研究目的: |
本研究旨在探讨H1N1感染后继发曲霉感染(HAPA)的潜在机制,特别是固有免疫应答异常与B1a细胞及其分泌的IgG抗体之间的关系。我们的主要目标是明确HAPA与单纯H1N1患者的固有免疫应答之间的区别,并深入研究B1a细胞及其分泌的IgG抗体在防御曲霉感染中的作用。我们还将评估激素治疗对B1a细胞的影响,以及IgG抗体在补偿激素治疗可能导致的免疫功能下降方面的潜在效用。 |

|
Objectives of Study: |
This study aims to investigate the potential mechanisms of secondary Aspergillus infection (HAPA) following H1N1 infection, with a particular focus on the relationship between abnormal innate immune responses and B1a cells along with their secreted IgG antibodies. Our primary objective is to clarify the differences in innate immune responses between HAPA patients and those with H1N1 infection alone and to explore the role of B1a cells and their IgG antibodies in defending against Aspergillus infection. Additionally, we will evaluate the impact of steroid therapy on B1a cells and assess the potential utility of IgG antibodies in compensating for immune function decline that may result from steroid treatment. |
