Master gene regulators bind to specific genes and control their level of activity, which in turn affects the behavior of cells. In fact, when Foxp3 stops functioning, the body can no longer produce working regulatory T cells. When this happens, the frontline T cells damage multiple organs and cause symptoms of type 1 diabetes and Crohn's disease. However, until now, scientists have barely understood how Foxp3 controls regulatory T cells because they knew almost nothing about the actual genes under Foxp3's purview. </font></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 21pt; mso-char-indent-count: 2.0;"><font size="3"><font color="#000000"><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">科学家们发现这些调节性</span><span lang="EN-US"><font face="Times New Roman">T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">细胞又受到称为</span><span lang="EN-US"><font face="Times New Roman">Foxp3</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">的主</span><span lang="EN-US"><font face="Times New Roman">(</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">导</span><span lang="EN-US"><font face="Times New Roman">)</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">基因调节因子的调控。主基因调节因子约束特定的基因并控制它们的活性水平,依次影响(这些免疫)细胞行为。实际上,当</span><span lang="EN-US"><font face="Times New Roman">Foxp3</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">停止作用,机体就不能再产生调节</span><span lang="EN-US"><font face="Times New Roman">T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">细胞。一旦发生这种情况,第一线的</span><span lang="EN-US"><font face="Times New Roman">T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">细胞就损伤多个器官并导致</span><span lang="EN-US"><font face="Times New Roman">I</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">型糖尿病</span><span lang="EN-US"><font face="Times New Roman">(T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">淋巴细胞攻击胰岛</span><span lang="EN-US"><font face="Times New Roman">B</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">细胞</span><span lang="EN-US"><font face="Times New Roman">)</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">和</span><span lang="EN-US"><font face="Times New Roman">Crohn's</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">病(</span><span lang="EN-US"><font face="Times New Roman">T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">淋巴细胞攻击肠壁细胞)。然而,直到现在科学家们还没有了解</span><span lang="EN-US"><font face="Times New Roman">Foxp3</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">是如何控制调节</span><span lang="EN-US"><font face="Times New Roman">T</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">细胞的,因为他们对于处于</span><span lang="EN-US"><font face="Times New Roman">Foxp3</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman";">控制下的下游基因尚不清楚。</span></font></font></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span lang="EN-US"><p><font face="Times New Roman" color="#000000" size="3"> </font></p></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span lang="EN-US"><font face="Times New Roman" color="#000000" size="3">Researchers in Richard Young's Whitehead lab, working closely with immunologist Harald von Boehmer of the Dana-Farber Cancer Institute, used a DNA microarray technology developed by Young to scan the entire genome of T cells and locate the genes controlled by Foxp3.
