  They become activated and they produce,
  细胞毒性T细胞活化后 开始增殖
• 
  
  eventually, mature cytotoxic T-cells in large numbers.
  最终 产生大量成熟的细胞毒性T细胞
• 
  
  These cells can now kill cells that have the correct signature,
  而这些细胞现在可以杀伤带标记的细胞
• 
  
  and the signature is MHC-1
  这些标记就是MHC-1表面受体
• 
  
  with this foreign antigen associated with it.
  和与其相联的异己抗原
• 
  
  Now, for antibody production it is still a T-cell
  现在 抗体的产生
• 
  
  that recognizes the antigen presenting cell.
  仍是源于T淋巴细胞识别出抗原呈递细胞
• 
  
  But this antigen presenting cell is more likely
  但这种抗原呈递细胞更加类似于
• 
  
  a professional antigen presenting cell,
  专职抗原呈递细胞
• 
  
  or a subset of cells of your immune system
  或者是体内免疫细胞中的一个亚群
• 
  
  that are specialized in ingesting foreign particles and

  displaying their contents to the rest of the immune system.
