CD 1d限制性T细胞的定量和定性缺陷已在人类和小鼠自身免疫性疾病中得到证实。为了研究人Vα 24 J αQ T细胞克隆中T细胞受体激活的转录结果,使用DNA微阵列定量来自1型糖尿病和IL-4分泌不一致的同卵双胞胎的克隆在抗CD 3刺激后mRNA水平的变化。激活导致IL-4分泌克隆中226个转录物和IL-4无效克隆中86个转录物的显著调节。这些基因中只有28个是共同的。观察到的差异表明糖尿病Vα 24 J αQ T细胞的无效分化以及不变T细胞在髓系细胞的募集和活化中的作用。
Quantitative and qualitative defects in CD1d-restricted T cells have been demonstrated in human and murine autoimmune diseases. To investigate the transcriptional consequences of T cell receptor activation in human Vα24JαQ T cell clones, DNA microarrays were used to quantitate changes in mRNA levels after anti-CD3 stimulation of clones derived from identical twins discordant for type 1 diabetes and IL-4 secretion. Activation resulted in significant modulation of 226 transcripts in the IL-4 secreting clone and 86 in the IL-4-null clone. Only 28 of these genes were in common. The differences observed suggest both ineffective differentiation of diabetic Vα24JαQ T cells and a role for invariant T cells in the recruitment and activation of cells from the myeloid lineage.
