I had only mild symptoms at first : a slight pain below the breastbone when I swallowed , discomfort that felt like nerves or indigestion .
起初症状还比较轻,仅仅是吞咽时胸骨下方的微痛,类似那种神经紧张或消化不良引起的不适。
The t-cell precursors then go to the thymus , a small organ located under the breastbone , where they are called early thymic progenitors ( etps ) .
然后,t细胞的前体前往胸腺一个位于胸骨下的小器官,在那里,它们被叫做早期胸腺祖细胞(etps)。
Chakraborty and colleagues had previously developed computational models of t-cell development in the thymus , an organ located behind the breastbone through which t cells must pass in order to become mature killers .
About the size of its owner 's clenched fist , the organ sits in the middle of the chest , behind the breastbone and between the lungs , in a moistened chamber that is protected all round by the rib cage .
