Hepatitis

59
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

  • 确定关键的T细胞子集和涉及的分子通路.

主要方法:

  • 在免疫缺陷小鼠中利用乙型肝炎疫苗诱导的T细胞.
  • 管理T细胞并分析行为变化 (焦虑类行为).
  • 评估海马细胞增殖,并对CD8+ T细胞进行了转录组分析.

主要成果:

  • 接种乙型肝炎疫苗的T细胞接受者表现出增加的焦虑和降低海马细胞增殖.
  • CD8+ T 细胞,而不是CD4+ T 细胞,是这些效应的主要媒介.
  • CXCR6+ CD8+ T细胞通过CXCL16从质细胞透到大脑中,损害神经发生,并通过TNF-α诱导焦虑.

结论:

  • 在B型肝炎疫苗接种后,质CXCL16调解了CXCR6+ CD8+ T细胞在大脑中招募的过程.
  • 这种机制将疫苗接种与神经发生变化和类似焦虑的行为联系起来.
  • 准这种途径可能为情绪和认知调节提供治疗策略.
