of the macrophage to a cholinergic agonist are also provided. The oligonucleotides or mimetics consist essentially of a sequence greater than 5 nucleotides long that is complementary to an mRNA of an α7 receptor. Additionally, methods of inhibiting attenuation of TNF release from a mammalian macrophage upon exposure of the macrophage to a cholinergic agonist are provided. These methods comprise treating the macrophage with the above-described oligonucleotide or mimetic.
    • 提供了抑制促炎细胞因子从巨噬细胞释放的方法。 所述方法包括用足以减少从巨噬细胞释放的促炎细胞因子的量的胆碱能激动剂处理巨噬细胞,其中胆碱能激动剂对α7烟碱受体具有选择性。 还提供了用于抑制患者中炎性细胞因子级联的方法。 所述方法包括用足以抑制炎性细胞因子级联的量的胆碱能激动剂治疗患者,其中胆碱能激动剂对α7烟碱受体具有选择性。 还提供了确定化合物是否是与α7烟碱受体反应的胆碱能激动剂的方法。 所述方法包括确定化合物是否抑制来自哺乳动物细胞的促炎细胞因子的释放。 另外,提供了确定化合物是否是与α7烟碱受体反应的胆碱能拮抗剂的方法。 这些方法包括确定该化合物是否降低胆碱能激动剂抑制促炎细胞因子从哺乳动物细胞释放的能力。 还提供了能够抑制巨噬细胞暴露于胆碱能激动剂时从哺乳动物巨噬细胞中减少脂多糖诱导的TNF释放的寡核苷酸或模拟物。 寡核苷酸或模拟物基本上由与α7受体的mRNA互补的大于5个核苷酸长的序列组成。 此外,提供了在将巨噬细胞暴露于胆碱能激动剂时抑制TNF释放从哺乳动物巨噬细胞的减少的方法。 这些方法包括用上述寡核苷酸或模拟物处理巨噬细胞。
